Abstract:

Due to the complex environment and the inconvenient transportation, it is difficult to transport large-scale mechanical equipment to the operation site for the foundation of transmission line towers in mountainous areas. Therefore, manual pile foundation digging are widely used. In order to promote the mechanization of whole process of transmission line construction, a set of lightweight modular drilling rigs is designed. The overall structure of the proposed drilling rig and the performance parameters of each module are introduced. Combined with key technologies such as hydraulic system, electronic control system, intelligent display and remote control system of the proposed drilling rig, the structural design and theoretical calculation methods are used to realize the rapid assembly and disassembly of drilling rig, high-power drilling, drilling process parameter visualization, online monitoring, remote control and other functions, which effectively improves the safety of construction process. According to the requirements of micro-pile hole-forming, the on-site hole-forming test is completed. The results show that the proposed drilling rig has obvious advantages in the construction of micro-pile hole-forming for transmission lines in mountainous areas, which provides the support of hole-forming equipment for the construction of mountainous transmission lines with complex terrain, and provides experiences and methods for the future researches on the same type of equipment and technology.
