【考案の詳細な説明】本考案は可撓性膜製起伏堰に関するものである。[Detailed explanation of the idea]The present invention relates to an undulating weir made of flexible membrane.

可撓性膜製起伏堰は堰体を形成する例えばゴム引布等の
可撓性膜製包被（袋状体）を少くとも河床部に河を横断
する方向に取り付け、包被内部に連通ずる注排気（水）
管から空気又は水或いはその両者等流体を送り膨張起立
させ或いは包被内部から流体を排出し収縮倒伏させる様
にしたものである（例えば特公昭４０−１１７０２号、
特公昭４４−２３７１号参照）。A flexible membrane undulating weir has a flexible membrane envelope (bag-like body) made of rubber-coated cloth, etc., which forms the weir body, attached to at least the river bed in the direction across the river, and connected to the inside of the envelope. Inlet/exhaust (water)
A fluid such as air or water, or both, is sent through the tube to cause the tube to expand and stand up, or by discharging fluid from inside the envelope to cause the tube to contract and fall down (for example, Japanese Patent Publication No. 11702/1983).
(See Special Publication No. 44-2371).

さてこの種起伏堰に於いて、堰を膨張させた状態におい
て堰体内部で作業する際には、内部作業のための動力、
照明用としての電線ケーブルあるいは安全確保のための
エアホース等の外部と連続した物体を堰体内に入れてお
く必要がある。Now, in this type of undulating weir, when working inside the weir body with the weir inflated, the power for internal work,
It is necessary to put objects that are continuous with the outside, such as electric wire cables for lighting or air hoses to ensure safety, inside the weir body.

ところが堰体は水蜜または気密であり内外部連続した物
体を取り付けるには下記のような問題点がある。However, the weir body is watertight or airtight, and the following problems arise when attaching an object that is continuous inside and outside.

■ 堰体内部に電線あるいはホース等の物体を内部に入
れるためには堰体の取付部を介さなければならない。■ In order to insert objects such as electric wires or hoses into the weir body, they must go through the weir attachment part.

従って取付部の圧縮により内部へ入れた物体の破損ある
いは不通が起こる可能性がある。Therefore, there is a possibility that the object inserted therein may be damaged or interrupted due to the compression of the attachment part.

また内部への貫通体がある部分における堰体取り付けが
煩雑であり作業中の水密、気密に不安がある。Furthermore, the installation of the weir body in the area where there is a penetrating body inside is complicated, and there is concern about watertightness and airtightness during work.

＠ 堰体取付部分を介しても内部へ物体を入れられない
場合は作業性、作業環境の悪化あるいは安全確保ができ
ない状態で作業を行なわねばならない。@ If objects cannot be inserted into the weir body even through the weir attachment part, the work must be carried out in conditions where work efficiency, work environment deteriorates, or safety cannot be ensured.

即ち動力による工具が使用できないため手動による工具
の使用、照明不足、新鮮な空気の不足等が起こり得る。That is, the use of manual tools, lack of lighting, lack of fresh air, etc. may occur because powered tools cannot be used.

本考案は上記問題点を解消するため考究されたものであ
る、以下例示の図面に就いて詳細に説明する。The present invention was developed to solve the above problems, and will be described in detail below with reference to the drawings.

第１図は本考案の起伏堰の概略図、第２図は第１図の丸
で囲むＡ部分の拡大図である。FIG. 1 is a schematic diagram of the undulating weir of the present invention, and FIG. 2 is an enlarged view of the portion A circled in FIG. 1.

第１図に於いて１は堰本体を形成する包被たる可撓性膜
、６は河床、７は上流水、８は注排気（水）管、９はシ
ールシート、１０は空気又は水、１１は包被を河床に取
り付ける金具を示すことは従来と変らない。In Fig. 1, 1 is a flexible membrane that forms the weir body, 6 is a river bed, 7 is upstream water, 8 is an inlet/exhaust (water) pipe, 9 is a seal sheet, 10 is air or water, No. 11 is the same as before, indicating the metal fittings for attaching the envelope to the river bed.

しかし本考案に於いては上記に於いて第２図の如く構成
されている。However, the present invention is constructed as shown in FIG. 2 above.

