Description

Technical Field

[0001] This utility model relates to the field of rail transit construction technology, specifically to a segment pre-reserved channel support tool rail with vibration reduction and noise reduction functions. Background Technology

[0002] Currently, underground construction of rail transit often requires the use of construction equipment for material transportation and construction. Therefore, this equipment needs to move within the tunnel for operator access. In this case, the equipment typically requires tool rails for movement. Currently, these tool rails are usually laid directly on the tunnel lining segments, and then temporarily secured by drilling holes in the segments to install fasteners. This ensures the stability of the tool rail structure and further guarantees the stability and safety of the moving equipment. However, this drilling process can damage the tunnel lining segments, and restoration is required after construction is completed. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a segment pre-reserved channel support tool rail with vibration reduction and noise reduction functions. The tool rail is quickly installed by utilizing the segment pre-reserved channel in conjunction with prefabricated components, while simultaneously enabling the tool rail to have vibration reduction and noise reduction functions, thereby improving construction quality.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A support rail for a pre-reserved channel in a tunnel segment with vibration reduction and noise reduction functions includes a steel rail. The rail is characterized by comprising a bracket fixed at the pre-reserved channel position in the tunnel segment. The bracket includes a high-strength steel plate, a first high-strength steel component, and a second high-strength steel component. Bolt holes are provided on the high-strength steel plate. The first high-strength steel component is welded to the high-strength steel plate, and the second high-strength steel component is mounted on the first high-strength steel component. The position between the two components is rotatably adjustable and can be locked by bolts. The second high-strength steel component is fixed to the steel rail by mounting fasteners.

[0006] A rotation point hole and an angle fixing hole are provided between the first high-strength steel component and the second high-strength steel component. The rotation point hole is used for the position rotation between the first high-strength steel component and the second high-strength steel component, and the angle fixing hole is used for fixing the position of the first high-strength steel component and the second high-strength steel component after rotation adjustment.

[0007] The second high-strength steel component is fitted with a vibration damping pad at the position corresponding to the tool rail.

[0008] The first high-strength steel component and the second high-strength steel component are respectively provided with positioning holes. When the position between the two is adjusted by rotation, they are locked by bolts inserted into the positioning holes.

[0009] The structure of the high-strength steel plate is compatible with the structure of the tunnel lining segments.

[0010] Both the first high-strength steel component and the second high-strength steel component are prefabricated.

[0011] A buffer pad is installed underneath the high-strength steel plate.

[0012] The advantages of this utility model are: it enables non-destructive installation of the tool rail, ensuring the integrity of the tunnel segments and avoiding damage; it reduces vibration and noise during use, significantly improving project quality; it has a high degree of prefabrication, is easy to install and dismantle, ensures construction efficiency, and is suitable for widespread application.

[0016] The features of this utility model and other related features will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0017] like Figure 1-3 As shown in the figure, numbers 1-10 represent: 1. High-strength steel plate, 2. Mounting hole, 3. First high-strength steel component, 4. Second high-strength steel component, 5. Rail, 6. Fastener device, 7. Rotation point hole, 8. Buffer pad, 9. Angle fixing hole, and 10. Buffer pad.

[0018] Example: Figure 1 and Figure 2 As shown, in this embodiment, the pre-reserved groove support tool rail with vibration reduction and noise reduction function is used to fix the rail 5 and install it on the tunnel segment. The tunnel segment has a pre-reserved groove.

[0019] Specifically, this embodiment includes a prefabricated component consisting of a high-strength steel plate 1, a first high-strength steel component 3, and a second high-strength steel component 4. The high-strength steel plate 1 serves as a connector between the prefabricated component and the tunnel segment. It has several mounting holes 2. By screwing the connectors into the mounting holes 2, the high-strength steel plate 1 can be fixed to the pre-reserved grooves on the tunnel segment. This facilitates installation and removal, and utilizes the pre-reserved grooves on the tunnel segment for fixation, avoiding additional drilling damage to the tunnel segment.

[0020] The first high-strength steel component 3 is welded onto the high-strength steel plate 1. A rotation point hole 7 and three angle fixing holes 9 are formed on the first high-strength steel component 3. The second high-strength steel component 4 is assembled onto the first high-strength steel component 3. The second high-strength steel component 4 also has corresponding rotation point holes and angle fixing holes. Before assembly and fixing, the relative angle between the second high-strength steel component 4 and the first high-strength steel component 3 can be adjusted through the rotation point holes to adapt to different tool rail installation requirements; that is, the first high-strength steel component 3 and the second high-strength steel component 4 form a hinge at the position of the rotation point hole 7, making the position of the second high-strength steel component 4 relative to the first high-strength steel component 3 adjustable. Once the relative position between the second high-strength steel component 4 and the first high-strength steel component 3 is determined, bolts are screwed into the corresponding angle fixing holes 9 to lock the first high-strength steel component 3 and the second high-strength steel component 4, ensuring accurate positioning and structural stability.

[0021] like Figure 3 The diagram shows the first high-strength steel component 3 and the second high-strength steel component 4 combined at a certain angle. During use, the high-strength steel plate 1 is fixed to the pre-reserved channel of the tunnel segment through the mounting holes 2. A fastening device 6 is installed on the second high-strength steel component 4, and the rail 5 is fastened and fixed to the second high-strength steel component 4 through the fastening device 6, thereby achieving non-destructive installation of the rail 5.

[0022] In this embodiment, a buffer pad 10 is further provided on the surface of the second high-strength steel member 4. The buffer pad 10 includes a portion disposed between the second high-strength steel member 4 and the rail 5, and a portion disposed between the rail 5 and its fastening device 6. The buffer pad 10 can avoid the adverse effects of the vibration generated by the rail 5 during use on the tunnel segments, and can also further reduce construction noise.

[0023] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
