What to do before construction of ultra-high quality FRP wound pipes
Glass fiber reinforced plastic sand pipe has light weight, high strength, low resistance to liquid transportation, good chemical and electrical corrosion resistance, long service life, low comprehensive cost, and is an environmentally-friendly material strongly advocated by the country; and the pipeline does not require special anti-corrosion treatment The length is longer than that of cast iron and cement pipes, and the joints are relatively reduced, which in turn reduces installation and maintenance costs.
FRP sand sandwich pipe construction preparation: The FRP sand sandwich pipe used for material acceptance inspection has a qualified product inspection report and product quality assurance certificate; the inner surface of the FRP sand sandwich pipe should be free of cracks, delaminations, pinholes, impurities, and poverty. Glue area and air bubbles; there should be no obvious defects on the outer surface of the pipe. The end face of the glass fiber reinforced plastic sand pipe should be flat, smooth and free of burrs, and the surface of the socket and the socket should be smooth; the rubber ring of the sewage pipe adopts neoprene, and the rainwater pipe adopts natural rubber.
Storage requirements for glass fiber reinforced plastic sand pipe: The pipe is hoisted with double lifting points. It is strictly forbidden to use rope to run through its two ends; and it is not allowed to use steel wire rope for hoisting. When the pipes are stored directly on the ground, the ground should be flat. It is strictly forbidden to place them on sharp and hard objects. All stacked pipes need wood wedges to prevent rolling.
FRP sand pipe shall be stacked away from heat sources and open flames. Underground pipes should not be exposed to open air for a long time during stacking to prevent ultraviolet radiation. The rubber ring should be stored in a cool, clean environment, and should not be exposed to the sun; it should not be in contact with oils that can cause swelling and corrosion.
Prepare on-site construction technology plan and approval by supervision. Set up temporary level points, control piles, etc. according to the site handover materials and relevant regulations, and maintain the corresponding original records completely. Drainage, precipitation and trench support construction measures should be established for sections with groundwater level.
