Problems solved by technology

[0004] In order to overcome that the drilling and sampling work cannot be carried out simultaneously, if the side wall of the drilled hole collapses, the layering effect of the taken out samples is poor, and the representativeness of different depths is destroyed, which will eventually lead to the work progress of the geotechnical investigation work. slow, and cause a large deviation between the result data and the real data, the invention provides a drilling device with sample collection function for geotechnical engineering investigation

Embodiment 1

[0039] A drilling device with sample collection function for geotechnical investigation, such as Figure 1-Figure 10 As shown, it includes a ground drilling unit, a sample collection unit, a grinding unit, a main support 1, a lifting component 2, a drive motor 3, a vacuum generator 4 and a bottom support 5; the upper side of the main support 1 is connected with a lifting component 2; The middle part of the part 2 is fixed with a drive motor 3; the front side of the main support 1 is fixed with a vacuum generator 4; the lower side of the main support 1 is fixed with a bottom support 5; the lower side of the lifting part 2 is connected with a ground drilling unit; The output shaft of the drive motor 3 is connected to the ground drilling unit; the inner side of the ground drilling unit is connected with a sample collection unit; the vacuum generator 4 is connected to the sample collection unit through the suction pipe 41; the lower side of the ground drilling unit is connected wit...

Embodiment 2

[0051] like Figure 1-Figure 12 As shown, this embodiment is further optimized on the basis of Embodiment 1, and also includes an auxiliary sampling unit, the connecting block 107 is provided with an auxiliary sampling unit, and the auxiliary sampling unit includes a spring telescopic rod 401, an arc-shaped mounting plate 402 and the outer grinding plate 403; several spring telescopic rods 401 are fixed around the outer surface of the connecting block 107; an arc-shaped mounting plate 402 is fixed between the outer ends of two adjacent spring telescopic rods 401; each Several outer grinding plates 403 are welded to the outer surface of the arc-shaped mounting plate 402 .

[0052] The high-speed rotating drill bit 108 continuously drills the rock and soil to obtain rock and soil powder, and at the same time, the sampling pipe 301 captures the small-sized rock and soil powder floating around the drill pipe 106, so that the rock and soil powder is collected in the low-pressure st...

Abstract

The invention relates to the field of geological investigation, in particular to an intelligent drilling rig with a sample collection function for geotechnical engineering investigation. The technical problems that drilling and sampling work cannot be conducted synchronously, if the side wall of a drilled hole collapses, the layering effect of a taken sample is poor, and representativeness of the sample at different depths is damaged are solved. The drilling rig with the sample collection function for geotechnical engineering investigation comprises a drilling unit, a sample collection unit and the like, and the inner side of the drilling unit is connected with a sample collection unit. The fine collecting pipe for collecting samples is arranged in the drill rod, the vacuum generator generates low pressure in the collecting pipe, rock and soil powder is evenly sucked into the collecting pipe, and the drilling speed and time of the drill bit are controlled by the infrared distance measuring probe during the period. And the distribution state of the rock-soil samples at different depths collected in the collecting pipe is close to the real depth distribution state of the rock-soil samples at different depths.

Description

technical field [0001] The invention relates to the field of geological survey, in particular to an intelligent drilling device with sample collection function for geotechnical engineering survey. Background technique [0002] Geotechnical engineering investigation refers to the identification, analysis and evaluation of the geological and environmental characteristics of the target construction site and the geotechnical engineering conditions according to the requirements of the construction project. Distributed survey work to obtain the underground geotechnical distribution state map of the target construction site, from which to analyze the natural conditions of the underground topography, landform and hydrology of the construction area, to help the later construction planning. [0003] During the geotechnical investigation of the target construction site, it is necessary to carry out drilling and sampling work for the sampling sites of the target construction site succes...
