Abstract

The invention belongs to the technical field of rail traffic engineering, and particularly relates to an alpine region metro station heat insulation structure. The alpine region metro station heat insulation structure comprises an underground continuous wall, a waterproof layer, an external heat insulation layer, an internal heat insulating coating layer, a station main slide wall, a station maintop plate, a station main bottom plate, a backfill soil layer and a temperature control system. According to the alpine region metro station heat insulation structure, aluminum silicate heat insulation coating serves as the internal heat insulation coating layer, so that the alpine region metro station heat insulation structure is good in water resistance, high in cold resistance, good in crack and earthquake resistance and low in shrinkage factor.

Description

technical field [0001] The invention relates to the technical field of rail transit engineering, in particular to a thermal insulation structure of a subway station in an alpine region. Background technique [0002] Since the 21st century, my country has ushered in an unprecedented upsurge in the construction of subways. As of the beginning of 2017, there are 31 cities in mainland China that have opened and operated rail transit, with a total mileage of about 4142km. Due to the vast territory of our country, the cities operating subways are distributed from east to west, from south to north, coupled with seasonal changes in various regions, resulting in considerable temperature differences in the operation of subways. [0003] For the Northeast region, due to the low temperature in winter, the structure of the subway station freezes and swells, resulting in poor durability, which affects the operation of the subway. According to the data, the lower the temperature, the thic...
