The invention relates to a foundation pit support back shore device for pipe gallery construction. The foundation pit support back shore device comprises a base, a motor and an inner thread pipe. A supporting column is fixed to the top of the base. An installing groove is formed in the bottom face of the supporting column. The inner thread pipe is installed in the installing groove in a rotating manner. A supporting pipe is arranged on the periphery face of the supporting column in a sliding manner. A back shore platform is fixed to the top of the supporting pipe. A round groove is formed in the bottom face of the back shore platform. A lead screw is installed in the round groove in a rotating manner. Two first sliding grooves are formed in the top of the back shore platform. Two second sliding grooves are formed in the bottoms of the two first sliding grooves. Limiting parts are arranged in the two second sliding grooves in a sliding manner correspondingly. Two strip-shaped insertinggrooves are formed in the periphery face of the lead screw. An abutting-against part is arranged in each first sliding groove in a sliding manner. The foundation pit support back shore device has theeffect that the back shore platform stop moving after making contact with the top face of a tunnel.
本申请涉及一种用于管廊施工的基坑支护顶撑装置，其包括底座、电机以及内螺纹管；底座顶部固定有支撑柱，支撑柱底面开设有安装槽，内螺纹管转动安装于安装槽内；支撑柱外周面滑移设置有支撑管，支撑管顶部固定有顶撑平台；顶撑平台底面开设有圆形槽，圆形槽内转动安装有丝杠；顶撑平台顶部开设有两个第一滑槽，两个第一滑槽底部开设有两个第二滑槽；两个第二滑槽内分别滑移设置有限位件；丝杠外周面开设有两个条形插槽；每个第一滑槽内均滑移设置有抵接件。本申请具有便于顶撑平台与隧道顶面接触后停止移动的效果。
