Description

Technical Field

[0001] This invention relates to the field of tunnel spraying technology, and in particular to a tunnel vibration damping material construction spraying equipment and spraying method. Background Technology

[0002] With the continuous development of mountain highway tunnel construction, numerous vibration problems such as earthquakes and vehicle vibrations are encountered during tunnel operation. To improve the seismic resistance and vibration reduction performance of tunnel structures, polymer damping materials are often sprayed onto the tunnel walls and other parts. However, there are currently many shortcomings in the application of polymer damping materials to mountain highway tunnels.

[0003] During the spraying process, the direction of the nozzle needs to be manually controlled. Manually controlling the direction and position of the spraying will cause uneven spraying, which requires re-spraying and ultimately introduces instability into the construction. At the same time, the construction efficiency is low and cannot meet the needs of large-scale construction of mountain highway tunnels.

[0004] Chinese utility model patent CN220346283U discloses a fire-retardant coating spraying device for highway tunnels. Its working principle is as follows: First, the device is propelled to the application location using wheels, and electrical components are connected to a battery. Then, raw materials are poured into a mixing tank and sealed with a cap. Next, the control display screen is activated to start a rotating motor that drives a stirring rod for mixing. The motor's speed is adjusted and started using the control display screen. The rotation of the motor causes a second gear to drive a first gear, a rotating rod, a swing tube, and a spray head to swing back and forth. Simultaneously, a material pump is activated. Finally, the material pump sprays the fire-retardant coating from the spray head, applying it to the tunnel walls and ceiling. Simultaneously, supplementary lighting and infrared indicator lights are activated as needed, and the device is moved while spraying. This method solves the problems mentioned earlier, where workers manually mix the fire-retardant coating and then manually spray it onto the tunnel walls and ceiling, resulting in high physical exertion and slow construction speed.

[0005] In the above operation, the spraying and oscillation are controlled by power equipment, which requires a lot of power equipment, resulting in high cost. In addition, different power equipment needs to be started and stopped separately, which makes the control difficult and makes it difficult to ensure synchronization of the control process, which is not conducive to the spraying operation. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies in tunnel material spraying, where spraying and oscillation are controlled by separate power equipment, requiring a large number of power devices, resulting in high costs. Furthermore, different power devices need to be started and stopped separately, leading to high control difficulty and difficulty in ensuring synchronization during the control process, which is not conducive to the spraying operation.

[0022] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0023] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer," etc., used in the description of specific embodiments of the present invention to indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0024] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2mm-1mm, preferably within 0.2mm-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the solution of the present invention.

[0025] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0026] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0027] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to connection methods commonly used in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0028] Example 1 Please see Figures 1 to 12A tunnel vibration damping material spraying equipment includes a construction vehicle 1, a power unit 2, a swinging construction unit 4, a dust collection unit 5, a power transmission unit 6, and a material supply unit 7. The power unit 2, swinging construction unit 4, dust collection unit 5, power transmission unit 6, and material supply unit 7 are all mounted on the construction vehicle 1 and moved together by the construction vehicle 1. The dust collection unit 5 is optional; however, it is included to improve the spraying effect. Figure 1 A dust collection component 5 is installed in the middle.

[0029] The power unit 2 can drive the swinging construction unit 4 to swing back and forth in the left and right directions of the construction vehicle 1, so as to... Figure 1 For example, the left front of the vehicle represents the front side of the construction vehicle 1, and the right rear of the vehicle represents the rear side of the construction vehicle 1. The top of the swing construction component 4 is equipped with a material spray nozzle 42, that is, the power component 2 can provide power to the swing construction component 4, and can drive the material spray nozzle 42 to swing back and forth in the left and right directions of the construction vehicle 1. There is no need to manually control the spraying direction and position, so that the material will be sprayed more evenly, the construction stability will be higher, and the construction efficiency will be effectively improved. If the front and rear directions of the construction vehicle 1 are aligned with the axis of the tunnel, the material spray nozzle 42 can automatically swing back and forth in the left and right directions of the construction vehicle 1 when spraying the material, so that one cross section of the tunnel can be sprayed repeatedly, resulting in a better spraying effect. After the construction vehicle 1 moves forward, it can be sprayed repeatedly on the next cross section. The power transmission component 6 is connected to the power component 2, and the material supply component 7 is installed on the construction vehicle 1. The power transmission component 6 can drive the material supply component 7 to supply and spray the material to the material spray nozzle 42, that is, the power component 2 can provide power to the material supply component 7, so that the material supply component 7 can work without an additional power source.

