Problems solved by technology

At present, the mechanical structure of drilling and anchoring is generally large-scale, and the operation is not automatic enough, requiring more manual participation, and it is impossible to complete the drilling work on the inner wall of the pipeline in a narrow space. This structural design can solve this problem and is suitable for narrow and long pipelines The drilling work of the inner wall is light and intelligent, and basically does not require too much manual participation

Description

technical field [0001] The invention relates to the technical field of rock mechanics model test equipment, in particular to a device for drilling deep holes on the side wall of a pipeline. Background technique [0002] In modern society, many engineering projects need to be constructed in deep holes, or need to excavate pipelines. Considering possible subsidence and high construction costs during pipeline excavation, it is necessary to conduct simulation experiments on the deformation and failure characteristics of the rock and soil around the pipeline and the entire excavation process before the project starts. The internal bolt support provides preliminary technical support and proposes a scientific and reasonable support plan. [0003] At present, most pipeline robots are detection robots, which can detect problems but cannot solve them. The usual construction scheme tends to bolt support, which uses the mechanical properties of the rock and soil around the pipeline to...
