[Anhui] Construction Scheme for Tower Crane Foundation of East Plot of Greenland Central Plaza
The project is divided into transport management center, commerce and passenger station, covering an area of about 35000 square meters, with a total construction area of about 150000 square meters. Two floors underground and 3-7 floors above ground. The thickness of foundation raft is 600mm, and column piers are set under independent columns. According to the actual construction progress on site, the site is ready to install 6 # tower crane, which is located between 1/N-1/P axis and 36-37 axis. The model of tower crane is QTZ80, the independent height is 40 meters, the operating radius of the tower crane's boom is 56 meters, and the maximum rated lifting capacity is 60 KN; The maximum lifting height is 140m. According to the data provided in the QTZ80 Tower Crane Operation Manual provided by Shandong Dahan Construction Machinery Co., Ltd. and the technical parameters such as the foundation bearing capacity of the soil layer where the tower crane is located, the tower crane foundation is designed to be a reinforced concrete structure cushion cap foundation, and the design size is 5m × 5m × 1.35m (length × width × height). During the use of the tower crane, there shall be no ponding within the foundation range. Reinforcement: upper reinforcement: vertical and horizontal HRB40020@170 ； Lower layer reinforcement: vertical and horizontal HRB40020@170 。 The concrete grade of tower crane foundation is C35.
