The cable is mainly used in cooperation with the underground pipeline for long-distance buried power supply, and is convenient for electric power operation and maintenance personnel to carry out daily cable operation and maintenance and fault maintenance.

Along with the further development of urbanization construction, the height of the well neck of the existing working well is lower than the horizontal plane of the road by the urban road transformation and the integral lifting of the ground of the later-stage residential area, and further lifting treatment is needed. The existing working well height-lifting treatment method is mainly characterized in that upward manufacturing is continuously carried out on the basis of the existing working well, and a reinforced concrete structure or a masonry structure and the like are generally adopted. The brick body working well has high requirements on labor force technology, (the process cannot be guaranteed, the strength cannot be achieved), and the service life is short; the construction process of the cast-in-place reinforced concrete manhole is complicated, and a plurality of processes such as erecting templates, binding reinforcing steel bars and the like are needed; therefore, the traditional working well is long in lifting construction time, large in labor force demand, large in construction environmental influence, difficult to guarantee construction quality and high in later maintenance cost.

Therefore, it is desirable to provide a device for raising the neck of a working well, which can solve the above technical problems.
