Abstract: Based on the Phase Ⅱ cold storage construction project of Cold Chain Logistics Center of Yinli Agricultural Products, this study focuses on the constructive aspects of modern super-large high-rise cold storages including the high-efficiency space design, construction technology of prestressed structure, the early shrinkage of concrete to prevent cracks during the construction process, the prestress loss test at low temperatures, the large-scale prestressed cold storage insulation and the steam insulation control. A complete set of modern super large-scale high-rise cold storage construction technology has been formed, which integrates the key technology of long-span prestressed cold storage structure design and construction, the external thermal insulation system technology of super large cold storage exterior wall, and the structural intelligent health monitoring technology.

Keywords: high-rise cold storage; prestressing; external insulation; construction
