Shallow soft soil in-situ solidification construction method
The invention relates to the technical field of foundation reinforcement, and particularly discloses a shallow soft soil in-situ solidification construction method which comprises the following steps: S1, dividing a plurality of treatment areas according to the area of a construction site; s2, the ground of the treatment area is flattened; s3, laying a sand cushion layer; s4, the positions of the plastic drainage plates are determined, and the multiple plastic drainage plates are vertically buried through a plate inserting machine; s5, a main pipeline and branch pipelines are laid, the branch pipelines are connected with the plastic drainage plates, and the main pipeline is connected with the branch pipelines; s6, connecting the main pipeline with a vacuum pump, and starting the vacuum pump to test the sealing performance of the main pipeline and the branch pipeline; s7, a sealing film is laid on the sand cushion layer; and S8, the vacuum pumps are started step by step, part of the vacuum pumps are started according to the pump starting rate of 40% and run for a preset number of days, then part of the vacuum pumps are started according to the pump starting rate of 80% and run for the preset number of days, and finally the rest vacuum pumps are started according to the pump starting rate of 100% and run for the planned running time. According to the technical scheme, the cost can be reduced, and the reinforcing effect is good.
本发明涉及地基加固技术领域，具体公开了浅层软土就地固化施工方法，包括如下步骤：S1、根据施工场地的面积划分若干处理区；S2、平整处理区的地面；S3、铺设砂垫层；S4、确定塑料排水板的位置，通过插板机垂直埋设若干塑料排水板；S5、铺设主管道和支管道，支管道与塑料排水板连接，主管道与支管道连接；S6、将主管道与真空泵连接，启动真空泵测试主管道与支管道密封性；S7、在砂垫层上铺设密封膜；S8、逐步启动真空泵，首先按照40％的开泵率启动部分真空泵，运行预设天数，然后按照80％的开泵率启动部分真空泵，运行预设天数，最后按照100％的开泵率启动余下真空泵，运行真空泵达到计划运行时间。采用本发明的技术方案能够降低成本低且加固效果好。
