Tested sewage inspection well 5, sewage inspection well to be checked 9 are brick, concrete prefabricated or heavy-caliber plastic pipe is made.
Sealing medium is vaseline or water.
Embodiment:
Inspection chamber is smeared sealing medium → the lay equipment of the holding one's breath → air that adds high pressure and is carried out Air－tight Test → venting and dismounting equipment hold one's breath major equipment and preparation:
1, pressure bladder adopts annular air-pocket, and the pit shaft place gets pumping valve inside and tensimeter are installed on the air bag intermediate plate.
2, inflation and air pressure opertaing device mainly are air compressor machines.
The Specific construction step is as follows:
1, sewer line install one section (or multistage) inspection chamber build by laying bricks or stones finish after, to carry out leakproofness test by the quality inspection requirement.The place that first inspection chamber and pipeline junction, cover plate installation place etc. is leaked air easily checks that range estimation is without the gas leakage suspicious points.
2, the sealing of the sewer line mouth of pipe: about 0.3 meter of homonymy pipeline opening in adjacent two inspection chambers (in the pipe), at tube wall water spray or coat vaseline, pressure bladder is installed, four L shaped claws are stuck on the mouth of pipe, give airbag aeration with air compressor (or using inflator), be forced into 0.15-0.20MPa, with pipe sealing.Tighten 4 fastening screws on the wheel hub inwall, guarantee that air bag is unshift when pressurization detects.L shaped claw and plastic conduit contact point adopt rubber blanket, hinder plastic tube in case stop loss.
