Drainage plate connector device applied to gas lift type drainage preloading foundation treatment
A drain board connector device applied to gas lift type drainage preloading foundation treatment comprises an inverted trapezoidal connector connected with the bottom of a drain board, and the inverted trapezoidal connector is connected with the first end of a Y-shaped three-way connecting piece through a check valve; the second end and the third end of the Y-shaped three-way connecting piece are respectively connected with one U-shaped pipe, and the ends, far away from the Y-shaped three-way connecting piece, of the two U-shaped pipes are connected with the variable-diameter straight-through joint; and the variable-diameter straight-through joint is connected with the breather pipes on the two sides of the drainage plate, so that a closed passage is formed. The practical construction requirement of an air lift type drainage preloading foundation treatment technology is met, the purpose that compressed air introduced from top to bottom is turned at the bottom of the drainage plate and then flows into a drainage plate core is achieved, and meanwhile the problems that in the plate inserting process, a plate head touches a hard object, breakage, twisting and damage are likely to happen are solved; the problem that the gas lift connector and the drainage plate body are disengaged due to the fact that the casing pipe is pulled out and returned is solved, efficient transmission of consolidation pressure along the depth of the drainage body is guaranteed, seepage drainage of the soil body is promoted, and the consolidation efficiency is improved.
一种应用于气举式排水预压地基处理的排水板接头装置，包括与排水板底部相连的倒梯形接头，倒梯形接头通过止回阀与Y型三通连接件的第一端连接；Y型三通连接件的第二端和第三端分别与一个U型管相连，两个U型管远离Y型三通连接件的一端与变径直通接头相连；变径直通接头与排水板两侧的通气管相连，从而形成封闭通路。本发明满足气举式排水预压地基处理技术的实际施工需要，达到将自上而下通入的压缩空气在排水板底部调转方向，继而流入排水板板芯的目的，同时解决插板过程中板头触碰硬物易产生的断裂扭结损坏，以及套管拔出回带导致的气举接头和排水板板体脱开等问题，保障固结压力沿排水体深度的高效传递，促进土体渗流排水，提高固结效率。
