Problems solved by technology

Especially at night when the basement shear wall lacks water, it is difficult to achieve manual operation
According to previous construction experience, the effect of traditional artificial watering maintenance is not very good. Most of them do not keep the basement shear wall in a wet state during the maintenance period according to the specifications, and it is easy to appear shrinkage cracks on the concrete surface, resulting in concrete. The quality does not meet the design requirements
