Brief introduction of glass reinforced plastic sand pipe
Glass fiber reinforced plastic has the advantages of light weight, high strength, liquid resistance, chemical and electrical good corrosion resistance and long service life, low cost comprehensive sand pipeline, is the national advocate for environmental protection materials; and the pipeline does not need the special antiseptic treatment, the length of an iron and the cement pipe joints, these relatively reduced. The installation and maintenance costs.
Glass fiber reinforced sand pipe construction preparation:
1, material approach acceptance
The use of gfrpmp has qualified product inspection report and product quality guarantee; the inner surface of glass reinforced plastic mortar pipe should be no cracks, delamination, pinhole, impurity, poor adhesive area and the outer surface of the pipe bubble; there should be no obvious defects. The end face of glass fiber reinforced sand pipe shall be flat, smooth and without burr, and the surface of socket and socket should be smooth. The rubber ring of sewage pipe adopts chloroprene rubber, and the rainwater pipeline adopts natural rubber.
Requirements for storage of glass fibre reinforced plastic sand pipe:
1, pipe hoisting using double hanging point, is strictly prohibited through the rope through its ends; and the use of finished hoisting belt, not allowed to use wire rope hoisting.
2, pipe directly stored in the ground, the ground to be flat, forbidden to put it in hard sharp, all piled up to prevent pipe wedge rolling.
3 、 glass fiber reinforced sand pipe, pipe should be stacked away from the heat source, open flame place.
4, buried pipes used in stacking should not be long-term outdoor exposure, in case of ultraviolet radiation.
5, rubber ring should be stored in a cool, clean environment, shall not be exposed to the sun; shall not be involved in swelling and corrosion of oil contact.
6, the preparation of on-site construction technology program, and approved by the supervision.
7, according to the site delivery data and relevant regulations, set temporary level points, control piles, etc., and completely keep the corresponding original records.
8. Construction measures for drainage, precipitation and trench support shall be established for underground water level section.
