First of all, the telecom manhole cover is a new type of environmental protection cover. The composite materials telecom manhole cover is a fiber reinforced thermosetting composite material made of unsaturated polyester resin by molding process. What are the advantages of molded composite manhole cover? The manhole cover produced by this method has the advantages of high polymerization degree, high density, good impact and tensile strength, wear resistance, corrosion resistance, no corrosion and no pollution.
Among them, the interior of the anti-theft resin manhole cover is reinforced with steel, and the key stress parts are especially strengthened. Under the inevitable impact of external force, the pressure can be quickly dispersed to ensure the safety of people and vehicles. There is no metal. In addition, due to the high strength of the manhole cover, it is extremely difficult to remove this small point of reinforcement from the manhole cover. The comprehensive performance of resin manhole cover is between cement manhole cover and iron manhole cover, which is better than concrete manhole cover. It can be used in the occasion of high technical requirements of manhole cover.
