Description

Anti-overflow system of water collection pit matched with ground reservoir drainage pressure-reducing system

Technical Field

The utility model relates to the technical field of basement drainage decompression, in particular to an overflow preventing system of a water collecting pit matched with a basement drainage decompression system.

Background

The problem of anti-floating of basement is the difficult problem that often appears, and huge water pressure can cause the bottom plate to come up, causes the structure fracture and appear oozing water phenomenon. The general schemes for solving the anti-floating problem are adding anti-pulling anchor rods or anti-pulling piles, thickening a bottom plate, actively draining water, reducing pressure and lowering water level, and the like. The principle of releasing the pressure of the discharged water to solve the anti-floating problem is to release the groundwater under the bottom plate and reduce the water pressure. The released underground water is discharged into the water collecting pit through the ground drainage system, and then the underground water is discharged by the water suction pump.

In areas with abundant groundwater amount, such as deep buried depth of a basement or better ground rock and soil permeability, particularly in severe weather, such as storm, typhoon, and the like, the water yield of a water discharge hole is very large, the water suction pump needs to work for a long time, when a switch of an electric switch is tripped or suddenly encounters a power failure condition due to easy burnout of a motor, the groundwater cannot be discharged, overflows and spreads after the water collection pit is fully accumulated, the ground warehouse can be immersed, and safety accidents can be caused in nearby elevator shafts. The water yield of each water discharge hole is different, and the problem that part of the water collection pits are full is high in water storage speed and water overflows exists.
