Tunnel waterproofing membrane is a material used in tunnel waterproofing engineering, and its main functions include the following aspects:
1. Waterproofing: Tunnel waterproof film can effectively prevent the interior of the tunnel from being eroded and soaked by groundwater, rainwater, or other liquid substances, thereby improving the service life and safety performance of the tunnel.
2. Corrosion prevention: The tunnel waterproof film has the characteristics of acid alkali resistance and corrosion resistance, which can work in harsh environments and prevent the bottom soil material from corroding the tunnel structure mainly made of iron and steel.
3. Thermal insulation: The tunnel waterproof film has good thermal insulation effect, which can stabilize the temperature, make the climate inside the tunnel more pleasant, and reduce the cost of air conditioning inside the tunnel.
4. Shock absorption and buffering: The tunnel waterproof membrane material has extremely strong toughness and can serve as a cushion in the event of natural disasters such as earthquakes, reducing damage and displacement caused by vibration.
In short, tunnel waterproofing membranes play a very important role in modern urban underground transportation and construction engineering, ensuring the normal operation and use of tunnels by providing necessary functions such as waterproofing, insulation, shock absorption and buffering.
