Every rainstorm season, the scene of "looking at the sea" in the city always triggers a heated debate. In fact, the "sub-health" of the drainage system is often hidden underground: pipe blockage, inspection well leakage, road surface settlement... The root cause of these problems is that the pipeline and the inspection well are not matched. In traditional drainage projects, the pipeline and inspection well often come from different suppliers, the interface size is deviated, and the sealing process is inconsistent. It is like "two building blocks that cannot be put together tightly". In a few years, there will be leakage and disconnection, which will lay hidden dangers for urban drainage.

In response to this industry pain point, AD Pipeline provides a "system-level" solution - inspection wells are equipped with HDPE carat pipes, so that the drainage system can be changed from "fragmented splicing" to "integrated coordination".

First talk about the "hard power" of HDPE carat pipe itself: As one of the main products of AD pipeline, it uses high-density polyethylene raw materials and is made by winding the structural wall process. The pipe wall is a unique "corrugated + hollow" structure, which is not only light in weight and easy to install, but also has super ring stiffness (up to SN16), which can easily cope with the heavy load pressure and soil settlement of municipal roads. More importantly, HDPE material is inherently resistant to corrosion. Whether it is acidic sewage or alkaline soil, it can "resist" decades without aging, and is more durable than traditional cement pipes or steel pipes.

But the light pipe is not good enough. Interface matching is the key. AD's inspection wells are specially designed with "customized interfaces" for HDPE carat pipes - such as socket connection structure. When the pipe is inserted into the inspection well, the sealing rubber ring at the interface can perfectly fit the corrugated lines of the carat pipe, like "the sealing ring wraps the straw", and the leakage point is completely blocked. Moreover, all sizes strictly follow national standards. Pipes from DN300 to DN1200 have corresponding inspection well models, and there is no need for on-site "cutting adjustment", and the installation efficiency is increased by more than 30%.

When the inspection well and the HDPE carat pipe are "seamlessly connected", the performance of the entire drainage system will take a "qualitative leap":

First, completely solve the leakage problem - the sealing rubber ring at the interface plus the smooth inner wall of the carat pipe itself, the sewage will never "run" out of the gap, avoiding soil pollution and groundwater level decline;

Second, the anti-settlement capacity is doubled - the corrugated structure of the carat pipe can disperse soil pressure, and the thickened well wall of the inspection well can withstand heavy ground loads. The two work together, even if the road surface has slight settlement, the pipeline will not be disjointed;

Third, the maintenance cost has dropped sharply - the HDPE material does not scale or rust, and the inner wall of the inspection well has also been smoothed. Even if there is debris blockage, it can be passed by flushing it with high-pressure water, which is better than that of cement inspection wells. " "Excavation type" is too convenient to maintain;

Fourth, the lifespan is extended by 20 years - the whole system is made of plastic, there is no problem of steel corrosion or cement cracking, and the design lifespan can reach 50 years, almost the same as the building.

Now, this matching plan has been "in practice" in many municipal projects and residential areas across the country: for example, in the municipal road renovation of a southern city, after using the AD inspection well + HDPE carat pipe, the water accumulation point in the rainy season last year was reduced by 80%; the drainage system of a newly built residential area did not experience a single inspection well leakage for three years, and the maintenance cost of the property was half that of the next residential area.

In fact, the "improvement" of the drainage system is never a "single fight" of a certain product, but a "tacit cooperation" of each component. Through the system design of "inspection well matching HDPE carat pipe", AD Pipeline has turned "pipeline" and "inspection well" into a "pair of partners", which solves the problem of "fragmentation" of the traditional drainage system from the source and makes the underground "blood vessels" more unobstructed and durable.

For the city, such a "perfect system" is the "invisible line of defense" to deal with heavy rain and protect people's livelihood - and this is the understanding of "system solution" by AD Pipeline as a plastic pipeline brand: not to sell a pipe or a well, but to make every component "fit together" and make the entire drainage system "more reliable".
