Product Features nine manholes acid corrosion, anti-aging, long life time injection molded thermoplastic parts, and by the National Chemical Building Materials Test Center tests. Material Safety green plastic manhole high-density polyethylene plastic, tasteless poison yuan, the use of recyclable, environmentally friendly building materials belonging to chemical, in line with state policies and principles of environmental protection. Uniform settlement, pressure pipes and wells seat flexible connection pipes and clay together well base movement, a good solution to the problem of uneven settlement traditional wicket well and produced a plastic pipe connections, prevent ground subsidence. Construction easy assembly using split structure, the wellbore can be cut on site to adjust, try using a variety of installation requirements, reduce costs and greatly improve the construction progress, shorten the construction period is 10 to 20 times more than traditional inspection wells; and all-weather construction, brick manholes and other masonry cement modules can not be compared with the well. Smooth and efficient drainage smooth wall with the flow channel, dirt easy retention, reducing the possibility of clogging, has excellent drainage, rainwater and sewage discharge rate is 1-3 times that of traditional manhole. Light weight, easy to transport and install reliable performance, strong carrying capacity; fit and strong, full range. Shaft height can be adjusted and the cylinder drilling, adjust the direction, to meet all the needs of the project installation. And lower total cost, lower maintenance costs than traditional inspection wells advantage; you can recycle and reuse, has a huge social benefits. Good sealing performance, anti-leakage due by way of a flexible connection: flexible, able to overcome the dust, sand gray harsh construction environment. But also to overcome the difficulties arising from increased road and not to duplicate inserts. Sealing performance, prevent rain water leakage. Leaks to prevent ground water contamination. Saving materials plastic manholes made of a polymer resin instead of a red brick cement processing materials, saving resources topsoil; building used by the cell size reduced, a significant reduction in inspection wells buried land occupied space.
