Mucky soil dewatering device and application thereof

Abstract

The invention relates to a mucky soil dewatering device and application thereof. The device comprises a bamboo pipe drainage mechanism, a groove working mechanism and a water collecting well mechanism. The groove working mechanism comprises a deep groove, a side wall working face and filling sand; the deep groove is formed in a foundation pit project; the wall face of the deep groove is a lateral working face; bamboo ribs are inserted into the inclined upper portion of the side wall working face through a pressure device; and the filling sand is arranged in the deep groove after a water collecting well system is arranged. The water collecting well mechanism comprises a water collecting well body, a concrete layer, a stainless steel filter screen, a water outlet pipe and a water pump; a water collecting well is arranged below the deep groove; the concrete layer is poured on the periphery of the water collecting well; the stainless steel filter screen covers the water collecting well; and the water outlet pipe is inserted into the water collecting well. The water pump is connected to pump water from the water collecting well. The mucky soil dewatering device is used for a precipitation project, the bamboo pipe drainage system, the working face system and the water collecting well system are applied, dewatering and precipitation of mucky soil can be achieved through the steps of deep groove excavation, bamboo pipe drainage, water collecting well water collection, deep groove filling sand and the like, and the mucky soil dewatering device has great significance in mucky soil layer self-flowing drainage and environment protection.

Description

technical field [0001] The invention relates to the technical field of precipitation engineering, in particular to a muddy soil dehydration device and its application. Background technique [0002] Groundwater has adverse effects on underground engineering. In many construction projects, excavation and dewatering are often encountered. Commonly used dewatering methods include open ditch method, hidden ditch method, light well point method, deep well point method, etc. It can be seen that the ground is used as a horizontal working surface for general foundation pit underground engineering precipitation, and wells are drilled vertically on it to drain water vertically. In the actual silty soil layer, there are often many problems in the precipitation process of vertical drainage wells, because silty soil is soft soil, which has three highs and two lows (high compressibility, high water content, high rheology and creep, low strength and low permeability), so drainage is very d...

AI Technical Summary

Problems solved by technology

In the actual silty soil layer, there are often many problems in the precipitation process of vertical drainage wells, because silty soil is soft soil, which has three highs and two lows (high compressibility, high water content, high rheology and creep, low strength and low permeability), so drainage is very difficult

[0003] The existing vacuum pumping method has a certain effect on improving the drainage efficiency of silty soil, but the time is too slow, and the artificially formed drainage channels will automatically heal over time, resulting in gradual deterioration of the drainage effect. In summary, the drainage of silty soil Methods urgently need to develop new techniques
