Vacuum electroosmosis drainage device for reinforcing soft soil foundation and construction method of vacuum electroosmosis drainage device
The invention relates to the technical field of soft soil foundation reinforcement, and discloses a vacuum electroosmosis drainage device for reinforcing a soft soil foundation, which comprises a metal pipe pile, a drainage pipe, a vacuum pump, a metal pipe and a power supply, the metal pipe pile comprises a pile head, a pile body and a pile end, the pile body is internally provided with a cavity, the side part of the pile body is provided with a suction hole, one end of the drainage pipe extends into the cavity, and the other end of the drainage pipe extends into the vacuum pump. The metal pipe is provided with a plurality of through holes, the negative electrode of the power source is electrically connected with the metal pipe pile, and the positive electrode of the power source is electrically connected with the metal pipe. In addition, the invention further provides a construction method using the device, firstly, the metal pipe pile is used as a vacuum pressure applying and drainage channel, excessive water in a soil body is driven to be gathered and drained through air pressure difference, then electrochemical drainage is conducted by using the metal pipe pile as a cathode and a metal pipe as an anode, and finally the rigid pile is formed by pouring concrete. A series of problems of poor consolidation effect, long period, low bearing capacity and the like of conventional vacuum drainage are solved.
本发明涉及软土地基加固技术领域，公开了一种加固软土地基的真空电渗排水装置，包括金属管桩、排水管、真空泵、金属管以及电源，金属管桩包括桩头、桩身和桩端，桩身的内部设有空腔，桩身的侧部设有抽吸孔，排水管的一端伸入空腔内，排水管的另一端与真空泵连接，金属管设有多个通孔，电源的负极与金属管桩电连接，电源的正极与金属管电连接。此外，本发明还提供了使用该装置的施工方法，首先利用金属管桩作为施加真空压力和排水通道，利用气压差驱动土体中过量的水聚集排出，然后利用金属管桩作为阴极、金属管为阳极进行电化学排水，最后通过灌注混凝土形成刚性桩，解决常规真空排水固结效果差、周期长、承载力低等一系列问题。
