Electro-osmosis combined vacuum preloading sludge curing device and method with horizontally arranged electrodes
The electroosmosis combined vacuum preloading sludge curing device comprises a sample chamber, a drainage plate, a cathode structure, an anode structure, a direct-current power supply, a water-vapor separator and a vacuum pump, water passing openings are formed in the bottoms of the two sides of the sample chamber, and geotechnical cloth is laid on the inner bottom face of the sample chamber; the drain board is horizontally placed on the geotechnical cloth, one side of the drain board is communicated with the water-vapor separator, and the water-vapor separator is connected with the vacuum pump through a drain pipe; the cathode structure is horizontally arranged on the drainage plate, and the cathode structure and the anode structure are connected with the positive electrode and the negative electrode of the direct-current power supply through wires. The invention further discloses a method for solidifying the sludge through combination of electroosmosis and vacuum preloading. The device has the beneficial effects that vacuum preloading and electroosmosis are combined, the drainage plates and the electrodes are horizontally arranged, the vacuum preloading is firstly carried out until the drainage amount is stable, and then electroosmosis is started, so that free water can be discharged to the maximum extent, electroosmosis loss is avoided, and the device has a good reinforcing effect on a soil body.
本发明公开了一种水平布置电极的电渗联合真空预压固化淤泥装置，包括试样室、排水板、阴极结构、阳极结构、直流电源、水汽分离器和真空泵，所述试样室的两侧底部开设有过水口，试样室的内底面铺设有土工布，所述排水板水平放置于土工布上，排水板的一侧与水汽分离器连通，水汽分离器通过排水管与真空泵相连；所述阴极结构水平设于排水板上，阴极结构、阳极结构通过导线与直流电源的正负极相连。本发明还公开了一种电渗联合真空预压固化淤泥的方法。本发明的有益效果为：本发明将真空预压和电渗结合，且水平布置排水板和电极，先进行真空预压至排水量稳定后再开始电渗，可最大程度排出自由水，避免电渗损耗，对土体具有良好的加固效果。