[0030] That is, the swinging construction component 4 is driven by the power component 2 to drive the material spray nozzle 42 to swing back and forth in the left and right directions of the construction vehicle 1, and the material supply component 7 is driven by the power transmission component 6 to supply material spray nozzle 42 for spraying. Since everything is controlled by the same power component 2, less power equipment is required, the cost is lower, and energy can be saved. Moreover, the swinging and spraying of the material spray nozzle 42 can be realized simultaneously by only starting the power equipment, which makes the control easier and the synchronization control better.

[0031] In this embodiment, the power component 2 can simultaneously drive the swing construction component 4 and the power transmission component 6 in the following manner: For reference Figure 1The power component 2 includes a drive motor 24, the power shaft of which is horizontally arranged along the front-rear direction of the construction vehicle 1. The drive motor 24 can drive the swinging construction component 4 to swing back and forth in the left-right direction of the construction vehicle 1. like Figure 1 and Figure 10 As shown, the power transmission component 6 includes a support plate 61, a third pulley 62, a second transmission belt 63, a fourth pulley 64, a third rotating shaft 65, a first bevel gear 66, and a fourth rotating shaft 67. The axial directions of the third pulley 62, the fourth pulley 64, the third rotating shaft 65, and the fourth rotating shaft 67 are all horizontally arranged along the front-rear direction of the construction vehicle 1. The support plate 61 is fixedly mounted on the construction vehicle 1. The third rotating shaft 65 is rotatably mounted on the upper end of the support plate 61. The fourth pulley 64 is fixedly mounted on one end of the third rotating shaft 65, and the first bevel gear 66 is fixedly mounted on the other end. The fourth rotating shaft 67 is rotatably mounted on the lower end of the support plate 61. The third pulley 62 is fixedly mounted on the fourth rotating shaft 67. The second transmission belt 63 is installed between the fourth pulley 64 and the third pulley 62. The drive motor 24 can drive the fourth rotating shaft 67 to rotate. like Figures 11-12 As shown, the feeding component 7 includes a material box 71, a discharge pipe 72, a moving screw 74, a discharge drive component 75, and a discharge pressure plate 76. The material box 71 is fixedly installed on the construction vehicle 1. The discharge pressure plate 76 is vertically movably arranged inside the material box 71. The discharge pressure plate 76 is horizontally arranged and adapted to the horizontal cross-section of the material box 71. The vertically arranged moving screw 74 is fixedly connected to the upper side of the discharge pressure plate 76, and the upper end of the moving screw 74 penetrates through the top of the material box 71. The discharge drive component 75 includes a rotating base 751 and an internal threaded sleeve. The rotating base 751 is fixedly installed on the top outer side of the material box 71. The internal threaded sleeve 752 is rotatably installed on the rotating base 751. The internal threaded sleeve 752 is threadedly connected to the moving screw 74. The second bevel gear 753 is fixedly installed on the outer side of the internal threaded sleeve 752. The second bevel gear 753 meshes with the first bevel gear 66. The bottom of the material box 71 is connected to the discharge pipe 72. The end of the discharge pipe 72 is connected to the material spray nozzle 42 of the swing construction component 4.

