Construction method of concrete support servo system close to ultra-deep foundation pit of subway
The invention provides a construction method of a concrete support servo system of an ultra-deep foundation pit adjacent to a subway, and belongs to the technical field of building construction.The construction method of the concrete support servo system of the ultra-deep foundation pit adjacent to the subway comprises the steps that BIM models of the ultra-deep foundation pit and the surrounding environment are established for operators; according to the BIM model of the ultra-deep foundation pit and the surrounding environment, supporting design is conducted on the ultra-deep foundation pit, and construction safety is guaranteed; a support in the ultra-deep foundation pit is constructed; the servo embedded part is embedded in the reserved installation space of the servo system; hoisting the assembly box and mounting the assembly box on the servo embedded part; after the assembly box is installed, the displacement monitoring equipment is installed on the servo system; carrying out axial force loading and servo; after the axial force is loaded, the mechanical lock is manually locked; the method can solve the problems that according to an existing concrete supporting method of the ultra-deep foundation pit adjacent to the subway, the supporting axial force cannot be accurately adjusted and controlled to balance the constantly-changing water and soil pressure, and the foundation pit and the surrounding environment are difficult to protect in an all-around mode.
本发明提供了一种紧邻地铁超深基坑混凝土支撑伺服系统施工方法，属于建筑施工技术领域，该紧邻地铁超深基坑混凝土支撑伺服系统施工方法为操作人员建立超深基坑以及周围环境的BIM模型；根据超深基坑以及周围环境的BIM模型对超深基坑进行支护设计，保证施工的安全性；对超深基坑内部的支撑进行施工；将伺服预埋件预埋到预留的伺服系统的安装空间中；吊装总成箱并将其安装在伺服预埋件上；总成箱安装完成后将位移监测设备安装到伺服系统上；进行轴力加载与伺服；轴力加载完成后人工锁定机械锁；该方法能够解决现有的紧邻地铁超深基坑混凝土支撑方法无法精准调控支撑轴力以平衡不断变化的水土压力，难以全方位保护基坑及周边环境的问题。
