Abstract
The utility model discloses a drainage system of a high level bridge. The drainage system comprises a traffic lane, a pavement and kerbstones positioned between the traffic lane and the pavement, through holes allowing rain water to flow are formed on the kerbstones, and a catchment and drainage channel extending longitudinally along the pavement is arranged below the pavement and is connected with the through holes on the kerbstones. The drainage system of the high level bridge provided by the utility model has large catchment and drainage amount and high safety, and the drainage is not easy to block.
Description
Technical field
The utility model relates to a kind of bridge deck drainage structure, particularly relates to a kind of viaduct drainage system.
Background technology
The bridge deck drainage structure of tradition viaduct all adopts bridge floor collecting well, gutter, ground to collect this system of well usually, collecting well and gutter generally only are provided with at bridge pier, abutment place, like this, the bridge floor bleeding point of rainwater is less, collecting amount is less, and the caliber of gutter is less again, gutter is easily blocked by bigger foreign material, safeguards mediation inconvenience; In addition, the general outer outside that hangs over bridge pier structure of gutter, not only visually the utmost point is not attractive in appearance, in the high special location of some security requirements, for example stride the section of high ferro,, plug-in gutter is set wears out because of pipeline, come off, block and cause potential safety hazard because of crossing over the particularity in zone.
Therefore, those skilled in the art is consistent is devoted to develop a kind of catchment and bleeder quantity is big, draining is difficult for blocking, safe viaduct drainage system.
The utility model content
At the deficiency that above-mentioned prior art exists, the utility model provides a kind of and catchments and bleeder quantity is big, draining is difficult for blocking, safe viaduct drainage system.
To achieve these goals, the purpose of this utility model is to provide a kind of viaduct drainage system, described viaduct comprises runway, sidewalk and the kerbstone between runway and sidewalk, offer the through hole that flows into for rainwater on the described kerbstone, below, described sidewalk is provided with the drainage gallery that catchments along the sidewalk longitudinal extension, and the described drainage gallery that catchments is communicated with through hole on the described kerbstone.
Further, the below on described sidewalk is provided with at least one bearing beam, and described bearing beam is along the sidewalk longitudinal extension, forms the described drainage gallery that catchments between described kerbstone and the adjacent described bearing beam; Preferably, be coated with water-repellent paint on the inner surface of the described drainage gallery that catchments.
Further, the water conservancy diversion slope that has a down dip and arrange towards the drainage gallery that catchments is arranged in the through hole bottom surface on the described kerbstone, and rainwater is flowed in the drainage gallery that into catchments faster by the through hole of kerbstone.
Further, be provided with the trash rack that stops rubbish, foreign material to enter in the through hole on the described kerbstone.
Further, described sidewalk is obliquely installed along edge to being directed downwards of described kerbstone from described viaduct; Preferably, described sidewalk is 1% along the gradient that tilts to the direction of described kerbstone from the edge of described viaduct.
Further, described runway is obliquely installed along bridge floor center line to being directed downwards of described kerbstone from described viaduct; Preferably, described runway is 2% along bridge floor center line to the gradient that described kerbstone direction tilts from described viaduct.
Further, the gutter on the outer road surface of described catchment drainage gallery and the abutment that is arranged at described viaduct is communicated with.
Compared with prior art, the utlity model has following advantage:
1. cancelled bridge floor collecting well and gutter, made full use of collection and the drainage gallery of the clearance spaces of below, sidewalk as the bridge floor rainwater.
2. the bridge floor rainwater is collected to change into along the bridge floor sidewalk by the point-like at original bridge pier place and is vertically collected completely, catchments and bleeder quantity improves greatly, and water vent is difficult for blocking.
3. cancel the plug-in gutter at each bridge pier place, only be arranged on the outer road surface of abutment, increased the aesthetic property of the outer facade of elevated bridge; Simultaneously, avoided the bridge pier place that the potential safety hazard that plug-in gutter brings is set, be suitable for the high high ferro section of striding of security requirement is used.
4. safeguard that maintenance is more convenient, the drainage gallery that catchments only need remove covering sidewalk cover plate thereon and both can safeguard.
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is a cross-sectional view of the present utility model.
The specific embodiment
Fig. 1 and Fig. 2 have shown a preferred embodiment of viaduct drainage system of the present utility model.Viaduct comprises sidewalk 1, runway 2 and the kerbstone 4 between sidewalk 1 and runway 2.Offer the through hole 41 that flows into for rainwater on the kerbstone 4,1 below, sidewalk is provided with the drainage gallery 6 that catchments of 1 longitudinal extension along the sidewalk, and the drainage gallery 6 that catchments is communicated with through hole 41 on the kerbstone 4.In a specific embodiment, the water conservancy diversion slope 7 that tilts towards the drainage gallery 6 of catchmenting is arranged in the bottom surface of the through hole 41 on the kerbstone 4, and the rainwater that is beneficial to flow into through hole 41 flow to the drainage gallery 6 that catchments fast.In a specific embodiment, be furnished with trash rack 5 in the through hole 41 of kerbstone 4, enter into the drainage gallery 6 that catchments to stop rubbish, foreign material.
Be provided with bearing beam 3 below sidewalk 1, bearing beam 3 is 1 longitudinal extension along the sidewalk, forms the drainage gallery 6 that catchments between kerbstone 4 and the adjacent bearing beam 3.In a specific embodiment, be coated with the water-repellent paint layer 8 that prevents that rainwater from oozing out on the inner surface of the drainage gallery 6 that catchments.
Sidewalk 1 along from the edge of viaduct to the inclination that is directed downwards of kerbstone 4.In the present embodiment, the gradient on sidewalk 1 is 1%.
Runway 2 is along the inclination that is directed downwards to kerbstone 4 from the bridge floor center line of viaduct.In the present embodiment, the gradient of runway 2 is 2%.
The gutter that catchments on the outer road surface of drainage gallery 6 and the abutment that is arranged at viaduct is communicated with (not shown).
In specific embodiment, the road surface on sidewalk 1 is to be spliced by the sidewalk cover plate 11 that polylith is covered on the drainage gallery 6 that catchments.
More than describe preferred embodiment of the present utility model in detail.The ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
