Abstract

The invention provides a novel manhole cover and belongs to the technical field of manhole cover manufacture. The edge of a cover body is in the shape of a slope; the inner wall of a protection ring, corresponding to the cover body, is in the shape of a slope; a metal net is placed in the cover body; the outer wall of the protection ring is provided with a fixing edge. The contact portion between the cover body and the protection ring is an inclined surface, so that when a heavy object is placed on the cover body, the cover body only sinks and the edge of the cover body is prevented from being broken; the metal net can serve as reinforcing ribs; the fixing edge can combine the protection ring and a road surface conveniently. The novel manhole cover is extremely firm, can effectively prevent theft, is safe and reliable in performance, and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of well cover manufacture, in particular to a novel well cover installed on the road. Background technique [0002] Existing well covers are mainly composed of a cover body and a retaining ring, and are used on the wellheads of the sewer wells of municipal facilities and the wells of electric and optical cable pipelines. Because its manufacturing material is iron, the phenomenon of theft is very serious, not only loss of property, And cause unsafe hidden dangers. The cover body and retainer of the new manhole cover are made of cement concrete, which can prevent theft. Since the joint between the cover body and the retainer is a right-angled edge, the strength of the concrete is insufficient, and the edge of the cover body in contact with the retainer is easily broken and will appear. The case where the cover falls into the well. Therefore, it is necessary to further improve it. Contents of the invention ...
