高重型地连墙钢筋笼双机抬吊施工技术

Double-machine Hoisting Construction Technology of High Heavy Diaphragm Wall Steel Reinforced Cage

目前国内轨道交通车站和隧道施工大部分还是采用明挖法,基坑围护结构主要是地下连续墙支护方式。以宁波市机场快速干道永达路连接线工程I标段为实例,重点介绍了地连墙施工中高重型钢筋笼吊装的吊装参数确定、起重设备选型、吊点布置和双机抬吊过程中的施工技术控制要点。

At present, the rail traffic station and tunnel are mostly constructed by the excavation method in China. The enclosure structure of foundation pit is mainly the underground diaphragm wall for support.According to the Bid I of Ningbo Airport Expressway Yongda Road Connection Project, the article focuses introduction on the determination of hoisting parameters, selection of hoisting equipment, arrangement of hoisting points and construction technical control gist in the double-machine hoisting process of high heavy steel reinforced cage in the construction of diaphragm wall.
