Description
Technical field
The utility model relates to electrical power distribution technical field of construction, more particularly, relates to the cable fixture of a kind of cable shaft and junction, cable tunnel.
Background technology
In the laying technology of electrical power distribution field underground cable, be typically employed in vertical direction arranges cable shaft and offer in the horizontal direction cable tunnel combine and method wear to the underground realizing cable, and support can be adopted to solve the transition fixation problem of cable in both junctions at cable shaft and junction, cable tunnel.
In the existing stage, in electric power tunnel, the construction technique of cabling can face following two hang-ups:
1. along with the rapid growth of electricity needs, cable holding progressively increases and also makes cable size thicker; And the loop quantity of cable tunnel inner cable outlet is more, each time cable line is not in the same period built.Because vertical cable shaft and the cable tunnel of level are generally successively according to construction directly intersect and be connected through, space is worn with the cable forming the right-angled bend of a band in the underground space, therefore, all there is one section of unsettled transitional region to the fixture on cable shaft in the support in each telegram in reply cable route cable tunnel.This transitional region makes situation special due to band right-angled bend, is therefore difficult to the position at Tunnel Design stage unified planning support.
Existing operation is usually can only after the cable laying of each bid section completes, according to on-site cable stressing conditions, move towards and lay angle carry out analyzing and carry out secondary operations and welded and installed to support, carry out holding and the cable of fixing transitional region.But, current mode is adopted to solve the matching problem of support and cable, reduce the versatility of support to a certain extent and reduce the scope of application of support, thus cause this increase of resource input and engineering time to extend, also affect the arrangement space of later stage cabling to a certain extent, and cable stressing conditions cannot be adjusted and there is potential safety hazard.
2. because cable tunnel and ground height low head are large, turning during cable incoming-outgoing cable shaft is relatively more rapid, and the cable causing the later stage to be laid turns to the right-angled bend insufficient space at cable shaft place in cable tunnel; And cable shaft taking up room in underground to be considered in the erection of city, the diameter of cable shaft is made to have certain restriction, the requirement of turning of cable radius when therefore having the diameter of the cable shaft of size restrictions to be difficult to meet cable laying, thus directly affect laying and safe operation of cable line.
