Features of SMC manhole cover products for gas stations:
1. High strength: it has high compressive, bending and impact strength and toughness. After long-term use, the product will not crush or damage the manhole cover, which can completely eliminate the occurrence of "urban black hole" accident.
2. Beautiful appearance: the surface pattern design is exquisite, the color is bright and adjustable, beautifying the urban environment.
3. Convenient use and light weight: the weight of the product is only about one third of that of cast iron, which is convenient for transportation, installation and rush repair, greatly reducing the labor intensity.
4. No recovery value, natural anti-theft; according to the needs of customers and equipped with a locking structure, to achieve anti-theft property in the well.
5. Strong weather resistance: the manhole cover can be used normally in - 50 ℃ ~ + 150 ℃ environment through scientific formula, advanced technology and perfect technical equipment.
6. Acid and alkali resistance, corrosion resistance, wear resistance, rolling resistance, long service life.
Construction scheme of gas station SMC manhole cover:
In order to keep the appearance of the cover beautiful and the surface pattern and handwriting clear, a thin sheet iron or wood board shall be used to cover the well cover during the construction of asphalt pavement, and the black well cover can also be brushed with waste oil to prevent the asphalt from spraying on the manhole cover.
The inner diameter, length x width and square circle of the brick masonry of the well cover shall be determined according to the well cover size designed by the Design Institute, which can also be executed according to the corresponding standards. A concrete protection ring with a width of 40cm shall be cast around the well cover, and the maintenance period shall be more than 10 days.
When installing the well cover on the asphalt pavement, it is necessary to avoid the construction machinery directly rolling the well seat. During the overall casting of the pavement, the hole slightly larger than the well seat shall be reserved on the pavement and placed after the asphalt pavement is completed.
After the well base is poured or paved with asphalt, the well cover shall be opened and cleaned in time to avoid mortar or asphalt from pouring the inspection well cover and the base into one, so as not to affect the opening in the future.
