Construction method for reinforcing soft soil foundation through combination of strong drainage preloading and electroosmosis
The invention relates to a construction method for reinforcing a soft soil foundation through combination of strong drainage preloading and electroosmosis, which comprises the following construction steps: S1, a plurality of steel bars are buried into the soft soil foundation to be consolidated by 6 meters or below, the plurality of steel bars are used as positive electrodes of electroosmosis units, and negative electrodes of the electroosmosis units are arranged in transverse pipes and vertical pipes; s2, a high-pressure water pumping assembly is installed on the soft soil foundation to be treated; s3, electrifying the electroosmosis unit to enable the pore water around the steel bar serving as the anode to carry positive charges, and enabling the pore water with the positive charges to gradually flow to the cathode from the anode; and S4, the water collected in the water storage tank is pumped away, the water pumping pipe, the steel bar and the water absorption assembly are taken out, and holes left in the soft soil foundation are filled and tamped with gravel. According to the method, the reinforcing effect of the deep soil layer of the soft soil foundation is achieved by adopting the combined action of strong drainage pre-pressing and electroosmosis.
本发明涉及一种强排水预压联合电渗加固软土地基的施工方法，包括有以下施工步骤：S1，将数根钢棒埋入至待固结的软土地基6米以下，数根钢棒作为电渗单元的正极，横向管和竖向管的内设置有电渗单元的负极；S2，在待处理的软土地基上安装强压抽水组件；S3，对电渗单元进行通电作业，使作为阳极的钢棒周围的孔隙水附带正电荷，带正电荷的孔隙水从阳极逐渐流向阴极；S4，将汇集于储水槽中的水抽走，取出抽水管、钢棒和吸水组件，软土地基中留下的孔洞用碎石进行填充夯实。本发明采用强排水预压和电渗联合作用的方式，达到软土地基深土层的加固效果。
