Description

Technical Field

[0001] This utility model relates to the field of tunnel lining structure support technology, specifically a deformation-resistant support device for tunnel lining structures. Background Technology

[0002] Tunnel lining structure refers to a permanent support structure constructed along the perimeter of the tunnel using reinforced concrete and other materials to prevent deformation or collapse of the surrounding rock. Its main purpose is to prevent leakage, cracking, deformation, and other problems during tunnel use, ensuring the safe operation and long-term use of the tunnel.

[0003] Generally, the tunnel lining structure bears most of the load from the upper part of the tunnel. The load-bearing capacity of the tunnel lining structure depends on the coordination and support between the internal steel arches and concrete. However, concrete cannot immediately bear loads after pouring; it requires a certain settling time. During this period, the support strength cannot be strictly guaranteed, especially in areas with complex crustal structures, which can easily lead to tunnel collapse accidents. Therefore, support devices are needed to act on the newly formed tunnel lining structure to enhance its stability.

[0004] Currently, existing support devices typically fix the structure directly to the inside of the tunnel lining structure. However, the support device is only used for a short period of time in the tunnel lining structure, and fixing the entire structure requires tedious disassembly and assembly work, which affects the efficiency of the support device and makes it impossible to efficiently complete the support work of the tunnel lining structure. Therefore, we propose a deformation-resistant support device for tunnel lining structures to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a deformation-resistant support device for tunnel lining structures, so as to solve the problem mentioned in the background art that the support devices on the market require cumbersome disassembly and assembly work during use, which affects the efficiency of the support devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant support device for a tunnel lining structure, comprising a tunnel lining structure, wherein an inverted arch casting structure is backfilled at the bottom inner side of the tunnel lining structure, a main support is provided inside the tunnel lining structure, a moving component for moving the position of the main support is provided between the main support and the inverted arch casting structure, a support component for supporting the stability of the tunnel lining structure is provided on the outer side of the main support, and a buffer component for assisting the displacement of the support component within the tunnel lining structure is provided on the support component, the buffer component being evenly distributed on the outer side of the support component.

[0007] Preferably, the movable component includes a track and track wheels. The track is fixedly installed on the invert arch casting structure, and the track wheels are installed at the lower end of the main support. The main support forms a movable structure on the track through the track wheels.

[0008] Preferably, a first hydraulic cylinder is provided at the position where the lower end of the main support contacts the track wheel, and the main support forms an up-and-down lifting structure through the first hydraulic cylinder.

[0009] Preferably, the support assembly includes a fixed support plate and a movable support plate. The fixed support plate is fixed to the upper side of the sub-support, the sub-support is installed above the main support, and the movable support plate is installed on both sides of the fixed support plate via a movable shaft.

[0010] Preferably, a second hydraulic cylinder is movably mounted on the lower side of the sub-support, and the other end of the second hydraulic cylinder is connected to the inner side of the movable support plate. The movable support plate forms an up-and-down rotating structure on both sides of the fixed support plate through the second hydraulic cylinder. A third hydraulic cylinder is movably mounted between the second hydraulic cylinder and the sub-support.

[0011] Preferably, the buffer assembly includes a contact roller, a support rod, and a spring. The support rod is connected through the fixed support plate and the movable support plate. The outer end of the support rod is equipped with a contact roller, and the outer side of the contact roller is in contact with the inner side of the tunnel lining structure. A spring is sleeved on the support rod, and the inner end of the spring is in contact with the fixed support plate and the movable support plate.

[0012] Preferably, the support rod is in the shape of a regular square prism, and the support rods are arranged at equal intervals on the fixed support plate and the movable support plate, and the support rods are movable structures on both the fixed support plate and the movable support plate.

At the same time, the main support is equipped with a fixed support plate and a movable support plate, which can comprehensively support the tunnel lining structure, effectively improve the bearing capacity of the tunnel lining structure after the initial formation, and avoid the tunnel lining structure from deforming due to low strength in the early stage.

[0015] (2) The anti-deformation support device is equipped with contact rollers, support rods and springs on the fixed support plate and the movable support plate. The contact rollers can contact the inner side of the tunnel lining structure, which facilitates the movement of the fixed support plate and the movable support plate in the support state between the tunnel lining structure and the support. At the same time, the extension and retraction of the support rod on the fixed support plate and the movable support plate provides a buffer for the support of the tunnel lining structure, which can easily adapt to the irregular surface of the inner side of the tunnel lining structure and ensure a more comprehensive support effect for the tunnel lining structure.

[0023] 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.

[0024] Please see Figure 1-6This utility model provides a technical solution: a deformation-resistant support device for a tunnel lining structure, including a tunnel lining structure 1, an inverted arch casting structure 2 backfilled at the bottom of the inner side of the tunnel lining structure 1, a main support 4 provided inside the tunnel lining structure 1, and a moving component for moving the position of the main support 4 between the main support 4 and the inverted arch casting structure 2.

[0025] Furthermore, the movable component includes a track 3 and a track wheel 10. The track 3 is fixedly installed on the invert arch casting structure 2, and the track wheel 10 is installed at the lower end of the main support 4. The main support 4 forms a movable structure on the track 3 through the track wheel 10, which facilitates the support device to change its working position in the tunnel lining structure 1 and improves the efficiency of the device.

[0026] Furthermore, a first hydraulic cylinder 9 is provided at the position where the lower end of the main support 4 contacts the track wheel 10. The main support 4 forms an up-and-down lifting structure through the first hydraulic cylinder 9, which facilitates the change of the up-and-down working position of the support device within the tunnel lining structure 1, thereby facilitating the separation of the device from the tunnel lining structure 1.

