Description

Technical Field

[0001] The invention belongs to the technical field of construction machinery, and in particular relates to a large-diameter pile foundation pile head chiseling device. Background Art

[0002] Pile foundation: A deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation, referred to as a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations.

[0003] During the pouring of pile body concrete, as the bubbles or pores inside the concrete rise to the top of the pile during the vibration process, a certain range of the pile top is floating slurry, or a mixture of mud and mortar during underwater concrete pouring. In order to ensure the strength of the pile body concrete, the upper virtual pile head needs to be chiseled off. At present, large-diameter pile heads are generally chiseled off manually, which is more laborious and has high labor intensity and low efficiency for workers. Alternatively, they are chiseled off by a chiseling machine, but the disassembly and assembly of the chiseling machine is complicated and the disassembly and assembly efficiency is low. The labor burden of the workers during disassembly and assembly is heavy, and when the chiseling machine is placed on the outside of the pile head for preparation, the chiseling machine is prone to shaking, which greatly affects the operation.
