Description

Technical Field

[0001] The present invention belongs to the technical field of roadbed drainage, and in particular relates to a highway roadbed drainage device for coping with extreme rainstorm conditions. Background Art

[0002] The roadbed is the foundation of a track or road surface, a geotechnical structure formed through excavation or filling. Its primary function is to provide the necessary conditions for track or road paving and train or vehicle operations, and to withstand the static and dynamic loads of the track and rolling stock, or the road surface and traffic, making it a crucial structural component of highways. To ensure roadbed stability, drainage systems are required to remove water from the roadbed, preventing it from soaking, saturating, and eroding the roadbed soil, potentially destabilizing and weakening the roadbed. This is especially true during extreme rainstorms, when large amounts of rainwater accumulate and require rapid drainage. However, existing roadbed drainage systems are unable to cope with these extreme conditions. Summary of the Invention

[0003] In view of this, the present invention discloses a highway roadbed drainage device for coping with extreme rainstorm conditions, which aims to solve the problem that existing roadbed drainage devices are unable to cope with extreme rainstorm environments.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A highway roadbed drainage device for coping with extreme rainstorm conditions includes a roadbed, a plurality of drainage grooves vertically arranged in the roadbed, a drainage pipe arranged in the drainage grooves, a filter plate arranged at the top of the drainage pipe, an annular groove coaxial with the drainage pipe is arranged in the roadbed, an annular accumulation pipe is coaxially arranged at the bottom of the annular groove, the accumulation pipe is connected to the annular groove, a sealing block is vertically slidingly arranged in the annular groove, and a driving structure for driving the sealing block to move is arranged at the top of the annular groove; a plurality of upper connecting pipes connected to the drainage pipe and inclined upward are arranged at the upper end of the accumulation pipe, and a plurality of lower connecting pipes connected to the drainage pipe and inclined downward are arranged at the lower end of the accumulation pipe; a closing structure for closing the pipe openings of the upper and lower connecting pipes is provided in the drainage pipe.

[0006] In this solution, under extreme rainstorm conditions, when a large amount of rainwater accumulates, the closing structure is used to close the pipe mouth of the lower connecting pipe. At this time, the driving structure drives the sealing plate to move upward, thereby reducing the pressure in the accumulation pipe and the annular groove, sucking the top area of ​​the drainage pipe, and accelerating the water inlet efficiency of the drainage pipe; when the driving structure drives the sealing block to move downward, the closing structure opens the pipe mouth of the lower connecting pipe and closes the pipe mouth of the upper connecting pipe, thereby increasing the pressure in the accumulation pipe and the annular groove, and then the water in the accumulation pipe and the annular groove is quickly discharged to the bottom area of ​​the drainage pipe; repeating the above operations can effectively speed up the water inlet and drainage efficiency of the drainage device, and avoid large amounts of rainwater accumulation in extreme rainstorm environments, which affects the stability of the roadbed.

[0007] Furthermore, the closed structure includes a support shaft fixed to the bottom of the filter plate, an annular seat is coaxially slidably connected to the support shaft, and a power structure for driving the annular seat to slide is provided at the bottom of the filter plate; the closed structure also includes an annular baffle, the length of the baffle is greater than the distance between the pipe openings of the lower connecting pipe and the upper connecting pipe, and a support rod is provided between the baffle and the annular seat.

[0008] In this solution, the power structure is used to push the annular seat to move vertically, and the annular seat drives the baffle to move vertically synchronously, so as to ensure that the opening of the other connecting pipe is unobstructed while closing the lower connecting pipe or the upper connecting pipe.

[0009] Furthermore, the filter plate is provided with a plurality of water-permeable grooves distributed in a circular array toward its center, a slide seat is provided in the water-permeable groove, and slide grooves slidably connected to the slide seat are horizontally opened on both sides of the water-permeable groove, and a pushing structure for pushing away debris is provided on the slide seat; a plurality of connecting rods are hinged on the circumferential side of the annular seat, and the connecting rods are hinged to the corresponding slide seats.

