High-pressure water jet cutting and stripping device and using method thereof

Abstract

The invention provides a high-pressure water jet cutting and stripping device and a using method thereof. The stripping device comprises a moving carrier, a water supply assembly, an arm frame regulation and control assembly, a monitoring assembly and a control box; the arm frame regulation and control assembly comprises an arm frame telescopic rotating unit, a movable frame and a driving part, the working end of the arm frame telescopic rotating unit is connected with the movable frame, a spray head is arranged on the movable frame, and the movable frame comprises a displacement regulation and control unit; and the control box comprises a terminal controller and a displayer, the terminal controller is connected with the water supply assembly and the arm frame regulation and control assembly, and the displayer is connected with the monitoring assembly through a circuit. The using method comprises the steps that preparation work before operation is conducted, after high-pressure water jet cutting and stripping operation is finished, the arm frame telescopic rotating unit is retracted, and the moving carrier is started to move to the next working area. The tunnel lining dismantling efficiency can be greatly improved, the labor intensity of operators is reduced, the construction environment is improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a high-pressure water jet cutting and stripping device and a use method thereof. Background technique [0002] Before the tunnel is put into use, it is necessary to set a lining concrete structure layer on the inner wall surface (including the inner wall side and the inner wall top surface) of the tunnel to reinforce the tunnel and avoid falling debris from the inner wall surface of the tunnel. After the tunnel has been put into use for a long time, the lining concrete structure layer is prone to cracking. In order to ensure the safe use of the tunnel, it is necessary to partially or completely remove the cracked lining concrete structure layer and re-line it. [0003] In the demolition construction of the lining concrete structure layer, since the working position is located on the side and the top surface of the inner wall of the tunnel, and the strength ...

AI Technical Summary

Problems solved by technology

Among them, micro-blasting demolition is suitable for the demolition of a large-scale lining concrete structure layer. The vibration generated during the operation has a great impact on the surrounding lining concrete structure layer, which is not conducive to controlling the demolition depth, and is easy to damage the reinforcement inside the lining concrete structure layer. Mesh and flashing, increasing construction cost of relining

However, manual hand-held pneumatic pick removal has disadvantages such as low construction efficiency, large dust, long operation cycle, and high work intensity of operators; in addition, manual hand-held pneumatic pick removal requires climbing operations and falling concrete during operation is likely to cause damage to operators. construction safety issues

[0004] In summary, there is an urgent need for a high-pressure water jet cutting and stripping device and its use method to solve the problems of low construction efficiency, long operation period, high construction cost and poor safety in the prior art
