What are the polyethylene manholes applications?
Manholes made of polyethylene have various applications due to their plastic structure, offering a longer lifespan compared to manholes made of traditional building materials. It’s essential to note that the useful life depends on the working conditions in which the manholes are used. The polished surface of polyethylene manholes makes maintenance and cleaning much easier. Here are some notable applications and advantages of polyethylene manholes:
1. Applications in Sewage and Power Cable Transmission Lines:
Polyethylene manholes are used in sewage networks to provide better access, service, and maintenance of pipelines. They also serve as inspection stations in power cable lines for inspecting cable health and conducting repairs. Polyethylene manholes are resistant to water, animals, and plant growth, with a lifespan of up to 50 years.
2. Review of Manhole Applications in Terms of Structural Design:
Polyethylene manholes are manufactured in a factory using molds that are designed based on advanced engineering technologies. The molds follow the model of German polyethylene manholes and result in a predefined and precise structure. This manufacturing process is efficient and allows for the replacement of old manholes in a short period.
