Vacuum preloading system based on reverse pumping and drainage and reverse vacuum preloading treatment method
The invention discloses a vacuum preloading system based on reverse pumping drainage, which comprises a vacuum pump, a transverse pumping drainage pipeline, a reverse vertical drainage plate and a sealing system, the reverse vertical drainage plate is vertically distributed in mucky soil, the vacuum pump is connected with the transverse pumping drainage pipeline, and the sealing system is connected with the reverse vertical drainage plate. The transverse pumping and drainage pipelines are respectively connected with reverse vertical drainage plates which are densely distributed in the soil body, and a sealing system is laid on the upper surface of the mucky soil; the lower end of the reverse vertical drainage plate is connected with the transverse pumping drainage pipeline above the reverse vertical drainage plate through a branch pipeline. The invention further discloses a method for conducting reverse vacuum preloading treatment through the vacuum preloading system based on reverse pumping and drainage. According to the system, water at the bottom of the reverse vertical drainage plate can be pumped and drained more sufficiently, the water content of the part, penetrating into the soil body, of the drainage plate is larger, and therefore the pumping and drainage efficiency can be improved.
本发明公开一种基于反向抽排的真空预压系统，包括真空泵、横向抽排管道、反向竖直排水板和密封系统，所述反向竖直排水板竖向分布于淤泥质土中，所述真空泵连接横向抽排管道，横向抽排管道分别与密布于土体中的反向竖直排水板连接，所述淤泥质土上表面铺设有密封系统；所述反向竖直排水板的下端通过支管道与上方的横向抽排管道连接。本发明还公开一种采用上述基于反向抽排的真空预压系统进行反向真空预压处理的方法。该系统能够对反向竖直排水板底部的水分进行更加充分的抽排，而排水板深入土体中的部分水分含量更大，因此有利于提升抽排效率。
