Hand-shaped connector applied to gas lift type drainage preloading foundation treatment

WU SHIHENG / WANG KANG / SHI LI / YAO KANG

A hand-shaped connector applied to gas lift type drainage preloading foundation treatment comprises a hand-shaped connector body structure and a pneumatic connecting structure. The hand-shaped connector body structure comprises a rectangular connector and a tubular connector connected to the middle of the upper end of the rectangular connector. The pneumatic connecting structure comprises equal-diameter quick connectors, a pneumatic pipe and an equal-diameter straight-through connector. The two equal-diameter quick connectors are symmetrically arranged on the two sides of the pipe type connector. The equal-diameter quick connector is connected with the pneumatic pipe, and an open hole and a sealing ring are arranged at the position, corresponding to the pneumatic pipe, of the top face of the rectangular connector; the pneumatic pipe is connected with the equal-diameter straight-through connector after penetrating through the open hole and the sealing ring and penetrating through the connector body structure. Pore water in a soil body can be promoted to permeate to the drainage plate, and therefore the reinforcement effect of drainage preloading foundation treatment is improved.

一种应用于气举式排水预压地基处理的手型接头，包括手型接头主体结构和气动连接结构；所述手型接头主体结构包括一个矩形接口和连接在矩形接口上端中部的管型接口；所述气动连接结构包括等径快速接头、气动管和等径直通接头，两个等径快速接头对称设置在管型接口两侧；等径快速接头与气动管相连，矩形接口的顶面与气动管相对应的位置设有开孔及密封圈；所述气动管通过穿过开孔及密封圈穿过接头主体结构后与等径直通接头相连。本发明能促进土体中孔隙水向排水板渗透，从而提高排水预压地基处理的加固效果。
