Abstract
The utility model discloses a single-layer double-protecting manhole cover, which consists of a well cover and a well pedestal, wherein, a preformed steel plate is arranged on the side of the well cover; the inner wall of the well cover is provided with a groined reinforced rib; the inner wall of the well pedestal is provided with a lug boss; and preformed steel plates which are parallel to the well cover are respectively arranged on the inside and the outside of the well pedestal wall on the lug boss. The single-layer double-protecting manhole cover has a reasonable structure; the well cover and the well pedestal are cast by adoption of flat steel fibers, a reinforcement cage and sand and stone concrete, thereby the cost is low; and the single-layer double-protecting manhole cover not only solves the problem that the manhole well cover and the well pedestal are frequently stolen but also solves the problem of invasion of rainwater and dust.
Description
Technical field
The utility model relates to the ancillary facility technology in the road construction, relates in particular to well lid and well seat on passage, the place manhole, is the two manhole covers that protect of a kind of individual layer specifically.
Background technology
