　　The quality of the high-speed rail drainage pipe is naturally quite outstanding. It has been proven that cast iron drain pipes have outstanding performance, and their excellent noise reduction is 7.5 times that of PVC pipes, completely exceeding the general pipe materials on the market; The tensile strength of cast iron drainage pipes for bridges is generally greater than 150MPa, which is 3-4 times the strength of chemical drainage pipes such as PVC. It has good compressive strength when used for buried pipeline construction, which can prevent tree root infiltration and rodent gnawing damage.

The semi-circular cast iron drainage pipe belongs to the buried drainage pipe, which is buried in layers and batches to avoid blockage caused by the direct flow of surrounding rock mud and sand into the drainage pipe; Due to the "unobstructed drainage", water pressure is eliminated and the stress condition of the lining structure is improved. 2. Due to its deep burial inside the tunnel lining, 3. The buried cast iron drainage pipe has a high water flow velocity inside the pipe due to its rigid setting. The drainage capacity of each cast iron drainage pipe is generally not less than 50m/h, which can adapt to the discharge of groundwater under various geological conditions. 1. Lightweight and easy to handle: Cast iron drain pipes are made of lightweight materials, making them convenient for handling, loading, unloading, and construction, saving labor.

　　The bridge cast iron drainage pipe is an external steel pipe composed of high-density steel and other additives. According to different drainage requirements, the pipe hole size can be 10mm × 1mm-30mm × 3mm, and can be evenly distributed within 360 degrees, 270 degrees, 180 degrees, and 90 degrees. Widely used in drainage fields such as highways, railway foundations, subway engineering, landfills, tunnels, green belts, sports fields, and slope protection. Due to its high water content, it can also be used for underground irrigation and drainage systems in agriculture and horticulture. Widely used in drainage fields such as highways, railway foundations, subway engineering, landfills, tunnels, green belts, sports fields, and slope protection caused by high moisture content. The anti-corrosion process of bridge drainage pipes determines whether they will rust. Whether it will rust or not depends on whether the anti-corrosion process of the pipeline is done well. Qualified cast iron pipes require the use of standard thick lined cement; The outer wall of the pipeline needs to be treated with zinc spraying and coated with asphalt paint, or other epoxy resin paints can be chosen. Qualified cast iron drain pipes can be used for the above, but the main area prone to rusting is where the outer wall comes into contact with the soil due to its high humidity and oxygen content. And qualified preservatives can effectively resist rust. Although there is long-term water flow on the inner wall, oxygen is less prone to corrosion compared to the outer wall. However, if there is a cement lining, it is classified as Grade B.
