Overlength concrete QC achievements of construction quality control
This project is a residential community project invested and constructed by * *. The construction site is located in * * Modern Industrial Park in Anhui Province, south of the East High speed Railway Station. Resettlement housing project, including 16 single buildings, 1 kindergarten, management room and supporting public buildings (including 16 17 floor residential buildings, 1 3 floor kindergarten, 3 floor management room and 5 floor supporting public buildings), with civil air defense basement or underground garage. The total area of buildable land is 69843.288m2, and the total building area is 190000m2, including 54400m2 of underground building area. The plan size of the basement is 175m × 220m, and the length of the basement greatly exceeds the requirements of the standard joint separation. However, in order to better meet the building use function and the waterproof requirements of the basement, the basement is not set with deformation joints, only with post cast strip. The basement has high requirements for crack resistance and waterproof, and the structural concrete grade of the basement reaches C35, Reliable construction measures must be taken (sectional construction, strengthening maintenance, using additives, using cement with small shrinkage, etc.) to avoid temperature cracks in the basement floor and exterior wall without deformation joints in the basement and superstructure, which will be the key and difficult points in the construction of this project.
