　　Specification of spring drainage semi-circular pipe:

　　Common specifications for Ω - shaped semi-circular tubes;

　　The application range of Ω - shaped semi-circular tubes;

　　 Half circle drainage pipes are used for pressure free waterproofing in highways and railway tunnels, ensuring smooth drainage inside the tunnel structure and creating an environment without water pressure around the tunnel lining structure, ensuring that the tunnel does not leak water during its service life.

　　Characteristics of Ω - shaped semi-circular tube;

　　 1. During construction, it is a concealed drainage pipe that is buried in layers and batches, and has the characteristic of adapting to the gradual deformation of the surrounding rock;

　　 2. Avoid direct flow of surrounding rock mud and sand into the drainage pipe, which may cause blockage;

　　 3. Due to the smooth drainage, the external water pressure is eliminated, the stress condition of the lining structure is improved, and the occurrence of cracks is reduced;

　　 4. Due to its deep burial inside the tunnel lining, it can effectively prevent freezing inside the drainage pipe and damage to the structure caused by frost heave in generally cold regions;

　　 5. Due to its rigid orientation, the buried drainage pipe has a high water flow velocity inside the pipe, and each drainage pipe generally has a drainage capacity of not less than 50m/h, which can adapt to the discharge of groundwater under various geological conditions.
