Subway section contact passage TRD reinforcing construction method
The invention discloses a TRD reinforcing construction method for a metro section connecting channel. The TRD reinforcing construction method comprises the steps of surveying and setting out, digging a groove, hoisting an embedded box, placing a pile machine in place, connecting a cutting box with a host machine, installing an inclinometer, forming a wall through a TRD construction method, treating replacement soil and pulling out the cutting box. The device has the beneficial effects that the chain saw type tool box is vertically inserted into the stratum and then horizontally and transversely moves, meanwhile, the tool is driven by joint debugging to rotate up and down, original soil is stirred and mixed, cement paste is poured, a cement wall with a certain thickness is formed, all soil layers in the vertical direction are mixed and stirred at the same time, and the construction efficiency is improved. A high-quality wall with uniform full-layer strength and waterstop performance can be obtained; the cutting box continuously and transversely stirs and mixes, a formed wall is continuous, the surface is smooth, the thickness is consistent, the wall body uniformity is good, no connector exists, hydraulic pressure is adopted as power, stability and forcefulness are achieved, the formed wall body is high in vertical precision, the inclination degree of the cutting box can be monitored at any time through a multi-layer inclinometer arranged in the cutting box body, and construction of an inclined continuous wall can also be conducted.
本发明公开了一种地铁区间联络通道TRD加固施工工法，包括测量放样、开挖沟槽、吊放预埋箱、桩机就位、切割箱与主机连接、安装测斜仪、TRD工法成墙、置换土处理并拔出切割箱。本发明的有益效果是：利用链锯式刀具箱竖向直插入地层中，然后做水平横向运动，同时由联调带动刀具作上下回转运动，搅拌混合原土并灌入水泥浆，形成一定厚度的水泥墙，对垂直方向所有土层同时进行混合搅拌，可得到全层强度、止水性能均匀的高品质墙；切割箱连续横向搅拌混合，成墙连续、表面平整、厚度一致、墙体均匀性好，无接口，采用液压作为动力，更稳定强劲，成墙墙体垂直精度高，切割箱体内配置的多层倾斜计可随时监视切割箱的倾斜度，也可进行倾斜式连续墙的施工。
