1), acid and alkali corrosion resistance aging resistance, long service life. Part adopts the thermoplastic molded once, and through the national chemical building materials testing center testing.
(2), uniform settlement, compression. Piping flexibility is connected with the well seat, clay together movement, pipeline and the well base is a very good solution to the traditional inspection shaft and plastic pipe connection produce uneven settlement problem, effectively prevent the ground subsidence.
(3), convenient and quick construction. Using the split assembly structure, the shaft of field cutting, adjust, adapt to various installation depth requirements, effectively reduce the cost, greatly improve the construction progress, shorten the construction period is 10-20 times higher than the traditional inspection well; and all-weather construction, brick manholes and other cement module masonry well and cannot be compared.
(4), effective drainage. The inner wall is smooth, is provided with a guide groove, dirt can not be stranded, reducing the blockage may, with the outstanding performance of rain and sewage drainage, discharge rate is the traditional inspection wells 1 to 3 times.
(5), saving material. Plastic inspection well by polymer resin for processing materials to replace the red brick cement, saves topsoil resources; construction area for specifications narrow, greatly saves the inspection well buried the occupied land space.
