Description

Technical Field

[0001] The utility model relates to the technical field of cast-in-place piles, in particular to a pipe-sunken type artificial hole-digging cast-in-place pile construction device in a poor foundation. Background Art

[0002] Sunken-tube cast-in-place piles are one of the many types of pile foundations used in civil engineering. They utilize a steel pipe that matches the designed dimensions. After the pile tip is inserted into the soil, a steel reinforcement is placed within the casing. The pipe is then pulled out by vibration or hammering while concrete is poured. The vibration from pulling out the pipe compacts the concrete, forming the desired cast-in-place pile. This construction method is suitable for locations with groundwater, quicksand, or silt.

[0003] After searching, a Chinese patent with patent publication number CN215105266U discloses an internal-driven pipe-driven cast-in-place pile device, which includes a base and a cylindrical seat. A lifting mechanism is fixedly installed on the upper end of the base, and a vibrating pile hammer is fixedly installed on the top of the cylindrical seat. The top of the vibrating pile hammer is connected to the lifting mechanism. After use, a large amount of soil will adhere to the surface of the pipe-driven cast-in-place pile. In this application, the pile pipe and the baffle are fixedly connected, which is inconvenient to disassemble for cleaning and easily affects the next use. At the same time, relying solely on the vibrating pile hammer to drive the pile pipe to compact the concrete is inefficient and inconvenient to use. Utility Model Content
