Application of PVC flexible membrane in tunnel engineering: key solution to improve waterproofing and durability
With the continuous development of tunnel engineering technology, waterproofing and structural protection have become the key to ensure long-term safe operation. PVC flexible membrane is gradually becoming one of the preferred materials for tunnel waterproofing projects due to its excellent anti-seepage performance, chemical corrosion resistance and convenient construction.
Technical advantages of PVC flexible membrane
Excellent waterproof performance
PVC flexible membrane has extremely low water permeability, which can effectively prevent groundwater infiltration and avoid concrete corrosion or steel corrosion caused by long-term water seepage in tunnel structure.
High flexibility and tear resistance
Adapt to the complex curved surface structure of the tunnel, not easy to break during construction, and can withstand ground settlement or slight deformation to ensure long-term sealing effect.
Chemical corrosion resistance
It can resist the common acidic and alkaline substances and microbial erosion in the tunnel environment, and is suitable for a variety of scenarios such as subways, highway tunnels, and undersea tunnels.
Convenient construction and cost optimization
Adopting hot air welding or gluing process, the joint strength is high, the construction efficiency is greatly improved, and the comprehensive maintenance cost is reduced.
Successful application cases
In recent years, PVC flexible membranes have been successfully applied to many key tunnel projects at home and abroad, such as:
A city subway tunnel: PVC flexible membrane is used as the main waterproof layer to effectively solve the problem of groundwater leakage and extend the life of the structure.
Mountain highway tunnel: Under complex geological conditions, the flexible membrane adapts to the deformation of the surrounding rock and maintains a long-term waterproof effect.
Industry prospects
As the country's requirements for infrastructure durability and environmental protection increase, the market demand for PVC flexible membranes will continue to grow. In the future, combined with intelligent monitoring technology (such as leakage sensor + waterproof layer integrated system), the application of PVC flexible membranes will be more intelligent and precise.
