超大地下连续墙钢筋笼吊装方案比选与优化

城市轨道交通施工环境复杂,周边构建筑物众多、人口密集、车流量较大,地下连续墙施工时钢筋笼吊装安全风险极大,方案筹划不当易引发吊装安全事故。通过地下连续墙钢筋笼吊装方案的筹划、计算,对轨道交通建设地下连续墙常用吊装方案进行总结分析和比选优化。在确保吊装安全控制的同时,达到提高施工工效和成本优化的目的,可为同类工程的施工提供借鉴和参考。

Scheme Comparison and Optimization for the Large Continuous Diaphragm Wall Reinforcement Cage Lifting

The complex environment metro construction includes the large number of surrounding buildings,dense popula-tion,heavy traffic.During the construction of continuous diaphragm wall,the steel reinforcement cage lifting is faced with enormous security risks,improper program planning is prone to lead to safety accident.By calculation and planning of the continuous diaphragm wall reinforcement cage hoisting,and scheme comparison and optimization,common scheme for rein-forcement cage hoisting is analyzed.While ensuring the safety control of hoisting,the construction efficiency and cost opti-mization are improved,and this can provide reference for similar construction.
