Description

Technical Field

[0001] This utility model relates to the field of frame tunnel technology, specifically a prefabricated frame tunnel. Background Technology

[0002] A tunnel is an engineering structure buried in the earth's strata, representing a form of human utilization of underground space. The structure of a tunnel consists of two parts: the main building and auxiliary equipment. The main building comprises the tunnel body and portals, while the auxiliary equipment includes passing bays, fire-fighting facilities, emergency communication systems, and drainage systems. Longer tunnels also have specialized ventilation and lighting equipment. With the continuous development of society, the demand for tunnels is increasing. Traditional tunnel construction methods mostly rely on tunnel boring machines, which have high construction costs and require high continuity, placing high demands on workers. Therefore, in order to reduce costs, a prefabricated frame tunnel has been proposed.

[0003] For example, the framework structure for coal mine tunnel construction disclosed in the authorization announcement number CN217735517U includes a protective grid layer, a support structure inside the protective grid layer, a support structure including multiple baffle assemblies and support components, four reinforcing structures on the support components, multiple integrated arc-shaped guard plates, multiple insert rods fixedly connected to both sides of the integrated arc-shaped guard plates, two support components including two support assemblies, the two support components being fixedly connected by a No. 1 bolt and a No. 1 nut, two arc-shaped support plates, a fixed plate being fixedly connected to the bottom of one end of the arc-shaped support plate, and multiple sets of insert holes and two through holes on the arc-shaped support plate;

[0004] Although it achieves the goal of improving the support capacity of the support structure by sharing the pressure of the support components, and further improving the support capacity of the support structure by increasing the strength and stiffness of the support structure, thereby reducing the probability of tunnel collapse and improving the safety of the entire device.

[0005] However, this does not solve the problem that existing frame tunnels are not conducive to the convenient sliding and adaptation of culvert piers of different thicknesses for limiting support and rotation to clear accumulated debris during use, and are not conducive to the splicing and installation of culverts, thus affecting the convenience of installation and the convenience of debris removal.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figure 1-5This utility model provides an embodiment of a prefabricated frame tunnel, including culvert piers 1 and connecting culverts 12. There are two sets of culvert piers 1 and multiple sets of connecting culverts 12. Multiple sets of assembly holes 10 and assembly pins 15 are respectively installed at both ends of the connecting culverts 12, and the assembly pins 15 can be inserted into the assembly holes 10. External limiting rings 13 are installed on the outer walls of the connecting culverts 12 at both ends. The culvert piers 1 are installed on the surface of the connecting culverts 12 on one side of the external limiting rings 13. Top slide rails 8 are installed at the top of each connecting culvert 12. Side rails 6 are symmetrically installed on the side walls of pipe 12. Two sets of support columns 3 are installed at the top of culvert 1. The surface of the support column 3 is fitted with a movable sleeve 4, and the movable sleeve 4 is slidably connected to the support column 3. Locking pins 2 are installed on the outer wall of the movable sleeve 4, and the locking pins 2 penetrate the movable sleeve 4 and extend to the surface of the support column 3. A guardrail 5 is installed above the culvert 1, and the guardrail 5 is connected to the movable sleeve 4. A connecting plate 9 is installed on the side wall of a set of connecting culvert pipe 12. A culvert 11 is installed inside the connecting culvert pipe 12.

[0024] Multiple sets of connecting culverts 12 are placed sequentially in the installation position. Assembly pins 15 are inserted into the assembly holes 10, connecting the multiple sets of connecting culverts 12 via the assembly pins 15 and the assembly holes 10. Outer limiting rings 13 are installed on the surfaces of the connecting culverts 12 at both ends. The culvert pier 1 is installed on the surface of the connecting culvert 12 on one side of the outer limiting ring 13, providing limiting support for one side of the culvert pier 1. The locking bolt 16 is rotated; with the locking bolt 16 threaded into the threaded sleeve 17, the locking bolt 16 moves downwards and extends to the surface of the top slide rail 8, fixing the inner limiting ring 14 to the top slide rail 8. Thus, the inner limiting ring 14 provides limiting support for the other side of the culvert pier 1. If the thickness of the culvert pier 1 is different, the inner limiting ring 14 is slid, and the culvert pier 1 is positioned on the top slide rail 8. With the sliding engagement of the top sliding groove 18 and the sliding engagement of the side sliding groove 19 and the side sliding rail 6, the inner limiting ring 14 slides on the surface of the connecting culvert 12 to move the inner limiting ring 14 away from the outer limiting ring 13, thereby adapting to culvert piers 1 of different thicknesses. If it is necessary to protect passing vehicles and pedestrians, loosen the locking pin 2 to separate the support column 3 and the movable sleeve 4, pull the guardrail 5 upward, and the guardrail 5 will drive the movable sleeve 4 to slide on the surface of the support column 3 to adjust the height of the guardrail 5. Then, re-lock the locking pin 2 to connect the support column 3 and the movable sleeve 4 to adjust the height of passing vehicles and pedestrians for protection. This realizes convenient sliding adaptation to limit and support culvert piers of different thicknesses, facilitates the splicing and installation of culverts, and improves the convenience of installation.

