HDPE double-wall corrugated pipe helps to build a sponge city

2025-08-18

With the continuous acceleration of urbanization process, urban waterlogging, water shortage and other issues have become increasingly prominent, and the concept of "sponge city" construction has come into being. Sponge city emphasizes that cities are like sponges, and have good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, water is absorbed, stored, seeped, and purified, and when necessary, the stored water is "released" and used. In this system project, the drainage pipe network is an important infrastructure, and its quality and performance directly affect the effectiveness of sponge city construction. With its excellent performance, HDPE double-wall corrugated pipes have become an ideal pipe material to help sponge city construction.

AD HDPE double-wall corrugated pipe is made of high-density polyethylene (HDPE) material, which has significant advantages such as light weight, high strength, corrosion resistance, smooth inner wall, and large drainage flow. Its unique double-wall structure, that is, the smooth and flat inner wall and the corrugated design of the outer wall, not only improves the ring stiffness and impact resistance of the pipe, ensures stable operation in complex underground environments, effectively withstands soil pressure and ground loads, but also reduces water flow resistance, improves drainage efficiency, and perfectly meets the requirements of sponge cities for rapid collection and smooth discharge of rainwater.

AD HDPE double-wall corrugated pipes can play an important role in rainwater infiltration, stagnation, purification and discharge in the construction of sponge cities. In the rainwater collection system, it can efficiently collect surface runoff and introduce rainwater into the reservoir or infiltration facilities; in the discharge system, its excellent flow characteristics can quickly discharge excess rainwater and reduce the pressure of urban waterlogging. At the same time, HDPE material has good chemical stability and aging resistance, is not easy to be corroded by chemicals in the soil, and the service life can reach more than 50 years, which greatly reduces the later maintenance cost and provides a solid guarantee for the long-term stable operation of sponge city.

In addition, the environmental protection characteristics of AD HDPE double-wall corrugated pipes are also highly compatible with the sustainable development concept of sponge city. No toxic and harmful substances are released during the production process of pipes, and the materials can be recycled, which meets the requirements of green building. Its flexible connection method is not only convenient to install, can adapt to the slight settlement of the foundation, but also can effectively prevent leakage, avoid pollution to groundwater, and protect the urban water environment.

In practical applications, AD HDPE double-wall corrugated pipe has been widely used in the rain pipe network project of various sponge city construction projects such as urban main roads, park green spaces, and residential quarters. Whether it is used for drainage of rain gardens, overflow of concave green spaces, or water system connection of urban ecological corridors, it has shown excellent comprehensive performance and contributed an important force to the construction of a sponge city system that combines "seepage, stagnation, storage, purification, use, and drainage".

As a leading enterprise in the plastic pipe industry, AD Pipeline has always been committed to providing high-quality pipe products for urban construction. With its excellent performance and reliable quality, HDPE double-wall corrugated pipes will continue to empower the construction of sponge cities and help create more livable, resilient and sustainable modern cities.
