Basement emergency anti-floating structure and construction method thereof

Abstract

The invention relates to a basement emergency anti-floating structure and a construction method thereof. The anti-floating structure comprises a dewatering well, a water storage pool, and a water inlet pipe. The water inlet pipe is used for being arranged under a basement, a water inlet hole is formed in the water inlet pipe, the end of the water inlet pipe is communicated with a settlement pipe,one end of the settlement pipe is communicated with the water inlet pipe, and the other end of the settlement pipe extends downwards vertically; a filter box is arranged at the end, away from the water inlet pipe, of the settlement pipe; the outer side wall of the end, away from the water inlet pipe, of the settlement pipe is communicated with a connecting pipe; and a water suction pump is arranged inside the water storage pool and connected with a water draining pipe. The construction method includes the steps that the water storage pool and the dewatering well are dug; the water suction pumpis installed and the water draining pipe is buried; the connecting pipe, the settlement pipe, and a cleaning pipe are embedded in sequence; the filter box is installed at the bottom of the settlementpipe; one end of a pull rope is connected with the filter box, and the other end of the pull rope extends to the basement from the cleaning pipe and is connected with a winding drum; and the water inlet pipe is buried, and supporting rods are inserted into a base layer. According to the basement emergency anti-floating structure and the construction method thereof, underground water can not be smoothly discharged, so that the anti-floating effect of the basement is improved.

Description

technical field [0001] The present application relates to the field of building anti-floating construction, in particular to a basement emergency anti-floating structure and a construction method thereof. Background technique [0002] At present, the basement is widely used in the society. The basement refers to the height of the room floor below the outdoor ground level exceeding one-half of the clear height of the room. Anti-floating measures are required in the construction of the basement, mainly to reduce the occurrence of A condition in which the entire basement is lifted due to the buoyancy of groundwater. [0003] Existing, such as the Chinese patent document announcement number is CN105421500A, the patent name is a kind of basement anti-floating system based on low-level curtain and pumping and depressurization, including a precipitation well mechanism and a horizontal curtain, and the precipitation well mechanism includes a precipitation well, a storage tank, Suct...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there is sediment in the groundwater, and after the sediment enters the precipitation well and the storage tank, it is easy to accumulate in the precipitation well and the storage tank, resulting in the inability of the groundwater to be discharged smoothly, thereby affecting Defects of anti-floating effect
