The utility model discloses a U shaped water collecting and drainage device for strengthening the soft soil foundation, which includes a permeable filter tube and a water collecting pipe connected by a U shaped bottom, with a one-way valve at the bottom of the collecting pipe, a separator in the inner cavity of the collecting pipe, the bottom end of the pressurized trachea connected to the lower part of the inner chamber of the water collecting pipe, and the top of the pressurized pipe and the supercharging and supercharging. The pump is connected, and the top of the water pipe is connected with the outstretched drainage pipe. Under the water pressure difference between the inner cavity of the permeable filter tube and the surrounding soft soil, the pore water in the soft soil passes through the permeable filter pipe into the inner cavity and flows through the one-way valve to the inner cavity of the water collecting pipe. When the water level in the permeable filter tube is high, the pressurized pump works and the pressurized pipe is drained to the water collector. Under the inner cavity, the inner cavity is pressurized to make the score partition move upwards, so that the water of the inner cavity of the water pipe is discharged outwards, and the water level in the water pipe is reduced, thus the water level of the permeable filter tube is reduced, and the water pressure difference is formed again, so the pulse drainage is formed to achieve the effect of rapid drainage and consolidation of the soft soil foundation from top to bottom.

一种软土地基加固处理U形集水强排水装置
本技术涉及软土地基加固工程
,特别涉及一种软土地基加固处理U形集水强排水装置。
技术介绍
现有技术中软土地基加固通常都是采用预压排水固结方法,预压排水固结方法主要有真空预压和堆载预压两种方法,当采用真空预压或堆载预压等方法进行软基加固处理时,一般在软土地基中设置竖向砂井或排水板作为排水通道,在堆载料自重荷载或真空荷载预压下发生排水固结,使得软土地基中孔隙水通过排水通道向外排出,孔隙水压力慢慢消散,有效应力慢慢增长,地基强度逐渐增加,地基固结沉降量绝大部分在施工期内得以消除,从而使软土地基的承载力得到提高,减少工后沉降。但是,堆载预压固结或真空预压固结时,软土中应力差的产生以及传递很慢,难以迅速实现下层的软土固结。造成工期长、造价高、工后沉降幅度大等问题。
