Description

Technical Field

[0001] The invention relates to the field of rock mass engineering investigation, and in particular to a drilling device and method for rock and soil construction investigation. Background Art

[0002] Geotechnical engineering is about solving rock and soil engineering problems, including foundations, slopes and underground engineering. Geotechnical engineering surveys often require drilling to obtain geological information.

[0003] Rock exploration is the process of detailed investigation and analysis of underground rocks to obtain information about the properties, composition, structure and characteristics of the rocks. Key technologies include drilling technology, geophysical exploration, etc. The main features of these technologies and methods include: Drilling technology: By drilling underground, rock samples are obtained for laboratory analysis to understand the physical properties, chemical composition and pore characteristics of the rocks; Geophysical exploration: By measuring underground physical field parameters such as seismic wave propagation speed, electromagnetic field changes, gravity and magnetic field characteristics, etc., the properties and structure of the rocks can be inferred; In summary, the comprehensive application of rock exploration technologies and methods can provide comprehensive rock information and provide important basis for geological research, mineral resource exploration, engineering construction and environmental assessment.

[0004] A drilling device and drilling process for geotechnical engineering investigation disclosed in Chinese patent CN112324355A, wherein the drilling device includes a frame, a drill rod and a plurality of legs, the drill rod and the legs are connected to the frame for lifting and lowering, a first driving member for driving the drill rod to rotate is connected to the frame, and a linkage mechanism for driving the legs to lift and lower is also connected to the frame.

[0005] However, compared with the prior art and the comparative scheme, it can be seen that the drilling device still has the following problems during actual use: When there are many potholes on the rock surface where the device is placed, the device will shake and tilt. When the part that needs to be drilled for exploration is located in a non-horizontal position such as a slope, it is not convenient to adjust the drilling device horizontally, which can easily lead to the drill rod being skewed. The skewed drill rod can easily lead to poor drilling quality of the exploration hole, which can ultimately affect the accuracy of the exploration results. Summary of the invention

[0015] Preferably, the number of the connecting ball, the second sliding member, the connecting column, the limiting plate, the elastic member and the anchoring nail are two each.

[0016] A method for using a drilling device for geotechnical construction investigation comprises the following steps: S1: When the location to be drilled and surveyed is located on a slope, the third screw is rotated by the adjusting head, the third screw drives the connecting shell to move, the connecting shell drives the connecting column through the second sliding member, the connecting column drives the anchor nail to move through the limit plate, and the anchor nail is inserted into the ground to fix the device; S2: Adjust different fixing components according to the inclination angle of the slope to ensure the level of the support frame, thereby avoiding the situation where the drill rod is skewed during the drilling and survey of the drilling component, ensuring the quality of the survey borehole, and thus ensuring the accuracy of the drilling and survey results; S3: before drilling and surveying, start the first driving member and the second driving member, the first driving member drives the first moving frame to move through the first screw, the second driving member drives the second moving frame to move through the second screw, and the second moving frame drives the drilling assembly to move, so as to adjust the position of the drilling assembly; S4: When the drilling assembly moves to a position where drilling and investigation is required, the first driving member and the second driving member are turned off, and the third driving member is started.

Since the potholes on the ground are not evenly distributed, the ground levels at the locations where the different anchoring nails are located are not the same; S7: After the limit plate on the anchor nail at a relatively high level contacts the ground, the limit plate pushes the connecting ball upward through the connecting column, and the connecting ball pushes the connecting ball corresponding to the relatively low level position downward through the first sliding member; S8: The connecting ball corresponding to the position with a relatively low horizontal height pushes the connecting column corresponding to the position with a relatively low horizontal height, and the connecting column corresponding to the position with a relatively low horizontal height drives the anchor nail corresponding to the position with a relatively low horizontal height to move downward through the limit plate, and is inserted into the ground at the position with a relatively low horizontal height, ensuring that the anchor nails at different positions can be inserted into the ground to fix the device, thereby avoiding shaking or tilting of the device when used in places with many potholes, ensuring the stability of the device during drilling and investigation, and thus ensuring the effect of drilling and investigation.

[0017] Compared with the prior art, the present invention has the following beneficial effects: When the location where drilling and exploration is required is on a slope, different fixing components can be adjusted according to the inclination angle of the slope to ensure the level of the support frame, thereby avoiding the drilling and exploration from being skewed, ensuring the quality of the exploration borehole, and ensuring the accuracy of the exploration results. When there are many potholes at the location where drilling and exploration is required, it can ensure that the anchor nails at different positions can be inserted into various parts of the ground with uneven horizontal heights to fix the device, thereby avoiding shaking or tilting of the device when used in a place with many potholes, ensuring the stability of the device during drilling and exploration, and thus ensuring the effect of drilling and exploration.
