The management responsibility of the inspection well facilities belonging to the property right unit of each well cover is clearly defined, which provides the basic legal basis for the standardized and institutionalized management of the inspection well facilities. However, the formulation and promulgation of relevant laws and regulations by the government departments is only one aspect of strengthening the comprehensive management measures of urban pavement well cover. In order to effectively improve the management status of urban pavement well cover facilities, it is also necessary to objectively and comprehensively analyze and study the practical problems and causes in all aspects, through the unified leadership, organization and coordination of the relevant government departments, and the relevant responsibility management sheet Strengthen cooperation with departments and even the whole society, and take targeted management countermeasures and measures from all aspects.
The composite manhole cover has high toughness and high strength. The product has the characteristics of anti-aging, natural theft prevention and so on. So how to maintain the composite well cover?
The polymer composite manhole cover is a kind of metal with high density and toughness, which is based on unsaturated polyester resin and reinforced by glass fiber. It has two-way mechanical characteristics.
After a well cover is used in the device, because the vehicles on the road flow constantly, when the wheel is used for a long time, the composite well cover will show cracks and collapses. When this situation is presented, first check whether the foundation is reliable. If the foundation is not reliable, it needs to be reinforced. Then apply a layer of cement on the surface of the well cover for necessary reinforcement, and sprinkle some salt around properly, which will make the cement and the well cover more firmly posted, so it is not easy to fall.
The product uses unsaturated resin as the main chemical raw material, supplemented by a small amount of reinforcement, and is molded once through high temperature molding. It is a new type of environmental protection manhole cover, which can be mass produced. The products have been tested by the national chemical building materials testing center, and all the performance indexes have reached the CJ / T121-2000 standard of the construction department, which is at the leading level in China. This product not only can replace the traditional cast iron, cement products and hand paste resin products, but also has no recycling value, no impact noise, corrosion resistance, friction resistance, pressure resistance and high temperature resistance, and has the advantages of arbitrary coloring. It not only fundamentally solves the problems of urban traps, but also improves the taste of urban roads and becomes the application product of urban roads and public sectors.