[0010] Furthermore, the pushing structure includes two vertically arranged rotating shafts, each of which is provided with a number of push plates, and two vertical mounting holes for accommodating the rotating shafts are provided on the slide; grooves are provided on both sides of the slide, and drive gears are provided in the grooves, and the drive gears are vertically slidably sleeved on the corresponding rotating shafts, and tooth plates are provided on the side walls of the slide grooves to extend into the grooves and engage with the corresponding drive gears.

[0011] Furthermore, the rotating shaft is movably arranged in the mounting hole, the bottom of the rotating shaft is coaxially connected with a spherical block, elastic support members are fixed between the spherical block and the slide seat, and inclined plates are inclined at both ends of both sides of the water-permeable groove for contacting the upper end of the spherical block.

[0012] Furthermore, the rotating shaft and the top end of the push plate are both arc-shaped.

[0013] Furthermore, the rotating shaft and the push plate are both provided with a reflective coating.

DETAILED DESCRIPTION

[0021] As shown in the figure: Figures 1 to 4

[0022] A roadbed 1 drainage device for coping with extreme rainstorm conditions, comprising a roadbed 1, a plurality of drainage grooves vertically arranged in the roadbed 1, a drain pipe 2 arranged in the drainage groove, a filter plate 3 arranged at the top end of the drain pipe 2, an annular groove coaxial with the drain pipe 2 arranged in the roadbed 1, an annular storage pipe 4 coaxially arranged at the bottom of the annular groove, the storage pipe 4 being in communication with the annular groove, a sealing block 5 vertically and slidingly arranged in the annular groove, a driving structure 6 arranged at the top end of the annular groove for driving the sealing block 5 to move, the driving structure 6 in the embodiment being an electric telescopic rod, which is a conventional technical means and thus is not described in detail, an upper communication pipe 7 arranged at the upper end of the storage pipe 4 and in communication with the drain pipe 2 and inclined upward, a lower communication pipe 8 arranged at the lower end of the storage pipe 4 and in communication with the drain pipe 2 and inclined downward, and a closing structure arranged in the drain pipe 2 for closing the pipe openings of the upper and lower communication pipes 7 and 8.

[0023] ​In this solution, under extreme rainstorm conditions, when a large amount of rainwater accumulates, the closing structure is used to close the mouth of the lower connecting pipe 8. At this time, the driving structure 6 drives the sealing plate to move upward, thereby reducing the pressure in the accumulation pipe 4 and the annular groove, sucking the top area of ​​the drainage pipe 2, and accelerating the water inlet efficiency of the drainage pipe 2; when the driving structure 6 drives the sealing block 5 to move downward, the closing structure opens the mouth of the lower connecting pipe 8 and closes the mouth of the upper connecting pipe 7, thereby increasing the pressure in the accumulation pipe 4 and the annular groove, and then the water in the accumulation pipe 4 and the annular groove is quickly discharged to the bottom area of ​​the drainage pipe 2; repeating the above operations can effectively speed up the water inlet and drainage efficiency of the drainage device, and can also avoid the accumulation of a large amount of rainwater in extreme rainstorm environments, which affects the stability of the roadbed 1.

[0024] In this embodiment, the closed structure includes a support shaft 9 welded and fixed to the bottom of the filter plate 3, and an annular seat 10 is coaxially slidably connected to the support shaft 9. A power structure 19 for driving the annular seat 10 to slide is provided at the bottom of the filter plate 3. The power structure 19 in this embodiment adopts an electric telescopic rod, which is a conventional technical means and is not elaborated in detail; the closed structure also includes an annular baffle 11, the length of the baffle 11 is greater than the distance between the pipe openings of the lower connecting pipe 8 and the upper connecting pipe 7, and a support rod 12 is provided between the baffle 11 and the annular seat 10.

