The specific requirements for the bearing capacity of resin composite manhole cover are as follows: A15 shall be selected at least in the areas where motor vehicles are forbidden to enter the green belt and sidewalk; B125 shall be selected at least for sidewalk, non motor vehicle lane, parking lot and underground parking lot; C250 shall meet the requirements of residential area, back street lane, and the area only driven by light motor vehicles or cars, and the distance between curbs on both sides of the road shall not be less than 0.5 m; urban multi-channel and high-speed For highway, high-grade highway, expressway and other areas, D400 shall be selected as the minimum; E600 station, wharf, airport and other areas shall be selected for freight transportation; f900 shall be selected at least for airport runway area.
What are the bearing capacity and common characteristics of resin composite manhole covers
1. Strong anti-theft performance: composite manhole cover manufacturers generally use unsaturated resin, glass fiber and other data, and through special production process composite. After high temperature molding, the product has no recycling value and is not easy to pull out the reinforcement.
2. Service life: through the use of high-performance resin, glass fiber and special production process formula, the permeability of resin composite manhole cover in glass fiber is ensured, and the bonding force between them is greatly enhanced, so that the material will not suffer internal damage under cyclic load, so as to ensure the service life of the product. It has the same advantages as other resin composite manhole covers The disadvantage of poor adhesion strength is eliminated.
3. High temperature / low temperature resistance, good insulation performance, strong corrosion resistance: corrosion resistance, non-toxic and harmless. No metal additives. It can be used in complex and changeable, harsh environment and demanding places. The manhole cover produced by resin composite manhole cover manufacturer has passed the inspection of relevant national authoritative inspection institutions. It has obvious acid and alkali resistance and corrosion resistance.
4. Beautiful and practical, high-grade: according to the needs of high-end customers, the complex logo and personalized design of various colors can be put on the same manhole cover appearance to make the pattern delicate, rich and clear. And according to the customer needs to make a variety of stone pavement, with the same stone appearance and color.
5. Strong bearing capacity: special design structure is adopted at the bottom, and continuous reinforced fiber is used to ensure that the fiber and glass fiber cloth are integrated in the material, so that the product has a certain bearing capacity.
6. Environmental protection, anti slip and low noise: manhole cover does not slip, and there is no noise and pollution after rolling.
