Since the beginning of summer

, many cities in the south have suffered extreme rainfall, and urban waterlogging has once again become a pain point for people's livelihood. Under the background of the "14th Five-Year Plan" clearly "promoting the construction of sponge cities", building an efficient rainwater collection pipe network has become a key part of solving the problem of "looking at the sea" in cities. At this time, AD PE coil pipe is becoming a "right-hand man" for the construction of rainwater collection pipe network by virtue of its performance advantages adapted to the needs of sponge cities.

The core of sponge city is "seepage, stagnation, storage, purification, use, and drainage". As a connecting carrier of "storage" and "drainage", rainwater collection pipe network needs to take into account corrosion resistance, sealing and construction efficiency. Traditional concrete pipes or cast iron pipes are often corroded and leaked due to long-term contact with rainwater and sediment, and need to be transported in sections and a large number of joints, which not only has a long construction period, but also easily becomes a "short board" for rainwater collection systems. The use of high-density polyethylene (HDPE) raw materials for AD PE coils solves these problems from the root cause - the material itself is resistant to acid and alkali, impact resistance, and even if buried in the ground for decades, it will not crack due to soil corrosion or external extrusion; the smooth inner wall can reduce water flow resistance, improve rainwater transmission efficiency, and even reduce the risk of pipe network blockage.

Construction convenience is another major advantage of AD PE coils. Unlike the "segment" transportation of traditional pipes, PE coils can be rolled into a cylindrical overall transportation, which not only saves transportation space, but also greatly reduces the amount of earthwork excavation on site. In the sponge city renovation of a newly built community, the construction team completed the laying of a 1.2-kilometer rainwater collection pipe network in just 3 days - the coil was pulled directly into the pre-dug trench through the "towing method", without splicing in sections. The number of joints is reduced by 80% compared with traditional pipes, effectively reducing the hidden danger of leakage. The person in charge of the property in the community said: "In the past, it took half a month to lay concrete pipes. Now with AD PE coils, it is fast and stable. During the trial operation in the rainy season, the rainwater collection rate was 25% higher than expected."

In addition to its material and construction advantages, the "adaptability" of AD PE coils also fits the diverse needs of sponge cities. Whether it is the "shallow buried" pipe network under the road green belt, the "ecological" collection system next to the park lake, or the "roof rainwater recovery" pipe network of the commercial complex, the corresponding specifications can be found - the pipe diameter coverage from DN200 to DN800 can meet the rainwater flow requirements of different scenarios. More importantly, AD Pipeline always puts quality first: each batch of PE coils is produced in accordance with GB/T 13663-2018 national standards, and has undergone more than 10 tests such as stress testing and tensile testing before leaving the factory to ensure stable product performance; for projects with complex terrain, a technical team will also be provided for on-site guidance, and follow up from pipe network design to construction and commissioning, so that customers can "use it with confidence".

With the construction of sponge cities shifting from "pilot" to "comprehensive promotion", the demand for rainwater collection pipe networks is growing at a rate of 20% per year. With its core advantages of "corrosion resistance, high efficiency and convenience", AD PE coils not only help cities solve waterlogging pain points, but also promote rainwater resources from "draining" to "utilization" - for example, the rainwater collection system built with PE coils in a city park can recycle about 5,000 cubic meters of rainwater every year for irrigation and greening and replenishing landscape water, which not only saves tap water consumption, but also reduces municipal drainage pressure.

From "waterlogging every time it rains" to "sponge water absorption", the ecological transformation of cities requires precise efforts in every link. As a brand in the plastic pipe industry, AD Pipes has always focused on the construction needs of sponge cities, and provides "reliable options" for the construction of rainwater collection pipe networks by optimizing the performance of PE coils and simplifying the construction process. In the future, as more cities join the ranks of sponge city construction, AD PE coil will continue to play its advantages and inject more kinetic energy into the construction of "breathing city".
