T/CECS 640-2019 “Technical Specification for Jumping Method of Ultra long and Large Volume Concrete Structures” is the only specialized association standard for seamless construction of ultra long underground concrete structures in China.
It was released in November 2019 and implemented on April 1, 2020.
It is edited by the Beijing Institute of Building Engineering and is specifically designed to address the pain points of the traditional post pouring strip construction period, multiple leakage hazards, and difficult interface treatment in the industry.
It systematically standardizes the technical requirements for the design, materials, construction, and temperature control monitoring of the jumping method for ultra long and large volume concrete structures in underground.
It is widely applicable to ultra long and large volume concrete structures such as basement floors, exterior walls, and floor slabs in industrial and civil buildings, and is the legal technical basis for eliminating post pouring strips and achieving seamless construction of structures.
