DETAILED DESCRIPTION
[0014] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.
[0015] Embodiment: a tunnel edge arch side wall multifunctional support, like Figs. 1-2As shown, the outer surface of the multifunctional support can be provided with an insulating layer (not shown in the figure) to avoid leakage accidents caused by contact between cables and the multifunctional support. The multifunctional support for the side wall of the tunnel side arch comprises a support column 1. The lower part of the support column 1 is an arc-shaped section 2, and the upper part of the support column 1 is a straight section 3. The arc-shaped section 2 is arc-shaped, which can reduce the distance between the support column 1 and the side arch when the support column 1 is inclined to the side arch, thereby avoiding the influence of the support column 1 on the movement of the trolley or other construction after the support column 1 leans against the side arch. The cross section of the support column 1 is rectangular. The upper part of the support column 1 is provided with a support cross bar 6. The support column 1 is connected to the support cross bar 6 through the straight section 3. An extension structure 4 is arranged on the straight section 3. The extension structure 4 allows the straight section 3 to be conveniently adjusted in length. The extension structure 4 comprises an inner sleeve 5 fixedly connected to the lower part of the support column 1 and an outer sleeve 7 fixedly connected to the support cross bar 6. The inner sleeve 5 and the outer sleeve 7 are matched and arranged. The inner sleeve 5 and the outer sleeve 7 are connected through positioning bolts 8. The inner sleeve 5 is uniformly provided with positioning holes 9 at the upper position. The outer sleeve 7 is provided with positioning holes 10 matched with the positioning holes 9. The positioning holes 9 and the positioning holes 10 are connected through the positioning bolts 8. When the height of the support column 1 needs to be adjusted, the positioning bolts 8 are loosened, the positions of the positioning holes 9 and the positioning holes 10 are adjusted, and the positioning bolts 8 are tightened after the length is adjusted to the appropriate length. The support cross bar 6 is hollow. The front and back surfaces of the support cross bar 6 are uniformly and throughly provided with wire holes 11. The wire holes 11 are convenient for threading cables and the like. The back surface of the support cross bar 6 is uniformly and fixedly provided with rubber protrusions 12. The number of the rubber protrusions 12 is two. The cross section of the rubber protrusion 12 is circular. The rubber protrusion 12 is a long strip-shaped structure, which extends from one end of the support cross bar 6 to the other end. The rubber protrusion 12 can avoid friction and indentation between the support cross bar 6 and the tunnel wall when the support cross bar 6 supports the tunnel wall, thereby playing a role in protecting the tunnel wall. A communication base station 13 (existing communication equipment) is arranged on the upper middle part of the support cross bar 6. A lighting lamp 14 is arranged on the left side of the support cross bar 6, and an emergency lamp 15 is arranged on the right side of the support cross bar 6. The communication base station 13 can cover the signal in the tunnel, thereby facilitating internal and external communication. The lighting lamp 14 is used for lighting in the tunnel. The emergency lamp 15 is used for emergency lighting after power failure in the tunnel. A support rod 16 is fixedly arranged on the upper part of the support cross bar 6. The communication base station 13 is arranged on the inner side of the support rod 16. The support rod 16 comprises a rectangular rod 17 and a "claw" shaped rod 18. The lower end of the rectangular rod 17 is fixedly connected to the upper surface of the support cross bar 6. The bottom end of the "claw" shaped rod 18 is fixedly connected to the top of the rectangular rod 17. The top of the "claw" shaped rod 18 is provided with an inverted "J" shaped camera support rod 19. The rectangular rod 17 and the "claw" shaped rod 18 are used for supporting the inverted "J" shaped camera support rod 19.The end of the inverted "J" shaped camera support rod 19 is provided with a camera 20; the front of the support column 1 is uniformly provided with hooks 21, the number of hooks 21 is at least four, the hooks 21 are uniformly distributed on the front of the support column 1 from top to bottom, the hooks 21 can be used for hanging water pipes, cables, optical fibers and the like, the lower end of the support column 1 is provided with a support leg 22, a reinforcing rib is arranged between the support leg 22 and the support column 1, so as to ensure that the support leg and the support column are connected firmly. The support leg 22 is arranged in an "eight" shape. A multifunctional support is placed at a distance of 5-10 meters in the tunnel, which is used for combing various lines in long distance and narrow space tunnels, meeting various requirements such as water supply, power supply, communication and lighting in the tunnel, and has strong practicality.
