However, in actual use, the drainage problem of highway bridges has become a difficult problem that needs to be solved urgently.

[0003] Traditional bridge drainage structures usually adopt a single-sided drainage ditch design, which has certain limitations in drainage efficiency. When encountering extreme weather conditions such as heavy rain or rainstorms, the drainage capacity of the single-sided drainage ditch often cannot meet actual needs, resulting in serious waterlogging on the bridge and even traffic accidents. Utility Model Content

[0006] Furthermore, the drainage ditch is provided with a plurality of ditch cover plates distributed along the length direction thereof, and each ditch cover plate is provided with a plurality of through grooves for water to enter the drainage ditch.

[0007] Furthermore, the drainage pipe is provided with a plurality of hoops distributed along its length direction, and the hoops are fixed to the bridge plate through connecting ribs.

[0008] Furthermore, floor drains are installed at the openings of the drainage holes.

[0009] Furthermore, the length of all drainage holes is half of the overall length of the bridge deck.

[0010] Furthermore, the drainage pipe is made of plastic.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model arranges the bottom of the drainage ditch to be a slope shape with high center and low sides, so as to promote the flow of water and simultaneously divide the water to the two sides, and then shares a part of the drainage of the drainage ditch through the drainage pipe, thereby improving the drainage efficiency of the drainage ditch as a whole.

[0019] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0020] Example

[0021] A high-speed bridge drainage structure described in this embodiment, such as Figures 1 to 5 As shown, the bridge comprises a bridge deck 1, and the bridge is composed of piers, abutments, and bridge decks 1. The left and right sides of the bridge deck 1 are provided with drainage ditches 3. During the construction of the bridge, several bridge decks 1 are connected and built. The bridge deck 1 is a prefabricated part. The drainage ditches 3 exist during the pouring of the bridge deck 1. The heights of the two ends of the bottom of the drainage ditch 3 are lower than the height of the middle. After all the bridge decks 1 are spliced ​​and the bridge is built, the bottom of the drainage ditch 3 is filled with cement. In this process, the height of the bottom of the drainage ditch 3 in the middle of the bridge deck 1 is higher than the height of the two ends. The purpose is to form a certain slope at the bottom of the drainage ditch 3. When draining water, the water flow is promoted, and it flows from the middle to the two ends of the bridge deck 1, so as to avoid all rainwater flowing in one direction and increasing the burden of the drainage ditch 3. Once a rainstorm occurs, the drainage ditch 3 may not meet the use requirements. Therefore, this diversion method is used to reduce the burden of the drainage ditch 3 and improve the drainage efficiency.

[0022] The drainage ditch 3 is provided with a plurality of ditch covers 4 distributed along its length direction, and each ditch cover 4 is provided with a plurality of through grooves for water to enter the drainage ditch 3; rainwater enters the drainage ditch 3 through the through holes on the ditch cover 4, and the through grooves can filter larger objects and prevent foreign objects from entering the drainage ditch 3 and causing blockage.

[0023] Drain pipes 2 distributed along the length direction are installed on the left and right sides of the bridge deck 1. The drain pipes 2 are made of plastic material, including polyethylene or polypropylene, which is light and easy to install by construction workers; the drain pipes 2 are provided with a plurality of clamps 7 distributed along the length direction, and the clamps 7 are fixed to the bridge deck 1 through connecting ribs; the clamps 7 are existing products, which are composed of two semicircular half-hoops, of which the half-hoops located on the upper side are fixed with the connecting ribs, and after the connecting ribs are fixed to the bridge deck 1, the two half-hoops are connected to each other to form a complete ring to fix the drain pipes 2 together; one drain pipe 2 needs to be fixed by a plurality of clamps 7.

[0024] Installation of connecting ribs: During pouring, threaded sleeves are embedded on both sides of the bridge deck 1, and external threads that are threadedly matched with the threaded sleeves are provided at the upper ends of the connecting ribs. The connecting ribs are fixed to the bridge deck 1 through threads.

[0025] The height of the two ends of the drain pipe 2 is lower than the height of the middle part. The drain pipe 2 is straight during production. When installed, it is slightly tilted to make it produce a certain curvature by using its own plasticity to promote the flow of water. A number of drainage holes are opened in the middle of the drainage ditch 3. The length of all drainage holes is half of the overall length of the bridge 1. Corresponding to each drainage hole, a connecting pipe 6 is connected to the outer wall of the drain pipe 2. The connecting pipe 6 is connected to the lower hole of the drainage hole and communicates with it. When the water flow in the drainage ditch 3 is too large, a part of it flows along the drainage hole through the connecting pipe 6 into the drainage pipe 2. The drainage pipe 2 shares part of the drainage of the drainage ditch 3, reducing its drainage burden and further improving the drainage efficiency.

[0026] A floor drain 5 is installed at the opening of the drainage hole; the inside of the drainage pipe 2 is not convenient for maintenance, so a floor drain is added at the drainage hole to further filter foreign matter entering the drainage ditch 3 to prevent foreign matter from entering the drainage pipe 2 and causing blockage.

[0027] During actual use: the bottom of the drainage ditch 3 is set to be a slope with a high middle and low ends, which promotes the flow of water and diverts the drainage to both sides, reduces the burden of unilateral drainage, and improves its drainage efficiency. A part of the rainwater in the drainage ditch 3 enters the drainage pipe 2 through the drainage hole and is shared by the drainage pipe 2, thereby having high drainage efficiency and reducing the risk of blockage.
