Gas station compound manhole cover mainly use unsaturated resins as the main chemical raw materials. They are compounded and modified with a variety of materials. After molding, they not only have high strength and beautiful appearance, but also have good electrical insulation properties, waterproof, aging resistance, acid and alkali resistance, strength. High, impact resistance, wear resistance, not afraid of sun and rain, antistatic, anti-theft and other characteristics, is an ideal substitute for cast iron manhole covers.
The gas station composite manhole cover is reinforced with mesh reinforcements, and the key stressed parts are specially strengthened. When an unavoidable external force impact occurs, the pressure can be quickly dissipated to ensure the safety of people and vehicles.
It does not contain metal, and the reinforced skeleton of stone plastic manhole cover and concrete manhole cover is less than 1/10 of the total weight of the manhole cover. Not much stealing value. And because the strength of the manhole cover is extremely high, it is extremely difficult to remove this small steel bar from the manhole cover.

The characteristics of gas station composite manhole cover products:
1. High strength: It has high compressive, bending and impact strength, and has toughness. After long-term use, the product will not be crushed and damaged, which can completely prevent the "urban black hole" accident.
2. Beautiful appearance: The surface pattern is exquisitely designed, and the colors are bright and adjustable to beautify the urban environment.
3. Easy to use and light weight: The product weighs only about one third of cast iron, which is convenient for transportation, installation and repair, which greatly reduces labor intensity.
4. No recycling value, natural anti-theft; according to customer needs, a lock structure is provided to prevent theft of property in the well.
5. Strong weather resistance: The manhole cover can be used normally in the environment of －50 ℃ ～ + 300 ℃ through scientific formula, advanced technology and perfect technical equipment.
6, acid and alkali resistance, corrosion resistance, wear resistance, rolling resistance of vehicles, long service life.
Gas station composite manhole construction scheme:
First, in order to maintain the beautiful appearance of the cover, and the surface pattern and handwriting are clear, the manhole cover should be covered with sheet iron or wooden boards during the construction of asphalt pavement. The black manhole cover can also be used to brush the cover surface with waste engine oil to prevent asphalt from spraying on the manhole cover.
Second, the masonry building of the manhole cover should be determined according to the size of the manhole cover designed by the design institute, its inner diameter or length X width, square circle, can also be implemented with reference to the standard, and a concrete protection ring with a width of 40cm is cast on the periphery of the manhole cover for maintenance. The period should be more than 10 days.
Third, when installing the manhole cover on the asphalt pavement, we must pay attention to avoid the construction machinery directly rolling the well seat. When the pavement is integrally cast, a hole larger than the well seat should be reserved on the road surface and placed after the asphalt is paved.
Fourth, after the well is cast or asphalt is laid in concrete, the well cover should be opened and cleaned in time to avoid mortar or asphalt from pouring the inspection well cover and the seat into one, so as not to affect the future opening.
