Method for treating soft soil foundation by accelerating drainage through gas lift
The invention discloses a method for treating a soft soil foundation by accelerating drainage through gas lift. The method comprises the following steps: firstly, determining properties and engineering requirements of the soft soil foundation; then the soft soil foundation is pretreated, jet flow and gas lift combined layered drainage construction is designed according to the investigation result, vertical drainage bodies, air presses, gas lift holes, high-pressure water pumps, rotary spraying rods, gas guide pipes and water guide pipes are included, and according to the design requirements, drainage plates are drilled, the gas lift holes are drilled, a monitoring system is arranged, and pipeline connection is conducted; and finally, high-pressure water jet is combined with gas lift layered drainage. The jet flow technology and the gas lift technology are creatively combined, a crack horizontal drainage channel with a certain depth and width is formed in the soft soil layer through jet flow cutting of the soil layer, the permeability of the soil body is remarkably enhanced, and favorable conditions are created for subsequent gas lift drainage. Therefore, resistance in the subsequent gas lift drainage stage is reduced, and drainage efficiency is improved.
本发明公开了一种通过气举加速排水处理软土地基的方法,首先确定软土地基的性质和工程要求;然后对软土地基进行预处理,且根据勘察结果设计射流结合气举分层排水施工,包括竖向排水体、空气压力机、气举孔、高压水泵、旋喷杆、导气管和导水管,根据设计要求打设排水板、钻设气举孔、布设监测系统、进行管道连接;最后进行高压水射流结合气举分层排水。本发明创造性地将射流技术和气举技术相结合,通过射流切割土层在软土层中形成一定深度和宽度的裂缝水平排水通道,显著增强了土体的渗透性,为后续的气举排水创造有利条件。从而减少后续气举排水阶段的阻力,提高排水效率。
