Abstract
The invention relates to a water grate, which comprises a grate body, wherein the grate body consists of 4 to 20 square grids formed by crossly encircling 3 to 5 longitudinal beams and 3 to 6 cross beams; a group of patterns is engraved in each square grid; and the longitudinal beams, the cross beams and the patterns are molded integrally. The water grate is suitable for sealing entrances of underground box culverts, pipelines and blind ditches into which sewage and rainwater flow, allows water to pass through, intercepts impurities, bears loads of pedestrians and vehicles and can be opened. Compared with the conventional water grate, the water grate has a unique structural form and has high bearing capability; and the water grate has an exquisite structure and a larger water flow cross section compared with the conventional water grate which has an ordinary structure and is made of a cement-based material or a resin-based material. Moreover, the grate body is made of a cement-based composite material, so that the grate body does not have any recycling value and is theft-proof.
Description
Technical field
The present invention relates to a kind of drain cover.
Background technology
Existing drain cover 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 drain cover.For antitheft, people one use anti-theft device, for example Chinese patent 87201534,02214025.5,92240214.0 or the like in the textural consideration of drain cover; The 2nd, on material, consider to make its no recovery value, and for example Chinese patent 98120268.3,01206125.5,99248578.9,90101519.9,200420089819.1 or the like.The problem that their exist is: (one) takes cast iron Theft-proof gully grating that locks between drain cover and base, 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 drain cover of existing cement-based material making, its periphery is broken easily, and serious meeting integral body collapses.(3) drain cover 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) drain cover of the cement-based material of existing ordinary construction and the drain cover of resin-based materials, it is too little that it crosses the water cross section.(5) need reinforcing bar or steel plate to make skeleton in the drain cover 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 drain cover that is applicable to the inlet of box culvert, pipeline, covered conduit under capping sewage, the rainwater inflow place, and this drain cover not only has advantages of high bearing capacity, and it is bigger to cross the water cross section.
Technical scheme provided by the invention is: a kind of drain cover, comprise the grate body, and the grate body is intersected by 3-5 road longeron and 3-6 road crossbeam encloses 4 to 20 grids, is provided with one group in each grid and leaks flower, and longeron, crossbeam and leakage flower are one-time formed integral body.
