Electroosmosis and vacuum preloading combined underwater soft soil foundation treatment method
The invention provides an electro-osmosis combined vacuum preloading underwater soft soil foundation treatment method. An electro-osmosis combined vacuum preloading system comprising an electric waterproof system and an electro-osmosis-vacuum drainage system is used; the electric waterproof system is arranged above and beside the electroosmosis-vacuum drainage system; when the electroosmosis-vacuum drainage system drains water from the electroosmosis-vacuum drainage area, pore water moves from an anode to a cathode of the electroosmosis-vacuum drainage system under the action of an electric field and vacuum pressure and is discharged through a vacuum pump; the electric water insulation system comprises a horizontal water insulation belt and a vertical water insulation belt which are constructed by conductive drainage plates or metal electrodes, and a potential gradient opposite to the hydraulic gradient around the drainage consolidation treatment area is formed between a cathode and an anode of the electric water insulation system, so that water in the drainage consolidation treatment area and water in the surrounding area are isolated; water in the surrounding area is prevented from flowing back when the electroosmosis-vacuum drainage system drains water; the method is convenient to construct, good in waterproof effect and capable of effectively achieving drainage consolidation of underwater soft soil.
本发明提出一种电渗联合真空预压的水下软土地基处理方法，使用包括电动隔水系统、电渗‑真空排水系统的电渗联合真空预压系统；电动隔水系统设于电渗‑真空排水系统上方及旁侧；电渗‑真空排水系统对电渗‑真空排水区域排水时，孔隙水在电场和真空压力作用下由电渗‑真空排水系统的阳极向阴极移动并通过真空泵排出；所述电动隔水系统包括以导电排水板或金属电极构建的水平隔水带和竖向隔水带，其阴极、阳极之间形成与排水固结处理区域周围水力梯度相反的电势梯度，以在排水固结处理区域与周围区域的水体间形成隔离；避免在电渗‑真空排水系统排水时周围区域的水发生回流；本发明施工便捷，隔水效果好，可有效实现水下软土的排水固结。
