[Life phenomenon]
In ordinary life, we can often see manhole cover defects on the road, manhole cover being stolen ... This phenomenon is very common. Part of the pavement has too much debris and slips in from the wellhead, which will cause the pipeline to be blocked during drainage, the drainage will not be smooth, and the road area will have too much water in severe cases, which will affect road traffic safety. Arriving at the site for proper handling will directly affect the safety of pedestrians and vehicles in the past. This shows the importance of the quality of the manhole cover to our safety.
[Difference between composite manhole cover, cast iron manhole cover and cement manhole cover]
Before the composite manhole cover was used, most of the road covers were cast iron manhole covers and cement manhole covers. Then we will compare these three types of manhole covers.
1. Appearance: The appearance of composite manhole cover products is smooth and beautiful. Can be colored and designed according to design requirements. Cast iron manhole cover products are easy to rust, corrode, and have poor appearance. The surface of the cement manhole cover series is uneven and it is difficult to color.
2. Weight: The composite manhole cover series products are light in weight, about one third of the similar products of cast iron and cement.
3. Toughness: The composite manhole cover series has good toughness and is not easy to be brittle. Cast iron manhole cover series products have strong rigidity, lack of toughness, and are easy to be brittle. Cement manhole cover series products have strong solidity, lack of toughness and rigidity, and are easily brittle.
4. Vehicle running conditions: The cover of the composite manhole cover series is tightly combined, and the balance is free from warping and bouncing. The cast iron manhole cover products are not tightly combined with each other, which makes the vehicle bouncing easily and making a lot of noise when driving. Cement manhole cover series products are not tightly combined with the base seat, which makes the vehicle bouncing easily and causing damage when driving.
5. Maintenance situation: Because of its characteristics of corrosion resistance, light weight, colorability, and good airtightness, the composite manhole cover series products are easy to identify and open and maintain daily, reducing the labor cost of maintenance and the cost of renewal. The cast iron manhole cover series products are heavy, easy to rust and corrode, and easy to lose, increasing the difficulty of maintenance and the cost of replacement. The cement manhole cover series products are heavier, which makes maintenance more difficult.
6. Unit cost: The unit cost of composite manhole cover products is 40% lower than that of cast iron manhole cover products and 20% higher than that of cement manhole cover products.
[Product advantages of composite manhole cover]
1. Strong anti-theft performance: Resin composite material manhole cover is made of unsaturated resin, glass fiber and other materials and reinforced skeleton composited by special production process. After high temperature grinding and pressing, the material has no use value, and it is very difficult to remove the steel bar (rebar cost) (Beyond the value of steel), so it has the function of active anti-theft.
2. Large bearing capacity: the bottom adopts a special pan-bottom structure, which increases the load area by dozens or even dozens of times. The continuous reinforcing fiber yarn used guarantees that the fiber yarn and the glass fiber cloth are integrated into one material, so that the product has sufficient bearing capacity.
3. Long service life: through the use of high-performance resin, glass fiber and special production process formula, to ensure the running-in of the resin in glass fiber, greatly enhance the adhesion between the two, so that the material under the action of cyclic loading, not Internal damage occurs, which guarantees the service life of the product and the same superiority of other resin composite manhole covers. Eliminate the disadvantages of poor adhesion.
4. Beautiful and practical, high-grade: According to customer needs, complex LOGO and a variety of colors can be made on the surface of the same well cover personalized design, making the pattern delicate, bright and clear. According to customer requirements, we can make all kinds of imitation stone surfaces and colors the same as various stone pavements.
5. High temperature / low temperature resistance, good insulation performance and strong corrosion resistance: the product is corrosion-resistant and has no metal additives, which has a significant insulation effect. Can be used in complex, changeable, harsh, and demanding places. The product has been tested by relevant testing agencies and has obvious resistance to acid and alkali and corrosion.
6.Environmental protection, non-slip, low noise: This product does not slip, no harsh noise and anti-interference phenomenon after the car is rolled. At the same time, due to the light weight of the product and the tight closure of the cover and seat, it overcomes other problems such as "jumping, rocking, ringing, and shifting" of other inspection manhole covers.
We usually see a variety of manhole covers on the road, round, square, large, small, composite cast iron, cement, etc., each kind of manhole cover is different. In recent years, the utilization rate of composite manhole covers has become higher and higher, and everyone has gradually accepted this new type of light manhole cover. The previous concept was that the heavier the manhole cover, the better, and the thicker the better. Now it seems that the opposite is true. Manhole covers with the same carrying capacity, one is 80 kg and 8 cm thick. The other is 50 kg and 5 cm thick. So what would you choose? I definitely choose another. First of all, the two types of manhole covers have the same load bearing capacity. Why do n’t I choose the lighter one? It can save freight in transportation and save labor in installation. Why not? Lightness is a feature. In fact, the composite manhole cover has a prominent feature that the material itself has no secondary use value. Although the inside of the manhole cover is supplemented by steel bars, the cost of removing the steel bar is far greater than the cost of the steel bar itself, so the composite manhole cover has a natural anti-theft function. , Can directly solve the problem of stolen manhole cover.
