[0002] According to regulations, the cable diameter exceeds 1000mm 2 , it is necessary to add snake laying in the project of casting. The existing cable snake laying methods include vertical snake laying and horizontal snake laying. Both of them have been proved to be safe and reliable in actual engineering design and operation, but these two Both laying methods are applied in rectangular tunnels. These two laying methods require a lot of labor and can only be completed with the assistance of machinery during the construction process.
However, for a new type of circular arrangement of cables, that is, in the circular arrangement of cables along the circular tunnel wall, there is no prior art for how to realize serpentine laying. The existing vertical serpentine laying and horizontal serpentine laying Neither can realize the serpentine laying of cables arranged in a ring

Embodiment Construction
[0015] This embodiment is used to explain the claims of the invention, and the protection scope of the present invention is not limited to the following embodiments.
[0016] Such as figure 1 As shown, a cable tunnel 100 with a circular cross section is spliced by tunnel pipes, and an annular cable support 200 is arranged between the two tunnel pipes. The annular cable support 200 protrudes from the tunnel wall and is inside the tunnel. The large-section cable 400 is wound on the cable reel 402; one end of the cable tunnel 100 is provided with a cable traction device 600, the large-section cable 400 is pulled by the cable traction device 600 through a traction rope 601, and the other end of the cable tunnel 100 is provided with a cable conveyor 500, The large-section cable 400 enters the cable tunnel and pulls out the cable tunnel through the cable turning wheels 401 at both ends of the tunnel.
[0017] Such as figure 2 As shown, a cable guiding device 700 and a cable fix...

The invention discloses a cable snakelike laying method which tows a cable over a tunnel from one end of the cable tunnel to the other end of the cable tunnel through a cable towing device. Cable guiding devices are arranged in the tunnel at intervals, and the adjacent cable guiding devices are arranged on the wall of the tunnel along the axial direction through an upper-down staggered way; the cable snakelike laying can be achieved through the way that the cable bypasses above the upper cable guiding device after bypassing below the adjacent lower cable guiding device; after the cable passes through the tunnel, a cable fixing device on the wall of the tunnel is utilized to fix the cable; the cable guiding devices are dismantled and are then connected and installed on the laying position of next cable; and the annular arrangement and the snakelike laying of the cable along the wall of the tunnel can be realized through repeatedly towing and laying the cables. The invention has high automation degree, and the snakelike shape can be automatically formed after the cables are laid, thereby the labor intensity of cable laying can be greatly lightened.
Description
technical field [0001] The invention belongs to a laying method in a cable tunnel, and in particular relates to a method for automatically forming a serpentine laying of cables under the action of mechanical traction. Background technique [0002] According to regulations, the cable diameter exceeds 1000mm 2 , it is necessary to add snake laying in the project of casting. The existing cable snake laying methods include vertical snake laying and horizontal snake laying. Both of them have been proved to be safe and reliable in actual engineering design and operation, but these two Both laying methods are applied in rectangular tunnels. These two laying methods require a lot of labor and can only be completed with the assistance of machinery during the construction process. However, for a new type of circular arrangement of cables, that is, in the circular arrangement of cables along the circular tunnel wall, there is no prior art for how to realize serpentine laying.
