SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a tooth-type water-swelling water stop bar protected prefabricated component box body, which aims to solve the problems in the background technology and prevent the prefabricated component box body from water inflow.
In order to achieve the purpose, the utility model provides the following technical scheme:
tooth formula meets prefabricated component box of water inflation sealing rod protection includes: foundation ditch 1, prefabricated component box 2, meet water inflation sealing rod 3, immersible pump 4, drain pipe 5, check valve 6, apron 7.
The foundation pit 1 is dug at a designated position in advance;
the prefabricated component box body 2 is positioned in a foundation pit 1 dug in advance, a return-shaped groove is formed in the prefabricated component box body and used for filling a water swelling water stop bar 3, a reservoir is formed in the prefabricated component box body and used for placing a submersible pump 4, and a pore passage is formed in the prefabricated component box body and used for placing a drain pipe 5;
the water-swelling water stop strip 3 is filled in a return-shaped groove formed in the prefabricated component box body 2;
the submersible pump 4 is arranged at the bottom of the prefabricated part box body 2 at the left front position in a reservoir reserved in the prefabricated part box body 2;
the drain pipe 5 is placed in a hole channel reserved in the prefabricated part box body 2;
the check valve 6 is connected to the tail end of the drain pipe (5) and communicated with a city sewer pipeline;
the cover plate 7 covers the upper part of the prefabricated part box body 2, and the upper and lower reserved gaps of the return-type plate on the cover plate 7 and the water-swelling water stop strip 3 before water swelling are 2 mm.
When apron 7 moves down to given terminal point, apron 7 "return" the below of template and the water-swelling sealing rod 3's of meeting before the water inflation top reservation have 2mm clearance, and when the external infiltration of box comes in, just can make the water-swelling sealing rod 3 meet the water inflation, all irregular surfaces, cavity and the clearance of tooth seam can be full of to its inflation face, produces huge contact pressure simultaneously, thoroughly prevents the seepage. The pore that 3 below of water-swelling sealing rod were met can also be arranged unnecessary water to the inside cistern of prefabricated component box 2 in, by the extraction of immersible pump 4, arrange urban sewer pipe through drain pipe 5 in, the water backward flow in the urban sewer pipe can be prevented to the check valve 6 of 5 end-to-end connections of drain pipe, further guarantees the waterproof nature of prefabricated component box 2 to realize sealed waterproof effect.
Advantageous effects
Compared with the existing lifting type underground ring main unit, the lifting type underground ring main unit has the beneficial effects that: the problem of when burying looped netowrk cabinet apron sealing not tight and lead to during ground ponding infiltrates the foundation ditch under the over-and-under type is solved. The long-term ponding of foundation ditch can't be discharged and lead to the looped netowrk cabinet to intake, causes the looped netowrk cabinet to damage the problem that takes place the incident.
The system is simple in structure, easy to manufacture and install, not prone to damage, high in practicability and capable of being popularized in a large range
The box body is simple and convenient to manufacture, high in accuracy, good in waterproof performance and wide in applicability.
