Subway station deep foundation pit riding track type rapid unearthing construction method
The invention relates to an underground engineering foundation pit excavation construction method, in particular to a subway station deep foundation pit riding track type rapid excavation construction method. According to the riding track type rapid unearthed construction method for the deep foundation pit of the subway station, a riding track is reserved on the unearthed side of the foundation pit, a muck vehicle can go up and down conveniently, and the riding track is very safe after certain reinforcing and anti-skid measures are taken. The method is suitable for long and narrow deep foundation pit earthwork excavation engineering mainly taking sandy soil and cohesive soil as main materials, and the earlier-stage earth excavation speed is increased in an excavation mode combining riding tracks and steps. According to the method, an upper riding track and a lower riding track of a muck truck are reserved on the unearthed side of the foundation pit, the layered, segmented and basin-type excavation technology is combined, on the premise that the safety of the foundation pit is guaranteed, the muck truck can conveniently and rapidly move to the excavation face of the foundation pit, a construction face is created for construction of a main body structure as soon as possible, the bottom sealing time of the foundation pit is shortened, and displacement deformation of a foundation pit enclosure structure is reduced; meanwhile, the purposes of saving construction period and cost are achieved.
本发明涉及地下工程基坑挖土施工方法，具体为地铁车站深基坑马道式快速出土施工方法。地铁车站深基坑马道式快速出土施工方法，在基坑出土一侧预留马道，渣土车上下比较方便，马道做好一定的加固及防滑措施后十分安全。本方法适用于主要以砂性土、粘性土为主的狭长深基坑挖土方工程，通过结合马道及分台阶的开挖方式加速前期挖土速度。本方法在基坑出土一侧预留渣土车的上下马道，结合分层分段、盆式开挖的挖土工艺，在保证基坑安全的前提下，方便渣土车快速移动到基坑开挖面，为主体结构施工尽快创造施工面，加快基坑封底时间，减少基坑围护结构位移变形，同时达到节约工期、成本的目标。
