FRP sand pipe has light weight, high strength, low resistance to liquid transportation, good chemical and electrical corrosion resistance, long service life, and low comprehensive cost. It is also 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.

glass steel sandwich sand pipe construction preparation:

1. Acceptance of materials entering the site

The glass fiber reinforced plastic sand pipe used has a qualified product inspection report and product quality assurance; the inner surface of the glass fiber reinforced plastic sand pipe should be free of cracks, delamination, pinholes, impurities, poor glue area and bubbles; the outer surface of the pipe should be free of obvious defects. The end face of the glass fiber reinforced plastic sand pipe shall be flush, smooth and free of burrs, and the surface of the socket and socket shall be smooth; the rubber ring of the sewage pipe shall be made of neoprene, and the rainwater pipe shall be made of natural rubber.

Glass fiber reinforced plastic sand pipe storage requirements:

1. Double hoisting points shall be adopted for pipe hoisting, and ropes shall not be used to penetrate both ends of the pipe; finished hoisting belts shall be used, and wire ropes are not allowed for hoisting.

2. When the pipes are stored directly on the ground, the ground should be flat. It is strictly forbidden to put them on sharp hard objects. All stacked pipes should be added with wooden wedges to prevent rolling.

3. FRP sand pipe should be stacked away from heat source and open flame.

4. The pipes buried underground should not be exposed to the open air for a long time during stacking to prevent ultraviolet radiation.

5, rubber ring should be stored in a cool, clean environment, not in the sun exposure; shall not produce swelling and corrosion of oil contact.

6, the preparation of the site construction technical scheme and after the approval of the supervisor.

7. Set temporary leveling points and control piles according to the on-site pile delivery data and relevant regulations, and keep the corresponding original records completely.

8. Construction measures for drainage, precipitation and trench support shall be established for the section with underground water level.
