L-shaped half cover excavation construction method suitable for crossroad subway station
The invention discloses an L-shaped half cover excavation construction method suitable for a crossroad metro station, which comprises an excavation construction process and a dismantling construction process, in the excavation construction process, an open excavation area is constructed on one side of the metro station close to a main trunk road of the crossroad by adopting an open excavation method, and a cover excavation area is constructed on one side of a secondary trunk road by adopting a cover excavation method; the open excavation area and the cover excavation area are alternately excavated layer by layer, the dismantling construction process is alternately dismantled layer by layer, and finally the L-shaped foundation pit is formed; according to the method, open excavation construction convenience and cover excavation ground influence reduction are ingeniously combined, vertical access of muck, equipment and personnel is facilitated, open excavation operation and underground excavation operation do not affect each other, the foundation pit construction efficiency is improved, and meanwhile the influence on road traffic is reduced; the L-shaped foundation pit is attached to the crossroad, the occupied area is small, and the pavement distribution can be flexibly adjusted; the method has extremely high economical efficiency, scientificity and replicability, and has good guiding significance for construction of the subway station at the crossroad.
本发明公开了一种适用于十字路口地铁车站的L形半盖挖施工方法，包括开挖施工过程和拆除施工过程，开挖施工过程采用在地铁车站靠近十字路口主干道一侧采用明挖法施作明挖区，并在次干道一侧采用盖挖法施作盖挖区，明挖区与盖挖区逐层交替开挖，拆除施工过程逐层交替拆除，最终形成L形基坑；本方法将明挖的施工方便与盖挖的减少地面影响形成了巧妙结合，有利于渣土、设备及人员的上下进出，明挖和暗挖作业互不影响，提升了基坑施工的效率，同时还减少了对于路面交通的影响；L形基坑贴附在十字路口设计，占地面积小并能够灵活调整路面分布；本方法具有极高的经济性、科学性及复刻性，对十字路口地铁车站的施工具有良好的指导意义。
