Circulating pressure vacuum preloading pile-loading soft foundation reinforcing device and reinforcing method
The invention relates to a circulating pressure vacuum preloading pile-loading soft foundation reinforcing device and method, and belongs to the technical field of soft foundation reinforcing, the circulating pressure vacuum preloading pile-loading soft foundation reinforcing device comprises a preloading system and a dewatering system which are arranged in a soft foundation, the preloading system comprises a drainage plate and a preloading vacuum pump, and the dewatering system comprises a dewatering pipe, a connecting pipe and a dewatering vacuum pump; the drain board and the downcast pipe are inserted below the soft foundation, and the drain board is communicated with the preloading vacuum pump; the downcast vacuum pump is communicated with the downcast pipe through a connecting pipe, and the connecting pipe is provided with a communicating valve. The preloading system and the dewatering system operate at the same time, and vacuumizing and draining are conducted; when the precipitation effect is reduced, the precipitation vacuum pump closes the adjusting communication valve, the connecting pipe is communicated with the atmosphere, and a forward pressure stage difference is formed between the precipitation pipe and the drainage plate, so that water in the soft foundation is gathered and drained towards the drainage plate; and then the dewatering vacuum pump is communicated and started again, so that a negative pressure stage difference is formed between the dewatering pipe and the drainage plate, water in the soft foundation is gathered and drained towards the dewatering pipe, the dewatering speed is accelerated alternately and repeatedly, and the dewatering efficiency is effectively improved.
本申请涉及循环压力真空预压堆载软基加固装置及加固方法，属于软基加固技术领域，其包括设于软基内的预压系统和降水系统，预压系统包括排水板和预压真空泵，降水系统包括降水管、连接管和降水真空泵，排水板和降水管插设于软基下，排水板与预压真空泵连通；降水真空泵与降水管通过连接管连通，连接管上设有连通阀。预压系统和降水系统同时运行，抽真空排水；降水效果下降时，降水真空泵关闭调节连通阀，连接管与大气连通，降水管与排水板之间形成正向压力级差，使软基内的水向排水板汇聚排水；而后降水真空泵再次连通启动，使降水管与排水板之间形成负向压力级差，使软基内的水向降水管汇聚排水，交替往复加快降水速度，有效提高降水效率。