[0025] An inner limiting ring 14 is provided on the surface of the connecting culvert 12 on one side of the culvert pier 1, and the inner limiting ring 14 is slidably connected to the connecting culvert 12.

[0026] Top slide grooves 18 are installed on the inner wall of the inner limiting ring 14 above the top slide rail 8, and the top slide rail 8 is slidably connected to the top slide grooves 18.

[0027] Side slide grooves 19 are installed on the inner wall of the inner limiting ring 14 on one side of the side slide rail 6, and the side slide rail 6 is slidably connected to the side slide grooves 19.

[0028] A threaded sleeve 17 is installed at the top of the inner limit ring 14. Locking bolts 16 are installed inside the threaded sleeve 17. The locking bolts 16 are threadedly connected to the threaded sleeve 17 and extend through the inner limit ring 14 to the surface of the top slide rail 8. An integrated box 7 is installed on one side of the connecting plate 9. A worm gear 22 is movably installed inside the integrated box 7. A rotating rod 21 is installed at the top of the worm gear 22. A handle 20 is installed at the top of the rotating rod 21.

[0029] A movable shaft 24 is movably installed on the other side of the connecting plate 9. A worm gear 23 is fitted on the surface of the movable shaft 24, and the worm gear 23 meshes with the worm 22. A retrieval frame 25 is provided on the outside of the connecting plate 9, and the retrieval frame 25 is connected to the movable shaft 24. A filter screen 26 is installed inside the retrieval frame 25.

[0030] Water flows through the salvage frame 25 into the culvert 11, where it is filtered and collected by the filter screen 26. If a large amount of debris accumulates on the surface of the filter screen 26, the handle 20 is turned, which drives the rotating rod 21 to rotate. The rotating rod 21 then drives the worm gear 22 to rotate. Under the meshing of the worm gear 22 and the worm wheel 23, the worm gear 22 drives the worm wheel 23 to rotate. The worm wheel 23, through the movable shaft 24, drives the salvage frame 25 and the filter screen 26 to rotate, thus rotating the salvage frame 25 and the filter screen 26 from a vertical position to a horizontal position. This facilitates the removal of debris from inside the salvage frame 25, enabling convenient rotation and cleaning of accumulated debris and improving the ease of debris removal.

[0031] Working principle: First, place multiple sets of connecting culverts 12 in the installation position in sequence. Insert the assembly pins 15 into the assembly holes 10 to connect the multiple sets of connecting culverts 12. Install the outer limiting rings 13 on the surfaces of the connecting culverts 12 at both ends. Install the culvert pier 1 on the surface of the connecting culvert 12 on one side of the outer limiting ring 13. The outer limiting ring 13 provides limiting support for one side of the culvert pier 1. Rotate the locking bolt 16. With the threaded connection between the locking bolt 16 and the threaded sleeve 17, the locking bolt 16 moves downward and extends to the surface of the top slide rail 8 to fix the inner limiting ring 14 to the top slide rail 8. Thus, the inner limiting ring 14 provides limiting support for the other side of the culvert pier 1. If the thickness of the culvert pier 1 is different, slide the inner limiting ring 14. The inner limiting ring 14 slides on the surface of the connecting culvert 12 to move the inner limiting ring 14 away from the outer limiting ring 13, thereby adapting to culvert piers 1 of different thicknesses. If it is necessary to adjust the thickness of the culvert pier 1... When protecting passing vehicles and pedestrians, loosen the locking pin 2 to separate the support column 3 and the movable sleeve 4, pull the guardrail 5 upward, and the guardrail 5 will drive the movable sleeve 4 to slide on the surface of the support column 3 to adjust the height of the guardrail 5. Then, tighten the locking pin 2 to connect the support column 3 and the movable sleeve 4 to adjust the height of passing vehicles and pedestrians for protection. Water flows through the salvage frame 25 into the interior of the culvert 11, where the filter screen 26 filters and collects debris. If a lot of debris accumulates on the surface of the filter screen 26, the handle 20 drives the rotating rod 21 to rotate, which in turn drives the worm gear 22 to rotate, which in turn drives the worm wheel 23 to rotate. The worm wheel 23 drives the salvage frame 25 and the filter screen 26 to rotate through the movable shaft 24, thus rotating the salvage frame 25 and the filter screen 26 from a vertical position to a horizontal position, making it easier to remove debris from inside the salvage frame 25, thereby completing the use of the prefabricated frame tunnel.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
