Abstract

The invention relates to the technical field of landslide construction, in particular to an anti-landslide device for a deep foundation pit and a using method of the anti-landslide device. The anti-landslide device is applied to fix a slope, the slope comprises an inclined plane, threaded deep holes are vertically formed in the inclined plane at equal intervals, and a channel is formed in the bottom end of the slope. The anti-landslide device comprises a base, a vibration absorption fastener and a covering plate, wherein the base is coaxially arranged in the channel; the vibration absorption fastener comprises fixing heads, fastening steel rods, concrete threaded columns, yielding buffer parts and fixing abutting parts, the fixing heads are arranged in the threaded deep holes, and in the working state, the concrete threaded columns are formed by pouring concrete into the threaded deep holes; the fixing abutting parts are coaxially arranged at outlets of the threaded deep holes, and theouter ends of the concrete threaded columns abut against the other abutting ends of the fixing abutting parts; and the covering plate is arranged on the slope face, the fastening steel rods penetratethrough the covering plate to be elastically connected with the covering plate through the fixing abutting parts in a fastened mode, and the bottom end of the covering plate abuts against the top endof the base. The device is stable in structure, sliding of landslide soil can be effectively prevented, and vibration force can be eliminated.

Description

technical field [0001] The invention relates to the technical field of landslide construction, in particular to an anti-landslide device for deep foundation pits and an application method thereof. Background technique [0002] Deep foundation pit refers to a project where the excavation depth exceeds 5 meters (including 5 meters), or the depth does not exceed 5 meters, but the geological conditions, surrounding environment and underground pipelines are particularly complicated. Foundation pit engineering mainly includes the design and construction of foundation pit support system and earthwork excavation, which is a highly comprehensive system engineering. It requires close collaboration between geotechnical and structural engineering technicians. The foundation pit support system is a temporary structure and is no longer needed after the completion of the underground construction. Both the foundation pit and the foundation trench are used to build the foundation of the bu...
