Half circle drainage pipe manufacturer, spring half circle drainage pipe, spring flexible half circle drainage pipe

Description :

　　The specifications of the spring drainage hose include 50mm, 80mm, and 100mm, with heights of 25-40mm, 45-50mm, and 55-60mm. It has the characteristics of acid and alkali resistance, non permeability, etc. It is elastic and soft, and can be bent freely; Can adapt to the needs of uneven rock surfaces and various shapes of cracks; Capable of adapting to the gradual deformation of surrounding rock; Capable of withstanding the impact force of sprayed concrete without damage or deformation; It can avoid blockage caused by direct inflow of surrounding rock sediment; It can eliminate the water pressure around the tunnel and improve the stress condition of the lining structure.

　　Common specifications for Ω - shaped semi-circular tubes

　　There are TY50mm, 80mm, 100mm, with heights of 25-40mm, 45-50mm, 55-60mm

　　Application range of Ω - shaped semi-circular tube

　　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.

　　Semi-circular tube structure

　　1. PVC spring steel wire: High strength spring hard steel wire, treated with phosphoric acid rust prevention and coated with PVC.

　　2. A strong plastic coated cloth coated with PVC.

　　Our company produces semi-circular drainage pipes, also known as spring semi-circular pipes. Mainly used for high-speed railway tunnels. It has the effect of fast construction, smooth drainage, and alleviating mountain water pressure. Moreover, the materials used in the tunnel renovation project fully address the issue of outdated old tunnels lacking drainage functions
