Because the performance and quality of composite Manhole Cover have an important impact on public safety, the development and improvement of the manhole cover industry standard has realistic urgency and wide social significance, and the demand for Composite Manhole Cover is becoming more and more popular in society. The composite manhole cover has six major advantages over other manhole covers available in the market.
1. Anti-theft: The synthetic material has no recycling value and is naturally anti-theft; and it has a locking structure to realize the security of the property in the well. Can completely eliminate the occurrence of "urban black hole" accidents;
2.the appearance of beauty: inspection of the composite manhole cover surface design is exquisite, can be made into a variety of colors, beautify the urban environment;
3.high strength: the use of polymer synthetic materials, coupled with steel skeleton, high temperature molding, the maximum load of 900KN, in line with and exceed the latest GB/T23858-2009 standard issued by the Ministry of Construction of the People's Republic of China;
4.light weight: composite manhole cover product weight is only about one-third of cast iron, easy to transport, installation, repair, greatly reducing the labor intensity;
5.High precision: Because the product is molded by high temperature, the gap between the cover and the joint is small, which overcomes the problems of “running, jumping and ringing” of cast iron and cement manhole cover, which improves the road capacity and driving comfort;
6.Strong weather resistance: This product uses high molecular weight materials with large molecular weight and strong chemical stability as raw materials. Through scientific formula, first process and perfect technical equipment, the product can be used normally at -50 °C - 150 °C.
The most outstanding advantage of the composite manhole cover is that it does not use steel frame reinforcement, but is enhanced by glass fiber composite and belongs to GRC type products. Therefore, it has an unaffected advantage in the current situation of rising steel prices. Because it does not contain a bit of iron, it is more burglar-proof than stone and fiber concrete manhole covers.
Composite manhole covers are widely used in towns, factories and mines, and large-scale material distribution centers. The conditions of use vary, and the corresponding level of use should be determined. According to different conditions of use, the corresponding manhole cover products can not only meet the requirements of various roads and sites, ensure the safety and reliability of the manhole cover during use, but also make the most reasonable use of materials, avoiding waste of resources and reducing The cost of production and use of the manhole cover. The production of manhole cover according to the load level is conducive to the safe use of the manhole cover and the rational use of materials, which will produce good economic and social benefits.
At present, a large number of patented technologies involve composite manhole covers, and more and more enterprises are engaged in the research and production of composite manhole covers. With the sustained and rapid development of China's economy, composite manhole covers have become more and more widely used in urban planning and road construction.
