The compound manhole covers is a closed object on the top of the entrance and exit to the underground facilities. It is necessary to install the well cover where the public facilities such as tap water, telecommunication, electricity, gas, heat, fire control, sanitation and so on are installed. With the rapid development of China's economy, China's infrastructure construction has ushered in a new cycle. The market demand for manhole covers in urban planning and road construction is huge. However, with the development of urban society, the demand for well covers is constantly upgrading, and the management strategy of new concepts is constantly updated. The compound manhole covers are often crushed and damaged, which leads to the decline of the safety of roads and facilities. Some road well covers collapse, shift and deformation, even run, jump and sound, causing great safety risks to the traffic roads.

In order to fundamentally solve the problem of serious theft of cast iron manhole covers for a long time, many manufacturers have developed many new anti-theft manhole covers from different materials. Compound manhole covers are made of glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcement materials, and synthetic resin as matrix materials. They are mainly composed of unsaturated polyester resin, filler, initiator, thickener, low shrinkage additive, film mold agent, pigment and reinforcement materials.
The composite well cover is so popular that its comprehensive performance and economic index are comparable to that of cast iron manhole cover, and it can also solve the problem of stolen cast iron well cover. At the same time, it can reduce the consumption of resources, which has important economic and social value. The resin manhole cover has the advantages of light weight and high strength, simple forming, low rolling noise, good chemical corrosion resistance, good acid and alkaline resistance, beautiful appearance, etc. it has the advantages that the cast iron manhole cover does not have: the surface pattern of the compound manhole cover is beautifully designed, the color is bright and adjustable, the city environment is beautified, the use is convenient, the weight is light, the resin manhole cover has no recycling value, natural anti-theft, resin inspection Through scientific formula, advanced technology and perfect technical equipment, the manhole cover can be used normally in the environment of - 50 ° C - + 150 ° C. , acid and alkali resistance, corrosion resistance, wear resistance, rolling resistance, long service life, in line with the resin well cover standard.
