Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a cast-in-place pile supporting structure for a broken rock structure slope in an open-pit mine. Background Art

[0002] The cast-in-place pile support structure of the fractured rock structure slope of the open-pit mine has important practical significance, mainly in improving the stability of the slope, preventing disasters, protecting the ecological environment, and improving resource utilization efficiency. It provides a strong guarantee for mine safety production and environmental protection.

[0003] After searching, a cast-in-place pile cantilever support structure with a publication number of CN218437082U is found, which includes a foundation pit body, a steel cage is arranged inside the foundation pit body, and a reinforcement device is arranged on the inner wall of the steel cage. The reinforcement device includes a circular ring block, a connecting rod and a screw, and a convenient connecting device is arranged between one side of the circular ring block and one end of the connecting rod. The inner wall of the circular ring block is symmetrically provided with threaded holes one, and the inner wall of the threaded hole one is threadedly connected with a threaded rod, and one end of the threaded rod is fixedly connected with an arc block.

[0004] However, when the above structure is poured, the buoyancy of the concrete is likely to be greater than the sum of the weight and friction of the steel cage due to the light weight of the steel cage, or the concrete has not yet set, causing the cage to float. The floating steel cage is likely to destroy the continuity of the pile body, and is prone to settlement and cracks after long-term use, affecting the service life of the cast-in-place pile support structure. Therefore, it is necessary to provide a cast-in-place pile support structure for the slope of the broken rock structure of the open-pit mine to reduce the floating of the steel cage. Utility Model Content
