[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] The present application provides a flat-top trough drainage slope structure for a railway box-shaped bridge, which is mainly used to solve the problem that impurities such as leaves and soil carried in rainwater will accumulate inside the drainage trough, affecting the drainage effect, and requiring frequent manual cleaning to ensure smooth drainage. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0024] The flat-top trough-type drainage slope structure of a railway box-type bridge mainly includes a box-type bridge body 1. The top of the box-type bridge body 1 is constructed with a plurality of drainage grooves 2 distributed in an array. The drainage grooves 2 are installed on the top of the box-type bridge body 1 by mold casting. The depth and width of the drainage grooves 2 are designed according to the expected rainfall and drainage requirements to ensure sufficient drainage capacity. The array distribution of the drainage grooves 2 is achieved through precise measurement and positioning to ensure uniform distribution. The array-distributed drainage grooves 2 can more effectively collect and guide rainwater, reduce water on the bridge surface, and improve driving safety. At the same time, this design helps to reduce the erosion of the bridge structure by rainwater and extend the service life of the bridge. The inner wall of the drainage groove 2 is coated with a super-hydrophobic coating. The super-hydrophobic coating It can significantly reduce the adhesion of water on the surface, so that water droplets roll quickly and take away dirt when they contact the surface, reducing the frequency of maintenance. In addition, the chemical corrosion resistance of the coating helps to protect the bridge structure from damage by environmental factors. The two ends of the drainage trough 2 pass through the two sides of the box-shaped bridge body 1. Collection boxes 3 are installed on the opposite sides of the box-shaped bridge body 1. The collection box 3 corresponds to one end of the drainage trough 2. A filter screen 4 is arranged inside the collection box 3. The bottom of the collection box 3 is connected to a drainage pipe 5. The combination of the collection box 3 and the filter screen 4 can effectively collect impurities such as leaves carried in rainwater, facilitate subsequent collection, protect the environment from being clean, and prevent impurities from entering the drainage system, reducing the risk of blockage of the drainage pipe 5, and ensuring the smooth flow of the drainage system.

[0025] For further information, see Figure 2 A guide block 21 is embedded in the inner wall of the drainage trough 2. The longitudinal section of the guide block 21 is an isosceles triangle, and the two opposite ends of the guide block 21 correspond to the two ends of the drainage trough 2 respectively. The guide block 21 is made of the same material as the drainage trough 2, and is ensured to correspond to the two ends of the drainage trough 2 through precise cutting and installation. The design of the guide block 21 helps to improve the dynamic characteristics of the water flow, accelerate the water flow speed, and improve the drainage efficiency.

[0026] Specifically, the super-hydrophobic coating is coated on the two inclined sides of the guide block 21 and the side walls of the drainage groove 2. The combination of the inclined sides of the guide block 21 and the super-hydrophobic coating further enhances the self-cleaning effect and prevents impurities from accumulating inside the drainage groove 2 and affecting the drainage effect.

[0027] In this embodiment, the super-hydrophobic coating is a silica-silicone resin composite coating, which is evenly coated on the inner wall of the gutter 2 and the inclined side of the guide block 21 by spraying. The super-hydrophobic coating can significantly reduce the adhesion of water on the surface, allowing water droplets to roll quickly and carry away dirt when contacting the surface, reducing maintenance frequency. In addition, the chemical corrosion resistance of the coating helps to protect the bridge structure from damage by environmental factors.

[0028] For further information, see Figure 2 and Figure 3 A drain port 31 is provided on one side of the collection box 3 facing away from the box-shaped bridge body 1. The drain port 31 is located above the filter screen 4. When encountering heavy rain, impurities will block the filter holes on the filter screen 4, affecting the normal discharge of rainwater. The design of the drain port 31 helps to achieve rapid discharge of rainwater, reduce the water pressure in the collection box 3, and avoid damage to the collection box 3 due to excessive water pressure.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
