Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to an anti-settling ductile iron manhole cover. Background Art

[0002] Ductile iron manhole cover is a kind of ductile iron product. Ductile iron is treated by spheroidizing and inoculating to obtain spheroidal graphite, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thereby obtaining a higher strength than carbon steel. The patent document with announcement number CN202809656U discloses a new type of adjustable anti-settling ductile iron manhole cover, which consists of a cover plate and a support; the upper part of the support is a flange-type upper disk, and the lower part is a socket-type structure. The outer diameter of the flange-type upper disk is 150 to 300 mm wider than the outer diameter of the cover plate, making the manhole cover a complete part of the road surface, dispersing the load directly to the road surface structure layer, protecting the road surface around the manhole cover, and preventing the manhole cover from settling. The socket-type structure is 100 to 200 mm high, so that the connection between the manhole cover and the well body is a socket-type, that is, the socket-type structure fits tightly with the inner wall of the well body, further preventing the manhole cover from settling. The above-mentioned anti-sinking ductile iron manhole cover has the following defects: 1. Only an embedded rubber strip is provided between the cover plate and the support, which cannot buffer the pressure well and is prone to sinking; 2. The cover plate is prone to displacement when under pressure and is prone to collision with the upper plate surface, making noise. Utility Model Content
