by Important water environment treatment project Shanghai key project domestic rare super large sewage treatment plant with the total treatment scale ranking first in Asia and the world’s top five Zhuyuan sewage treatment plant phase IV lot 1.5 project.
All precast components have been hoisted.
Since the commencement of Zhuyuan sewage treatment plant phase IV lot 1.5 project on December 30, 2020, 450000 meters of engineering piles and 510000 cubic meters of earth excavation have been completed, 230000 cubic meters of structural concrete was poured, with a cumulative output value of 940 million.
Since the large-scale precast construction was officially carried out on September 5, 2021, the hoisting of precast components has been completed by January 5, 2022, with a total of 2216 pieces and 18000 cubic meters.
Introduction of new precast structure system in Zhuyuan lot 1.5 project, the partition wall and roof of AAO reaction tank adopt integral precast structure.
Previously, in order to solve the problem of inconvenient hoisting and installation construction due to the overweight of precast components and generally 30 tons of single components in the process of project construction, the second construction group successfully developed the integral assembly system of spdw “double-sided laminated wall + inverted T-shaped laminated plate” and adopted the precast assembly construction technology connected by UHPC to make the project more efficient and economical…
