Abstract

The invention relates to a multi-layer molded high-load-bearing municipal road well lid and a manufacturing method thereof, and belongs to the technical field of municipal engineering roads. The well lid comprises a wear-resistant layer, a fixed supporting layer, a protective layer, a first filling layer, a first reinforcing layer, a second filling layer, a second reinforcing layer, a third filling layer, a third reinforcing layer and a fourth filling layer, wherein the upper surface of the protective layer is covered with the fixed supporting layer, the wear-resistant layer is installed on the fixed supporting layer, the first reinforcing layer, the second reinforcing layer and the third reinforcing layer are sequentially arranged in the protective layer from top to bottom, the space between the top face in the protective layer and the first reinforcing layer is filled with the first filling layer, the second filling layer is filled between the first reinforcing layer and the second reinforcing layer, the third filling layer is filled between the second reinforcing layer and the third reinforcing layer, and the fourth filling layer is filled between the third reinforcing layer and the inner bottom surface of the protective layer. By the adoption of the multi-layer reverse tensioning force enhanced curved surface type structure, stress in the well lid is more uniform, and the strength is better.

Description

technical field [0001] The invention relates to a multi-layer molded high load-bearing municipal road manhole cover and a manufacturing method thereof, belonging to the technical field of municipal engineering roads. Background technique [0002] A manhole cover is a closure to the top of the entrance to an underground facility. Municipal roads are often equipped with inspection wells for rainwater drainage, cables, etc., and manhole covers are used to cover the roads and prevent people or objects from falling. The existing polymer composite manhole covers have many advantages such as wear resistance, weather resistance, corrosion resistance, and anti-theft, and have gradually replaced traditional cast iron manhole covers, cement manhole covers, and waste sand manhole covers. The structure technology, manufacturing method and material formula of the polymer composite manhole cover are the key elements that affect the load-bearing capacity and service life of the manhole cov...
