Description

Technical Field

[0001] The utility model relates to a drilling machine, in particular to an integrated rapid hole-forming device for dam soil layers. Background Art

[0002] With the development of economy, in order to develop and utilize river hydropower resources, it is necessary to take engineering measures on rivers or lakes. At present, most of the dams of rivers and lakes in my country have cracks, holes, ant holes and other problems due to their long construction history. Therefore, flood control embankments are needed in river and lake construction. Among them, drilling and grouting is the main reinforcement method, and drilling operations are mainly carried out by cone drilling machines.

[0003] Existing drilling cone probes have problems such as large size, difficult disassembly, and low drilling efficiency, and are mainly suitable for the dam top plane. On a longitudinal working surface parallel to the dam axis and on a slope, the verticality of the drilling cone probe does not meet the requirements, it is not easy to fix, and there are construction safety hazards. The machine moving process is cumbersome and only one hole can be drilled at a time, resulting in low drilling efficiency. Utility Model Content
