護岸壁や管理型廃棄物最終処分場の護岸壁などの構造物では、ケーソンやブロックなどを並べて護岸壁を構築し、地震などによる地盤変動や不等沈下などにより隣接するケーソンなどの目地部の間隔が変位しても土砂、廃棄物、汚水などの流出を防止するため、目地部を遮水する必要があり、種々の目地材やその遮水構造が提案されている。 For structures such as revetment walls and revetment walls of managed-type waste final disposal sites, caisson and blocks are arranged side by side to construct a revetment wall, and due to ground deformation or unequal subsidence due to earthquakes, etc. In order to prevent the outflow of earth and sand, waste, sewage, etc. even if the interval is displaced, it is necessary to shield the joints, and various joint materials and their water shielding structures have been proposed.

これまでの目地シール構造では、先行するケーソンに予めアンカーボルトと押え板などで目地材を固定しておき、後行のケーソンを設置後、目地材の円筒状部分に中詰材を充填して膨らませることで遮水するものなどがあるが、予め取り付けるため、ケーソンの設置作業中に損傷することがある。 In the conventional joint seal structure, the joint material is fixed in advance to the preceding caisson with anchor bolts and presser plates, etc., and after the subsequent caisson is installed, the cylindrical portion of the joint material is filled with the filling material. There are things that insulate water by inflating, but because they are attached in advance, they may be damaged during caisson installation work.

そこで、隣合うケーソンの対向面に上下方向の溝を形成し、溝の開口をスリット状に狭くしておき、溝内に納まる形状で、しかも開口から抜け出さない寸法の取付部と目地幅より十分に広い幅の遮水部とを有する可撓性材料の目地材を用意し、ケーソンを設置後、目地材の両端部の取付部を対向する溝内に嵌め込んで取り付けることで目地部を遮水することが提案されている（特許文献１、２参照）。 Therefore, a vertical groove is formed on the opposing surface of the adjacent caisson, the opening of the groove is narrowed into a slit shape, and the shape fits in the groove and is sufficiently larger than the mounting portion and joint width that do not come out of the opening Prepare a joint material made of flexible material having a wide water-impervious portion and install the caisson, and then fit the attachment parts at both ends of the joint material into the opposite grooves and install the joint parts. Watering has been proposed (seePatent Documents 1 and 2).

そして、このようなケーソン用の目地材では、溝の開口から確実に抜けないようにするため、取付部の中心に芯材を入れるようにしている。
特開平０６−１１６９２４号公報特開２００５−１４６６５９号公報In such a caisson joint material, a core material is placed in the center of the mounting portion in order to prevent the caisson joint material from coming out of the opening of the groove.

For example, as shown in FIG. 2 (b), the jointmaterial mounting grooves 3, 3 are formed by forming aconcave portion 4 having a rectangular cross section on theend surface 1 a of thecaisson 1 and closing the opening with twoplate materials 5. Anarrow opening 3a and aninternal space 3b are formed as jointmaterial mounting grooves 3 and 3. Furthermore, in this jointmaterial attachment groove 3, 3, in order to prevent damage due to contact between theopenings 3a, 3a and thejoint material 10, around bar 5a is attached to the opening side end of theplate member 5 by welding, The contact is made on the arc surface.

なお、この目地材取付溝３は、開口部３ａが狭幅で内部に空間３ｂが形成されるものであれば、その横断面形状は、矩形に限らず円形など他の形状であっても良く、開口部３ａがケーソン１の端面１ａ上に位置し、空間３ｂがケーソン１内に配置される場合に限らず、鋼材などで構成した別体の目地材取付溝をケーソン１の端面１ａから突き出すように取り付けるようにすることもできる。  As long as theopening 3a is narrow and thespace 3b is formed therein, the cross-sectional shape of the jointmaterial mounting groove 3 is not limited to a rectangle but may be other shapes such as a circle. Theopening 3a is located on theend surface 1a of thecaisson 1, and thespace 3b is not limited to being disposed in thecaisson 1, but a separate joint material mounting groove made of steel or the like protrudes from theend surface 1a of thecaisson 1. It can also be made to attach.

このような目地材取付溝３は、ケーソン１の端面１ａの大きさにもよるが、図４の例では、海側に２箇所、廃棄物投入側になどの反対側に２箇所それぞれ設けられ、これにより、４箇所に目地材１０が施工されるようにしてある。  Such a jointmaterial mounting groove 3 depends on the size of theend face 1a of thecaisson 1, but in the example of FIG. 4, two places are provided on the sea side and two places on the opposite side such as the waste input side. Thereby, thejoint material 10 is constructed in four places.

