Prefabricated Station Component Mold

The subway prefabricated station is a kind of prefabricated building. The prefabricated components that make up the main structure of the station are produced in the factory, and then transported to the construction site for assembly. The complex main structure is constructed like building blocks. The entire assembly process of the station is carried out underground, which has higher requirements on the production and installation accuracy of prefabricated components, transportation and hoisting and other technological processes. As the flagship enterprise of prefabricated equipment in China, the related products of Qingdao Hicorp Group Heavy Industry Science & Technology Co., Ltd. have won recognition.
