Features:

· The special design of the well frame makes the well frame not directly sit on the well head, but as a part of the road surface. Therefore, the subgrade can bear most of the pressure from the manhole cover. Under the action of external force, the well frame will follow the road surface. Ascending and descending, so that the road surface is kept on the same level;

· Special self-locking spring can prevent the manhole cover from jumping, and the shockproof rubber ring can prevent the manhole cover from vibration and avoid noise; suitable places: highways, urban roads, national highways, etc. sections.

The materials used for the new type of ductile iron anti-theft manhole cover are high-quality ductile iron pig iron, ferrosilicon and special spheroidizing agent from a special designated production plant. The spheroidization grade is controlled within the range of level 1 to level 2. The appearance is fine, and the color is compared with the asphalt surface layer. It is close and the concrete well ring can not be exposed. Under the premise of ensuring the flatness, the manhole cover is integrated into the pavement and the road to achieve the effect of beautifying the city. However, the old gray cast iron manhole cover, because of its dark color and rough appearance, the concrete well ring must expose the asphalt surface. The color is inconsistent with the asphalt surface and the flatness is difficult to control. It is difficult to integrate with the road. It is a difficult point in beautifying the city.

The new spheroidal graphite cast iron anti-theft manhole cover has a polychlorinated ether pad on the joint surface of the frame cover to increase the mating depth of the frame and the cover. Six-point contact is adopted to make the cover frame fit tightly and use the hinge together. Fastening bolts and anti-theft locks basically eliminate noise, reduce vibration, and basically eliminate the general noise problem of old gray cast iron manhole covers when they are impacted by cars and the phenomenon that they are carried away by car impact.

The product has anti-theft and anti-shock functions, and can be rotated by a large margin when it is opened. Its quality, performance, bearing capacity, reliability and safety have reached the international advanced level. In foreign countries, the products are mainly sold to South Korea, Japan, Italy, Britain, Germany, the United States and other countries.
