Description

Technical Field

[0001] The invention belongs to the technical field of reinforcement rib preparation, and in particular relates to a polymer manhole cover reinforcement rib drawing machine. Background Art

[0002] At present, the manhole covers on the market mainly include metal manhole covers and non-metal manhole covers. Non-metal manhole covers include: composite manhole covers and cement manhole covers. Manhole covers are covers for manhole openings set up for pipeline maintenance or cleaning. They are usually used to prevent vehicles, pedestrians and debris from falling in, and can be easily opened when maintenance is required. Metal manhole covers are made of cast iron. Metal manhole covers are easy to be stolen because of their recycling value, which can easily form safety hazards. Cement manhole covers are made of steel skeletons and concrete. Cement manhole covers are easy to be crushed or corroded by harmful gases in the inspection well due to the relatively weak toughness and anti-corrosion performance of concrete, which reduces the bearing capacity. Composite manhole covers are pressed by steel skeletons and chemical raw materials. The main compressive resistance of composite manhole covers is achieved by the steel skeleton in the manhole cover. The gripping force between the steel skeleton and the composite material is relatively weak. After being compressed, the composite material is prone to cracks. When the composite material has cracks, the steel skeleton in the manhole cover will be corroded by the harmful gases in the inspection well to produce rust, reducing the bearing capacity.

[0003] The polymer manhole cover reinforcement ribs are made of non-metallic materials, which solves the problem of corrosion and recycling of the steel frame. In addition, since these materials have no recycling value, the problem of manhole cover theft is fundamentally solved. Moreover, this type of manhole cover is lighter, has better corrosion resistance, does not require a maintenance period, and the production process is environmentally friendly.