[0032] The principle of the above structure is as follows: the drive motor 24 drives the fourth rotating shaft 67 to rotate, which in turn drives the third pulley 62 to rotate. The third pulley 62 drives the fourth pulley 64 through the second transmission belt 63. The fourth pulley 64 drives the first bevel gear 66 to rotate through the third rotating shaft 65. The first bevel gear 66 drives the second bevel gear 753 to rotate. The second bevel gear 753 drives the internal threaded sleeve 752 to rotate. Since the internal threaded sleeve 752 is rotatably mounted on the rotating base 751, it cannot move vertically. Consequently, the moving screw 74 rotates relative to the internal threaded sleeve 752 and moves vertically downward, causing the discharge plate 76 to squeeze the material in the material box 71 downward. The material is squeezed from the discharge pipe 72 to the material spray nozzle 42 for spraying. That is, it can simultaneously drive the swing of the swing construction component 4 and the material spray nozzle 42 for feeding and spraying through the same drive motor 24. It can be used for the spraying construction of polymer damping materials in mountain highway tunnels.

[0033] To improve the stability of the downward movement of the discharge platen 76, such as Figure 11 As shown, the material box 71 is equipped with a discharge guide 73, which includes a guide frame 731, a sliding block 732, and a vertically arranged guide rail 733. The guide rail 733 is fixedly installed on opposite sides of the material box 71, and the sliding block 732 is slidably installed in the guide rail 733 on each side. The guide frame 731 includes a horizontal beam located above the internal threaded sleeve 752 and vertical beams connected to both ends of the horizontal beam. The vertical beams at both ends correspond to the sliding blocks 732 on both sides, and the lower ends of the vertical beams at both ends are fixedly connected to the corresponding sliding blocks 732. The upper end of the moving screw 74 is fixedly connected to the horizontal beam, so that the guide frame 731 and the sliding block 732 can move down along the guide rail 733 as a whole, thereby achieving radial limiting of the moving screw 74, improving the stability of the discharge pressure plate 76 moving downward, and making the spraying of the coating material more uniform and stable. Furthermore, the discharge guide 73 can limit the moving screw 74, so that the moving screw 74 can only move up and down and cannot rotate, so that the moving screw 74 can move up and down normally under the drive of the discharge drive 75, and prevent the moving screw 74 from rotating with the discharge drive 75.

[0034] In an optional embodiment, the tunnel vibration damping material construction spraying equipment also includes a dust collection structure, which includes a dust collection hood 43, capable of performing dust collection operations on the tunnel wall, thereby improving the spraying quality of subsequent material spraying.

[0035] Furthermore, such as Figure 1As shown, the dust suction hood 43 is located on the top of the swing construction component 4. The dust suction hood 43 is closer to the front of the construction vehicle 1 than the material spray nozzle 42, which means that the next tunnel cross section to be sprayed can be cleaned in advance, which facilitates the continuity of subsequent spraying.

[0036] In optional implementations, such as Figures 1-12 As shown, there are two dust collection components 5. The two dust collection components 5 are symmetrically installed on the power component 2 in the left and right directions of the construction vehicle 1. The power component 2 can drive the dust collection components 5 to work, and can automatically absorb and remove dust from the tunnel surface before spraying the tunnel, making the tunnel surface cleaner and facilitating the adhesion of polymer materials to the tunnel surface.

[0037] In this embodiment, the swing construction component 4, the dust collection component 5, and the material supply component 7 can all work simultaneously through a single power component 2, achieving the effect of one machine serving three purposes. This makes full use of power, helps save energy, is easy to control, and improves efficiency.

[0038] like Figures 2-4 As shown, the power unit 2 includes a vertical plate 21, a dual-power drive component 22, a swing drive component 23, and a drive motor 24. The vertical plate 21 is arranged along the left-right direction of the construction vehicle 1 and is vertically fixed on the construction vehicle 1. The dual-power drive component 22 is installed on the right side of the vertical plate 21, that is, on the side of the vertical plate 21 away from the front side of the construction vehicle 1. The swing drive component 23 is installed on the left side of the vertical plate 21, that is, on the side of the vertical plate 21 close to the front side of the construction vehicle 1. The upper drive end of the dual-power drive component 22 can drive the swing drive component 23 to rotate. The drive motor 24 is installed on the construction vehicle 1, and the rotating end of the drive motor 24 is connected to the lower drive end of the dual-power drive component 22.

