Serial 丨 Establishment of waterproofing system for precast and assembled subway stations (1)

Since the adoption of precast construction at Yuanjiadian Station on Line 2 of Changchun Metro, precast stations have been widely used on Line 2, Line 6, Line 7, and Line 9 of Changchun Metro.

The construction of the South New City West Station of Changchun Metro Line 6 adopts a combination of “open cut and cast-in-place+open cut assembly+cover cut and reverse construction” to better connect the underground space of the Jucheng commercial district.

During the construction process, it is particularly important to establish a comprehensive waterproofing system due to the large number of joints in the station.
