Seized sewer line 7 is plastic tube, steel pipe or concrete prefabricated pipe with sewer line 10 to be checked.
Seized sewage inspection chamber 5, sewage inspection chamber 9 to be checked is brick, concrete prefabricated or heavy-caliber plastic pipe is processed.Embodiment:
Pre-buried plastic conduit when inspection chamber is built by laying bricks or stones → the lay equipment of the holding one's breath → air that adds high pressure hold one's breath test → venting and dismounting equipment hold one's breath major equipment and preparation:
1, circularity and the tightness when placing air bag for guaranteeing the inspection chamber pit shaft wanted 0.5 meter of a pre-buried segment length in the inspection chamber pit shaft stage of building by laying bricks or stones, and internal diameter is 0.7 pvc plastic conduit.Adopt the sealing binder that the plastic conduit bottom is bonded together with pit shaft, around plastic tube, lay pit shaft.The pre-buried plastic tube at inspection pit shaft place will install, and excessive pressure is not arranged when building the inspection pit shaft by laying bricks or stones, to prevent the plastic conduit distortion.When holding one's breath experiment, in this plastic pipeline, fill in pressure bladder, can stop to check the not round gas leakage that is brought of pit shaft.Critical piece and installation method are as shown in Figure 1.
2, 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.
3, inflation and air pressure opertaing device mainly are air compressor machines.Concrete construction procedure is following:
1, installs after one section (or multistage) inspection chamber builds completion by laying bricks or stones at sewer line, will carry out the leakproofness test by the quality inspection requirement.Earlier inspection chamber and the place that pipeline junction, cover plate installation place etc. leak air are easily checked that range estimation does not have the suspicious points of gas leakage.
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); Water spray or coat vaseline on tube wall; 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, to prevent to damage plastic tube.
