Top-down manual hole digging foundation assembly type retaining wall construction technology
The invention relates to a top-down manual hole digging foundation assembly type retaining wall construction technology. The technology comprises the following steps that a first section of retaining wall earthwork is excavated; assembling a first section of assembly type protection wall; a retaining wall chuck is assembled at the pithead, a plug pin of the retaining wall chuck is inserted into a reserved hole of the first section of assembly type retaining wall, and the first section of assembly type retaining wall is suspended; excavating a second section of retaining wall earthwork; the deep foundation pit all-in-one machine hoists a second section of assembly type protection wall to the pit bottom through the hoisting tool, and the second section of assembly type protection wall is assembled; the second section of assembly type protection wall is connected with the first section of assembly type protection wall through the U-shaped buckle; and other sections of assembly type protection walls are installed in a circulating and reciprocating mode from top to bottom till all the assembly type protection walls are connected into a whole. The assembly type retaining wall construction device is reasonable in design, assembly type retaining wall construction in the whole deep foundation pit can be completed through the retaining wall chuck on the ground and the deep foundation pit all-in-one machine only through simple combination, assembly and fixing, working hours are saved, the working efficiency is improved, the labor intensity of engineering constructors is reduced, and the construction risk is reduced.
本发明涉及一种自上而下的人工挖孔基础装配式护壁施工工艺，包含如下步骤：开挖第一节护壁土方；组装第一节装配式护壁；在坑口组装护壁卡盘，护壁卡盘的插销插入第一节装配式护壁的预留孔洞内，悬吊第一节装配式护壁；开挖第二节护壁土方；深基坑一体机通过吊装工装将第二节装配式护壁吊装至坑底，组装第二节装配式护壁；U型卡扣将第二节装配式护壁与第一节装配式护壁相连；从上往下循环往复安装其他节装配式护壁，直至所有装配式护壁连接成整体。本发明设计合理，仅需简单的组合装配、固定，即可利用地面之上的护壁卡盘和深基坑一体机完成整个深基坑中的装配式护壁施工，节省了工时，提高了工效，减少了工程施工人员的劳动强度和降低了施工风险。
