Abstract

The invention belongs to the technical field of construction machines and devices for CFG (cement fly-ash gravel) piles in a roadbed and roadbed reinforcement projects and particularly relates to a pile head cutting machine for CFG piles, and the machine provided by the invention is used for solving the problems that the existing cutting machine is incomplete in performances and can not meet the pile head cutting requirement of the CFG piles. The pile head cutting machine for the CFG piles comprises a control system, the control system further comprises a vertical fine adjustment control system for a cutting saw, the vertical fine adjustment control system comprises a vertical transmission lead screw, the vertical transmission lead screw, an upper screw nut which is fixed opposite to a vertical support frame and a lower screw nut which can slide relative to the vertical support frame and be fixed relative to the vertical support frame are matched and connected, and the lower screw nut is connected with an electric motor through a connecting part. By adopting the pile head cutting machine for the CFG piles, the three-dimensional cutting control in the circumferential direction, radial direction and vertical direction can be realized during the cutting process, the stable performances of the device during the cutting process can be ensured, the work efficiency of standardized operation is improved, the operation space is reduced, and the air dust pollution is reduced during the construction.

Description

technical field [0001] The invention belongs to the technical field of CFG pile construction mechanical devices in roadbed and ground reinforcement engineering, and in particular relates to a pile head cutting machine for CFG piles. Background technique [0002] In roadbed and foundation reinforcement projects, there are currently two methods for pile head cutting of CFG piles (referring to piles formed by a mixture of sand, gravel, cement, fly ash or slag). One is the manual method, that is, use a small excavator to clean the soil between the piles. After the cleaning is completed, manually use a pick or a manual saw to remove the pile head. Poor, easy to cause shallow broken piles, poor construction environment and other shortcomings. The other is the mechanical method, that is, all or part of the soil between the piles is cleaned, and after the cleaning is completed, the pile head cutting machine is used to automatically cut under the operation of personnel. This method ...
