Description

Bridge rain drainage structure

Technical field

The utility model relates to the structural scheme field of bridge engineering, specifically a kind of bridge rain drainage structure.

Background technology

Highway bridge bridge floor both sides are interval with gutter, and general gutter is located at bottom anti-collision wall, and lower than bridge floor or identical with floor elevation at the bottom of pipe, gutter is no longer separately established in bridge floor both sides, and bridge beam body frange plate top is concordant with bridge floor.But because construction control is not tight, gutter is many higher than bridge floor, causes rainwater not get rid of in time.Further, as less in bridge longitudinal grade time, after heavy rain, bridge floor has ponding more, when vehicle high-speed is advanced, because of ponding buoyancy, direction of traffic be difficult to control, there is major accident hidden danger.

Therefore, needing one can get rid of bridge floor rainwater in time, avoid bridge floor ponding, is the bridge rain drainage structure eliminating driving accident hidden danger in rainy season.

Utility model content

In view of this, the purpose of this utility model is solution highway bridge bridge floor ponding in existing rainy season, eliminates driving accident hidden danger, provides a kind of new bridge rain drainage structure.

A kind of bridge rain drainage structure of the present utility model, frange plate and the drain structure in the described beam body both lateral sides face that comprises beam body, is covered in the bridge floor of beam body upper surface, is fixed on, described frange plate outer end is fixed with anti-collision wall; Described drain structure comprises and is arranged at gutter between bridge floor and anti-collision wall and the gutter for being discharged by rainwater in gutter;

Further, described gutter comprises the multiple transverse pipe be embedded in advance in described anti-collision wall and the longitudinal pipe connecting each transverse pipe outer end;

Further, below described beam body, be provided with land drain, described gutter also comprise be communicated with described longitudinal pipe and land drain vertical duct;

Further, described transverse drain outer end is lower than its inner setting;

Further, described drain structure also comprises ditch lamina tecti for hiding gutter and this ditch lamina tecti is infiltration hollow out concrete slab;

Further, described beam body is supported by bridge pier, and described vertical duct is arranged along bridge pier.

The beneficial effects of the utility model are: bridge rain drainage structure of the present utility model, in beam body both sides, gutter is set, this gutter take frange plate as bottom surface, with anti-collision wall and bridge floor for side wall, and then make full use of existing bridge engineering girder construction system, former beam body frange plate end face absolute altitude is reduced the ditch bottom surface of 10-20cm as draining lateral sulcus, increase former anti-collision wall height, as the side wall of draining lateral sulcus, ensure that the rainwater that bridge floor gathers can flow in gutter, avoid bridge floor ponding, thus eliminate driving accident hidden danger in rainy season.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further described:

Fig. 1 is beam body section structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the partial enlarged drawing at A place in Fig. 1.

Detailed description of the invention

As shown in Figure 1 and Figure 2, the bridge rain drainage structure of the present embodiment, frange plate 6 and the drain structure 3 in the described beam body 5 both lateral sides face that comprises beam body 5, is covered in the bridge floor 2 of beam body 5 upper surface, is fixed on, described frange plate 6 outer end is fixed with anti-collision wall 1, described drain structure 3 comprises and is arranged at the gutter 8 between bridge floor 2 and anti-collision wall 1 and the gutter for being discharged by rainwater in gutter 8, in beam body 5 both sides, gutter 8 is set, this gutter 8 with frange plate 6 for bottom surface, with anti-collision wall 1 and bridge floor 2 for side wall, and then make full use of existing bridge engineering beam body 5 structural system, former beam body 5 frange plate 6 end face absolute altitude is reduced the ditch bottom surface of 10-20cm as draining lateral sulcus, increase former anti-collision wall 1 height, as the side wall of draining lateral sulcus, ensure that the rainwater that bridge floor 2 gathers can flow in gutter 8, avoid bridge floor 2 ponding, thus eliminate driving accident hidden danger in rainy season.

In the present embodiment, described gutter comprises the multiple transverse pipe 4 be embedded in advance in described anti-collision wall 1 and the longitudinal pipe 9 connecting each transverse pipe 4 outer end, the rainwater accumulated in gutter 8 flows out through each transverse pipe 4 and comes together in longitudinal pipe 9, by this longitudinal pipe 9, rainwater is being led to appropriate area, avoid rainwater directly to flow down from beam body 5, cause road surface or building below bridge to be subject to sewage and wash away.

In the present embodiment, land drain 8 is provided with below described beam body 5, described gutter also comprise be communicated with described longitudinal pipe 9 and land drain 8 vertical duct 10, rainwater can be led in gutter 8 by this vertical duct 10, be delivered in Urban Underground grid by gutter 8 again, avoid bridge periphery to be subject to sewage pollution.

In the present embodiment, described transverse drain outer end, lower than its inner setting, ensures that the rainwater in gutter 8 can lean on self gravitation to flow out from high to low.

In the present embodiment, described drain structure 3 also comprises the ditch lamina tecti 7 for hiding gutter 8 and this ditch lamina tecti 7 is infiltration hollow out concrete slab, ditch lamina tecti 7 can avoid the impurity on bridge floor 2 to enter in gutter 8, blocking gutter, pedestrian can be avoided again accidentally to fall in gutter 8 on the other hand, infiltration hollow out concrete slab has higher intensity, can filter out larger impurity simultaneously and enter in gutter 8.

In the present embodiment, described beam body 5 is supported by bridge pier 11, and described vertical duct 10 is arranged along bridge pier 11, can the multiple fixed point of relative set utilize the existing pipe fixing devices such as anchor ear to be fixed by vertical duct 10 on bridge pier 11.

What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
