Such treatment is costly and has certain safety hazards. The new technology of water discharge and decompression anti-floating is to set drainage holes on the bottom plate of the basement to connect the outdoor groundwater with the indoor drainage ditch, and control the groundwater level around the underground building below the critical water level of floating, thereby reducing the buoyancy of groundwater on the building. This method has simple principles, advanced technology, simple construction and good economy.

The municipal pipeline is connected, and the pressure relief assembly 6 includes a fixed pipe 61, a filter pipe 62, a connecting sleeve 63 and a pressure valve 64. The upper end of the fixed pipe 61 is arranged inside the decompression chamber 2, the outer wall of the upper end of the fixed pipe 61 is fixed to the inner wall of the connecting sleeve 63, and the top of the connecting sleeve 63 is fixed to the pressure valve 64; the lower end of the fixed pipe 61 extends into the soil layer 4, and a water inlet hole 611 is opened at the lower end of the fixed pipe 61. The filter pipe 62 is detachably connected to the inside of the lower end of the fixed pipe 61, and the inside of the filter pipe 62 is connected to the water inlet hole 611.

[0031] Through the setting of the decompression chamber 2, the accumulated water under the basement floor 1 is discharged into the decompression chamber 2 through the pressure relief component 6, and is sucked by the water pump 7, and then discharged to the municipal drainage system through the drain pipe 9; the decompression chamber 2 is lower than the basement floor 1, which can effectively prevent the basement floor 1 from being polluted by the accumulated water; through the setting of the pressure valve 64 in the pressure relief component 6, constant-pressure drainage can be achieved according to the pressure of the accumulated water, making the pressure relief component 6 more flexible and convenient, and through the triple filtration of the filter layer 3, the fixed pipe 61 and the filter pipe 62, impurities in the accumulated water can be effectively filtered to prevent the accumulated water from affecting the basement environment.

[0032] Furthermore, a fan-shaped matching groove 612 is opened inside the fixed tube 61, and an annular groove 613 is opened inside the fan-shaped matching groove 612; the filter tube 62 includes a mounting tube 621 and a fan-shaped matching block 623, and the middle part of the mounting tube 621 is a filter screen 622; the fan-shaped matching block 623 is fixed to the outer wall of the mounting tube 621, and the fan-shaped matching block 623 matches the fan-shaped matching groove 612 and the annular groove 613.

Through the setting of the fixed anchor rod 8, the pressure below the basement floor 1 can change rapidly, and the pressure relief component 6 can provide auxiliary fixation for the basement floor 1 when it is too late to relieve pressure, thereby further improving the stability of the basement structure of the medical building.

[0044] The method of using the utility model is:

[0046] When the filter tube 62 needs to be installed, after aligning the fan-shaped matching block 623 with the fan-shaped matching groove 612, the filter tube 62 is pressed down to the lower part of the fixed tube 61. When the upper and lower groups of fan-shaped matching blocks 623 of the filter tube 62 are respectively aligned with the two annular grooves 613 in the middle and lower parts of the fixed tube 61, the filter tube 62 is rotated so that the fan-shaped matching block 623 is clamped in the annular groove 613; the limit block 625 cooperates with the limit groove in the annular groove 613. During the process of installing and removing the filter tube 62, the filter tube 62 is rotated forcefully, and the limit block 625 can press down the reset spring 626, so that the limit block 625 moves downward, which is convenient and quick.
