[0002] Manhole covers are used to cover deep wells on roads or at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round. They can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. Manhole covers are important components for closing the wellheads of inspection wells. In municipal engineering construction, manhole covers are often fixed directly on the shaft of the inspection well.
