Embodiment Construction

[0014] 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.

[0015] 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 ring cable support 200 is connected with the cable fixing clamp 300 along the circumference, and the cable fixing clamp 300 clamps the large cross-section cable 400 . The inner space of the circular cable tunnel 100 (the lower part of the circular cable tunnel 100) is provided with a pedestrian corridor 500, the pedestrian corridor 500 is provided with a low-voltage control cable 600, and the inner space of the circular cable tunnel 100 is also provided with a horizontal cable arrangement frame 700 and / or the vertical cable arrangement f...

Abstract

The invention discloses tunnel ring-shaped layout of a cable with a large cross-section, which comprises a cable tunnel with a circular section. Along the periphery of the circular cable tunnel, the cable is arranged; the cable tunnel is provided with ring-shaped cable brackets in the axial direction and at intervals; the ring-shaped cable brackets are connected with cable fixing clamps; and the cable fixing clamps are used for clamping the cable. The structure of the ring-shaped layout overcomes the defect of adopting the inner space of the tunnel of the original cable tunnel layout, and the cable is arranged along the inner wall of the circular tunnel. On one hand, the circumferential perimeter is fully used for the cable layout, thereby increasing the cable layout loop. On the other hand, the inner space of the tunnel is released, thereby increasing the utilization rate of the inner space of the tunnel. The released inner space of the tunnel can be used for cable layout again (horizontal layout or vertical layout), and simultaneously can be used as the walkway, and is convenient for maintenance.

Description

technical field [0001] The invention belongs to the arrangement structure of large-section cables, and in particular relates to an arrangement structure of large-section cables in a circular tunnel. Background technique [0002] Power cable tunnels mainly have the following types: excavated tunnels, excavated tunnels, pipe-jacking tunnels, and shield tunnels. The cross sections of the first two types of tunnels are mainly rectangular, while the latter two are mainly circular. The layout of cables is mainly traditional horizontal layout and vertical layout. The horizontal layout is to use the width of the tunnel; the vertical layout is to use the height of the tunnel; both of these two layouts are arranged by using the inner space of the tunnel, so that the inside of the tunnel is occupied, the cable layout circuit is less, and the maintenance in the tunnel is occupied. space. In a tunnel with a circular cross-section, this arrangement makes the number of loops for laying ...
