Abstract
The utility model relates to a man hole cover for a pipeline. The utility model is integrally connected by a metal outer ring, a metal grid, an opening cover and concrete. The utility model has the advantages of simple manufacturing process, raw material saving, low cost, high strength and high safety.
Description
The utility model relates to a kind of novel pipeline manhole cover, is mainly used in communication cable, cable television, transmission line of electricity, the lid of the inspection manhole of underground pipelines such as heat supply water supply.
Traditional pipe manhole lid is by metal material cast form, and there are several like this shortcomings in it, the one, and the manufacturing process complexity, the 2nd, the cost height, the 3rd, intensity is low, and the 4th, because the recuperability of metal material and the characteristics of self structure performance thereof cause very easily stolen.
The purpose of this utility model just is to overcome and avoid the shortcoming and defect of prior art, and a kind of novel pipeline manhole cover is provided, and it is simple that it should have manufacturing process, saves raw material, reduces cost, and improves intensity, the characteristics of safe antitheft.
The utility model is to adopt following measure to realize its purpose.
By the metal outer ring, metal grill is opened the pipe manhole that cover and concrete connect as one and is covered, and the inboard of its metal outer ring is evenly equipped with protruding thorn, and metal grill is in the Lower Half of manhole cover, and is connected with the metal outer ring.
The drawing of accompanying drawing is described as follows:
Fig. 1 is an elevation of the present utility model.
Fig. 2 is a sectional view of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
The utility model is by metal outer ring (1), metal grill (2), unlatching cover (3) and concrete (5) are connected in one, the section of metal outer ring (1) is stepped, its inboard is evenly equipped with protruding thorn (4), its effect is to combine securely for metal outer ring (1) and concrete (5), metal grill (2) is to be connected and composed by crisscross metal rib, it can add reinforced concrete (5) intensity and with the bonding strength of metal outer ring (1), metal grill (2) is placed on the bottom of manhole cover, opens cover (3) symmetric arrays.
The utility model manufacturing process is simple, saves raw material, and cost is low, the intensity height. In addition, Because the recyclable property of material of the present utility model is lower, so its security reliability is higher. Implement the utility model and can produce preferably economic benefit and social benefit.
