Plastic manholes why much attention?

Plastic manhole advantages of information (function) function plastic manhole five points: land, energy, water, materials, and environmental protection. (1) acid corrosion resistance, aging resistance, long service life. Components using a thermoplastic injection molded, and by the National Chemical Building Materials Test Center tests. (2) safety and environmental protection, good seal against leakage. Material Plastic manhole is a high-density polyethylene plastic, non-toxic, odorless, recyclable after use; tightness can be able to prevent rain water seepage, leakage, in order to prevent groundwater contamination. A chemical environmentally friendly building materials, in line with state policies and principles of environmental protection. (3) uniform settlement, compression. Block flexible connection pipes and wells, pipelines and wells clay together sport seats, a good solution to the problem of uneven settlement traditional inspection wells with plastic pipe connections generated, effectively prevent ground subsidence. (4) quick and easy construction. Using sub-assembled structures, the wellbore can live cut, adjust, adapt to a variety of mounting depth requirements, reduce costs and greatly improve the construction schedule, shorten the construction period is 10 to 20 times more than traditional inspection wells; and all-weather construction, brick inspection wells and other wells with cement block masonry can not be compared. (5) efficient drainage. Smooth wall smooth, has a diversion tank, easy dirt retention, reducing the possibility of clogging, has excellent drainage, rainwater and sewage discharge rate is 1-3 times that of traditional manhole. (6) Light weight, easy to transport and install, reliable performance, strong bearing capacity; fit and strong variety, can be adjusted in height and the cylinder bore drilling, adjust the direction, to meet all the needs of the project installation. (7) and lower total cost, maintenance cost less than traditional manholes advantage; you can recycle and reuse, has a huge social benefits. Good (8) sealing performance, anti-leakage. Because by way of a flexible connection: flexible, able to overcome the dust, sand gray harsh construction environment. But also to overcome the difficulties due to increased road and not duplicate inserted. (9) to save material. Plastic manholes replaced by polymer resin material of the red brick cement processing, saving topsoil resources; residential building used to narrow specifications, significant savings Manhole buried land occupied space.
