It could be that you just do what is prescribed. >>>More
1) base treatment, first the embedded nozzle periphery is not dense concrete carefully chiseled off, the thickness of chiseling is about one-third of the plate thickness, when chiseling the caisson concrete floor slab to be inclined plane chiseling, careful construction, can not destroy the concrete floor slab that most of the pit is retained below, then rinse the chiseled part with clean water, and the base cleaning must ensure that it is clean, no debris such as broken concrete; >>>More
