50,000㎡ Changzhou Longcheng Avenue Tunnel Chooses Haobang Self-adhesive Waterproof Membrane

Project Introduction

The Longcheng Avenue Tunnel Project of Changzhou Elevated Road System starts from the main line grounding point of Tianmushan Road in Phase II of the elevated road in the east and connects to the West Elevated Road in the west, with a total length of 2253 meters. The main line of the tunnel is 1666 meters long, and the buried section is 1396 meters long. The total width of the ground road red line is 80 meters.

Main materials

Self Adhesive Waterproof Membrane

Waterproofing of underground tunnels

Traditional mining tunnels are mainly made of plastic sheets (EVA, PVC, ECB, etc.) for waterproof protection. Under the existing construction conditions and organizational forms in China, leakage is common, seriously affecting driving safety and structural life, and bringing a heavy burden to later maintenance.
Haobang's underground tunnel system solution, based on the concept of "integrated waterproofing", adopts a polymer self-adhesive film pre laid waterproofing membrane, which can effectively integrate with the subsequently poured concrete structure and prevent water from flowing between the two. In recent years, this roll material has also been used in tunnel projects and has attracted attention from multiple railway construction departments.
