[0033] See also Figure 1-3 A fully prefabricated assembly support structure for traffic track construction comprises a tunnel tube assembly 1 and a support mechanism 2 for supporting the tunnel tube assembly 1. The tunnel tube assembly 1 is supported by the support mechanism 2. The tunnel tube assembly 1 is formed by a combination of multiple arc-shaped plates. The support mechanism 2 comprises two rails 3 fixedly connected in the tunnel tube assembly 1. The rails 3 are arranged to facilitate the sliding of the support mechanism 2 thereon, thereby facilitating the adjustment of the position of the support mechanism 2 in the tunnel tube. The top outer walls of the two rails 3 are slidably connected with the same gantry 4. The outer walls on both sides of the gantry 4 are arranged with side support assemblies 5 for supporting the tunnel tube assembly 1. The top outer wall of the gantry 4 is arranged with a top support assembly 6 for supporting the tunnel tube assembly 1. The bottom outer wall of the gantry 4 is fixedly connected with two sliding seats 7. The bottom outer walls of the two sliding seats 7 are rotatably connected with roller shafts 8 in contact with the rails 3. The arrangement of the top support assembly 6 facilitates the support of the top of the tunnel tube. The side support assembly 5 facilitates the support of the two sides of the tunnel tube, thereby ensuring the stability of the tunnel tube. The arrangement of the roller shaft 8 facilitates the sliding of the sliding seat 7 on the rail 3.
[0034] Reference Figure 4-5 The top support assembly 6 includes a splicing seat 9, and the top outer wall of the splicing seat 9 is provided with four edges 10. The top outer wall of the door frame 4 is fixedly connected with four connecting columns 22 matching the edges 10. Through the cooperation between the connecting columns 22 and the edges 10, the top support assembly 6 is conveniently assembled on the door frame 4.
[0035] Reference Figure 4 and Figure 5 The top outer wall of the splicing seat 9 is fixedly connected with a fixing frame 11, and the top outer wall of the fixing frame 11 is provided with three sliding openings, and the inner walls of the three sliding openings are all slidably connected with a support frame 13, which is installed on the splicing seat 9 through the fixing frame 11, and the support frame 13 is convenient for sliding on the fixing frame 11.
[0036] Reference Figure 4-5The top outer walls of the three support frames 13 are fixedly connected with the same arc plate 14, and the arc plate 14 is in contact with the tunnel pipe assembly 1. The arc plate 14 is lifted and in contact with the top inner wall of the tunnel pipe, thereby facilitating the support of the tunnel pipe.
[0037] Reference Figure 5 Three groups of hydraulic cylinders 12 are fixedly connected to the inner wall of the bottom of the fixed frame 11, and the piston rods of the three groups of hydraulic cylinders 12 are respectively fixedly connected to the support frame 13. The setting of the hydraulic cylinders 12 facilitates the lifting of the support frame 13, and then facilitates the lifting and support of the arc plate 14.
[0038] Reference Figure 6 The side support assembly 5 includes an installation box 15 fixedly connected to the door frame 4, and a sliding opening is opened on the outer wall of one side of the installation box 15, and a sliding plate 16 is slidably connected to the inner wall of the sliding opening, and an arc block 17 that contacts the tunnel pipe assembly 1 is fixedly connected to one end of the sliding plate 16, and the arc block 17 is driven by the sliding plate 16 to be pressed against the inner wall of the tunnel pipe.
[0039] Reference Figure 6 The inner walls of both sides of the installation box 15 are rotatably connected with the same bidirectional screw 18, and the outer walls of the bidirectional screw 18 are screwed with threaded sleeves 19, and the rotation of the bidirectional screw 18 can conveniently drive the two threaded sleeves 19 to move toward or away from each other.
[0040] Reference Figure 6 The outer walls of the two threaded sleeves 19 are rotatably connected to the support plates 20, and one end of the two support plates 20 is rotatably connected to the sliding plate 16. The outer wall of one side of the installation box 15 is rotatably connected to a rotating part 21 with a regular hexagonal cross-section.

The setting of the rotating part 21 facilitates the rotation of the bidirectional screw 18, drives the threaded sleeves 19 to move, and then cooperates with the support plate 20 to drive the sliding plate 16 to move.
[0041] The implementation principle of the present application is as follows: when in use, the support mechanism 2 is first assembled outside the tunnel pipe, and the top support assembly 6 is assembled on the top of the gantry 4 directly through the cooperation between the connecting column 22 and the edge 10 on the splicing seat 9, and then the support mechanism 2 is conveniently sent to the position in the tunnel pipe that needs support through the roller shaft 8 on the sliding seat 7. When moving to the specified position, the hydraulic cylinder 12 is first started to push the support frame 13 to lift the arc plate 14. When the arc plate 14 is lifted, it is directly pressed on the top inner wall of the tunnel pipe assembly 1, and is connected to the rotating part 21 through an electric wrench. The driving rotation of the rotating part 21 directly drives the bidirectional screw 18 to rotate. When the bidirectional screw 18 rotates, it directly drives the two threaded sleeves 19 to move toward or away from each other. When the two threaded sleeves 19 move toward each other, the arc block 17 on the sliding plate 16 is directly pushed through the support plate 20 to press on the side wall of the tunnel pipe assembly 1, thereby ensuring the stability of the tunnel pipe assembly 1.
