Foundation pit supporting structure with tunnel on side wall of foundation pit and using method
The invention discloses a foundation pit supporting structure with a tunnel on the side wall of a foundation pit and a using method. The foundation pit supporting structure comprises a pit body. Fixing holes located above and below the tunnel are formed in the foundation pit, stand columns abutting against the side wall of the foundation pit are arranged in the mode that landing bolts are deeply embedded in the fixing holes, and a first-stage clamp and a second-stage clamp which can lock and limit a mud plate and one end of the floor are arranged through the stand columns so as to provide limiting support for the foundation pit and the tunnel soil layer. a buffer plate elastically supported by a first-stage spring is arranged, and a connecting plate elastically supported by a second-stagespring is arranged by utilizing a sleeve rod and an inner rod which are connected in a sleeving mode, so that the tunnel structure is reinforced and protected by utilizing a first-stage concrete layerand a second-stage concrete layer which are formed by pouring; and the two-stage clamp is arranged between every two adjacent stand columns, so that the floor is fixedly arranged at the upper end ofthe foundation pit, bayonets are formed in the floor, every two bayonets form a group, and limiting seats which abut against each other are arranged through the bayonets, so that the structure of thesoil layer at the upper end of the foundation pit is conveniently fixed.
本发明公开了一种基坑侧壁有隧道的基坑支护结构及使用方法，包括坑体。本发明在基坑中开设位于隧道上下方的固定孔，并利用固定孔中深入嵌装落地栓设置与基坑侧壁相抵的立柱，利用立柱设置可对泥浆板与地板一端进行锁紧限位的一级夹具与二级夹具，以对基坑及隧道土层提供限位支撑；设置由一级弹簧弹性支撑的缓冲板，并利用套设连接的套杆与内杆设置由二级弹簧弹性支撑的连接板，从而利用浇灌成型的一级混凝土层与二级混凝土层对隧道结构进行加强防护；通过在相邻两根立柱之间设置二级夹具，以便于在基坑上端固定设置地板，并通过在地板中开设两个为一组的卡口，利用卡口设置相抵的限位座，以便于在基坑上端的土层进行结构固定。
