Application case of Shandong Jianlong HDPE siphon drainage pipe in highway drainage project

Product Applications and Advantages

(I) Expressway Drainage and Water Permeability

Jianlong brand HDPE siphonic drainage pipes were installed in the roadbed drainage system of this section. The black pipe body is UV-resistant and aging-resistant, maintaining stable performance even under prolonged outdoor exposure. Its service life is up to 50 years, meeting the long-term use requirements of expressway drainage facilities. Furthermore, its smooth inner wall offers low friction and high drainage efficiency, quickly draining rainwater from the road surface and preventing road surface water accumulation that could impact driving safety.

(II) Slope Soil and Water Conservation for Hillside Development

Jianlong brand HDPE siphonic drainage pipes were used to construct a slope drainage system for the slopes along the expressway. The pipes offer excellent flexibility and are resistant to geological changes, adapting to topographical variations and minor geological activity. They also exhibit excellent low-temperature and corrosion resistance, operating stably within the region's temperature range of -40°C to 40°C. Even when buried in the slope soil, they resist soil corrosion for a long time, effectively channeling rainwater from the slopes, preventing soil erosion caused by rainwater scouring and ensuring slope stability.

(III) Construction and Installation

Jianlong brand HDPE siphonic drainage pipes are lightweight and easy to install, transport, and connect, significantly reducing construction complexity. The construction team used welding to connect the pipes, creating a seamless connection between the joints and the pipes. This eliminates the possibility of joint leakage, ensures a tight seal on the drainage system, conserves water, and avoids soil collapse caused by leakage.

Project Results

After the completion of the expressway drainage project, inspections during the rainy season revealed no significant waterlogging on the road surface, and soil erosion on the slopes was effectively controlled. Jianlong brand HDPE siphon drainage pipe, with its excellent performance, provides reliable protection for the drainage and ecological protection of the highway, and also provides a reference example for the construction of drainage systems in similar highway projects.
