Electro-osmosis grouting device and electro-osmosis-biological cementation synergistic soft clay reinforcing method
The invention discloses an electroosmosis grouting device and an electroosmosis-biological cementation synergistic soft clay reinforcement method, the electroosmosis grouting device comprises a soil model box, an electroosmosis device and a grouting device, and the electroosmosis device comprises a power supply, a first electrode and a second electrode arranged around the first electrode; soft clay is contained between the first electrode and the second electrode, the interior of the first electrode is hollow to form a first channel, the inner-layer side wall of the soil model box is a porous side wall, a second channel is formed between the two layers of side walls, and the two electrodes are porous electrodes; the grouting device comprises a first circulating grouting device and a second circulating grouting device. According to the method, firstly, electroosmosis drainage is conducted through the electroosmosis device, then under starting adjustment of the electroosmosis device, biological grout and cementing fluid are injected into the soft clay in the opposite directions through the first circulating grouting device and the second circulating grouting device correspondingly, and cooperative reinforcement of the soft clay is conducted. The grouting efficiency is improved, and the strength and bearing capacity of the reinforced soft clay are greatly improved.
本发明公开了一种电渗注浆装置及电渗‑生物胶结协同加固软黏土方法，电渗注浆装置包括、土壤模型箱、电渗装置和注浆装置，电渗装置包括电源、第一电极和环绕第一电极四周设置的第二电极；第一电极、第二电极之间盛装软黏土，第一电极内部中空形成第一通道，土壤模型箱的内层侧壁为多孔侧壁，且双层侧壁之间形成第二通道，两电极均为多孔电极；注浆装置包括第一循环注浆装置、第二循环注浆装置。本发明首先通过电渗装置进行电渗排水，然后在电渗装置启动调节下，分别通过第一循环注浆装置、第二循环注浆装置方向相对的往软黏土内注入生物浆液、胶结液，进行协同加固软黏土。本发明提高了注浆效率，大大增加了加固后软黏土强度、承载力。
