[Zhejiang] Large volume floor concrete construction plan
Wenzhou * * * Hotel is designed as the first floor basement (partial second floor). The basement post cast strip is divided into 10 areas. Among them, Zone 1, 2, 3, 4, 8 and 9 are the basement of the first floor, and the bottom plate is 500mm thick; 5. Zone 6 and 7 are two floor basements with a floor thickness of 600mm; Zone 10 is the tower part, which is designed as the integral raft foundation of pile group cap, with the bottom plate thickness of 2500mm. The basement floor area is about 16300m2, the concrete pouring amount is about 17800m3, the concrete strength grade is C40, and the impermeability grade is S8. The bottom plate of the project is mass concrete. The key to construction is to reasonably arrange the pouring route, avoid construction cold joints, control the temperature difference between the inside and outside of the concrete, and reduce cracks.
