Abstract

The invention relates to the field of urban building construction, in particular to an invisible anti-theft safety manhole cover structure. The improved invisible anti-theft safety manhole cover structure includes an invisible manhole cover and a base installed in the wellhead; its invisible manhole cover includes a surface filling layer, a matrix filling layer and a thermosetting polymer composite support layer; the base includes an integrally formed circular or oval The outer seat and the inner seat; the inner seat is provided with a circular or rectangular shaft hole and a rotating shaft passing through the center of the shaft hole and fixedly connected with the manhole cover; the end of the rotating shaft away from the shaft hole is provided with a shaft head; the inner bottom of the base is provided with a supporting structure, The support structure includes a concave upper arch support, an upward convex lower arch support and an auxiliary arch consistent with the arc direction of the corresponding arch support. The manhole cover of the present invention is invisible and useless for theft, and further prevents theft from the source; it can ensure the manhole cover is beautiful, has a decorative effect, is safe and firm and will not collapse.

Description

technical field [0001] The invention relates to the field of urban building construction, in particular to an improved invisible anti-theft safety manhole cover structure. Background technique [0002] In urban construction, all underground pipelines are auxiliary installed underground, and then maintenance pits are set up at intervals. The wellheads of the maintenance pits need to be protected by manhole covers. There are many kinds of manhole covers, which are convenient and practical. It is also found that although the existing well covers are practical, there are also certain weaknesses. When people enter the maintenance pit for maintenance, they must open the well covers. The well covers are sealed with dust for a long time and are difficult to open. [0003] CN102272385A (2011-12-7) discloses a manhole cover, comprising: a lower main body, the inside of which is hollow, a spiral rib is formed along the hollow inner peripheral surface, and a concavo-convex part is forme...
