Plastic waterstops and supporting materials used in waterproofing layers Must comply with design requirements and relevant national standards. Factory certificate, quality inspection report and on-site sampling test report.
The laying of the waterproof layer should comply with the following regulations. The buffer liner of the plastic waterstop should be fixed on the base layer with a hidden nail ring. The plastic waterstop should be welded firmly to the hidden nail ring while laying. The overlap width of the plastic waterstop is such that the lower waterproof plate presses the upper waterproof plate. The overlap joint should be welded with double welds, and the effective welding width of a single weld should not be less than.
For the construction quality acceptance of plastic waterstops
The number of construction quality inspections of plastic waterstops should be based on the laying area of each location but not less than one location. The overlapping seam uses hot air welding to leave a cavity in the middle of the double weld seam for inflation inspection. Inspection method: Connect the No. 2 injection needle to the pressure gauge and use an air pump to inflate the cavity between the double welds. The length of the inflated double seams is ~ When inflated, the inspection hole will bulge. When the inflation pressure between the double welds reaches... If the air pressure drops by more than %, it proves that there is no benefit. Apply soapy water to the weld and the bubbles must be re-welded. Use a handheld welding gun or soldering iron to repair the welding until there is no air leakage. The inspection of single seams and shaped joints and repair points can be determined by mechanical inspection with a screwdriver or by visually observing whether the molten slurry of the weld is melted.
