The rapid construction method comprises the following steps: preparing materials; cable inspection; preparation work; cable laying: a specific laying mode is determined according to field conditions, and a special construction scheme is compiled; when the cable enters and exits from a cable trench and a building, the access of a plate cabinet pipe is sealed by asphalt and hemp threads, when the cable is laid on a bracket, the distance between the brackets is not greater than 1.2 m, the bracket needs to be firmly bound, and the mounting and arrangement on the tray are straight; a leading-out wire of a cable terminal is kept at a fixed position, the binding length of the leading-out wire and an insulator is not less than 160mm, a cable terminal head is tightly bound and has no air leakage, a shielding grounding part with a lead bag needs to be firmly welded, the cable head and equipment need to be completely overlapped, a clamp is firm, and good grounding is ensured. According to the invention, the laying efficiency can be improved by preparing laid lines and materials in the early stage, the cable is clamped through the cable clamp, the cable is prevented from loosening during installation, and the effects of high installation efficiency, tightness, time saving and labor saving are achieved.
