The explosive-source explosive post that can regularly destroyTechnical field
The utility model relates to a kind of demolition set, the particularly a kind of explosive-source explosive post that can regularly destroy.
Background technology
Existing explosive-source explosive post is made up of shell and interior blasting charge, and several shells are from beginning to end as required, forms the connected mode of more piece.The isolation of blasting charge and underground environment in shell is guaranteed, be that main macromolecular material is made generally with polyethylene, interior blasting charge is generally AN-TNT containing explosive, ammonium nitrate-fuel oil mixture, expanded explosive, emulsion etc., and everyjoint blasting charge 1--3 kilogram uses the 1--100 kilogram at every turn.Because there is defective in existing explosive-source explosive post at the aspects such as installation of sealing, every joint, inventor's SEPARATE APPLICATION " detachable boosting type explosive-source explosive post ", " the explosive-source explosive post group that has the joint that detonates " and " novel detachable boosting type explosive-source explosive post " three utility model patents mainly are that the structure of explosive-source explosive post is improved.
At present in the use of explosive-source explosive post, the main problem that exists is after being detonated by the head joint, thereafter not blast of certain joint, each joint after this will cause also can't explode, make whole explosive effect deficiency on the one hand, unexplodedly on the other hand respectively save residual undergroundly, cause explosive to be in no-console condition, jeopardize social safety.With the performance evaluation of current packaging structure and main blasting charge, the explosive in the explosive-source explosive post can't lose the basic function of explosive more than the ground next year, and this problem is one of explosion thing user difficult problem of being badly in need of solving.
Summary of the invention
The purpose of this utility model is to overcome existing explosive-source explosive post causes potential safety hazard after not exploding in accordance with regulations defective, provides a kind of after not igniting, the explosive-source explosive post that can regularly destroy.
For achieving the above object, the technical solution of the utility model is: a kind of explosive-source explosive post that can regularly destroy, comprise cylindrical shell and gland, on gland, has a detonator hole that is used to install detonator at least, it is characterized in that having around the detonator hole on above-mentioned gland one or one with through hole, a side and through hole corresponding section at gland are provided with annular groove, but the material that timing out is housed in annular groove seals above-mentioned through hole.
Above-mentioned through hole annular groove is 2-4.
The material of above-mentioned timing out is degradative plastics, binding agent, metal etc.
Above-mentioned binding agent is a water-soluble binder.
Above-mentioned metal is easy oxidized metal.
Above-mentioned oxidized metal easily is an iron.
The utility model is that the detonator hole on the gland of existing explosive-source explosive post has through hole on every side, around each through hole, be provided with annular groove, but the material of timing out is housed in annular groove, main blasting charge in being seated in powder column does not have explosion time in accordance with regulations, or because the problem in other operation causes explosive-source explosive post blast not exclusively to remain in when underground, but the material of the timing out in the annular groove will lose efficacy in the time of setting, ambient water just can enter in the explosive-source explosive post by through hole, make the interior explosive of powder column lose the basic function of explosive, becoming with ammonium nitrate is that main chemical substance enters the stratum, even be exposed to ground once more, can not impact environment and personal safety yet.The utlity model has simple in structure, solved the various potential safety hazards that explosive-source explosive post does not detonate and caused safely and effectively, be fit to very much the more place of ambient water and use.

The specific embodiment
Embodiment 1:
Shown in Fig. 1,3, in the upper end ofcylindrical shell 1gland 2 is installed, 2detonator holes 4 that are used to install detonator are arranged on gland, around the detonator hole, be distributed with 4 throughholes 5, on gland with each through hole corresponding position, be provided withannular groove 6, make between cannelure and the through hole to form the bottom and have the cup-shaped in hole, but thematerial 3 that timing out is housed in cup seals above-mentioned through hole.
Embodiment 2:
Shown in Fig. 2,4, on the basis ofembodiment 1, the position ofannular groove 6 is changed, specifically: be provided withannular groove 6 on the gland with on the lower plane of each through hole corresponding position, but thematerial 3 of timing out is housed in annular groove.
In above-mentioned two embodiment, thematerial 3 of timing out is degradative plastics, binding agent, metal etc., and wherein binding agent is a water-soluble binder, and metal is easy oxidized metal, as iron etc.
After explosive-source explosive post does not detonate owing to a variety of causes, the material of timing out will be in the time of setting decomposition failure, the through hole that is closed on the gland is opened, underground ambient water just can enter in the explosive-source explosive post by through hole, make the interior explosive of powder column lose the basic function of explosive, realized the purpose of regularly destroying.
Regularly the time of destroying, can realize by the material of selection timing out and the filling thickness of timing out material.
