Abstract

The invention relates to a novel well lid, which comprises an upper cover plate, a transverse frame, a longitudinal frame and a lower cover plate, wherein a circular reserved opening is arranged in the middle of the upper end of the upper cover plate; the reserved opening protrudes upwards on the upper surface of the upper cover plate; three arc-shaped load-bearing strips are arranged at the upperend of the upper cover plate; the three load-bearing strips are uniformly distributed on the upper surface of the upper cover plate; the bearing strips protrude upwards on the upper surface of the upper cover plate; the lower end of the upper cover plate is fixedly connected to the upper end of the transverse frame and the upper end of the longitudinal frame; and the lower end of the transverse frame and the lower end of the longitudinal frame are fixedly connected to the lower cover plate. A processing and preparation process of the novel well lid comprises the following steps of blanking, upper furnace heating, press forming, quenching, tempering, inspection and welding. The novel well lid can bear the pressure of 9 to 15 tons, and has the advantages of high strength, plasticity and toughness, strong reliability, good dimensional accuracy, lightweight products, convenience for movement, resource conservation and low cost.

Description

technical field [0001] The invention relates to a novel manhole cover and a processing and preparation method thereof, belonging to the technical field of municipal pipeline construction. Background technique [0002] Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. According to the material, it can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. Generally round or square, it can be used for green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. [0003] At present, the conventionally used manhole covers are often very bulky, and it is difficult for maintenance personnel to open the traditional municipal manhole covers. Due to improper construction, the traditional manhole covers can easily affect the overall aesthetics of the road; the manhole covers are easily deformed, hardened, aged, damaged, broken, Noisy and disturbing. Therefore, it...
