The advantages of plastic manhole are mainly reflected in portability, corrosion resistance, convenient construction, environmental protection and low maintenance cost.
The following is a specific analysis:
Lightweight and easy to install
The weight of plastic manhole is only half of that of traditional concrete well, which is convenient for handling and installation, significantly reducing the labor intensity of construction and improving the engineering efficiency.
Corrosion resistance and long service life
Plastic materials have acid and alkali corrosion resistance, which can effectively prolong the service life (up to more than 50 years) and reduce the frequency of maintenance or replacement caused by corrosion.
Strong water flow capacity The inner wall is smooth and designed with diversion groove, and the drainage efficiency is 1-3 times higher than that of traditional wells, which is especially suitable for drainage in rainy season and can effectively prevent water accumulation.
Environmental protection and energy saving The production energy consumption is low, and the materials can be recycled, which conforms to the development trend of green buildings. Seepage prevention and settlement prevention The rubber sealing ring is used for connection, which can adapt to the small angle displacement of the pipeline and avoid the leakage of sewage; Flexible structure design can prevent uneven settlement. cost advantage The later maintenance cost is low, and the construction speed is 10-20 times that of brick wells, which is suitable for large-scale engineering applications.
