Zhengzhou Bridge Cast Iron Drain Pipe Specification and Size Support Customization

Description :

　　Common materials for drainage pipes include cast iron pipes, PVC pipes, etc. Common cross-sectional forms of drainage pipes include circular, square, etc. Bridge drainage pipes, due to their unique cast iron technology, are not easy to rust, maintenance free, and not easily deformed at high and low temperatures, with a long service life; It has been commonly used in various bridges; According to different materials, it can be divided into two types: cast iron drain pipes and PVC drain pipes; PVC drainage pipes have low strength and are prone to deformation Very poor weather resistance Short service life High maintenance costs; Gradually replaced by cast iron drain pipes; Bridge drainage pipes can be divided into two types based on their external dimensions: circular drainage pipes and rectangular drainage pipes; The commonly used ones are a total height of 420mm, a large mouth inner diameter of 215mm, a small mouth inner diameter of 100mm, and wall thicknesses of 5.5mm.7mm.8mm.10mm The common specifications for rectangles include 125 × 400mm, 160 × 447mm, 125 × 300mm, 125 × 510mm, 125 × 600mm, 160 × 585mm, etc. Generally, circular shapes can be ordered and shipped on the same day!

　　The bridge deck water flows into the drainage hole through the inlet holes located on the side of the curb or sidewalk components, and corresponding water collection tanks are set up around the three edges of the drainage hole to collect, guide, and intercept water. To prevent large pieces of garbage from entering and blocking the drainage channel, a cast iron grille cover (1) is installed at the inlet of the water inlet. The cast iron drainage pipe has a longitudinal drainage hole and a circular drainage pipe. The diagram shows a relatively complete cast iron drainage pipe, which is suitable for paving structures with waterproof layers for longitudinal drainage.

　　During the construction process, the key construction project of the external backbone road network in Xiong'an New Area took the pilot work of building a strong transportation country as an opportunity to strengthen the promotion and application of mature and advanced technologies, encourage technologies such as "four new" and "three micro improvements", strengthen technological innovation, promote intelligent construction, and help improve quality. In collaboration with research institutions, accelerate the promotion of three major research topics: smart highways, durable pavements, and intelligent construction. Focusing on the requirements of new infrastructure, with the help of technologies such as 5G and Beidou high-precision positioning, we plan to build a digital intelligent transportation infrastructure, reserve conditions for autonomous driving technology, and create a quasi all-weather intelligent control channel. Pay attention to long-life road surfaces and accelerate the research on complete technology for road materials, design, and construction.Cast iron drainage pipes are commonly used in bridge systems, longitudinal and transverse drainage of highways, and permeable areas. In addition to their advantages such as impact resistance, high strength, high mechanical properties, good toughness, and strong bending resistance, they have a beautiful and elegant appearance, smooth inner walls, and low friction coefficient; It generally consists of three parts: cast iron drain pipe, iron grate, and steel sleeve. Compared with PVC bridge drain pipe, it has outstanding advantages, non-toxic, tasteless, anti-corrosion, anti-aging and good weather resistance; The service life can last up to 50 years. The production process of cast iron drain pipe and cast iron guardrail bracket is identical; Composed of high-density steel with the addition of other additives to form an external steel pipe;
