Tunnel side wall chiseling sweeper

Abstract

The invention relates to a tunnel side wall chiseling sweeper which comprises a frame, a chiseling system, a sweeping system, a water removal system, a hopper and a power and control system. The chiseling system comprises a spray head device, a high-pressure water pump and a water storage device and is used for generating high-pressure water to chisel concrete, and the sweeping system is used forcollecting sundries and sending the sundries to the hopper; the water removal system is used for collecting sewage and sending the sewage to the hopper, the hopper is used for storing sundries and filtering the sewage and sending the filtered water to the water storage device, the power and control system provides power and controls each system, and the chiseling system, the sweeping system, the water removal system, the hopper and the power and control system are installed on the frame and move along with the frame. The mechanical chiseling construction and cleaning of side wall and base concrete can be realized.

Description

technical field [0001] The invention relates to the field of tunnel construction equipment, in particular to a chisel cleaning machine for tunnel side walls. Background technique [0002] At present, in order to ensure that the cable trench wall and the side wall concrete are firmly bonded before the trench construction in tunnel engineering, without cracks or falling off, which will affect the construction quality, the side wall concrete must be chiseled in advance to increase the bond of the concrete. force. After gouging the joint surface of the tunnel side wall, clean up the loose ballast, sundries and silt on the base of the gutter and the cable trough, and use high-pressure water to clean the joint surface of the side wall and the base after the roughing, to ensure that the base is free of water and debris thing. [0003] At present, the existing chiseling equipment for the second lining of the tunnel basically relies on the manual control of the pneumatic pick to ch...

AI Technical Summary

Problems solved by technology

[0005] When manipulating the pneumatic pick to chisel the second lining wall of the tunnel, a large amount of dust will be generated, and there is no dust collection and treatment device, which seriously endangers the health of workers

[0006] 2. Poor chisel quality

[0007] Due to the manual operation, the construction is quite random, and there are phenomena of under-cutting, under-cutting, and over-cutting, and the construction quality cannot be guaranteed.

[0008] 3. Chiseling efficiency is low

[0009] Because the machine tool is relatively heavy, and there is a strong vibration impact force during construction, it is difficult to control, it is difficult to move in the construction work space, the construction speed is slow, and the chiseling efficiency is low.

[0010] 4. High labor intensity

[0011] Due to the heavy weight of the machine and the strong vibration and impact during construction, it is easy to cause muscle fatigue in the hands of the workers, and the labor intensity of the workers is high.

[0012] 5. Poor security

[0013] The distance between the workers and the rough-cutting construction surface is relatively short, and the strong impact force generated by the machine tools will easily cause the gravel to splash on the rough-cutting surface, which poses a safety threat to the workers, and the safety is poor.

[0014] After gouging the joint surface of the side wall of the tunnel, it is necessary to clean up the loose ballast, sundries and silt on the base of the gutter and the cable trough, and use high-pressure water to clean the joint surface of the side wall and the base after the roughing, so as to ensure that the base is free of water and The sundries are basically washed manually with high-pressure water pipes, which is labor-intensive, and the accumulated water at the base cannot be cleaned effectively, which affects the bonding quality