即ち第２図において１は例えばゴム引布等堰体を形成す
る可撓性膜、２は中央に貫通孔部５を有する可撓性材料
による成型品例えば漏斗を押しひろげた状態のゴム成型
品、３は２の貫通孔部を完全に密閉する物体例えば栓状
ゴム物体、４は２と３を固定して水、気密にするための
締具例えばホースバンドである。That is, in FIG. 2, 1 is a flexible membrane forming the weir body, such as rubber-coated cloth, and 2 is a molded product made of a flexible material having a through hole 5 in the center, such as a rubber molded product with a funnel in an expanded state. , 3 is an object that completely seals the through hole portion of 2, such as a plug-shaped rubber object, and 4 is a fastener, such as a hose band, that fixes 2 and 3 to make them watertight and airtight.

上記２は可撓性膜の河床コンクリート面と接する以外の
部分通常は法面に近い堰の頂部に設ける。The above 2 is usually provided at the top of the weir near the slope surface of the flexible membrane other than the part in contact with the riverbed concrete surface.

３の外周部は常に２と密着して水、気密でなければなら
ないが、外周部を除く部分については堰体が膨張してい
ない時は水、気密でなくても良い。The outer periphery of 3 must always be in close contact with 2 and be watertight and airtight, but the parts other than the outer periphery do not need to be watertight and airtight when the weir is not expanded.

ただし堰体が膨張した場合は水、気密でなければならな
い。However, if the weir body expands, it must be water and airtight.

例えば水膨張式の場合に於いては空気抜孔を設けること
があるが、この為の栓を密閉する物体として用いること
も出来、この際は空気抜孔と貫通孔部を有する成型品は
共用とすることも出来る。For example, in the case of a water-inflatable type, an air vent hole may be provided, but the plug for this purpose can also be used as a sealing object, and in this case, the molded product with the air vent hole and the through-hole part should be shared. You can also do that.

なお２の内径は必要に応じて自由に設計する。Note that the inner diameter of No. 2 can be freely designed as necessary.

さて以上の様に構成されている本考案の起伏堰に於いて
、堰体内に電線、ホースあるいはその他の連続体を入れ
る場合は締具４をゆるめて密閉する物体３を除去しそれ
によって開放した貫通孔部５を介してやれば良い。Now, in the undulating weir of the present invention constructed as described above, when inserting electric wires, hoses, or other continuous bodies into the weir, it is necessary to loosen the fastener 4 and remove the sealing object 3, thereby opening the weir. It may be done through the through hole portion 5.

この時内部へ入れる連続体と貫通孔部の径が違うことに
よって堰体の水、気密が損われる場合は連続体を可撓性
材料例えばゴムテープによって被覆し径を合わせてやる
かまたは間隙部に充填材例えばシーラント又は液状ゴム
を充填してやれば良い。At this time, if the diameter of the continuous body to be inserted into the interior and the diameter of the through hole are different, and the water and airtightness of the weir body is impaired, the continuous body should be covered with a flexible material such as rubber tape to match the diameter, or the diameter of the continuous body may be adjusted to match the diameter of the through hole. It may be filled with a filler such as a sealant or liquid rubber.

以上の様な本考案に於いては下記の様な利点がある。The present invention as described above has the following advantages.

即ち堰体内へ必要なエネルギーあるいは情報その他を堰
体取付部を介すことなく出し入れできる。That is, necessary energy, information, etc. can be taken in and out of the weir body without going through the weir body mounting portion.

従って堰体取付部を介すことによる煩雑さあるいは難点
を除去することができる。Therefore, it is possible to eliminate the complexity and difficulty of using the weir body mounting portion.

また堰体取付部を介しては出し入れできないものについ
ても成型品２の内径を変えることによって出し入れ可能
となる。Also, items that cannot be taken in or taken out through the weir attachment part can be taken in or taken out by changing the inner diameter of the molded product 2.

膜製起伏堰。Attaching the flexible membrane envelope in the direction across the river at least to the riverbed involves sending fluid as a pressure medium into the interior of the envelope to make it expand and stand up, and expel the fluid as a pressure medium from inside the envelope to cause it to contract and fall down. In the weir that is designed to allow the weir to be used, a molded product having a through-hole for passing a continuous object inside and outside the sheath is tightly attached to the sheath, and this through-hole can be sealed with a removable object.
