Description

Technical Field

[0001] The 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 the track or road surface, and is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track and locomotive vehicles or road surface and traffic loads. It is an important component structure of the highway. In order to ensure the stability of the roadbed, a drainage device needs to be set up to drain the water on the roadbed to prevent the water from soaking, saturating and eroding the roadbed soil, causing the roadbed to lose stability and strength; especially under extreme rainstorm conditions, a large amount of rainwater accumulates and needs to be drained quickly, but the existing roadbed drainage device cannot cope with extreme rainstorm environments. 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 the existing roadbed drainage device cannot cope with the extreme rainstorm environment.

[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 arranged in the roadbed, an annular accumulation pipe coaxially arranged at the bottom of the annular groove, the accumulation pipe is connected to the annular groove, a sealing block is vertically slidably arranged in the annular groove, and a driving structure for driving the sealing plate 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 arranged in the drainage pipe.

[0006] In this solution, under extreme rainstorm conditions, when a large amount of rainwater accumulates, the opening of the lower connecting pipe is closed by a closing structure. At this time, the sealing plate is driven upward by the driving structure to reduce the pressure in the accumulation pipe and the annular groove, and the top area of ​​the drainage pipe is sucked to speed up the water inlet efficiency of the drainage pipe. When the driving structure drives the sealing plate to move downward, the closing structure opens the opening of the lower connecting pipe and closes the opening of the upper connecting pipe, so that the pressure in the accumulation pipe and the annular groove is increased, and 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 can also 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 which is greater than the distance between the lower connecting tube and the upper connecting tube orifices, 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 that the lower connecting pipe or the upper connecting pipe can be closed while ensuring that the other connecting pipe is unobstructed.

[0009] Furthermore, a plurality of water-permeable grooves are distributed in a circular array on the filter plate toward the center thereof, a sliding seat is arranged in the water-permeable groove, and sliding grooves slidably connected to the sliding seat are horizontally opened on both sides of the water-permeable groove, and a pushing structure for pushing away debris is arranged on the sliding 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 sliding seats.

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

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

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

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

DETAILED DESCRIPTION

[0021] like Figures 1 to 4 As shown:

[0022] A highway roadbed drainage device 1 for coping with extreme rainstorm conditions comprises a roadbed 1, wherein the roadbed 1 is vertically provided with a plurality of drainage grooves, wherein a drainage pipe 2 is provided in the drainage groove, a filter plate 3 is provided at the top of the drainage pipe 2, an annular groove coaxial with the drainage pipe 2 is provided in the roadbed 1, an annular accumulation pipe 4 coaxially provided at the bottom of the annular groove, the accumulation pipe 4 is connected with the annular groove, a sealing block 5 is vertically slidably provided in the annular groove, a driving structure 6 for driving the sealing plate to move is provided at the top of the annular groove, and the driving structure 6 in this embodiment adopts an electric telescopic rod, which belongs to conventional technical means, so it is not elaborated in detail; a plurality of upper connecting pipes 7 connected with the drainage pipe 2 and inclined upward are provided at the upper end of the accumulation pipe 4, and a plurality of lower connecting pipes 8 connected with the drainage pipe 2 and inclined downward are provided at the lower end of the accumulation pipe 4; a closing structure for closing the pipe openings of the upper connecting pipes 7 and the lower connecting pipes 8 is provided in the drainage pipe 2.

[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 drain pipe 2, and accelerating the water inlet efficiency of the drain pipe 2; when the driving structure 6 drives the sealing plate 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, so that the pressure in the accumulation pipe 4 and the annular groove is increased, and the water in the accumulation pipe 4 and the annular groove is quickly discharged to the bottom area of ​​the drain pipe 2; repeating the above operation can effectively accelerate the water inlet and drainage efficiency of the drainage device, and can also avoid large amounts of rainwater accumulation 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 belongs to 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 tube 8 and the upper connecting tube 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 that the lower connecting pipe 8 or the upper connecting pipe 7 can be closed 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 the center thereof, a slide seat 14 is arranged in the water-permeable groove 13, and slide grooves slidably connected to the slide seat 14 are horizontally opened on both sides of the water-permeable groove 13, and a pushing structure for pushing away debris is arranged on the slide seat 14; a plurality of connecting rods 22 are hinged on the peripheral side of the annular seat 10, and the connecting rods 22 are hinged to the corresponding slide seats 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 sliding seat 14 to move back and forth horizontally through the connecting rod 22, and the pushing structure on the annular seat 10 is used to push away the debris blocking the water-permeable groove 13, so as to avoid affecting the water inlet efficiency of the water-permeable groove 13, thereby 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 the slide seat 14 is provided with two vertically arranged mounting holes for accommodating the rotating shafts 15; grooves are provided on both sides of the slide seat 14, each of which is provided with a driving gear 23, and the driving gear 23 is vertically slidably sleeved on the corresponding rotating shaft 15, and the side walls of the slide groove are provided with a tooth plate 20 that extends into the groove and meshes with the corresponding driving gear 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 to exert a greater force on the debris, which can more easily 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 rotatably connected with a spherical block 17, and an elastic support member 18 is fixed between the spherical block 17 and the slide seat 14, and both ends of both sides of the water-permeable groove 13 are inclinedly arranged with an inclined plate 21 for contacting the upper end of the arc block.

[0031] In this scheme, 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 are both extended 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 away debris. At the same time, when pedestrians and vehicles step on the top of the rotating shaft 15, the elasticity of the elastic support member 18 can be used to 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 rotating shaft 15 and the top end of the baffle 11 are both arc-shaped.

[0033] The rotating shaft 15 and the top end of the baffle 11 are arranged in an arc shape, so as to further reduce the danger of the drainage device to pedestrians and vehicles.

[0034] In this embodiment, both the rotating shaft 15 and the baffle 11 are provided with a reflective coating.

[0035] A reflective coating is provided on the rotating shaft 15 and the baffle 11 to facilitate the reminder of pedestrians and vehicles and reduce the 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 rather than to limit it. 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.
