The invention discloses a casting round inspection shaft cover which comprises a framework body and a cover body, wherein the framework body is movably connected with the cover body through a stainless steel connection member, the stainless steel connection member is formed by a cover body single-sheet member and a framework body single-sheet member which are movably connected, and a support frame arranged on the cover body is matched with a framework-type groove on the framework body. The framework body is directly embedded in the road surface, and the cover body is movably connected onto the framework body through the stainless steel connection member so that thieves cannot steal the inspection shaft cover. Various liquid and gases in an inspection shaft all have the corrosion function, and service life of the casting round inspection shaft cover can be prolonged by means of the soft stainless steel connection mode.
Description
technical field [0001] The invention relates to a casting circular inspection shaft cover. Background technique [0002] The construction of urban underground drainage pipe network is inseparable from the manhole cover, especially the manhole cover installed on the road, which is basically cast, and the stability requirement is very high, because it directly involves the safety of pedestrians and vehicles. The stolen phenomenon of manhole cover often takes place in the city, and the main reason is that the manhole cover is not connected as one with the ground, so it is easy to be stolen by others. Contents of the invention [0003] The object of the present invention is to provide a cast circular inspection well cover which is integrally connected with the ground and is not easy to be stolen by others. [0004] The purpose of the present invention is achieved through the following technical solutions: the cast circular inspection shaft cover includes a frame body and a co...
