HDPE Carat Pipe Scheme for Reducing Construction Earthwork

In municipal drainage, industrial pipe network and other projects, the amount of construction earthwork has always been the core pain point that plagues the project party - the accumulation of earthwork and high transportation costs caused by large excavation not only slow down the construction period, but also may damage the surrounding environment. How to reduce the amount of earthwork excavation from the root while ensuring the performance of the pipeline? The HDPE carat pipe solution of AD Pipeline gives a targeted solution path.

In traditional pipeline construction, in order to ensure the bearing capacity, it is often necessary to lay a sand and gravel cushion layer with a thickness of more than 300mm, and at the same time reserve a wide groove for operation, which directly leads to the soaring amount of earthwork. The HDPE carat pipe adopts a three-layer wall structure design, the inner layer is smooth and drag-reducing, and the outer layer is wear-resistant. The middle layer greatly improves the ring stiffness through mesh enhancement technology (up to SN8 and above). This structural feature makes it unnecessary to rely on overly thick cushions - in practical projects, only about 150mm of sand and gravel foundation is required to meet the requirements, and this alone can reduce the amount of foundation earth excavation by about 40%.

flexibility is another major advantage of AD HDPE carat pipe. The material itself has good impact resistance and bending properties, and can adapt to minor fluctuations in the terrain or slight settlement of soft soil foundation. There is no need for large-scale leveling of the base. For example, in an old urban drainage renovation project, the original road surface is uneven. The traditional pipeline needs to be dug to a depth of 1.8 meters for leveling, while the use of AD carat pipe only needs to be dug to a depth of 1.2 meters, which directly reduces the amount of earthwork by 33%, and avoids disturbance to the surrounding building foundation.

The improvement of connection efficiency also indirectly reduces the amount of earthwork. The AD HDPE carat pipe adopts hot melt socket connection technology, and the interface is heated and fused to form a whole, without additional anti-corrosion treatment or large connection equipment. This fast connection method shortens the exposure time of the trench, and there is no need to reserve too much earthwork accumulation space for "waiting for connection" - the traditional pipeline trench needs to be 1.2 meters wide, while the carat pipe only needs 0.8 meters, the width of the trench is reduced by 33%, and the corresponding earthwork excavation volume naturally decreases.

What is more worth mentioning is that the AD HDPE carat pipe is compatible with non-excavation construction technology (such as guided drilling). In the busy main road or green belt area, there is no need to excavate the whole line, only the work pit needs to be excavated at both ends, and the pipeline is pulled to the ground through the drilling rig. In an urban trunk road renovation project, after using this scheme, the amount of earthwork was reduced by 75% compared with traditional excavation. During the construction period, road traffic was not significantly affected, and environmental damage was minimized.

As the core support of the scheme, the quality control of carat pipes by AD Pipeline runs through the whole production process: from the screening of imported HDPE raw materials, to the precise control of temperature during the extrusion process, to the ring stiffness and pressure resistance testing of each pipe to ensure stable product performance - which is also the fundamental reason why it can "reduce earthwork with confidence".

From structural design to construction adaptation, the AD HDPE carat pipe scheme has achieved a systematic reduction in the amount of earthwork through four paths of "cushion, suitable terrain, fast connection, and non-excavation". In actual projects, the solution can reduce the amount of earthwork by an average of 30% -75%, while taking into account the construction period, cost and environmental benefits. For construction parties pursuing "high efficiency, low carbon and economy", this is not only a pipeline choice, but also a solution to optimize the whole process of the project.