なお、ケーソン１，１の対向する目地材取付溝３，３は、完全に直線状に対向させる必要はなく、目地材１０の大きさなどによって異なるが、目地材を装着できる程度のずれが生じて対向する状態であっても良い。  The facing jointmaterial mounting grooves 3 and 3 of thecaissons 1 and 1 do not need to be completely opposed to each other in a straight line, and differ depending on the size of thejoint material 10 and the like. And facing each other.

このような対向するケーソン１，１の端面１ａ，１ａの目地材取付溝３，３の間に取り付けられる目地材１０は、例えば図１に示すように、両端部に目地材取付溝３に取り付けられる取付部１１，１１を備え、これら取付部１１，１１を連結して目地部２の変位に追従し得る伸縮部１２が設けられ、ゴムや合成樹脂などの可撓性材料で作られてその可撓性および形状効果で変位に追従させるようにしてある。なお、目地材１０には、必要に応じて可撓性材料の内部に補強材が入れられて外部を可撓性材料とした補強構造が採られたものが用いられる。  Thejoint material 10 attached between thejoint surfaces 1a and 1a of the facing caisons 1 and 1 and the jointmaterial attachment grooves 3 and 3 of the opposingcaisson 1 and 1 is attached to the jointmaterial attachment grooves 3 at both ends as shown in FIG. Theattachment portions 11 and 11 are provided, and theattachment portions 11 and 11 are connected to each other, and an expansion /contraction portion 12 that can follow the displacement of thejoint portion 2 is provided, and is made of a flexible material such as rubber or synthetic resin. The displacement and the shape effect are made to follow the displacement. As thejoint material 10, a material having a reinforcing structure in which a reinforcing material is placed inside a flexible material as required and the outside is a flexible material is used.

この目地材１０では、伸縮部１２がシート状の可撓性材料を環状に接続してその内部に中空部となる空間が形成される大環状部１２ａと、この中空部となる大環状部１２ａの中央部にシート状の可撓性材料の中央部を重ねて連結するとともに、両端部を重ねて環状とされた小環状部１２ｂとで構成されている。また、この目地材１０の小環状部１２ｂの重ね合せ部分が一方の取付部１１とされ、大環状部１２ａの反対側の中央部に可撓性材料のシートを重ねて連結し、その端部が外側に突き出したもう一方の取付部１１としてある。そして、このような横断面形状の目地材１０は、長手方向には、ケーソン１の高さに応じた必要な長さに形成され、複数枚の可撓性材料のシートを接着などで連結することで製造される。  In thisjoint material 10, amacro ring part 12 a in which astretchable part 12 connects a sheet-like flexible material in a ring shape to form a space serving as a hollow part therein, and amacro ring part 12 a serving as this hollow part. The central portion of the sheet-like flexible material is overlapped and connected to the central portion, and the smallannular portion 12b is formed in an annular shape by overlapping both end portions. Further, the overlapping portion of the smallannular portion 12b of thejoint material 10 is used as one mountingportion 11, and a sheet of flexible material is overlapped and connected to the central portion on the opposite side of the largeannular portion 12a. Is the other mountingportion 11 protruding outward. Thejoint material 10 having such a cross-sectional shape is formed in the longitudinal direction to have a required length corresponding to the height of thecaisson 1, and connects a plurality of sheets of flexible material by bonding or the like. It is manufactured by.

このような目地材１０の取付部１１，１１には、目地材取付溝３に装着したときに開口部３ａから抜け出すことがないように、抜け出し防止部材１３が外側から取り付けてあり、装着時には、目地材１０の取付部１１，１１の形状を保持するとともに、吊下げ重量を確保して施工性を向上する。  Theattachment portions 11, 11 of thejoint material 10 are attached with a slip-out prevention member 13 from the outside so as not to slip out of theopening 3 a when the joint material is mounted in the jointmaterial mounting groove 3. While maintaining the shape of theattachment parts 11 and 11 of thejoint material 10, a suspended weight is ensured and workability is improved.

