By using the special structure of the well frame, the well frame and the inspection well base are changed from the original "pier base type" connection to the "socket type" connection. The large frame is on the asphalt road surface, without external hinge. Through the pressure on the side and above of the well frame, the load of the inspection well is greatly reduced, which effectively solves the problem of road surface settlement and damage. By adopting three points The spring arm locking device can fix the cover and frame, prevent the well cover from jumping and reduce the noise.
Product features of resin composite anti subsidence manhole cover:
1. Strong anti-theft performance: the resin composite well cover is made of unsaturated resin, glass fiber and other materials and reinforced framework by special production process. After one-time forming by high temperature grinding, the material has no use value. It is very difficult to take out the reinforcement (the cost of taking out the reinforcement exceeds the value of the reinforcement), so it has the function of active anti-theft.
2. Large bearing capacity: special pot bottom structure is adopted at the bottom to increase the bearing area by ten times or even dozens of times. The continuous reinforced fiber used ensures that the fiber and glass fiber cloth are integrated from the material, so that the product has sufficient bearing capacity. And meet or exceed national standards.

3. Long service life: through the use of high-performance resin, glass fiber and special production process formula, the permeability of resin in glass fiber is ensured, and the adhesive force of the two is greatly enhanced, so that the material will not produce internal damage under the cyclic load, thus ensuring the service life of the product and the same superiority of other resin composite well covers. The disadvantages of poor adhesion are eliminated.
4. High / low temperature resistance, good insulation and corrosion resistance: the product is corrosion-resistant and harmless. No metal additives. It can be used in complex, bad and demanding places. The products have been tested by relevant national testing institutions, and have obvious acid and alkali resistance, corrosion resistance and other indicators have reached and exceeded the national standards.
Product characteristics
Resin composite anti settling well cover is made of polymer composite material, which has no recovery value. After the resin well cover is popularized, the problem of city black hole caused by stealing well cover will be solved. Different from the well cover on the market, it is pressed out by hydraulic press, with high impact strength. " This kind of resin composite well cover is made of glass fiber and resin as basic materials, curing agent, accelerator and other auxiliary materials. Its weight is two-thirds lighter than the cast iron well cover, its service life is more than 20 years, twice as long as the cast iron well cover, and its price is only 80% of the cast iron well cover. At the same time, the well cover has the characteristics of insulation and no noise.
