Nanchang Metro
Introduction：
Nanchang rail transit is the service of Nanchang city rail transit, the first line has been opened in December 26, 2015 passenger operation. The Nanchang subway network develops from the city center of Bayi Square in Donghu District to the east and west, with a radial layout and connecting with the surrounding area of the city.
At that time, Nanchang Metro Line 1 created a record for China's slurry shield to cross the composite terrain during the construction of the river-crossing tunnel, achieving the smallest settlement and the longest tunneling mileage in the argillaceous siltstone layer. The total length of the subway Ganjiang Tunnel is 1889 meters. It is the first tunnel of the Qianli Ganjiang River.
Both the terrain complexity and engineering quality requirements are higher than those of ordinary projects.
As a leading enterprise in China's construction waterproofing industry, experts from Hongyuan Waterproofing Group, after investigating the actual situation of Nanchang Metro, put forward the scheme of polymer coiled material as the main material of waterproof engineering, and PVC waterproof coiled material became the main material of the project.
Hongyuan polyvinyl chloride (PVC) waterproofing membrane has the characteristics of super aging resistance, flame retardant, welding construction and environmental protection. It has become an ideal product for subway projects and has been well received by all parties in the project.
