The invention relates to the field of urban building construction, in particular to a well cover structure. The well cover structure includes a well cover and a base installed in the wellhead; the well cover includes a decorative panel, an angle steel frame and a supporting layer; the supporting layer has an octagonal concave cavity, and the bottom of the concave cavity is provided with an end fixed concave The supporting protrusions on the inner wall of the cavity; flanges are provided on every side of the octagonal support layer; reinforcing ribs are provided under the flanges; the base includes an outer seat and an inner seat; The shaft is fixedly connected; the end of the shaft away from the shaft hole is provided with a shaft head; the well cover is provided with a through hole and a connecting piece; the well cover and the base are connected by an air bag, and the side of the air bag near the base is provided with a vent hole, and the top of the air bag is provided with an inflatable hole. Through the cooperation of the specific structure and positional relationship between the manhole cover and the base of the invention, the manhole cover can be guaranteed to be beautiful, have a decorative effect, be safe and firm without collapsing, and at the same time be difficult to be stolen.
Description
technical field [0001] The invention relates to the field of urban building construction, in particular to a well 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 formed on the upper surface of the spiral rib;...
