Reinforced manhole cover
The invention relates to the technical field of manhole covers and discloses a reinforced manhole cover. The reinforced manhole cover comprises a round manhole seat and a manhole cover body, wherein the side surface of the outer circle of the manhole seat is provided with a pre-buried ring; the inner circle of the upper end of the manhole seat is convex upwards to form a convex ring; the lower end of the manhole cover body is provided with a connection ring which is rotatably buckled on the convex ring; a plurality of bolt holes are formed in the top part of the convex ring; countersinks are formed in the manhole cover body, and bolts which are connected with the bolt holes are arranged in the countersinks; a support ring is arranged on the upper end of the inner circle of the convex ring; the upper end surface of the support ring is a conical surface; a reinforcing ring is arranged on the bottom surface of the manhole cover body; the outer side surface of the reinforcing ring is in contact support with the conical surface on the support ring; the part, which is located inside the reinforcing ring, of the bottom of the manhole cover body is provided with crossed reinforcing ribs; and the outer ends of the reinforcing ribs are connected with the reinforcing ring. Therefore, the reinforced manhole cover disclosed by the invention has the beneficial effects of being convenient to change, high in compressive property and long in service life.