[0039] like Figure 4As shown, the dual-power drive unit 22 includes a first rotating shaft 221, a first pulley 222, a first transmission belt 223, a second rotating shaft 224, and a second pulley 225. The first rotating shaft 221, the first pulley 222, the second rotating shaft 224, and the second pulley 225 are all horizontally arranged along the front-rear direction of the construction vehicle 1. The first rotating shaft 221 and the second rotating shaft 224 are both rotatably mounted on the vertical plate 21. The first rotating shaft 221 is located above the second rotating shaft 224. The first pulley 222 is mounted on the right end of the first rotating shaft 221 located on the vertical plate 21, and the second pulley 225 is mounted on the right end of the second rotating shaft 224 located on the vertical plate 21. A first transmission belt 223 is installed between the first pulley 222 and the second pulley 225. The left end of the first rotating shaft 221 is connected to the swing drive unit 23, and the right end of the second rotating shaft 224 is connected to the drive motor 24.

[0040] The swing drive component 23 includes a rotating disk 231, an adjusting component 232, and a convex frame 233. The convex frame 233 is fixedly connected to the outer side of the rotating disk 231. The convex frame 233 has an arc-shaped structure and has a long end and a short end that are arranged opposite to each other, similar to the outer edge structure of a cam. The rotating disk 231 is fixedly installed on the upper end of the dual-power drive component 22, that is, the rotating disk 231 is fixedly installed on the left end of the first rotating shaft 221. A rectangular groove is opened on the left side of the rotating disk 231. The adjusting component 232 is installed on the rotating disk 231 at the rectangular groove. The position of the driving end of the swing drive component 23 can be adjusted by adjusting the adjusting component 232, so as to adjust the swing angle of the swing construction component 4 according to the construction requirements during the construction process.

[0041] like Figure 5 As shown, the adjusting component 232 includes a movable block 2321, an adjusting screw 2322, and an adjusting knob 2323. The movable block 2321 is movably installed in a rectangular groove on the rotating disk 231. The movable block 2321 is L-shaped, with one end inserted into the rectangular groove and the other end located outside the groove. The upper end of the movable block 2321 is rotatably connected to the adjusting screw 2322. The upper end of the adjusting screw 2322 passes through the rotating disk 231 and is threadedly connected to it. An adjustment knob 2323 is connected to the upper end of the adjusting screw 2322, and a swing drive block 2324 is fixedly connected to the end of the moving block 2321. The swing drive block 2324 is inserted into the swing slot 412. When the adjustment knob 2323 is rotated, the adjusting screw 2322 can be rotated. Since the adjusting screw 2322 is threadedly connected to the side wall of the rotating disk 231, the rotation of the adjusting screw 2322 can drive the moving block 2321 to move along the rectangular groove, thereby adjusting the position of the swing drive block 2324.

[0042] like Figure 6As shown, the swing construction component 4 includes a swing rod 41, a material spray nozzle 42, and a dust suction hood 43. The lower end of the swing rod 41 is rotatably mounted on the power component 2, so that the swing rod 41 can swing cyclically under the action of the power component 2. The material spray nozzle 42 is fixedly mounted on the upper right side of the swing rod 41. The inlet of the material spray nozzle 42 is connected to the feeding component 7. The dust suction hood 43 is mounted on the upper left side of the swing rod 41. The air intake of the dust suction hood 43 is connected to the dust suction component 5. By driving the swing construction component 4 through the power component 2, it can continuously swing back and forth, simulating the swinging motion of a worker during the spraying process.