[0027] The outer side of the main support 4 is provided with a support component for supporting the tunnel lining structure 1 to maintain a stable state.

[0028] Furthermore, the support assembly includes a fixed support plate 5 and a movable support plate 6. The fixed support plate 5 is fixed on the upper side of the sub-support 8, and the sub-support 8 is installed above the main support 4, ensuring the stable working state of the fixed support plate 5. The movable support plate 6 is installed on both sides of the fixed support plate 5 through a movable shaft, which facilitates the adjustment of the working position of the movable support plate 6, thereby facilitating the support work of the movable support plate 6.

[0029] Furthermore, a second hydraulic cylinder 11 is movably installed on the lower side of the sub-support 8. The other end of the second hydraulic cylinder 11 is connected to the inner side of the movable support plate 6. The movable support plate 6 forms an up-and-down rotating structure on both sides of the fixed support plate 5 through the second hydraulic cylinder 11, which facilitates the stable up-and-down movement of the movable support plate 6. A third hydraulic cylinder 12 is movably installed between the second hydraulic cylinder 11 and the sub-support 8 to strengthen the force-bearing strength of the second hydraulic cylinder 11, thereby improving the stability of the movable support plate 6.

[0030] The support assembly is equipped with a buffer assembly that assists in the displacement of the support assembly within the tunnel lining structure 1. The buffer assemblies are evenly distributed on the outside of the support assembly.

[0031] Furthermore, the buffer assembly includes a contact roller 7, a support rod 13, and a spring 14. The support rod 13 is connected through the fixed support plate 5 and the movable support plate 6. The outer end of the support rod 13 is equipped with a contact roller 7, and the outer side of the contact roller 7 is in contact with the inner side of the tunnel lining structure 1, which facilitates the movement of the fixed support plate 5 and the movable support plate 6 with the tunnel lining structure 1 through the contact roller 7, thereby facilitating the use of the device. The support rod 13 is fitted with a spring 14, and the inner end of the spring 14 is in contact with the fixed support plate 5 and the movable support plate 6, ensuring that the support rod 13 can move freely on the fixed support plate 5 and the movable support plate 6, and also ensuring that the contact roller 7 on the support rod 13 is always in contact with the tunnel lining structure 1, thereby improving the support stability effect.

[0032] Furthermore, the support rod 13 is shaped like a regular square prism to ensure stable movement. The support rod 13 is evenly spaced on the fixed support plate 5 and the movable support plate 6. The support rod 13 is a movable structure on both the fixed support plate 5 and the movable support plate 6, ensuring that the support rod 13 provides stable and uniform support for the tunnel lining structure 1. It also easily adapts to the undulations of the inner wall of the tunnel lining structure 1, improving the overall support effect.

[0033] Working principle: When using this anti-deformation support device, firstly, a track 3 is laid on the invert arch casting structure 2 inside the tunnel lining structure 1. Then, the main support 4 can be erected on the track 3 through the track wheel 10, which facilitates the efficient movement of the main support 4 within the tunnel lining structure 1, thereby facilitating the use of the anti-deformation support device.

[0034] Then, the fixed support plate 5 is fixed above the main support 4 by the auxiliary support 8, and the movable support plate 6 is installed on both sides of the fixed support plate 5. The movable support plate 6 is supported by the second hydraulic cylinder 11 and the third hydraulic cylinder 12. The fixed support plate 5 and the movable support plate 6 can support the inner wall of the tunnel lining structure 1 to ensure the bearing capacity of the tunnel lining structure 1.

[0035] After the tunnel lining structure 1 is completed, the support strength after the concrete is poured and formed cannot be strictly guaranteed. It requires a certain period of stabilization, curing and maintenance. Therefore, this support device is used to strengthen the bearing capacity of the tunnel lining structure 1 and ensure the stable support effect of the tunnel lining structure 1 in the early period.

[0036] After the tunnel lining structure 1 is completed, the position of the main support 4 is moved so that the fixed support plate 5 and the movable support plate 6 are aligned with the part of the tunnel lining structure 1 that needs to be supported. Then, the main support 4 is raised by the first hydraulic cylinder 9, and the position of the fixed support plate 5 is moved upward. The fixed support plate 5 supports the upper part of the tunnel lining structure 1. Then, the movable support plate 6 is pressed against the two sides of the tunnel lining structure 1 by the extension and retraction of the second hydraulic cylinder 11 and the third hydraulic cylinder 12. The movable support plate 6 supports the two sides of the tunnel lining structure 1, and the support work of the tunnel lining structure 1 can be completed.

[0037] During the support of the tunnel lining structure 1, both the fixed support plate 5 and the movable support plate 6 have support rods 13 that move via springs 14, and the ends of the support rods 13 are equipped with contact rollers 7. Therefore, the fixed support plate 5 and the movable support plate 6 contact the inner wall of the tunnel lining structure 1 through the contact rollers 7. Furthermore, multiple support rods 13 are evenly arranged in an array on the fixed support plate 5 and the movable support plate 6. In this way, even if the inner wall of the tunnel lining structure 1 is not smooth, the movement of the support rods 13 can achieve full support of the tunnel lining structure 1.

[0038] During the operation of the support device, the gap between the fixed support plate 5 and the movable support plate 6 and the tunnel lining structure 1 facilitates the maintenance of the tunnel lining structure 1, thereby accelerating the formation of the tunnel lining structure 1. When it is necessary to carry out support work at the next location, the position of the main support 4 can be moved directly. The fixed support plate 5 and the movable support plate 6 move with the tunnel lining structure 1 through the contact rollers 7, which facilitates the rapid transfer of the support device and improves the efficiency of the support device.

[0039] The above describes the working process of the support device. Any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
