Description

TECHNICAL FIELD

[0001] The application relates to the field of tunnel construction supporting devices, in particular to a fastening device for tunnel engineering. BACKGROUND

[0002] In the field of tunnel engineering, with the rapid development of transportation infrastructure construction, the number and scale of tunnels are increasing, and the stratum conditions through which the tunnels pass are extremely complex, including various rocks with different hardness and loose soil bodies, etc. During the tunnel excavation process, due to the redistribution of the surrounding rock stress, the surrounding rock may deform, loosen and even collapse, which not only seriously threatens the construction safety, but also may affect the long-term stability and use performance of the tunnel.

[0003] The existing patent (announcement number: CN219452120U) discloses a fastening structure for tunnel engineering, which belongs to the field of tunnel engineering. The fastening structure for tunnel engineering comprises a support beam, a driving shaft, a support seat, an active column, a support block and a recess.

[0004] In the above-mentioned comparative document, although the position of the support block can be adjusted, it is difficult to ensure that each support block uniformly applies force to the irregular tunnel inner wall, and the support force supplemented by the air bag is limited. In the face of complex geological conditions, the air bag is difficult to provide sufficient support strength, and when the tunnel is in a humid environment, the components of the device are prone to corrosion, thereby affecting the overall performance of the fastening device. Content of the utility model

[0005] In view of the deficiencies of the prior art, the application provides a fastening device for tunnel engineering, which has the advantages of fastening and stabilizing the tunnel, supporting flexibly and stably on the gap between the fastening plates, and resisting corrosion, and solves the problems raised in the background art.

[0006] To achieve the above object, the application provides the following technical scheme: a fastening device for tunnel engineering, comprising a support beam, the bottom surface of the support beam is fixedly connected with two bases, the outer surface of the support beam is fixedly connected with two groups of hydraulic cylinders, the output end of each hydraulic cylinder is fixedly connected with a fastening plate, the upper surface of each fastening plate is fixedly connected with a corrosion-resistant plate, the outer surface of the support beam is fixedly connected with two hydraulic push rods, the telescopic end of each hydraulic push rod is fixedly connected with a reinforcing plate, the outer surface of the support beam is fixedly connected with two groups of mounting boxes, the inner bottom wall of each mounting box is fixedly connected with a damper, the upper end of each damper is fixedly connected with a connecting plate, the upper surface of each connecting plate is fixedly connected with a group of damping springs, and the upper end of each group of damping springs is fixedly connected with a compression pad.

[0007] Through the above scheme, the fastening device for tunnel engineering is formed by the cooperation of the hydraulic cylinder, the fastening plate and the corrosion-resistant plate, which constitutes the basic framework of the stable tunnel engineering structure. The hydraulic cylinder can precisely drive the fastening plate to tightly adhere to the inner wall of the tunnel by virtue of its powerful hydraulic power output. The corrosion-resistant plate can effectively resist the erosion of the fastening plate and related components in harsh environments, thereby ensuring the safety and reliability of the fastening device during long-term use. The cooperation of the damper, the damping spring and the compression pad can provide extremely stable and flexible support for the gap between the fastening plates. The damper and the damping spring can maintain stability while buffering external forces. The compression pad can flexibly respond to different height support requirements according to the actual working conditions of the fastening plate, and evenly disperse pressure, thereby enhancing the support stability and reliability. The cooperation of the hydraulic push rod and the reinforcing plate can reinforce the bottom end of the tunnel, so that it remains stable in different situations and enhances the structural strength and stability of the bottom end of the tunnel.

[0008] Further, the inner wall of the support beam is fixedly connected with a fixed plate.

[0009] Through the above scheme, the fixed plate can fix the support beam and prevent the support beam from tilting during long-term work.

[0010] Further, the inner wall of the support beam is fixedly connected with a group of supporting plates, and the bottom surface of each supporting plate is fixedly connected with the upper surface of the fixed plate.

[0011] Through the above scheme, the supporting plate can support the support beam and avoid unstable phenomena during long-term work.

[0012] Further, the upper surface of each compression pad is fixedly connected with a corrosion-resistant pad.

[0013] Through the above scheme, the corrosion prevention pad is arranged to prevent the compression pad from being corroded, effectively resist the erosion of external corrosion factors, and prolong the service life of the compression pad.

[0014] Further, the outer surface of the support beam is fixedly connected with two groups of limiting rings, and the inner walls of the two groups of limiting rings are fixedly connected with the outer surfaces of the two groups of hydraulic cylinders, respectively.

[0015] Through the above scheme, the limiting ring is arranged to limit the hydraulic cylinder, avoid the inclination and misplacement of the hydraulic cylinder during work, and ensure the safety of the hydraulic cylinder during work.

[0016] Further, the upper surface of each base is fixedly connected with a fixing frame, and the inner wall of each fixing frame is fixedly connected with the inner wall of the support beam.

[0017] Through the above scheme, the fixing frame is arranged to fix the bottom end of the support beam, and the bottom end of the support beam can be stably positioned and supported, so that the structure deformation or displacement caused by the unstable fixing of the bottom of the support beam is prevented.

[0018] Further, the inner wall of the support beam is fixedly connected with two support plates, and the bottom surfaces of the two support plates are fixedly connected with the upper surfaces of the two fixing frames, respectively.

[0019] Through the above scheme, the support plate is arranged to locally support the support beam, so that the stress is not concentrated on the local connection point, thereby reducing the risk of structural damage caused by uneven stress.

[0020] Further, the upper surface of each base is fixedly connected with a support frame, and the upper surfaces of the two support frames are fixedly connected with the outer surfaces of the two hydraulic push rods, respectively.

[0021] Through the above scheme, the support frame is arranged to support the hydraulic push rod, so that the unstable sliding phenomenon of the hydraulic push rod during work is prevented.
