Guaranteed quality at low prices: 186-0379-3535 Ω type half-round drainage pipes, half-round pipes, Ω type drainage pipes, tunnel half-round drainage pipes Common specifications of Ω type half-round pipes include TY50mm, 80mm, 100mm, with heights of 25-40mm, 45-50mm, and 55-60mm. Ω type half-round drainage pipes, also known as half-round pipes, Ω type drainage pipes, tunnel half-round drainage pipes, etc. They are made of high-strength spring steel wire, treated with phosphoric acid for rust prevention, and wrapped with a PVC coating, then thermally bonded with geocomposite membranes to form a half-round drainage pipe. Application range of Ω type half-round pipes: Half-round drainage pipes are used in highway and railway tunnels for non-pressurized drainage, ensuring smooth drainage inside the tunnel structure and creating a non-water pressure environment around the tunnel lining, preventing leakage during the usage period. Features of Ω type half-round pipes: 1. During construction, they are buried in layers and batches, adapting to gradual deformation of the surrounding rock. 2. They prevent mud and sand from the surrounding rock from directly entering the drainage pipes and causing blockages. 3. The "smooth drainage" eliminates the influence of external water pressure, improving the stress conditions of the lining structure and reducing the occurrence of cracks. 4. Deeply buried in the tunnel lining, they effectively prevent freezing of the drainage pipes and damage to the structures in generally cold areas. 5. Due to their oriented installation, the water flow speed inside the pipes is high, with each drainage pipe generally discharging no less than 50m/h, suitable for groundwater drainage under various geological conditions.
