Wiring construction method and device based on bailey truss

The invention discloses a Bailey truss-based wiring construction method and device, and the method comprises the steps: responding to a wiring construction request through a controller in a power operation vehicle, calling a detection radar to scan a current region, and obtaining cable wiring information; positioning the cable according to the cable wiring information, and removing soil and stones above and on the side of the cable; after the soil and stones are removed, a mechanical arm is called to erect the adjustable bailey truss in the current area according to cable wiring information in combination with a preset construction distance; the adjustable bailey truss is used as a support to suspend the cable; and after the soil and stones below the cable are removed, the mechanical arm is called to execute wiring operation below the cable. Therefore, a traditional steel structure is abandoned, the technical problems that according to a traditional scheme, the assembly process is tedious, meanwhile, assembly