なお、この吊下げに必要な重量は、地上での実験によれば、目地材取付溝に目地材の取付部を挿入するときの抵抗値が１０ｋｇｆ／ｍ程度であり、海中での施工では、目地材の比重を略海水と同程度とし、抜け出し防止材に用いる鋼材の比重を７．８５とすれば、海水による浮力を考慮した必要重量Ｗは、１０÷(８．８５／７．８５)で求められ、略１１．２ｋｇｆとなることから、両側の重量を合わせてＷを１１ｋｇｆ／ｍ以上とすることが好ましい。  In addition, according to the experiment on the ground, the weight required for this suspension is a resistance value of about 10 kgf / m when inserting the joint portion of the joint material into the joint material mounting groove. If the specific gravity of the joint material is about the same as that of seawater and the specific gravity of the steel used for the escape prevention material is 7.85, the required weight W considering the buoyancy due to seawater is 10 ÷ (8.85 / 7.85) Therefore, it is preferable to set W to 11 kgf / m or more by adding the weights on both sides.

この抜け出し防止部材１３は、取付部１１に取り付けたときに外側に突き出して開口部３ａから抜け出さないようにでき、しかも形状の保持と重量の確保の必要から型鋼材などの金属部材が好ましく用いられる。  This slip-out preventingmember 13 can be protruded to the outside when it is attached to the mountingportion 11 so as not to slip out from theopening 3a, and a metal member such as a steel plate is preferably used in order to maintain the shape and ensure the weight. .

この目地材１０では、溝型鋼で抜け出し防止部材１３が構成され、溝部分を背中合わせとして取付部１１，１１の両外側から長手方向に沿って配置してボルトで締め付けて取り付けられる。  In thisjoint material 10, the slip-out preventingmember 13 is made of channel steel, and the groove portions are arranged along the longitudinal direction from both outer sides of the mountingportions 11, 11 with the groove portions back to back, and are attached by tightening with bolts.

このような溝型鋼で構成した抜け出し防止部材１３を目地材１０の取付部１１，１１の長手方向に取り付けると、目地材１０を長手方向に巻回したり、折り畳むことができず、運搬などの取り扱いに支障をきたすことになる。  When the slip-out prevention member 13 made of such a grooved steel is attached in the longitudinal direction of theattachment portions 11 and 11 of thejoint material 10, thejoint material 10 cannot be wound or folded in the longitudinal direction, and handling such as transportation Will be disturbed.

そこで、この目地材１０では、抜け出し防止部材１３を予め取り付ける先付け抜け出し防止部材（先付け型鋼材）１３ａと、運搬後、施工現場で取り付ける後付け抜け出し防止部材（後付け型鋼材）１３ｂとで構成してある。そして、予め取り付ける先付け抜け出し防止部材（先付け型鋼材）１３ａを間隔をあけて目地材１０の取付部１１，１１に取り付けることで、図１（ｂ）に示すように、後付け抜け出し防止部材（後付け型鋼材）１３ｂの取り付け部分を湾曲させることができ、折り畳んで運搬台上に載せることができ、必要に応じてスペーサなどを介して重ねられる。  In view of this, thejoint material 10 includes a front-end slip-out preventing member (front-attached steel member) 13a to which the slip-out preventingmember 13 is attached in advance, and a post-attachment slip-out preventing member (post-attached steel member) 13b attached at the construction site after transportation. . Then, as shown in FIG. 1 (b), a pre-attachment slip-out preventing member (pre-attached steel member) 13a attached in advance is attached to theattachment portions 11, 11 of thejoint material 10 with a space therebetween. (Steel material) 13b can be attached to a curved portion, folded and placed on a carriage, and stacked as necessary via a spacer or the like.

そして、運搬後、施工現場で後付け抜け出し防止部材（後付け型鋼材）１３ｂを取り付ける場合には、予め取り付けた先付け抜け出し防止部材（先付け型鋼材）１３ａの間隔をあけた部分に配置して上下の先付け抜け出し防止部材（先付け型鋼材）１３ａとスポット溶接で連結したり、間隔より長い後付け抜け出し防止部材（後付け型鋼材）１３ｂを重ねてボルトで締め付けて取り付けることで、直線状の形状を確保できるようにする。  And when carrying out the post-attachment prevention member (retrofitting type steel material) 13b at a construction site after transportation, it arrange | positions in the part which opened the space | interval of the pre-attached advance prevention member (pre-attachment type steel material) 13a, and attaches up and down. It is possible to secure a linear shape by connecting with a slip-out prevention member (pre-attached steel material) 13a by spot welding, or by attaching and attaching a post-attachment preventive member (retrofitting type steel material) 13b longer than the interval by tightening with bolts. To do.