[0043] Specifically, such as Figure 6 As shown, the swing arm 41 includes a T-shaped rod 411, a swing groove 412, and a rotating bearing 413. The T-shaped rod 411 has a horizontal rod at the top and a vertical rod at the bottom. The horizontal rod is arranged along the front-rear direction of the construction vehicle 1. The dust suction hood 43 and the material spray nozzle 42 are arranged at the top of the horizontal rod and face upwards. A vertical swing groove 412 is opened in the middle of the vertical rod. The swing groove 412 can be a blind hole or a through hole. When the swing groove 412 is a through hole, The penetrating direction of the swing groove 412 is the front-to-back direction of the construction vehicle 1. A rotating bearing 413 is installed at the lower end of the vertical rod, and the axial direction of the rotating bearing 413 is the front-to-back direction of the construction vehicle 1. The rotating bearing 413 is sleeved on the second rotating shaft 224. This design ensures that the rotation of the T-shaped rod 411 and the second rotating shaft 224 do not affect each other, so that the rotation of the T-shaped rod 411 is driven only by the swing drive component 23, and the second rotating shaft 224 does not affect the T-shaped rod 411 during rotation. Figure 1 and Figure 4 As shown, three material spray nozzles 42 are set on the horizontal bar along the left and right directions of the construction vehicle 1. The middle material spray nozzle 42 is set along the length of the vertical bar, and the material spray nozzles 42 on both sides are set at an angle to the middle material spray nozzle 42 and diverge in the left and right directions of the construction vehicle 1, which can improve the spraying quality and spraying efficiency.

[0044] like Figures 7-8 As shown, the dust collection component 5 includes a suction cylinder 51, a suction piston 52, a suction assembly 53, a suction pipe 54, and an exhaust pipe 55. The suction cylinder 51 is installed on the front side of the vertical plate 21 near the construction vehicle 1. The length direction of the suction cylinder 51 is along the left and right direction of the construction vehicle 1. The suction piston 52 is movably installed inside the suction cylinder 51. The suction piston 52 can move along the length direction of the suction cylinder 51. The suction assembly 53 includes a pull rod 531, a push plate 532, a telescopic rod 533, and a spring 534. One end of the pull rod 531 is fixedly connected to the suction piston 52, and the other end of the pull rod 531 extends out of the suction cylinder 51 and is fixedly connected to the push plate 532. The push plate 532 is located close to the convex frame 233 and can contact the short end of the convex frame 233. A telescopic rod 533 is installed between the push plate 532 and the side wall of the suction cylinder 51, and a spring 534 is sleeved on the telescopic rod 533. An air suction pipe 54 is installed at the end of the air suction cylinder 51 away from the air suction assembly 53, and the air suction pipe 54 is connected to the dust suction hood 43; an exhaust pipe 55 is installed at the bottom of the air suction cylinder 51 near the air suction pipe 54; a one-way valve is installed on both the air suction pipe 54 and the exhaust pipe 55.

[0045] When the convex frame 233 rotates with the power component 2, it can alternately squeeze the two push plates 532 on the left and right. When the long end of the convex frame 233 contacts the push plate 532, the push plate 532 is squeezed towards the suction cylinder 51. When the gas in the suction cylinder 51 is discharged through the exhaust pipe 55, when the short end of the convex frame 233 contacts the push plate 532, under the action of the rebound force of the spring 534, the suction component 53 moves away from the suction cylinder 51 by its own rebound force. At this time, the air pressure inside the suction cylinder 51 becomes lower, and the outside gas can enter the suction cylinder 51 along the suction pipe 54. At this time, the dust suction hood 43 on the swing construction component 4 can adsorb the dust on the inner wall of the tunnel.

[0046] Furthermore, there are two dust-collecting components 5, which are respectively placed on both sides of the convex frame 233 in the left and right directions of the construction vehicle 1. Therefore, when the power component 2 is working, the rotation of the convex frame 233 causes its long end and short end to repeatedly contact the push plate 532 of the two dust-collecting components 5, so that the two dust-collecting components 5 can work alternately. The two dust-collecting components 5 work together to enable the dust-collecting hood 43 to work continuously and avoid leakage during dust collection.

[0047] Furthermore, the construction vehicle 1 is also equipped with a filter box 8. The ends of the two exhaust pipes 55 of the two dust collection components 5 are connected to the filter box 8. The gas discharged from the exhaust pipes 55 is filtered by the filter box 8, which can prevent the gas from polluting the environment inside the tunnel.

