The protective structure 100 is used to protect the ballast 200 of the ballast bed. The protective structure 100 includes a plurality of concrete sleepers 10, a protective plate 20, and a sealing layer 30. The sealing layer 30 is located between the concrete sleeper 10 and the protective plate 20.

[0036] In the second embodiment, the concrete sleeper 10 is a support member of the protective structure 100. The concrete sleeper 10 is used to support the protective plate 20 and the sealing layer 30. A plurality of concrete sleepers 10 are arranged along the horizontal direction and are relatively flat; a gap is formed between the plurality of concrete sleepers 10, and the gap accommodates the ballast 200 so that the ballast 200 can be accommodated between the plurality of concrete sleepers 10; the upper surfaces of the plurality of concrete sleepers 10 are support surfaces, and the upper surfaces of the plurality of concrete sleepers 10 are used to support the track so that the track can be fixed on the upper surfaces of the plurality of concrete sleepers 10.

[0037] In the embodiment of the present application, the protection plate 20 is located between two adjacent concrete sleepers 10; the protection plate 20 is respectively installed on two adjacent concrete sleepers 10, so as to facilitate the fixation of the protection plate 20 to two adjacent concrete sleepers 10. The protection plate 20 is positioned and connected to two adjacent concrete sleepers 10, so as to ensure the position accuracy of the protection plate 20 relative to two adjacent concrete sleepers 10; the protection plate 20 is located above the ballast 200 in the gap and covers the ballast 200 in the gap to protect the ballast 200, preventing the ballast 200 from flowing to the external environment through the protection plate 20, avoiding the protection of covering the ballast 200 with geotextile, improving the protection effect of the protection structure 100 on the ballast 200, and facilitating the prevention of dust pollution.

[0038] In the embodiment of the present application, the sealing layer 30 is located between the protection plate 20 and the concrete sleeper 10 and acts on the connection between the protection plate 20 and the concrete sleeper 10. Under the action of the sealing layer 30, the protection plate 20 is sealingly connected to the concrete sleeper 10.

[0039] At this time, based on the connection of the protection plate 20 between two adjacent concrete sleepers 10 and the sealing connection to the concrete sleeper 10 under the action of the sealing layer 30, the connection between two adjacent concrete sleepers 10 is realized. The protection plate 20 is located above the ballast 200 in the gap and covers the ballast 200 in the gap to protect the ballast 200, avoiding the protection of covering the ballast 200 with geotextile, improving the protection effect of the protection structure 100 on the ballast 200, and facilitating the prevention of dust pollution.

[0040] In the embodiment of the present application, two adjacent concrete sleepers 10 are both provided with positioning grooves 10a. The positioning grooves 10a are recessed from the top down of the concrete sleeper 10, and the two positioning grooves 10a are arranged opposite to each other along the horizontal direction; both ends of the protection plate 20 are respectively provided with positioning parts 21. The positioning parts 21 are inserted into the positioning grooves 10a and are positioned and connected to the positioning grooves 10a, so as to facilitate the positioning connection of the protection plate 20 to the concrete sleeper 10 through the positioning parts 21 and the positioning grooves 10a, so as to position both ends of the protection plate 20 on two adjacent concrete sleepers 10, thus facilitating the assurance of the position accuracy of the protection plate 20 relative to two concrete sleepers 10. Furthermore, it is convenient for the protection plate 20 to be located above the ballast 200 in the gap and cover the ballast 200 in the gap to protect the ballast 200, preventing the ballast 200 from flowing to the external environment through the protection plate 20, avoiding the protection of covering the ballast 200 with geotextile, improving the protection effect of the protection structure 100 on the ballast 200, and facilitating the prevention of dust pollution.

[0041] Optionally, the positioning groove 10a is a stepped groove or a recess; the positioning portion 21 is adapted to the positioning groove 10a. The positioning groove 10a is provided with an upper opening and a side opening, and the side opening communicates with the upper opening, so that the positioning portion 21 can enter the positioning groove 10a through the upper opening and the side opening.

[0042] At this time, the sealing layer 30 is connected to the outer wall of the positioning portion 21 and also to the inner wall of the positioning groove 10a. The outer surface of the sealing layer 30 contacts the outer surface of the positioning portion 21, and the inner surface of the sealing layer 30 contacts the inner wall of the positioning groove 10a, so that the positioning portion 21 can be hermetically connected to the positioning groove 10a through the sealing layer 30, ensuring the sealing effect between the protection plate 20 and the two adjacent concrete sleepers 10. Optionally, the sealing layer 30 is sealant.

[0043] Among them, the upper surface of the protection plate 20 is flush with the upper surface of the concrete sleeper 10, so that the upper surface of the protection plate 20 and the upper surface of the concrete sleeper 10 are on the same surface, thus facilitating the assurance of the aesthetics of the protection structure 100.

[0044] Optionally, the protection plate 20 is a concrete plate or a polymer material plate; the thickness of the protection plate 20 is 40 - 100 mm. The protection plate 20 can prevent sand and dust from polluting the ballast, extend the maintenance period, improve the economy of line operation, and ensure the safety of the moving train.

[0045] Optionally, the height of the multiple concrete sleepers 10 is 300 - 350 mm. The height of the multiple concrete sleepers 10 can be determined according to the train load and speed, and no specific limitation is made here.

[0046] In the second embodiment, the protection plate 20 is arranged horizontally and is located below the track, with a height difference from the track, avoiding interference of the protection plate 20 with the track and preventing it from affecting the movement of the moving train relative to the track.

[0047] In the second embodiment, the protection plate 20 includes a protection main body 22 and at least one protection connection portion 23. The protection connection portion 23 is integrally connected to the protection main body 22, so as to ensure the connection stability between the protection main body 22 and the at least one protection connection portion 23. The protection connection portion 23 is arranged on one side of the protection main body 22 and is connected to the corresponding concrete sleeper 10, so that the protection plate 20 can be connected to the concrete sleeper 10 through the protection connection portion 23, thereby facilitating the fixation of the protection plate 20 to the concrete sleeper 10.

[0048] At this time, each concrete sleeper 10 is provided with a clamping groove 10b. The clamping groove 10b is recessed from the outside to the inside of the concrete sleeper 10, and the notch of the clamping groove 10b faces the circumferential side. The protective connection part 23 is clamped in the clamping groove 10b, so that the protective plate 20 is connected to the concrete sleeper 10 through the protective connection part 23 and the clamping groove 10b.

[0049] Among them, the lower side wall of the protective main body 22 contacts the upper surface of the ballast 200, and the protective main body 22 covers the ballast 200 in the gap, so that the protective main body 22 presses against the ballast 200 to prevent the ballast 200 from moving.

[0050] Optionally, the protective plate 20 is a concrete plate or a polymer material plate; the thickness of the protective plate 20 is 20-80 mm. The protective plate 20 can avoid the pollution of the ballast by sand and dust, extend the maintenance cycle, improve the economy of line operation, and ensure the safety of the EMU.
