Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil and rock sampling technology, and in particular to a soil and rock sampling drilling machine for geological testing. Background Technology
[0002] Soil and rock sampling is an indispensable basic step in geological exploration and engineering construction. Its core objective is to obtain information on the original physical state and chemical composition of underground soil and rock masses through scientific methods. As the direct product of this process, rock cores carry the key codes of stratigraphic evolution. During drilling, the cylindrical rock cores formed by the drill bit cutting through soil and rock layers not only visually present geological features such as sedimentary patterns and fault structures, but the pore water and gas components encapsulated within them are also important evidence for analyzing paleoclimate and underground pollution.
[0003] Modern soil and rock sampling technology has broken through the traditional single sampling mode. Through diverse methods such as rotation, impact, or static pressure sampling, combined with in-situ testing devices and intelligent monitoring systems, parameters such as pore water pressure and shear strength at the sampling point are recorded simultaneously while extracting the rock core. This ensures the integrity of the rock core and the multidimensional verification of related data, providing an accurate "stratigraphic archive" for subsequent soil and rock mechanics analysis.
[0004] Patent document CN222105111U discloses a soil and rock sampling device, including a support plate. A sampling rod is fixedly connected to the lower surface of the support plate, and a sampling cylinder is fixedly connected to the lower end of the sampling rod. A controller is fixedly connected to the upper surface of the support plate, and a telescopic structure is provided on the upper surface of the controller. The telescopic structure includes a base fixedly connected to the upper surface of the controller, and a telescopic cylinder fixedly connected to the upper end of the base. The telescopic cylinder has a frustum-shaped structure. A connecting strip is fixedly connected to the side wall of the controller, and a sliding rod is slidably connected inside the connecting strip. A connecting ring is fixedly connected to the upper end of the sliding rod, and the connecting ring is fixedly connected to the upper end of the telescopic cylinder. This utility model, by setting a telescopic structure, facilitates the flexible weight-adding operation of the soil and rock sampling device, facilitates the sampling of deep, hard soil, and to a certain extent reduces the difficulty for workers sampling deep, hard soil.
[0005] In the prior art of the aforementioned patent, when the sampling tube is pulled upwards after sampling, the rock core inside the sampling tube is prone to slipping. The slipped rock core will fall back into the hole below the sampling tube, causing inconvenience to the sampling process. Utility Model Content
