Abstract
The utility model provides bridge floor drainage devices arranged in preformed holes at the two sides of a bridge. Each bridge floor drainage device comprises a drainage hole; a water grate frame arranged on the drainage hole, wherein the lower part of the water grate frame is provided with a step portion extending inwards from the inner periphery; a filter screen mounted on the step portion; and a water grate cover which is arranged on the water grate frame and used for capping the drainage hole, and is slightly lower than the adjacent bridge floor. By employing the drainage devices, water can be drained smoothly and slit can be filtered. The bridge floor drainage devices are easy to mount and dismount and are not easy to rust.
Description
Technical field
The utility model relates to a kind of bridge deck drainage device, especially for the dewatering installation of the bridge deck drainage of giving viaduct.
Background technology
Along with the urban traffic pressure is more and more come, building of viaduct is more and more general, and thing followed viaduct drainage problem also becomes and becomes more and more important.Especially in rainy season, heavy rain time particularly, keep the unobstructed of bridge floor, very important for the safety of bridge self and the safety of driving, if draining is obstructed, then bridge floor can cause ponding, and especially in the situation that ponding is excessively dark, vehicle probably casts anchor even causes more serious damage.In addition, ponding is trapped on the bridge floor, and the load that also can cause bridge to tolerate becomes large, and this has affected the safety of bridge.
Traditional viaduct dewatering installation normally arranges drain hole in the bridge floor both sides; shutter grate is placed on above the drain hole; these drain holes and shutter grate are normally formed by cast iron; during long-term the use, cause getting rusty, and because shutter grate is substantially to flush with bridge floor; and be unfavorable for that water flows out from drain hole; if and had mud, usually could stop up drain hole, and install and clean also inconvenient.
The utility model content
For problems of the prior art, the purpose of this utility model provides a kind of dewatering installation for viaduct, it is easy to make water to concentrate and flows in order to flow out smoothly from this dewatering installation, is not easy to produce ponding, can filters silt and installation and removal convenience.
The utility model provides a kind of bridge deck drainage device, and this bridge deck drainage device is arranged in the preformed hole of bridge both sides, it is characterized in that, this bridge deck drainage device comprises: drain hole; Be arranged on the shutter grate framework on the drain hole, described shutter grate framework bottom has the stage portion of inwardly stretching out from interior week; Screen pack, described screen pack are installed on this stage portion; And be arranged on the shutter grate framework shutter grate lid that is used for the described drain hole of capping; Described shutter grate lid is a little less than the adjacency bridge floor.
Wherein, on the described drain hole water conservancy diversion flange that carries out water conservancy diversion by the inclined-plane is installed.
Wherein, the upper surface of described shutter grate lid has diversion groove, and the periphery of this diversion groove is the inclined-plane.
Wherein, the external surface of described drain hole, shutter grate framework and shutter grate lid is coated with waterproofing course.
Wherein, described preformed hole is with the predetermined bridge both sides that are disposed on.
Wherein, described preformed hole top is rectangular opening, and the bottom is circular hole, and the diameter of circular hole is less than the rectangle length of short sides.
Wherein, the water conservancy diversion flange of described drain hole upper end and described shutter grate lid is shaped as the rectangle consistent with the rectangular opening on described preformed hole top.
By bridge deck drainage device recited above, swimmingly draining, and can filter silt, be easy to mount and dismount and be difficult for getting rusty.
Description of drawings
Fig. 1 is installed in the schematic configuration diagram of the bridge deck drainage device on the bridge;
Fig. 2 is the schematic diagram of shutter grate lid; And
Fig. 3 is drainage hole structure figure, and wherein Fig. 3 (a) is top view, and Fig. 3 (b) is the A-A sectional view.
The specific embodiment
Below, will specifically describe embodiment of the present utility model.
Bridge drain system of the present utility model is arranged in the preformed hole of bridge both sides, comprising: drain hole 2; Be arranged on the shutter grate framework 4 on the drain hole, described shutter grate framework bottom has the stage portion of inwardly stretching out from interior week; Screen pack 3, described screen pack are installed on this stage portion; And be arranged on the shutter grate framework shutter grate lid 1 that is used for the described drain hole of capping; Described shutter grate lid is a little less than the adjacency bridge floor.
Shown in Fig. 1 and 3 (a), Fig. 3 (b), described drain hole 2 bottoms are hollow cylinder holes, the upper end is equipped with diameter greater than hollow cylinder diameter and the rectangular flange concentric with hollow cylinder, this rectangular flange links to each other with cylinder via the inclined-plane and a little more than cylinder, thereby be easy to make water to flow towards cylinder, played the effect of water conservancy diversion.Shutter grate framework 4 is above preformed hole inside is arranged on described drain hole 2, and the bottom of this shutter grate framework 4 is useful on places superincumbent stage portion with screen pack, thereby can be easily with installation and removal screen pack 3, so that be convenient to clean.Shutter grate lid 1 shown in Figure 2 is placed on the shutter grate framework 4, because the upper end formation of this shutter grate lid 1 is by diversion groove, so the ponding of bridge floor easily flows into to this dewatering installation.
In the present embodiment, applied one deck waterproof coating at the external surface of drain hole 2, shutter grate framework 4 and shutter grate lid 1, thereby even the long-time use of dewatering installation of the present utility model also is difficult for getting rusty.
As shown in Figure 1, bridge deck drainage device of the present utility model can be arranged between the sidewalk 5 and runway 6 of bridge floor, and be positioned at guardrail foundation stone 7 inboards.
Above embodiment only is for the utility model clearly is described, and is not be used to limiting scope of the present utility model.Any modification and improvement that does not break away from spirit of the present utility model and essence must be considered as being encompassed in the scope of the present utility model.For example, although the preformed hole top among the embodiment is rectangular opening, also can be cylindrical hole, and the appropriate section of the drain hole that cooperates with this hole, shutter grate lid and shutter grate framework suitably be revised as cylindrical getting final product.