次に、このような目地材１０の施工方法について説明する。
目地部２を挟んで対向するケーソン１，１の目地材取付溝３，３の距離（通常は目地間隔Ｄに相当）に合わせて目地材１０の取付部１１，１１を吊り上げることができるように、例えば図２（ａ）に示すように、吊り上げ治具２０を用意する。Next, the construction method of suchjoint material 10 is demonstrated.
Theattachment portions 11 and 11 of thejoint material 10 can be lifted in accordance with the distance between the jointmaterial attachment grooves 3 and 3 of thecaissons 1 and 1 facing each other across the joint portion 2 (usually corresponding to the joint interval D). For example, as shown in FIG. 2A, a liftingjig 20 is prepared.

この吊り上げ治具２０は、略十字状の吊り上げ板２１の一方の両端部２１ａに、目地材１０の小環状部１２ｂを引き伸ばして取付部１１、１１を目地間隔Ｄに合わせて支持するとともに、吊り上げ板２１の直交するもう一方の両端部２１ｂで伸縮部１２の大環状部１２ａを目地部２に吊り下ろすことができるように押し潰して重ねた状態で支持する。  The liftingjig 20 extends the smallannular portion 12b of thejoint material 10 to oneend portion 21a of the substantiallycross-shaped lifting plate 21 to support the mountingportions 11 and 11 in accordance with the joint spacing D, and lifts. The other ends 21b of theplate 21 that are orthogonal to each other are supported in a state where they are crushed and overlapped so that themacro-annular portion 12a of thestretchable portion 12 can be suspended from thejoint portion 2.

こうして吊り上げ治具２０を介して吊り上げた目地材１０を吊り下ろし、両端部の取付部１１，１１が目地材取付溝３，３の空間３ｂ、３ｂ内に位置し、伸縮部１２が開口部３ａ，３ａ間に位置するようにし、抜け出し防止部材１３の重量を利用して吊り下ろすことで、目地材１０の下端から装着していく。  Thejoint material 10 thus lifted via the liftingjig 20 is suspended, theattachment portions 11, 11 at both ends are located in thespaces 3b, 3b of the jointmaterial attachment grooves 3, 3, and thetelescopic portion 12 is theopening 3a. , 3a and hanging from the lower end of thejoint material 10 by using the weight of the pull-out prevention member 13 to hang it.

そして、目地材１の先付け抜け出し防止部材（先付け型鋼材）１３ａの大部分を挿入した状態で、後付け抜け出し防止部材（後つけ型鋼材）１３ｂを現場で取り付け、目地材１０の取付部１１，１１の形状を直線状に保持するとともに、吊下げ重量を確保して吊下げることを繰り返し、目地材１０を目地材取付溝３，３に予めつけてある天端マークまで装着する。  Then, in a state where most of the front-end slip-out preventing member (front-end type steel material) 13a of thejoint material 1 is inserted, the rear-end slip-out preventing member (back-end type steel material) 13b is attached on the site, and theattachment portions 11 and 11 of thejoint material 10 are attached. Thejoint material 10 is mounted up to the top end mark previously attached to the jointmaterial mounting grooves 3 and 3 while maintaining the shape of the straight line and securing the suspension weight.

この後、吊下げ治具２０を取り外し、目地材１０の伸縮部１２の大環状部１２ａの内側にアスファルトマスチックなどの中詰材１４を充填して押し広げ、目地部２の両側に接する遮水状態とする（この中詰材１４の充填は、充填後、ケーソン１，１の安定を待って補充する）。  After that, the suspendingjig 20 is removed, and the fillingmaterial 14 such as asphalt mastic is filled inside the largeannular portion 12a of the expansion /contraction portion 12 of thejoint material 10 and spreads, and the water shielding is in contact with both sides of thejoint portion 2. (The filling of the fillingmaterial 14 is replenished after the filling of thecaissons 1 and 1 after filling).

そして、目地材１０の取付部１１，１１が装着された目地材取付溝３，３の空間３ｂに膨張モルタルなどの充填材１５を充填して固定する。
こうして、１箇所の目地材１０の取付施工が完了する（図３（ａ）参照）。Then, thefiller material 15 such as expansion mortar is filled and fixed in thespace 3b of the jointmaterial mounting grooves 3 and 3 in which the mountingportions 11 and 11 of thejoint material 10 are mounted.
In this way, the installation construction of onejoint material 10 is completed (see FIG. 3A).

