Soft soil foundation efficient treatment method combining gas lift with surcharge preloading
The invention discloses an efficient soft soil foundation treatment method combining gas lift with surcharge preloading, which is suitable for surcharge preloading drainage treatment of a soft soil foundation, and comprises the following steps: S1, mounting a joint at the bottom of a drainage plate for connecting a breather pipe; s2, a breather pipe is connected with the connector at the bottom, and the breather pipe and the drainage plate are hit into the soft soil foundation together through a plate hitting machine; s3, after all the drainage plates are driven into the soft soil foundation, a sand cushion layer is laid; s4, an air lift pipeline is laid on the sand cushion layer and connected with an air compressor, and the air lift pipeline extends to all the drainage plates from the air compressor; s5, the gas lift pipeline is connected with the ventilation pipe, and two layers of non-woven fabrics are laid on the gas lift pipeline; and S6, step-by-step stacking is started when the machine enters the field, and meanwhile air lifting is conducted by intermittently starting an air compressor. Positive-pressure gas with certain pressure and flow velocity is introduced into the bottom of the drainage plate through the gas lift pipeline, the positive-pressure gas drives water stored in a plate core of the drainage plate to be discharged out of the earth surface in a gas-water two-phase flow mode, and the soil consolidation pressure is remarkably improved.
本发明公开了一种气举联合堆载预压的软土地基高效处理方法，适用于软土地基的堆载预压排水处理，包括：S1：在排水板的底部安装接头，用以连接通气管；S2：通气管与上述底部的接头相连，通过打板机与排水板一同打设进软土地基内；S3：待排水板全部打入软土地基后，铺设砂垫层；S4：将气举管路铺在砂垫层上方，且与空气压缩机相连，并由空气压缩机处延伸至各个排水板处；S5:将气举管路与通气管相连，并在气举管路上铺设两层无纺布；S6：机械进场开始逐级堆载，同时通过间歇性开启空气压缩机进行气举。本发明通过气举管路在排水板底部通入一定压力和流速的正压气体，正压气体驱动排水板板芯存水以气水两相流的形式排出地表，显著提升土体固结压力。
