Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and particularly relates to a leakage prevention and plugging device for building construction. Background Art

[0002] During the building construction process, wall cracks often occur. The generation of cracks will affect the strength of the building structure. Therefore, it is necessary to fill the cracks by grouting, injecting solidifying materials such as concrete, lime or other chemical materials to fill the cracks and pores in the wall.

[0003] An existing Chinese invention patent (CN114635583B) discloses a leakage prevention and plugging device for building construction. First, the device is moved above the crack, and the grouting material is manually fed into the feeding box. The heights of the installation column and the grinding strip are adjusted manually until the bottom end of the installation column reaches the bottom end of the crack. Then, the adjusting screw is rotated manually until the outer end face of the grinding strip fits the inner wall of the crack. The first grinding motor drives the first installation shaft, the installation column, the grinding strip and the second installation shaft to rotate synchronously. The grinding strip in the high-speed rotation state grinds the inner wall of the crack. The U-shaped frame is manually pushed along the crack, and the grinding mechanism continuously grinds the inner wall of the crack. The grouting material is fed into the ground crack through the feeding mechanism, and the grouting material in the crack is vibrated by the ramming mechanism.

[0004] In the crack plugging treatment, it is necessary to trim the crack, grind and clean the irregular parts of the crack, so as to facilitate subsequent grouting. Although the above method can grind the crack through the grinding strip, the width of the crack is different, and the grinding diameter of the grinding strip cannot be changed. Therefore, when trimming a crack smaller than the diameter of the grinding strip, the crack will be over-ground, increasing the crack width, affecting the strength of the wall, and increasing the difficulty of subsequent crack grouting. Moreover, the above method cannot trim the vertical wall and roof cracks, and the application range is small. Summary of the Invention

After the stop block 706 extends out of the fixed shaft body 102, the spring five 710 pushes the stop block 706 out of the slide groove four 709, thereby causing the stop block 706 to get stuck on the side wall of the fixed shaft body 102, preventing the spring three 705 from pushing the L-shaped slider 703 into the fixed shaft body 102.
