Description

Technical Field

[0001] This utility model relates to the field of shield tunnels, specifically a shield tunnel support that allows railcars to pass through. Background Technology

[0002] Shield tunneling is a tunnel construction method used for underground engineering projects. It is mainly used to build underground infrastructure such as subways, railways, highways, and sewers. It usually requires the use of shield tunneling machines, which are large tunnel boring machines that can excavate tunnels underground. However, while excavating the tunnel, it is necessary to support and protect the tunnel structure.

[0003] Chinese Patent CN114263485B discloses a prestressed support for shield tunnel support and its usage method, including a central support and four main legs. The central support is a cross-shaped steel frame structure, and the four main legs are respectively set at the ends of the central support. One end of each main leg is connected to the central support, and the other end is in close contact with the inner wall of the shield tunnel segment. A support pier is set between two adjacent main legs and the shield tunnel segment. However, the existing device still has some shortcomings. After the tunnel is excavated, workers still need to carry out decoration work, so a railcar is needed to move various materials. However, the existing support structure cannot allow the railcar to pass during use. Therefore, we propose a shield tunnel support that allows the railcar to pass to solve the above problems.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution for a shield tunnel support that allows railcars to pass through.

[0021] A shield tunnel support system for a passable railcar includes a tunnel body 1. Multiple support ring beams 2 are placed inside the tunnel body 1. Each support ring beam 2 has a support cross beam 3 installed on its inner ring. A connecting component 6 is installed below each support cross beam 3. A transport component 5 is installed above each connecting component 6. Reinforcing components 16 are installed on the inner wall of each support cross beam 3. A support component 14 is installed below each connecting component 6. Through the cooperation of the support ring beams 2 and support cross beams 3, the tunnel can be supported and protected. Simultaneously, the transport component 5 can be installed via the connecting components 6 installed below the support cross beams 3, allowing a small railcar 9 to move within the tunnel body 1 without affecting the tunnel support system. Therefore, this device effectively solves the problem that existing devices cannot allow railcars to pass during use. Before installing the tunnel support, thorough preparation is essential. First, the tunnel interior must be cleaned to ensure there are no debris or obstacles. Second, the position and dimensions of the steel arch frame are determined according to the design drawings, and the necessary support components, connectors, and fasteners are prepared. After preparation, the support is assembled. The assembled support needs to be correctly installed into the tunnel and securely fixed. First, professional hoisting equipment is used to lift the support to the designated position. Then, fasteners are used to tightly connect the support to the tunnel wall to ensure its stability and load-bearing capacity. During installation, special attention must be paid to safety to ensure the personal safety of construction personnel is not threatened.

[0022] Each connecting component 6 includes a supporting steel beam 13, and a reinforcing beam 18 is installed on the bottom surface of each supporting steel beam 13. By installing multiple reinforcing beams 18 on the bottom surface of the supporting steel beam 13, the stress strength of the supporting steel beam 13 can be increased. A supporting plate 12 is installed on the upper surface of each supporting steel beam 13, and a connecting plate 7 is installed on the upper surface of each set of supporting plates 12. A supporting component 14 is installed on the bottom surface of each connecting plate 7, and each supporting component 14 includes a supporting block 15. The bottom surface of each supporting block 15 is connected to the tunnel body 1. The supporting component 14 can support the connecting plate 7, increasing the stability of the device.

[0023] The transport component 5 includes a transport track 8 and a small railcar 9. The bottom surface of the small railcar 9 is equipped with multiple rail transport wheels 19, each of which is in contact with the transport track 8. The small railcar 9 plays a crucial role in the construction and operation of the tunnel, especially in scenarios where materials, equipment and personnel need to be transported frequently. Through the cooperation between the rail transport wheels 19 and the transport track 8, and with its high efficiency, safety and convenience, it greatly improves the efficiency of construction and transportation.

[0024] Each reinforcing component 16 includes a reinforcing plate 17. The bottom end of each reinforcing plate 17 is in contact with the upper surfaces of two connecting plates 7. The two reinforcing plates 17 can fix the connection between the two connecting plates 7 to prevent misalignment between the two connecting plates 7, which would cause the transport track 8 laid on the connecting plate 7 to bend and cause the small railcar 9 to shake.

[0025] Each supporting cross beam 3 has an internal top wall equipped with a lighting lamp 10. The lighting lamp 10 plays a crucial role in the tunnel construction process, mainly to provide necessary illumination to ensure the safety and efficiency of construction. Since the tunnel construction environment is usually quite complex, insufficient light will increase the construction risk. The construction lighting lamp 10 can provide sufficient brightness so that construction personnel can clearly see the work area, equipment and materials, thereby reducing accidents caused by poor visibility. Each supporting cross beam 3 has an internal wall equipped with a warning loudspeaker 11. The warning loudspeaker 11 is connected to the tunnel construction safety system and can sound an alarm when a problem occurs to remind construction personnel and passing vehicles of the existence of the construction area, thereby reducing the risk of accidents. In some complex construction environments, the warning loudspeaker 11 can be used in conjunction with other warning devices to provide multi-level early warning, ensuring the clarity and effectiveness of information transmission. The models of various electrical components in the device should be based on the actual use.

[0026] Multiple auxiliary support beams 4 are installed on the outer surface of each supporting cross beam 3. Each auxiliary support beam 4 is connected to the inner wall of the supporting ring beam 2. By installing multiple auxiliary support beams 4 between the supporting cross beam 3 and the supporting ring beam 2, the support can be subjected to uniform force, thereby ensuring the safety of the tunnel.

[0027] The working principle of this utility model is as follows: When using this shield tunnel support with a passable railcar, workers first use a shield machine to drill holes in the tunnel body 1. Then, workers install the support ring beam 2 on the inner wall of the tunnel, and at the same time, install the support cross beam 3 to support the support ring beam 2. Next, a connecting component 6 is installed below the support cross beam 3, and a transport component 5 is installed on the upper surface of the connecting component 6. Then, the small railcar 9 installed in the transport component 5 can transport materials, thereby transporting the materials into the tunnel to ensure the normal operation of construction.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
