Deep foundation pit drainage system and drainage method

Abstract

The invention relates to a deep foundation pit drainage system and drainage method. The deep foundation pit drainage system comprises a water pumping device and a muddy water treatment device; the water pumping device comprises a water pumping pipe inserted into a soil layer and a crushing mechanism arranged at one end of the water pumping pipe, and the end, away from the crushing mechanism, of the water pumping pipe is communicated with a conveying pipe for conveying muddy water; the end part of the conveying pipe is communicated with the muddy water treatment device, and the conveying pipe is connected with a conveying pump; and the muddy water treatment device comprises a compression mechanism used for separating water and mud in the muddy water and a recycling mechanism used for recycling the separated mud. The drainage method comprises the following steps of S1, equipment arrangement; S2, foundation pit dewatering and water collection, wherein the conveying pump and the compression mechanism are started, the muddy water is separated, and the separated water is collected; and S3, mud collection, wherein the compression mechanism is used for removing residual moisture in the mudto harden the mud into mud blocks, and the recycling mechanism is started to output the mud blocks out of the compression mechanism. The drainage system and drainage method has the effect of improving the utilization rate of the mud and the water.

Description

technical field [0001] The application relates to the technical field of drainage systems in foundation engineering construction, in particular to a deep foundation pit drainage system and a drainage method. Background technique [0002] In the process of building construction, the construction quality of the foundation works determines the overall strength of the superstructure. During foundation engineering construction, the drainage efficiency and quality in the foundation pit are closely related to the efficiency and quality of foundation engineering construction. [0003] At present, in the construction of foundation engineering, the method of dewatering at the well point is used to extract the groundwater in the deep foundation pit, so as to facilitate the foundation construction. The operation method of well point dewatering is to select a plurality of dewatering well points around the foundation pit, insert water filter pipes at the positions of the dewatering well ...

AI Technical Summary

Problems solved by technology

When the water drained through the filter pipe is pumped out of the foundation pit, this part of the water will be input into the municipal sewage and cannot be recycled, resulting in a waste of resources
