BIM (Building Information Modeling)-based super-high-rise super-thick mass concrete one-time pouring construction method in hot weather

Abstract

The invention discloses a BIM (Building Information Modeling)-based super high-rise super-thick mass concrete one-time pouring construction method in hot weather, and belongs to the technical field ofbuilding construction, and the method comprises the steps of establishing an engineering visualization model through a BIM technology, simulating a super-high-rise super-thick mass concrete construction process through model simulation, and optimizing a construction scheme; by optimizing the concrete mix proportion, reducing the cement consumption and increasing the fly ash mixing amount, the generated hydration heat is reduced, and the generation of temperature cracks is reduced; a chute method is adopted for one-time pouring; construction organization is optimized, continuous supply of concrete in the construction process is guaranteed, and generation of cold joints is reduced; concrete curing is conducted through a water covering method, the concrete out-of-machine temperature and theconcrete in-mold temperature are reduced, and the temperature rise in the pouring process is controlled. The method is suitable for super-thick mass concrete engineering construction of various building forms under hot conditions, the construction period can be effectively shortened, the cost is reduced, and the construction efficiency and the construction quality are improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a BIM-based one-time pouring construction method for super high-rise ultra-thick and large-volume concrete in a hot climate. Background technique [0002] At present, my country has become one of the centers for the development of super high-rise buildings in the world. As a major mainstream in the development of modern economic and social construction industry, super high-rise buildings are the symbol of economic and social development. As an important load transfer path in super high-rise buildings, foundation rafts require higher and higher strength and stiffness as the building height increases. Therefore, in the super high-rise design, the concrete volume of the foundation raft is getting larger and larger, and the strength level is getting higher and higher. The traditional large-volume concrete pouring technology for the foundation raft slab has a long cons...

AI Technical Summary

Problems solved by technology

The traditional large-volume concrete pouring technology for foundation rafts has a long construction period and complicated procedures, and it is difficult to control the construction quality under hot climate conditions

In addition, due to the large amount of pouring of large-volume concrete at one time, the construction organization is limited by various factors, and it is difficult to optimize the on-site construction
