Abstract
The invention relates to a well lid, which comprises a lid body, wherein the lid body is formed by a round panel with a skirt and a stiffening rib which is arranged along the axial direction of the round panel, and the panel with the skirt and the stiffening rib are integrally formed into a whole body. Because the lid body which is formed by the panel with the skirt and the stiffening rib arranged on the panel is adopted, the well lid is applicable to covering underground box culverts, pipelines, blind ditches and surficial channels, bears the ground load of pedestrian and vehicles, so the loading capacity of the well lid is improved, the dead weight (which is lighter than the dead weight of a cast iron well lid, and is greatly lighter than the existing cement well lid with a common structure) is also reduced, and the well lid provides convenience for people to open. Moreover, the lid body is made from cement-base composites, and the materials of the well lid have no recovery value, so the well lid cannot be stolen.
Description
Technical field
The present invention relates to a kind of well lid.
Background technology
Existing well lid generally adopts cast iron to make, and is often stolen because material has recovery value, loses seriously, and vehicle damage and personnel casualty accidents take place inspection shaft often that lose well lid.For antitheft, people one use anti-theft device, for example Chinese patent 95241036,96232738,9927151 or the like in the textural consideration of well lid; The 2nd, on material, consider to make its no recovery value, and for example Chinese patent 97202338,972207516,99231650.2,0213823.9,200510118301.5 or the like.The problem that their exist is: (one) takes the cast iron anti-stealing manhole cover that locks between well lid and walling crib, and no matter how antitheft office tightly still can steal for stealer intentionally, and for the surfaceman, is difficult to open because of the lock core corrosion again.(2) the ordinary construction well lid of existing cement-based material making is from great, and artificial unlatching is difficult.And its periphery is broken easily, and serious meeting integral body collapses.(3) well lid that adopts resin-based materials to make, the non-constant of its anti-wear performance, easily aging, the bearing capacity decay is fast, and under the heavy traffic load action, its safe handling cycle is shorter.(4) need reinforcing bar or steel plate to make skeleton in the well lid lid that existing cement based and resin-based materials are made, thereby still can be stolen unavoidably.
Summary of the invention
Problem to be solved by this invention provides a kind of well lid that is applicable to the passage on the underground box culvert of capping, pipeline, covered conduit and ground, and this well lid not only has advantages of high bearing capacity, and weight is lighter, is convenient to artificial unlatching.
Technical scheme provided by the invention is: a kind of well lid, comprise lid, and lid constitutes by the round panel of band shirt rim with along the stiffening rib that radially is provided with of round panel, and the panel and the stiffening rib of band shirt rim are one-time formed integral body.
