Description

Technical Field

[0001] This invention relates to the field of highway culvert drainage technology, specifically to a highway culvert drainage structure and its construction method. Background Technology

[0002] As a key ancillary facility in highway engineering, culverts are mainly used to cross natural valleys and depressions to drain floodwaters, or as elevated passageways for people, livestock, and vehicles. Their drainage performance directly affects the safety and service life of highway traffic. The entrances of highway culverts are generally constructed in the form of a V-shaped wall or a straight wall.

[0003] For example, patent application number 202211171704.6 discloses a culvert anti-clogging drainage structure, which "includes a culvert body, a drainage ditch on one side of the culvert body, and grids for blocking debris at both ends of the drainage ditch. A cleaning component is installed on the grid for cleaning the upper surface of the grid. A sewage pump is installed inside the drainage ditch, and a flushing pipe and a drain pipe are connected at the output end of the sewage pump. The output end of the flushing pipe is located inside the drainage ditch, and the output end of the drain pipe is located outside the culvert body. A power mechanism is also installed inside the culvert body to drive the cleaning..." The components and sewage pump are in operation. This application has the effect of improving the problem of drainage ditches in culverts being easily blocked by silt. However, the culvert anti-blockage drainage structure disclosed in the above-mentioned literature still has the following disadvantages: the flushing pipe of the sewage pump can only flush the bottom of the drainage ditch, and the silt on the side walls and corners of the drainage ditch is difficult to flush away, which easily forms deposits and hardens, resulting in a reduction in the cross-section of the drainage ditch and a decrease in drainage capacity; the bar cleaning only relies on the horizontal sliding of the wire brush plate, which can only remove large debris on the surface of the bar, while the fine sand and silt particles stuck in the gaps of the bar cannot be effectively cleaned. Long-term accumulation can easily lead to blockage of the bar pores and affect the drainage flow. Summary of the Invention

A water outlet pipe 73 is located on one side of the water storage tank 72 and is installed inside the fixed rod 71. A high-pressure water pipe 74 is located in the middle of the fixed rod 71 and is installed inside the fixed rod 71 at both ends. The water outlet pipe 73 is installed inside the high-pressure water pipe 74 through the fixed rod 71. A first rotating water outlet ring 75 is provided on the outer wall of both ends of the high-pressure water pipe 74. A first high-pressure water outlet head 751 is provided on the outer wall of the first rotating water outlet ring 75. A first water outlet nozzle 752 is provided on both sides of the outer wall of the first high-pressure water outlet head 751.

After cleaning the water flow in front and the residue in this area, the cleaning effect in the main drainage ditch 7 is better and the stability is higher. The vibration of the screen body 5 by the vibration component 8 makes the water flow of the screen body 5 better and cleans the blockage of the screen body 5 better. When the water volume is large, the solenoid valve 25 is opened by the energy storage device 4 to allow the water to flow through. Water can flow out through the auxiliary drain pipe 22, making the drainage effect of the device better. When it is necessary to clean the inside of the main drainage ditch 7, the water storage tank 72 is opened by the energy storage device 4, so that the water flow is output to the inside of the high pressure water pipe 74 through the water outlet pipe 73. After the high pressure water pipe 74 is filled with water, the first rotating water outlet ring 75 is operated by the energy storage device 4. When the first rotating water outlet ring 75 is working, due to the tangential angle of the water outlet, the first rotating water outlet ring 75 is driven to rotate on the high pressure water pipe 74, so that the first high pressure water outlet head 751 and the first water outlet nozzle 752 can better clean the dirt inside the main drainage ditch 7.
