Abstract

The present invention relates to a kind of digging system suitable for pipeline and line maintenance digging operation and operating in several kinds of digging modes. The digging system includes excavator, special precise digging dull teeth, pressure regulator, depth measuring warning unit and high pressure jetting unit. The safe digging process includes preparation, electronic intelligent digging preparation, pre-digging, precise digging, jet digging near pipeline and line, coarse digging, tailing and other steps.

Description

Technical field [0001] The pipeline safety excavation system and the pipeline safety excavation method of the present invention relate to a comprehensive equipment suitable for pipeline maintenance and excavation operations, and an operation method that combines multiple excavation methods. Background technique [0002] For a long time, the maintenance and excavation of optical cables have mainly relied on manpower, which is inefficient and labor-intensive. The operation and maintenance units usually hire migrant workers temporarily, which brings about the problems of poor controllability and manageability. The excavation process has become a major bottleneck in improving maintenance efficiency and strengthening the controllability of maintenance quality. The same problem exists in the maintenance of buried cables and municipal pipelines. With the advancement of operation and maintenance modernization, the need for mechanization of pipeline maintenance and construction excavation...
