Construction method and cutting devices for underground diaphragm wall at tunnel portal of subway station
The invention discloses a construction method of an underground diaphragm wall at a tunnel portal of a subway station. The method includes the following steps that multiple saw penetrating pipes are arranged in the range corresponding to the position of the reserved tunnel portal of the subway station on a steel reinforcement cage of the underground diaphragm wall in the direction perpendicular to the wall surface of the underground diaphragm wall, after the underground diaphragm wall is completely poured, when a main structure of the subway station is constructed, embedded pipes are arranged in the positions, located on the two sides and at the bottom of the tunnel portal of the subway station, of the outer portion of the side walls of the subway station, the two ends of each embedded pipe are sealed, in the detaching process, wire saws penetrate into the saw penetrating pipes, cutting devices are controlled to cut a wall body into blocks, the concrete blocks are lifted away, and therefore detaching work is finished. The saw penetrating pipes are arranged in advance, plugs of the pipes are directly removed, the wire saws penetrate into the pipes for cutting operation, so that time spent on the process is saved, the structure of the position of the tunnel portal of the subway station is prevented from being damaged, the process can be synchronously carried out with other construction processes, the construction period is shortened, energy is saved, and the environment is protected. The cutting devices are good in adjustability, capable of meeting the requirements of various environments, two groups of the cutting devices can synchronously or alternately conduct cutting operation, and construction efficiency and controllability are improved.
本发明公开了一种地铁车站洞门处地下连续墙施工方法，在地下连续墙钢筋笼上与车站预留洞门位置对应的范围，沿垂直于地下连续墙的墙面方向设置若干穿锯管，在地下连续墙浇筑完成后，在车站主体结构施工时，车站侧墙外部位于车站洞门两侧和底部的位置设置预埋管，并对预埋管的两端进行封堵，在拆除时，从穿锯管孔内穿入绳锯，操控切割装置进行墙体分块切割，将砼块吊走，完成拆除工作；本发明通过预设管路，直接打开管路封堵，穿入绳锯进行切割，节省工序时间，避免对车站洞门位置结构造成破坏，可以与其他施工工序同步进行，缩短工期，节能环保，切割装置可调性好，适应多种环境需求，可以两组同步或者交替进行切割，提升施工效率和可控性。
