The tallest building in Puxi丨The sky pump goes straight down, and 1262 people work! It is difficult to pour a 6-meter-thick concrete floor!

With a total construction area of more than 780,000 square meters, Xujiahui Center is one of the largest projects under construction in downtown Shanghai, and the project is expected to be completed in 2023.

The project resumed work on March 2 and officially resumed production in mid-March, and the construction of the T1 tower to 25 floors this week is expected to be capped in mid-August; The core tube of the main building T2 tower has also risen from the ground, and the podium area is expected to have zero foundation by the end of May. Sany Heavy Industry's 10 62m pump trucks participated in the construction throughout the whole process, and equipped with Sany pumping service engineers to repeatedly inspect all pump trucks to check the pressure in the car and whether there is oil leakage, and often did not close their eyes all night, which was highly recognized by the construction party.

Scientific construction and precise management

Set a record for the construction of ultra-deep foundation pits

Shanghai's "tallest building in Puxi" - the 370-meter-high T2 tower project on Hongqiao Road in Xujiahui Center,The largest and last of the main tower's concrete slabs, which are 37.2 meters deep, (6 meters thick, about 27,000 cubic meters),After 48 hours of continuous pouring in the rain, the bottom was successfully "built" at 6:30 a.m. on July 14, 2019. This marks the creation of Shanghai Construction Engineering so farA new record for pouring the deepest concrete floor for housing construction in Shanghai and the closest to the operating subway.

The total construction area is about 950,000 square meters, of which the Hongqiao Road plot consists of two super high-rise main buildings with 70 floors and 43 floors, a 15-storey hotel, a 7-storey podium and a 6-storey basement.

According to Kong Lili, executive deputy commander of the Shanghai Construction Engineering Xujiahui Center Project, on March 8, 2018, when the deepest underground foundation pit of the Shanghai construction project was excavated, there were many construction problems in front of the general contracting department of the Shanghai Construction Engineering Project.In particular, it is difficult to pour the 6-meter-thick concrete floor of the deep foundation pit of the main building.

Such a thick and large volume of concrete is poured continuously at one time to prevent the temperature stress cracks caused by the temperature difference caused by the heat of cement hydration, which has become a technical problem that needs to be overcome.
