Description

Technical Field

[0001] The invention relates to the technical field of rock stratum drilling for geological exploration, in particular to rock stratum drilling equipment for geological exploration. Background Art

[0002] Geotechnical engineering exploration is an important activity to identify, analyze and evaluate the geological, environmental characteristics and geotechnical conditions of the construction site, and to prepare exploration documents. This work is the basis of engineering design and construction, and its importance is self-evident. If the exploration work is not in place and the geological problems are not accurately revealed, even if the subsequent design and construction work meet high quality standards, the foundation and structure may still face the risk of damage. Therefore, ensuring the comprehensiveness and accuracy of the exploration is crucial to ensuring the quality and safety of the project. In addition, engineering activities of different types and scales during the exploration process will have different degrees of impact on the geological environment. How to reduce the negative impact on the environment while conducting efficient exploration is also one of the important challenges of geotechnical engineering exploration.

[0003] Rock drilling equipment is an important and commonly used tool, especially in the fields of mineral resource exploration, engineering construction and groundwater detection. Drilling equipment can collect samples or obtain geological information by drilling into underground rock formations. Existing rock drilling equipment has made certain progress in the past development, especially in improving drilling efficiency and durability. However, with the increasing requirements for geological environment and the emergence of complex geological conditions, existing equipment still faces many technical bottlenecks in application.