この後、図４に示したように、２つの目地材１０を隣接して設けた場合には、これら目地材１０，１０間にアスファルトマスチックなどの間詰材１６を投入し、一層完全な遮水状態を確保するようにする。  Thereafter, as shown in FIG. 4, when twojoint materials 10 are provided adjacent to each other, a fillingmaterial 16 such as asphalt mastic is inserted between thejoint materials 10 and 10, thereby further complete shielding. Ensure water conditions.

こうして目地材１０を施工した状態で、例えば地震などでケーソン１，１が変位して目地間隔Ｄが広がる場合には、図３（ｂ）に示すように、目地材の小環状部１２ｂが引き出されるように広がって遮水状態が維持される。  In the state where thejoint material 10 is thus constructed, when thecaissons 1 and 1 are displaced due to, for example, an earthquake and the joint interval D is widened, the smallannular portion 12b of the joint material is pulled out as shown in FIG. It spreads like a water and the water-blocking state is maintained.

また、地震などでケーソン１，１が変位して目地間隔Ｄが広がると同時に前後にずれるようになる場合には、図３（ｃ）に示すように、目地材１０の小環状部１２ｂが斜めに引き出されるように広がることで遮水状態が維持される。  In addition, when thecaissons 1 and 1 are displaced due to an earthquake or the like and the joint interval D is widened and at the same time shifts back and forth, the smallannular portion 12b of thejoint member 10 is inclined as shown in FIG. The water shielding state is maintained by spreading so as to be drawn out.

この目地材１０およびその施工方法によれば、可撓性材料の伸縮部１２の両端の取付部１１，１１の外側に抜け出し防止材１３を設けたので、取付部１１，１１の外側の抜け出し防止材１３で抜け出しを防止することができ、しかも癖のない装着形状を保持することができるとともに、装着時の重量を確保することもでき、施工性が向上する。  According to thisjoint material 10 and its construction method, the slip-out prevention material 13 is provided outside theattachment portions 11, 11 at both ends of the flexible materialstretchable portion 12, so that the outside of theattachment portions 11, 11 is prevented from slipping out. It is possible to prevent the material 13 from slipping out, and to maintain a wrinkle-free mounting shape and to secure the weight during mounting, thereby improving the workability.

また、金属部材や型鋼材の抜け出し防止部材１３により、可能性材料が外側に位置する場合に比べ、目地材取付溝３，３との摩擦を小さくして装着を容易にすることができる。  In addition, the metal member and the steel plate memberpreventive member 13 can reduce the friction with the jointmaterial mounting grooves 3 and 3 and facilitate the mounting as compared with the case where the possibility material is located outside.

さらに、抜け出し防止部材１３を外側に配置することで、運搬後、装着前に後付け型鋼材１３ｂの取り付けも可能となり、運搬性や取扱い性に優れる。  Furthermore, by disposing the pull-out prevention member 13 on the outside, it is possible to attach the retrofit steel material 13b after transportation and before mounting, which is excellent in transportability and handleability.

この目地材１０およびその施工方法によれば、抜け出し防止部材１３を、取付部１１，１１を挟む両側に対称に取り付けるようにしたので、目地材取付溝３，３への装着の際に前後・左右のバランスを保って吊下げることができ、一層装着など施工を安定した状態で円滑に行うことができる。  According to thisjoint material 10 and its construction method, the slip-out prevention member 13 is mounted symmetrically on both sides sandwiching theattachment portions 11, 11. It can be hung while maintaining the left and right balance, and the installation can be smoothly performed in a stable state, such as further mounting.

さらに、この目地材１０およびその施工方法では、目地材１０の伸縮部１２に、中空部としての大環状部１３ａを設けて中詰材を充填するようにしたので、中詰材１４で膨らませた中空部である大環状部１３ａで目地部２の遮水性を向上することができる。  Furthermore, in thisjoint material 10 and its construction method, the expansion /contraction part 12 of thejoint material 10 is provided with a largeannular portion 13a as a hollow portion so as to be filled with the filling material. The water blocking property of thejoint portion 2 can be improved by themacro-annular portion 13a which is a hollow portion.

