AI Technical Summary
The increased buoyancy caused by rising groundwater levels leads to deformation of the underground garage floor structure, resulting in water leakage into the garage, which seriously affects the structural safety of the building and the lives and property of residents.
Water collection pits are evenly spaced on the foundation of the underground project and connected to the connecting well through pressure relief pipes. The outside of the pressure relief pipes is covered with dense mesh, and the seepage water is discharged using a lift pump and drainage pipeline.
It effectively avoids deformation of the foundation slab structure caused by rising groundwater levels, prevents secondary damage to underground building structures caused by water leakage, and ensures building safety.

Description
TECHNICAL FIELD
[0001] The utility model relates to underground engineering drainage facility technical field especially relates to a building underground engineering leakage water treatment structure. BACKGROUND
[0002] In recent years due to the rise of underground water level, the underground garage of different cities of existing residential district appears the rise of underground water level in the wet period, when the underground water level rises, the increase of water buoyancy causes the deformation of the underground garage floor structure, the structure deformation causes the damage of underground engineering waterproof, makes the underground water seepage into the underground garage, and even causes the damage of underground garage structure column in different degrees seriously, seriously influences building structure safety and resident life property guarantee, therefore develops a building underground engineering leakage water treatment structure. UTILITARIAN CONTENT
[0003] The utility model aims at providing a building underground engineering leakage water treatment structure, solves the technical problem mentioned in the above background art.
[0004] In order to solve the above technical problem, the utility model adopts the following technical scheme:
[0005] The utility model relates to a building underground engineering leakage water treatment structure, including a plurality of even interval set up in the water collecting pit of building underground engineering foundation, the pressure relief flower pipe of being provided with between every two adjacent water collecting pit, the circumferential wall of each pressure relief flower pipe is evenly provided with pressure relief flower pipe water hole, the outside of pressure relief flower pipe is equipped with dense mesh net, the inside of each water collecting pit is provided with the lift pump, and the output of each lift pump is communicated with the drainage pipeline that extends to the outside of water collecting pit.
[0006] Further, it further includes the communication well that is set up between every two adjacent water collecting pit, and the number of pressure relief flower pipe between adjacent two water collecting pits is two, and two pressure relief flower pipe are used to communicate two water collecting pit and communication well respectively.
[0007] Further, the upper end of each water collecting pit and communication well is provided with the well grate cover plate that is matched with the opening end.
[0008] Further, the pressure relief flower pipe is PE corrugated pipe.
[0009] Compared with the prior art, the utility model has the beneficial technical effects:

[0015] As Figures 1-2 Indicated, a existing building underground engineering leakage water treatment structure, including a plurality of even interval set up in the existing building underground engineering foundation collecting pit 1, every adjacent two collecting pit 1 between the horizontal pressure relief flower pipe 2 of being provided with, the pressure relief flower pipe 2 specifically is PE bellows, each pressure relief flower pipe 2's peripheral wall is evenly provided with pressure relief flower pipe water permeable hole 3, the outside of pressure relief flower pipe 2 is equipped with close mesh gauze 4. The inside of each collecting pit 1 is installed with lifting pump 5, and the output end of each lifting pump 5 is communicated with the drainage pipeline 6 extending to the outside of collecting pit 1.
[0016] The utility model also includes the communicating well 7 of being set up in each adjacent two collecting pit 1 between, the number of pressure relief flower pipe 2 between adjacent two collecting pit 7 is two, and two pressure relief flower pipes 2 are used for communicating two collecting pit 1 and the communicating well 7 between them respectively. In addition, the upper end of each collecting pit 1 and the communicating well 7 is installed with well grate cover plate 8 matched with the opening end thereof.
[0017] The utility model discloses in the specific construction, first adopt the operation surface of the well, the communication well of cutting out in the periphery of the existing building underground engineering (such as underground garage) toothless saw, after the operation surface meets the drilling pipe drawing operation space, carry out horizontal drilling, after the hole, the pressure relief flower pipe of making in advance is drawn into the hole, then again construction well, complete after installing drainage pump and leading out drainage pipeline, finally install well grate cover plate in the well mouth.
[0018] The pressure relief flower pipe in the utility model is located below the bottom plate structure of underground garage, when the underground water level rises, the rising underground water can penetrate to the inside of the pressure relief flower pipe through the water permeation hole of the pressure relief flower pipe and is drained to the well through the pressure relief flower pipe, and the permeated water in the well can be discharged to the outside through the lifting pump and the drainage pipeline, thereby avoiding the deformation of the bottom plate structure of underground garage caused by the rising of underground water level and the increase of water buoyancy, and avoiding the secondary damage to the underground building structure and waterproof system in the season of abundant water period.
