Device and method for reinforcing soft soil foundation through combination of strong drainage preloading and electroosmosis
The invention discloses a device and method for reinforcing a soft soil foundation through combination of strong drainage preloading and electroosmosis, and relates to the technical field of soft soil foundation reinforcing engineering. The device for reinforcing the soft soil foundation through the combination of strong drainage preloading and electroosmosis comprises at least one drainage assembly, the drainage assembly comprises at least one strong drainage plate and an electroosmosis unit, the strong drainage plate is coated with a filter membrane, a drainage channel is formed between the strong drainage plate and the filter membrane, the strong drainage plate is connected with a Venturi tube, and the interior of the Venturi tube is hollow to form a jet flow inner cavity of which the front and back are correspondingly connected with a fluid inlet and a fluid outlet; and the electroosmosis unit comprises an anode and a cathode which are matched for use, the anode is a steel bar inserted into the soft soil foundation, the cathode is an electrode arranged in the drainage channel, and the electrode and the steel bar are matched to enable pore water with positive charges to permeate the filtering membrane and flow into the drainage channel. The soft soil foundation can be reinforced, the consolidation effect of the deep layer part and the shallow layer part is further improved, and the void ratio of the soil body is reduced.
本发明公开了一种强排水预压联合电渗加固软土地基的装置及方法，涉及软土基加固工程技术领域，强排水预压联合电渗加固软土地基的装置包括至少一个排水组件，其中，排水组件包括至少一个强排水板，强排水板包覆有滤膜，强排水板与滤膜之间构成有排水通道，强排水板连接有文丘里管，文丘里管内部中空以形成前后分别与流体入口、流体出口相连的射流内腔；以及电渗单元，电渗单元包括配合使用的阳极和阴极，阳极为插入到软土地基中的钢棒，阴极为置入到排水通道中的电极，电极和钢棒配合以使带正电荷的孔隙水渗透过滤膜流入排水通道。本发明能加固软土地基，深层部分和浅层部分的固结效果都得到进一步提高，降低了土体的孔隙比。