次に、この発明の目地材およびその施工方法の他の一実施の形態について、図５により説明する。
この目地材３０は、ゴムや合成樹脂のシート状の膜部材を多重構造として構成したものであり、受圧膜シート３１と、その外側の受圧膜シートより広幅で中間部に折り畳み部３２ａを備えるとともに、両端部に膨らんだ膨出部３２ｂが形成された変位追従膜シート３２と、さらに外側の保護用のゴムなどの保護膜シート３３とを重ね合わせて構成されている。そして、受圧膜シート３１および変位追従膜シート３２は、補強材を挟んだ補強構造とされ、両端部の取付部３４，３４部分は、幅方向に２枚、長さ方向に２枚の補強材が入れられた４プライ構造とされ、中間部分の伸縮部３５は２枚の補強材が入れられた２プライ構造としてある。Next, another embodiment of the joint material and its construction method according to the present invention will be described with reference to FIG.
Thisjoint material 30 is configured by a rubber or synthetic resin sheet-like membrane member having a multi-layer structure, and includes a pressure-receivingmembrane sheet 31 and afolding portion 32a wider in the middle than the pressure-receiving membrane sheet on the outside thereof. The displacement follow-upfilm sheet 32 formed with bulgingparts 32b swelled at both ends and aprotective film sheet 33 such as a protective rubber on the outer side are overlapped. The pressure-receivingmembrane sheet 31 and the displacement follow-upmembrane sheet 32 have a reinforcing structure with a reinforcing material sandwiched therebetween, and theattachment portions 34 and 34 at both ends have two reinforcing materials in the width direction and two in the length direction. 4 is a ply structure, and thestretchable portion 35 in the middle part is a 2-ply structure in which two reinforcing materials are inserted.

このような目地材３０の両端の取付部３４，３４には、抜け出し防止材３６として、山型鋼が取付部３４を挟んで両側に配置され、山型鋼の中央部側が直角に突き出すようにしてボルトで締め付けてある。  In the mountingportions 34, 34 at both ends of thejoint material 30, as anescape prevention material 36, angle steel is arranged on both sides of the mountingportion 34, and the center portion side of the angle steel protrudes at a right angle. It is tightened with.

この抜け出し防止部材３６も、すでに説明したように、長手方向には、一定の間隔をあけて予め取り付ける先付け抜け出し防止部材と運搬後装着前に取り付ける後付け抜け出し防止部材とで構成することで、長手方向に折り畳むことができるようにし、これにより、運搬性や取扱い性を確保する。  As described above, this slip-out preventingmember 36 is also composed of a front-end slip-out preventing member that is attached in advance in the longitudinal direction at a predetermined interval and a post-insertion-preventing member that is attached after transporting before mounting. So that it can be folded, thereby ensuring transportability and handling.

このような目地材３０の目地材取付溝３，３への装着は、すでに説明した目地材１０と同様にして行われる。  The mounting of thejoint material 30 to the jointmaterial mounting grooves 3 and 3 is performed in the same manner as thejoint material 10 already described.

なお、この目地材３０では、取付部３４，３４および抜け出し防止部材３６の取付間隔は一定であり、目地材１０のように小環状部１２ｂの引き出し量で変えることができないため、そのまま目地材取付溝３，３の空間３ｂ、３ｂに吊り下ろして装着する。  In thisjoint material 30, the attachment interval between theattachment portions 34, 34 and the pull-out prevention member 36 is constant, and cannot be changed by the amount of pulling out of the smallannular portion 12 b like thejoint material 10. It is suspended and mounted in thespaces 3b and 3b of thegrooves 3 and 3.

したがって、抜け出し防止部材３６の山型鋼が、たとえば図５（ｂ）に示すように、開口部３ａと必ずしも当接した状態とならないが、充填材１５を充填することで固定され、遮水性や変位に対する追従性などに何ら支障はない。  Therefore, the chevron steel of the slip-out prevention member 36 does not necessarily come into contact with theopening 3a as shown in FIG. 5B, for example, but is fixed by filling thefiller 15, and the water shielding and displacement There is no hindrance to the follow-up performance.

このような目地材３０およびその施工方法によってもすでに説明した目地材１０およびその施工方法と同様の作用効果を奏する。  Thejoint material 30 and its construction method also have the same effects as thejoint material 10 and its construction method already described.

なお、上記各実施の形態では、２つの異なる形状の目地材を例に説明したが、目地材の形状は両端部に取付部を備え、これらをつないで変位に追従できる部分が設けられるものであれば、どのような形状や材料であっても良い。  In each of the above embodiments, the joint material having two different shapes has been described as an example. However, the shape of the joint material is provided with a mounting portion at both ends, and a portion that can follow these displacements by connecting them is provided. Any shape or material may be used.

また、上記実施の形態では、ケーソンの目地に適用する場合で説明したが、ケーソンに限らず他の構造物の目地にも同様に適用することができる。  Moreover, in the said embodiment, although demonstrated in the case of applying to the joint of a caisson, it can apply similarly to the joint of not only a caisson but another structure.
