The operation space, therefore, the earthwork has a large amount of excavation and the backfilling amount is also large. Since all work is done on site, all wall panels and roof panels are equipped with formwork, and the formwork must be removed after the concrete has reached full strength. Therefore, the formwork and scaffolding are in great demand, the construction period is long, the labor is large, and all raw materials are It is transported to the site in bulk form, polluting the environment, causing waste of raw materials, high labor costs, and the manual vibration of concrete on-site pouring is difficult and demanding. If it is slightly vibrating, it will leave hidden water leakage. In addition, the quality of cast-in-place concrete is uncontrollable, the curing conditions are poor, and the possibility of micro-cracks in concrete is large. In the later stage, rainwater will leak through micro-cracks, which will affect the building quality.