[0025] In this solution, the power structure 19 is used to push the annular seat 10 to move vertically, and the annular seat 10 drives the baffle 11 to move vertically synchronously, so as to close the lower connecting pipe 8 or the upper connecting pipe 7 while ensuring that the other connecting pipe opening is unobstructed.

[0026] In this embodiment, a plurality of water-permeable grooves 13 are distributed in a circular array on the filter plate 3 toward its center, a slide 14 is provided in the water-permeable groove 13, and slide grooves slidably connected to the slide 14 are horizontally opened on both sides of the water-permeable groove 13. A pushing structure for pushing away debris is provided on the slide 14; a plurality of connecting rods 22 are hinged on the circumferential side of the annular seat 10, and the connecting rods 22 are hinged to the corresponding slides 14.

[0027] In this solution, when the power structure 19 pushes the annular seat 10 to move back and forth vertically, the annular seat 10 drives the slide 14 to move back and forth horizontally through the connecting rod 22, and utilizes the pushing structure on the annular seat 10 to push away the debris blocking the water-permeable groove 13, thereby avoiding affecting the water inlet efficiency of the water-permeable groove 13, and thus affecting the drainage efficiency of the drainage device.

[0028] In this embodiment, the pushing structure includes two vertically arranged rotating shafts 15, each of which is provided with a plurality of push plates 16, and two vertically provided mounting holes for accommodating the rotating shafts 15 are provided on the slide 14; grooves are provided on both sides of the slide 14, and drive gears 23 are provided in the grooves. The drive gears 23 are vertically slidably sleeved on the corresponding rotating shafts 15, and the side walls of the slide grooves are provided with tooth plates 20 that extend into the grooves and engage with the corresponding drive gears 23.

[0029] When the slide 14 moves, the tooth plate 20 drives the driving gear 23 to rotate, and the driving gear 23 drives the rotating shaft 15 to rotate synchronously. The rotating shaft 15 drives the pushing plate 16 to rotate, which exerts a greater force on the debris, making it easier to push away the debris and prevent the debris from clogging the water permeable groove 13.

[0030] In this embodiment, the rotating shaft 15 is movably arranged in the mounting hole, and the bottom of the rotating shaft 15 is coaxially connected to a spherical block 17. Elastic support members 18 are fixed between the spherical block 17 and the slide seat 14. Both ends of the two sides of the water-permeable groove 13 are inclinedly provided with inclined plates 21 for contacting the upper end of the spherical block 17.

[0031] In this solution, under normal conditions, the slide 14 is located at both ends of the water-permeable groove 13. At this time, the inclined plate 21 drives the rotating shaft 15 to move downward by squeezing the spherical block 17, so that the top ends of the rotating shaft 15 and the push plate 16 do not extend out of the water-permeable groove 13, thereby preventing the top ends of the rotating shaft 15 and the push plate 16 from affecting the safety of pedestrians and vehicles; in an extreme rainstorm environment, the slide 14 is driven by the annular seat 10 to move horizontally. When the spherical block 17 is separated from the inclined plate 21, the elastic support member 18 pushes the rotating shaft 15 upward through the spherical block 17, so that the top ends of the rotating shaft 15 and the push plate 16 extend out of the water-permeable groove 13 to clear debris; at the same time, when pedestrians and vehicles step on the top end of the rotating shaft 15, the elasticity of the elastic support member 18 can make the rotating shaft 15 and the push plate 16 slide into the water-permeable groove 13, thereby reducing the risk of pedestrians and vehicles stepping on the drainage device.

[0032] In this embodiment, the top ends of the rotating shaft 15 and the pushing plate 16 are both arc-shaped.

[0033] The top ends of the rotating shaft 15 and the push plate 16 are arranged in an arc shape to further reduce the danger posed by the drainage device to pedestrians and vehicles.

[0034] In this embodiment, both the rotating shaft 15 and the push plate 16 are provided with a reflective coating.

[0035] A reflective coating is provided on the rotating shaft 15 and the push plate 16 to facilitate prompting pedestrians and vehicles and reduce contact with the drainage device.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
