Discussion On Prefabricated Assembly Plan Of Subway Underground Station

Abstract

Prefabricated assembly technology has become an important direction for the development of subway underground stations. Comprehensively considering the three factors of stress, waterproof and construction environment, this paper proposes a set of prefabricated and cast-in-place assembly plans for subway stations. On the premise of ensuring that the overall stress form of subway station frame does not change significantly, the detailed prefabricated joint structure is designed, which effectively solves the waterproof problem of underground structure. The combination of permanent column and temporary column is realized, the investment of formwork support is reduced, and the assembly construction process of subway station is greatly simplified.
