·Product advantage
1. Good corrosion resistance, acid and alkali resistance, aging resistance, long service life.
2. Using high-performance rubber seal flexible connection, flexible, convenient and good seal performance, can effectively prevent sewage leakage, protect the underground water.
3. And well tube joint movement, uneven subsidence, solve the traditional designed well build by laying bricks or stones and plastic pipe connection of uneven settlement problem.
4. Installation of portable, easy to transport installation, supporting shaft can be cut, the adjustment, to adapt to the various installation depth requirements, effectively reduce the use of
The cost.
·The selection of instructions
A, the cap should be selected according to the drainage pipeline conveying medium, set in place, wellbore diameter and pipe factors determine the wellbore.
Two inspection shaft on the manhole covers, sewage pipe should be "dirty" word tag, rainwater pipeline inspection Wells should be "rain" word mark in the manhole cover.
Three, wellbore diameter less than or equal to 315 mm. And the inspection shaft in green belts, appropriate USES hard harmonic poly ethylene material manhole cover;When the outdoor environment of the average temperature is below 10 ℃, should use of polymer matrix composites manhole cover;When installed in the roadway, should use a protective cover seat covers;In green need to be set greater than or equal to 450 mm shaft, the manhole cover on the roadway can be used, but not doing concrete foundation.
Four, in addition to have special requirements, a protective cover of sewage in inspection Wells wellbore flowing should also set up inside.
