The control system 8 can specifically adopt a PLC controller, and the control system 8 is used to control the grinding time and speed of the air knife assembly and the water knife assembly, as well as the running speed of the running mechanism 1. Under the control of the control system 8, the water knife assembly sprays high-pressure water along the outer contour of the template to grind the template and flush and clean the impurities remaining on the template, and the air knife assembly sprays high-pressure gas along the outer contour of the template to grind the template and blow away the impurities remaining on the template.

[0027] In this embodiment, a water knife assembly and an air knife assembly are installed on the main truss 3. The water knife assembly is used to flush and clean the residual concrete, and then the air knife assembly further grinds the template and blows away the concrete blocks, water stains and other impurities remaining on the template. The grinding of the air knife and water knife is amorphous grinding, which is more adaptable to templates of various shapes, without considering the adaptability of the grinding roller and the adjustment of each grinding angle.
