Underground continuous wall reinforcement cage hoisting method in height-limited area
The invention provides an underground continuous wall reinforcement cage hoisting method in a height-limited area, and belongs to the field of underground continuous wall construction. The undergroundcontinuous wall reinforcement cage hoisting method comprises a construction preparing process, a hoisting process, a synchronous proceeding and reinforcement cage dropping process and a reinforcementcage orifice welding process, wherein the hoisting process comprises the following steps: S31 of synchronously hoisting three hoists until the reinforcement cage is horizontally hoisted by 1.5-2.0 m,continuously and synchronously hoisting two primary hoists, and dropping a hanger by a secondary hoist; and S32 of completely straightening the reinforcement cage and relieving the hanger of the secondary hoist after weight of the reinforcement cage is borne by the two primary hoists. The underground continuous wall reinforcement cage hoisting method solves the problems that an existing hoistingway has many hoisting times, has many welding and connecting times, consumes time and labor, increases cost, is poor in reinforcement integrity, avoids phenomena such as slot wall hole collapse, cagebody mud entrainment and excessive sediments if time of mounting the reinforcement cage is too long, and slot wall exposure time is too long, and solves the problem that control on underground continuous wall construction quality is bad.
本发明提供了一种限高区域地下连续墙钢筋笼吊装方法，属于地下连续墙施工领域，其包括施工准备工序、起吊工序、同步行进和下放钢筋笼工序、钢筋笼孔口焊接工序；起吊工序包括以下步骤：S31、三台吊机同步起吊至钢筋笼水平抬起1.5至2.0m之间，两台主吊机继续同步提升，副吊机下放吊钩；S32、直至钢筋笼完全回直并且钢筋笼的重量由两台主吊机承担后，解除副吊机的吊钩；解决了现有的吊装方式吊装次数多、焊接接长次数多，耗时耗力、成本增加且钢筋笼整体性差的问题以及在安放钢筋笼时间拖长，槽壁暴露的时间过长增加，容易出现槽壁塌孔、笼体夹泥、沉渣过多等现象，对地下连续墙施工质量的控制不利的问题。
