Description

Play arch form Drain cover

Technical field

The utility model relates to grate, specifically a kind of arch form Drain cover that rises.

Background technology

In the section of easily a large amount of ponding such as intersection, slope road breeze way, on the lower mouth of a river on road surface, conventionally traverse grate is installed.While raining, rainwater enters sewer by grate, to prevent a large amount of ponding in road surface.Under prior art condition, grate is plate shaped grate.Practice shows, plate shaped grate is because self structure is limit, and ubiquity easily ruptures, easily causes the problem of traffic accident.Particularly, plate shaped grate stands rolling of traffick for a long time, and based on the loading characteristic of slabbed construction, the central part of plate shaped grate, under the effect of rolling, depressed deformation will certainly occur.In the time that depressed deformation runs up to a certain degree, grate just can rupture.Once and grate ruptures, just can cause traffick that severe jolt occurs when by way of grate, cause thus traffic accident.Based on this, be necessary to invent a kind of brand-new grate, the problem that easily ruptures, easily causes traffic accident to solve existing grate.

Summary of the invention

The problem that the utility model easily ruptures, easily causes traffic accident in order to solve existing grate, provides a kind of arch form Drain cover that rises.

The utility model is to adopt following technical scheme to realize: play arch form Drain cover, comprise grate plate; The upper face of grate plate is plane; The lower face of grate plate is arcuate surface; The plate face of grate plate offers the drain hole of several up/down perforations.

Concrete use procedure is as follows: grate plate is traversed on the lower mouth of a river that is arranged on road surface, and ensure that the central axis of arcuate surface is vertical with road direction.In the time that traffick rolls grate plate, based on the loading characteristic of domes, the suffered grinding pressure of upper face central part of grate plate can disperse to be rapidly delivered to the edge, lower face front and back of grate plate, then disperse to be rapidly delivered on the road surface of road, the grinding pressure that makes thus the central part of grate plate bear significantly reduces, thereby the depressed deformation amount of the central part of grate plate is significantly reduced.On this basis, even if stand for a long time rolling of traffick, grate plate is also difficult for rupturing, and has also just effectively prevented thus the generation of traffic accident.Based on said process, described in the utility model arch form Drain cover, based on brand new, efficiently solves the problem that existing grate easily ruptures, easily causes traffic accident.

The utility model is rational in infrastructure, it is ingenious to design, and efficiently solves the problem that existing grate easily ruptures, easily causes traffic accident, is applicable to the section of easily a large amount of ponding such as intersection, slope road breeze way.

Detailed description of the invention

Play arch form Drain cover, comprise grate plate 1; The upper face of grate plate 1 is plane; The lower face of grate plate 1 is arcuate surface; The plate face of grate plate 1 offers the drain hole 2 of several up/down perforations.

When concrete enforcement, grate plate 1 is cast iron grate plate, and the upper face of grate plate 1 is rectangle plane; The cross section of drain hole 2 is rectangle.
