Abstract
The utility model discloses a cable tunnel push pipe tube coupling and waterproof connection structure of work well, including setting up in the lining structure of the work well wall of a well, lining structure waters the port that reinforced concrete was connected with the tube coupling after through, after water reinforced concrete and tube coupling, wall of a well lining structure hookup location inlay respectively and be equipped with the rubber waterstop. The rubber stagnant water has water swellable characteristics of meeting, and when concrete interface that groundwater when the tunnel outside was built after through was infiltrated inside the tunnel, when running into the rubber waterstop, rubber waterstop can expand to give the shutoff to the hole of infiltration, reach the purpose of stagnant water.
Description
Technical field
This utility model is related to cable tunnel construction technical field, more particularly to a kind of cable tunnel jacking pipe joints and work
Make well waterproof connecting structure.
Background technology
As Re-search on Urbanization builds constantly fast-developing, Urban Underground infrastructure construction it is advanced, efficiently, reasonability
It is more and more important.Perfect Urban Underground facility is environmental protection, protects resource, beautifies the important step at home.At present on ground
In the tube coupling and active well connecting structure of lower cable tunnel pipe jacking method, usually there is local infiltration phenomenon.Underground outside tunnel
Water penetrates into tunnel internal by the concrete interface of first after-pouring, can bring disaster to the safe application performance of underground utilities.
Utility model content
To overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of cable tunnel jacking pipe joints and work
Make well waterproof connecting structure.
This utility model is that the technical scheme for solving its technical problem employing is：
Cable tunnel jacking pipe joints and active well waterproof connecting structure, including the inner lining structure for being arranged at the active well borehole wall,
The inner lining structure pours the port that armored concrete is connected with tube coupling after passing through, it is described after pour armored concrete and tube coupling, the borehole wall
The link position of inner lining structure is embedded with respectively rubber fastening band.
Further, distance is left between the inner lining structure of the outer tube wall of tube coupling and the active well borehole wall.
Further, the rubber fastening band is the rubber fastening band of circle closing.
The beneficial effects of the utility model are：A kind of cable tunnel jacking pipe joints that this utility model is provided are prevented with active well
Water attachment structure, armored concrete is poured after and is embedded with rubber fastening band respectively with tube coupling, the link position of borehole wall inner lining structure.
The characteristics of rubber water-proof carries water-swellable, when the subsoil water outside tunnel penetrates into tunnel internal by the concrete interface of after-pouring
When, when running into rubber fastening band, rubber rubber fastening band can expand, and so as to the hole of infiltration is blocked, reach the mesh of sealing
's.
Description of the drawings
Fig. 1 is section structure schematic diagram of the present utility model.
Specific embodiment
This utility model is described further below in conjunction with accompanying drawing and example.
As shown in figure 1, a kind of cable tunnel jacking pipe joints of the present utility model and active well waterproof connecting structure, including setting
The inner lining structure 1 of the active well borehole wall is placed in, the inner lining structure 1 pours the port that armored concrete 2 is connected with tube coupling 3 after passing through,
Armored concrete 2 is poured after described and is embedded with rubber fastening band 4 respectively with tube coupling 3, the link position of borehole wall inner lining structure 1.Specifically
Ground, the rubber fastening band 4 is the rubber fastening band of a circle closing.
The characteristics of rubber fastening band 4 has water-swellable, when the subsoil water outside tunnel is oozed by the interface of concrete 2 of after-pouring
When entering tunnel internal, when running into rubber fastening band 4, rubber fastening band 4 can expand, and so as to the hole of infiltration is blocked, reach
To the purpose of sealing.
Distance is left between the outer tube wall of tube coupling 3 and the inner lining structure of the active well borehole wall.
The above, simply preferred embodiment of the present utility model, this utility model is not limited to above-mentioned enforcement
Mode, as long as it reaches technique effect of the present utility model with identical means, should all belong to protection domain of the present utility model.
