Equivalent diaphragm wall construction system and method used under low clearance condition
The invention discloses an equivalent diaphragm wall construction system and method used under a low clearance condition. The equivalent diaphragm wall construction method comprises the steps that equivalent calculation is conducted, a traditional rectangular diaphragm wall reinforcement cage is equivalently replaced with cylindrical reinforcement cages with certain intervals, and the equivalent stiffness of a calculator is calculated; a second section of reinforcement cage is hoisted by a hoisting machine and lowered to the position making contact with the top of a first section of reinforcement cage; the first section of reinforcement cage and the second section of reinforcement cage are subjected to butt joint construction by constructors, and butt joint is completed through welding; and after hoisting and lowering of the whole equivalent diaphragm wall reinforcement cage are completed, grouting construction is conducted, and finally construction of an equivalent diaphragm wall is completed. According to the equivalent diaphragm wall construction system, the traditional diaphragm wall reinforcement cage is replaced with the multiple sections of cylindrical reinforcement cages, and the cost of the construction system is reduced through cooperation of the hoisting machine, a clamping mechanism, the multiple sections of reinforcement cages and other structures; and according to the equivalent diaphragm wall construction method, through equivalent calculation of the stiffness of the diaphragm wall, reinforcement design of the equivalent diaphragm wall is completed, and the traditional diaphragm wall reinforcement cage is replaced with the multiple sections of cylindrical reinforcement cages.
本发明公开了一种低净空条件下使用的等效连墙施工系统及方法，等效计算，利用具有一定间距的圆柱形钢筋笼等效替代传统地矩形连墙钢筋笼，计算器等效刚度；起吊机起吊第二节钢筋笼，下放至与第一节钢筋笼顶部相接触的位置；施工人员将第一节钢筋笼和第二节钢筋笼进行对接施工，通过焊接完成对接；当整副等效地连墙的钢筋笼吊装下放完成后，进行灌浆施工，最终完成等效地连墙的施工。本申请的系统通过多段圆柱形钢筋笼来代替传统地连墙钢筋笼，采用起吊机、卡位机构和多节钢筋笼等结构的配合，降低施工系统的成本；该施工方法通过对地连墙看完刚度的等效计算，完成了等效地连墙的配筋设计，由多段圆柱形钢筋笼替代传统地连墙钢筋笼。
