The project is located in Xindu District of Xingtai City, divided into two areas, A and B, with an above-ground construction area of 91965.7 square meters, of which the above-ground construction area is 91965.7 square meters and the underground construction area is 36159.22 square meters.The project adopts steel pipe concrete bundled shear wall structure system, with fewer structural walls, flexible layout of house type and transparent space; hoisting a piece of shear wall can reach 9 meters and 3 floors, and the floor slab adopts assembled steel truss self-supporting floor slab, which can pour concrete in multiple floors at the same time, reducing the amount of concrete, eliminating the concrete vibration process and the waiting time for maintenance, and realizing the three-dimensional cross operation and the construction speed of one floor in 3 days on average.
