The control structure 4 is arranged on the main structure 1, and can control the movement of the main structure 1, the movement of the mounting seat 31, and the rotation and start and stop of the nozzle 32, so as to realize intelligent operation, so as to complete the demolition efficiently and quickly. In addition, the device is small in size and occupies little space. It can be used in narrow construction sites to ensure that the normal road traffic is not affected during the renewal construction of the viaduct crash barrier.

In addition, the linear drive mechanism 21 is a hydraulic rod, which has the advantages of light weight, small size, and fast response speed.

[0056] In actual applications, there is a height difference between the driving lane on the viaduct road surface and the bottom surface of the crash wall, and the height of the driving lane is greater than the height of the bottom surface of the crash wall.

[0060] Furthermore, the equipment also includes a background (not shown in the figure), which includes a high-pressure pump station part and a power part. The high-pressure pump station is connected to the nozzle 32 through a high-pressure water pipe to deliver high-pressure water to the nozzle 32; the power part is connected to the control structure 4 through a cable to provide power for the operation of the equipment, thereby ensuring the smooth progress of the demolition operation.
