Background

With the increasing expansion of city construction scale, the power demand is increasing year by year, and each large city power grid faces the problem of how to accommodate more high-voltage transformer substations and power transmission lines under the conditions of limited land resources and tense line corridor channels so as to meet the increasing power consumption scale. Under the condition of the prior art, the traditional overhead line power transmission mode gradually quits the stage of urban power grid construction due to the reasons of occupying more urban land resources, having great influence on the environment, being limited by the electromagnetic radiation level and the like. Meanwhile, the power cable tunnel becomes an important solution for the construction of the power transmission line of the urban power grid due to the advantages of large transmission capacity, high reliability, easiness in intensive management and maintenance and the like.

In order to facilitate cable laying, working wells are required to be arranged at the turning, branching and intersection positions of the cable path of the tunnel. At present, the cable support in a working well is fixed in a traditional mode, and once the cable support is installed, the height, the number of layers and the cable laying angle of the support cannot be adjusted. In the cable tunnel working well, the available space size is limited, the number of the support layers is often required to be temporarily increased or reduced during construction and operation and maintenance, and meanwhile, the horizontal or vertical direction of a cable is adjusted, so that the conventional fixing support cannot meet the requirement of flexible adjustment. If the fixed support is removed and the design and installation are carried out again, the problems of increased cost, inconvenient construction, easy damage to auxiliary facilities in the tunnel and the like can be caused. Simultaneously, the cable body singleweight is great and the cost is expensive, easily collides with fixed bolster, supervisory equipment etc. when the construction is carried, leads to the cable impaired.
