Underground diaphragm wall construction method
The invention relates to an underground diaphragm wall construction method. The underground diaphragm wall construction method comprises the steps that concrete enters a steel die through a discharging hopper, a gate plate is arranged in the steel die, when the concrete on the gate plate reaches the preset height, the gate plate is cut off to enable the gate plate and/or the concrete falling on the upper portion of the gate plate to fall along a steel die cavity, and when the concrete falls to the bottom of an underground diaphragm wall, floating mud at the bottom of the underground diaphragmwall overflows due to impact force generated by gravitational acceleration. According to the underground diaphragm wall construction method, the concrete is blocked in the pouring process, the concrete falls to the bottom of the diaphragm wall after reaching a certain height, the floating mud at the bottom of the underground diaphragm wall to overflow through impact force generated by gravity acceleration of the concrete, so that adverse effects generated by the floating mud are effectively prevented, and meanwhile, the problem of segregation in the concrete falling process is relieved.
本发明涉及一种地下连续墙施工方法，混凝土通过下料斗进入钢模，钢模内设置有闸板，当闸板上混凝土达到预定高度时，剪断闸板使其和/或落于其上部的混凝土沿钢模空腔下落，当混凝土落到地下连续墙底部时，由于重力加速度产生的冲击力使地下连续墙底部的浮泥上泛。本发明公开提供了一种地下连续墙施工方法，通过对混凝土浇筑过程中阻挡，达到一定高度后，下落至连续墙底部，通过混凝土重力加速度产生的冲击力使地下连续墙底部的浮泥上泛，有效的防止浮泥产生的不利影响，同时缓解了混凝土下落过程中离析的问题。
