超深地连墙钢筋笼吊装设计分析与实践

Analysis and practice for hoisting design of thedeep and overweight diaphragm wall reinforcing cage

超深地连墙施工的难点主要是钢筋笼的吊装施工,尤其是对于深度超过60 m,重量超过90 t的钢筋笼,其吊装难度更大。对杭州地铁超深超重地连墙钢筋笼吊装设计进行了分析,提出了实际吊装施工中需要考虑的问题与注意的事项,并对吊装工况分析,提出吊装设计计算及工程实践中遇到的实际问题及对策。

The difficulty of the ultra-deep connecting wall construction is mainly the lifting construction of the steel cage,especially for the steel cage with a depth of more than 60 m and a weight of more than 90 tons,the lifting is more difficult.Analyzed the hoisting design of the reinforcing bar cage on the super-deep and super-heavy ground of Hangzhou Metro,put forward the problems and precautions in the actual hoisting construction,and analyzed the hoisting conditions,put forward the hoisting design calculations and engineering practices encountered actual problems and countermeasures.
