What does the word above the Manhole Cover represent?
Usually we will see a lot of words printed on the manhole cover on the road. What do these words mean?
The use of manhole covers is very extensive. The types of pipes with manhole covers in cities are generally divided into: water pipes, power pipes and cable trenches, municipal pipes, and communication pipes (telecom, mobile, China Unicom, radio and television, etc.). Generally responsible woody will require the use of the load cover, use and contact telephone number on the manhole cover used, and some also indicate the size and parameters of the manhole cover, which is convenient for installation and construction. As shown in the figure of the sewage pipe cover:
Waste: special pipeline inspection well for industrial wastewater;
Electricity: buried cable line inspection well;
Sewage: domestic sewage, other urban sewage pipeline inspection wells;
Rain: special pipeline inspection well for rainwater discharge;
Water: domestic water pipeline inspection well;
The composite Resin Manhole Cover
is one of the large manhole covers required for urban construction at this stage. The product features of the Composite Manhole Cover
1. Strong anti-theft performance: The resin composite manhole cover is made of unsaturated resin, glass fiber and other materials and steel frame by special production process. After high temperature grinding and molding, the material has no use value. It is very difficult to take out the steel bar. Exceeding the value of the steel bar) therefore has the function of active anti-theft.
2. Large bearing capacity: The bottom of the bottom adopts a special pot bottom structure, which increases the force area by a dozen times or even dozens of times. The continuous reinforcing fiber yarn used ensures the fiber filament and the glass fiber cloth together in a material, so that the product has sufficient carrying capacity.
3. Long service life: By using high-performance resin, glass fiber and special production process formula, the resin is ensured to run in the glass fiber, which greatly enhances the adhesion between the two, so that the material does not under the cyclic load. Internal damage is created to ensure the longevity of the product and the superiority of other resin composite well covers. Eliminate the disadvantages of poor adhesion.
4. Beautiful and practical, high grade: According to customer needs, we can make complex LOGO and multi-color personalized design on the same manhole cover surface, making the pattern delicate and brightly defined. According to the customer's requirements, we can make all kinds of imitation stone surfaces and colors that are the same as various stone pavements.
5. High temperature resistance/low temperature, good insulation performance and strong corrosion resistance: the product is resistant to corrosion and metal-free additives, which has the effect of insulation. It can be used in places that are complex, varied, and demanding. The product has been tested by relevant testing institutions and has obvious acid and alkali resistance and corrosion resistance.
6. Environmental protection, non-slip, low noise: This product does not slip, no harsh noise and reverse phenomenon after the car is crushed. At the same time, due to the light weight of the product, the cover and the seat are tightly closed, which overcomes the problems of "jumping, smashing, ringing, shifting" of other inspection manhole covers.
