In urban traffic arteries, the laying of pipelines under pedestrian crossings has always been a difficulty in municipal engineering - not only to ensure smooth traffic, but also to ensure construction safety and efficiency. Traditional pipelines often face challenges due to heavy weight, complex interfaces, and weak adaptability. The emergence of HDPE carat pipes provides a better solution for this scene. Its core advantage of "construction convenience" is becoming a reliable choice for many projects.

From the perspective of material characteristics, HDPE carat pipes are made of high-density polyethylene raw materials, and the weight is only about 1/8 of that of concrete pipes of the same diameter. This means that under narrow pedestrian crossings, construction personnel can easily handle and install without large machinery, greatly reducing the investment in labor and equipment. At the same time, its unique structural design makes the pipeline interface simple and reliable. Whether it is an electrofusion interface or a hot-melt interface, it can be connected in a short time, and the interface has strong sealing performance, which effectively reduces the risk of leakage in the later stage and further shortens the construction period.

More importantly, HDPE carat pipe has good flexibility and impact resistance, and can adapt to complex terrain such as foundation settlement. In areas with large pedestrian flow and frequent changes in ground loads such as pedestrian crossings, it can reduce pipeline damage caused by settlement and reduce later maintenance costs. Compared with the problem that traditional pipelines require frequent maintenance, the durability and construction convenience of HDPE carat pipe make the project more advantageous in both early investment and long-term use. Whether it is the pipe network laying of the new road or the transformation and upgrading of the old pipe network, the application of HDPE carat pipe under the pedestrian crossing has provided strong support for the efficient promotion of municipal engineering due to its convenient construction, safe and reliable characteristics, and has become an ideal choice to connect the urban underground pipe network with convenient transportation.