[0048] The working principle of the tunnel vibration damping material spraying equipment is as follows: When in use, the construction vehicle 1 is moved into the tunnel, and the drive motor 24 is powered on. After the drive motor 24 is powered on, it can drive the second rotating shaft 224 to rotate. Under the transmission action of the first transmission belt 223, the first rotating shaft 221 also rotates at the same time. The first rotating shaft 221 can drive the swing drive component 23 to rotate. During the rotation of the swing drive component 23, it can drive the swing construction component 4 to swing in a cycle. The material spray nozzle 42 and the dust suction hood 43 on the swing construction component 4 can then work to suction the dust on the inner wall of the tunnel and spray polymer material on the inner wall of the tunnel at the same time.

[0049] While the power unit 2 is working, the convex frame 233 on the power unit 2 can drive the suction component 53 to move. When the long end of the convex frame 233 contacts the suction component 53, the suction component 53 moves towards the suction cylinder 51 under the action of the convex frame 233. The gas in the suction cylinder 51 is discharged through the exhaust pipe 55. When the short end of the convex frame 233 contacts the suction component 53, the suction component 53 moves away from the suction cylinder 51 by the rebound force of the spring. At this time, the air pressure inside the suction cylinder 51 becomes lower, and the outside gas can enter the suction cylinder 51 along the suction pipe 54. At this time, the dust suction hood 43 on the swing construction component 4 can adsorb the dust on the inner wall of the tunnel.

[0050] Since the right end of the fourth rotating shaft 67 is connected to the second rotating shaft 224, the power unit 2 can drive the power transmission unit 6 to work. The power transmission unit 6 can drive the discharge drive 75 to rotate. When the discharge drive 75 rotates, the moving screw 74 can move up and down. When the moving screw 74 moves, it can drive the discharge pressure plate 76 to move. When the discharge pressure plate 76 moves downward, it can squeeze the material inside the material box 71. The squeezed material is discharged through the discharge pipe 72. The end of the discharge pipe 72 is connected to the material spray nozzle 42, so that the material spray nozzle 42 can be fed. The material box 71 can be selected with a large volume. After use, the material box 71 can be refilled and the moving screw 74 can be moved upward.

[0051] It should be noted that the specific model and specifications of the drive motor 24 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, and therefore will not be described in detail. The power supply and principle of the drive motor 24 are clear to those skilled in the art, and will not be described in detail here.

[0052] Example 2 This invention provides a method for spraying tunnel vibration damping materials, which uses the tunnel vibration damping material spraying equipment described in Example 1 to spray the material onto the tunnel cross section, and includes the following steps: S1: Move the tunnel vibration damping material construction and spraying equipment into the tunnel and make the front and rear direction of the construction vehicle 1 of the tunnel vibration damping material construction and spraying equipment the axis of the tunnel, and make the tunnel vibration damping material construction and spraying equipment located on the cross section of the tunnel to be sprayed. S2: The power component 2 of the tunnel vibration damping material construction spraying equipment drives the swing construction component 4 to swing and synchronously drives the feeding component 7 to feed and spray the material to the spray nozzle 42; after the current tunnel cross section to be sprayed is completed, the power component 2 stops driving. S3: Move the tunnel vibration damping material spraying equipment forward one spraying station along the tunnel axis, and then drive the swinging construction component 4 to swing through the power component 2 and simultaneously drive the material supply component 7 to supply material to the spray nozzle 42 for spraying; after the current tunnel cross section to be sprayed is completed, stop driving the power component 2; and when a dust collection structure is provided, the dust collection hood 43 can be driven synchronously through the power component 2 to collect dust from the next working station, ensuring the continuity of spraying and improving construction efficiency.

[0053] S4: Repeat S3 until the tunnel damping material spraying is completed.

[0054] The described tunnel vibration damping material spraying method, using the described tunnel vibration damping material spraying equipment, sprays from front to back, starting from the initial cross-section of the tunnel to be sprayed, resulting in higher spraying efficiency. It can be used for spraying construction in mountain tunnels.
