Why concrete and cement pavements need waterproof base pavement shot blasting machine
As we all know, concrete cement pavement projects are most afraid of water leakage. This is because water seepage will cause the concrete to loosen, fall off, and the steel bars will rust, which will cause certain safety and quality hazards.
One of the reasons for the water seepage is that the treatment of the concrete surface layer can not completely remove the residual materials on the surface and does not retain a certain rough surface to ensure the bonding strength of the waterproof layer and the structural layer.
The shot blasting process of the waterproof base pavement shot blasting machine can clean the floating slurry and impurities on the concrete surface at one time, and at the same time, the concrete surface is roughened and uniform, which greatly improves the bonding strength of the waterproof layer and the concrete base. . Moreover, in this process, defects such as cracks in concrete can be fully exposed, so that remedial measures can be taken in advance. Therefore, under conditions, using shot blasting to treat the base surface can better ensure the waterproof effect.
The details that need to be paid attention to in the construction of the waterproof base pavement shot blasting machine are:
1) Places with serious unevenness of the structural plate should be polished or thicker polymer mortar should be used, and the strength of the mortar should meet the requirements; 2) Drain holes, pipes, yin and yang corners and other areas that cannot be cleaned by the shot blasting machine should be used When the angle grinder is cleaned, polished and trimmed smoothly, care should be taken not to produce grinding groove marks.
If a large area is constructed, the shot blasting efficiency is very high. On the construction base handed over by the general contractor, the concrete residue, bumps, oil stains, pollution, etc., are manually cleaned, which is very labor-intensive and can not be cleaned. Instead, use road shot blasting. The machine can quickly solve these problems, the construction efficiency is very high, and the labor cost is effectively saved.
