Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge drainage structure. Background Art
[0002] In the development and construction of urban transportation, bridge drainage construction is a very important project. Once water accumulates on the bridge deck on rainy days, the tires of vehicles traveling at high speeds on it will be affected by the water and slip, lose control, and cause serious traffic accidents such as vehicle sliding or rollover. Therefore, the drainage facilities on the bridge deck of highways are important projects. At present, for bridge deck drainage, multiple PVC drainage pipes are usually connected to the slope of the bridge. The drainage pipes are led down along the bridge to drain the rainwater on the bridge deck to the urban drainage network. However, fine sand and silt are easily retained on the edge of the bridge, which requires regular cleaning by sanitation workers, which is relatively cumbersome. Utility Model Content

[0007] Preferably, the diversion ramp is inclined downward toward the diversion hole.
[0008] Preferably, the inclination angle of the diversion ramp is 10°-35°.
[0009] Preferably, the drainage trough and the diversion ramp are cast in one piece.

[0011] Preferably, the outer sides of the two groups of arc-shaped guide plates are sleeved with clamps.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model reserves drainage grooves at the edges of the bridge on both sides of each box girder bridge deck, and rainwater flows along the bridge deck to the drainage grooves on both sides of the bridge. By utilizing two sets of diversion ramps obliquely arranged in the drainage grooves, rainwater can flow into the diversion holes along the diversion ramps. Moreover, due to the inclined diversion ramps, rainwater washes fine sand, soil, etc. and quickly flows down to the joint of the box beams under the action of its own gravity and the scouring of rainwater. The overall structural design is simple and the construction is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 3 It is a structural schematic diagram of a deflector cover and an arc-shaped deflector plate of the utility model.
[0018] The following are the descriptions of the reference numerals:
[0019] 1 is a drainage trough, 2 is a cover plate, 3 is an arc-shaped guide plate, 4 is a guide ramp, 5 is a guide hole, and 6 is a guide cover. DETAILED DESCRIPTION
[0020] The following is combined with Figure 1-3 , the technical solution of the utility model is further explained:
[0021] like Figure 1-Figure 3 As shown, a bridge drainage structure includes several box beams, and drainage grooves 1 are respectively provided on both sides of the box beams, and a cover plate 2 with through holes is detachably provided on the upper part of the drainage grooves 1. That is, a full-length drainage groove is reserved on the bridge deck at both sides of each box beam, and a cover plate is provided on the drainage groove, and a plurality of through holes are evenly provided on the cover plate, so that rainwater can flow from the bridge deck through the through holes into the drainage groove.
[0022] Specifically, Figure 2 As shown, a first guide structure is arranged in the drainage trough 1, and guide holes 5 penetrating the box beam and connected to the first guide structure are respectively opened at both ends of the drainage trough 1. In other words, the first guide structure arranged in the drainage trough is connected to the guide hole, and rainwater flows into the drainage trough through the through hole and falls on the first guide structure, and then flows downward along the first guide structure to the guide hole.
[0023] In some embodiments, the first diversion structure includes two groups of symmetrically arranged diversion ramps 4, and the two groups of diversion ramps 4 are respectively connected to the corresponding diversion holes 5. That is to say, inclined diversion ramps are symmetrically arranged in the drainage trough of each section of the box girder, one end of the diversion ramp is connected to the diversion hole, and one end of the adjacent diversion ramp forms a diversion surface.
[0024] It should be noted that the drainage trough 1 and the diversion ramp 4 are cast in one piece.
[0025] In some embodiments, the diversion ramp 4 is inclined downward toward the diversion hole 5. That is, the diversion ramp is inclined downward toward the diversion hole, so that rainwater flows into the diversion hole along the diversion ramp.
[0026] It should be noted that the inclination angle of the diversion ramp 4 is 10°-35°. In this embodiment, the inclination angle of the diversion ramp is 30°.
[0027] Specifically, Figure 2 and Figure 3 As shown, a second guide structure is provided at the lower part of the guide hole 5, and the second guide structures corresponding to the two adjacent box beam sections form a vertical downward guide channel as a whole. In other words, the second guide structure provided at the lower part of the guide hole and the adjacent second guide structures form a vertical downward guide channel as a whole, and the rainwater flowing out of the guide hole can flow into the underground drainage network along the second guide structure.
[0028] In some embodiments, Figure 3 As shown, the second flow guide structure includes a flow guide cover 6 and an arc-shaped flow guide plate 3, wherein the flow guide cover 6 is fixedly arranged at the lower part of the flow guide hole 5, and the arc-shaped flow guide plate 3 is arranged at the lower part of the flow guide cover 6. The corresponding flow guide covers 6 and arc-shaped flow guide plates 3 between two adjacent sections of box girders are bonded, and two groups of the arc-shaped flow guide plates 3 form a flow guide channel. In other words, a flow guide cover is arranged below the flow guide hole, and an arc-shaped flow guide plate is integrated at the lower part of the flow guide cover. After the two adjacent sections of box girders are butt-jointed, the corresponding flow guide cover and the corresponding arc-shaped flow guide plate are bonded into a whole by high-strength adhesive, so that rainwater on the bridge deck of the two adjacent sections of box girders can flow into the drainage network through the flow guide channel at the junction. It should be noted that the size of the flow guide cover is larger than the width of the flow guide hole.
[0029] It should be noted that a clamp is sleeved on the outside of the two groups of arc-shaped guide plates 3. That is, in order to improve the connection stability between the two adjacent groups of arc-shaped guide plates, a reinforcement clamp is also sleeved on the outside of the two groups of arc-shaped guide plates.
[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
