Each set of auxiliary adjustment components 3 has a displacement component 4 installed on its bottom. The grouting repair component 2 is equipped with a detection component 5.

[0036] For example, such as Figure 2 As shown, the pretreatment component 1 includes a construction frame 101, which has an opening 105. Two sets of electric slides 102 are symmetrically installed on the bottom of the construction frame 101. One set of electric slides 102 is connected to a high-pressure blower 103 at the output end, and the other set of electric slides 102 is connected to a stretching tube 104 at the output end.

[0037] As shown in Figure 3 The grouting repair assembly 2 includes a grouting box 201, the bottom of the grouting box 201 is mounted on the top of the construction frame 101, the bottom of the grouting box 201 is communicated with a grouting pipe 203, a motor ball valve 202 is mounted between the grouting pipe 203 and the grouting box 201, and the grouting pipe 203 is slidingly connected in the opening 105.

[0038] The grouting box 201 is first filled with repair slurry, and the grouting box 201 is kept in a rotating state to avoid the problem of slurry solidification. Before subsequent grouting work, the electric sliding table 102 is started to drive the high-pressure air blower 103 to move horizontally, and the impurities in the gap are removed by high-pressure gas. Then the grouting pipe 203 is pulled to move into the crack, the motor ball valve 202 is opened, and the repair slurry in the grouting box 201 flows into the crack for repair work. When used outdoors, the first electric push rod 402 is started to drive the two sets of self-locking wheel structures 405 to descend to support the construction frame 101, and then the construction frame 101 is pushed to move. During the movement, the linkage block 404 slides in the sleeve block 403, and the compression spring is extruded at the same time. The compression spring buffers the shaking during movement, improves the buffering protection effect, and improves the stability of subsequent grouting.

The sliding block 304 is driven by the construction frame 101 to slide in the first cavity 302 and extrude the tension spring 303. The elastic force of the tension spring 303 is used to control the pushing force, so as to avoid the problem of pushing out the specified distance. After being pushed to the specified position, the electromagnetic block 305 can be started to be magnetically connected with the magnetic attraction plate 306 to perform positioning work. After the subsequent work is completed, the magnetic attraction state of the electromagnetic block 305 can be separated. The tension spring 303 starts to reset after the pressure disappears. The construction frame 101 and the auxiliary plate 301 are not located on the same vertical line by pushing the tension spring 303, which is beneficial to the subsequent placement space adjustment effect.
