Soil core sample sampling device for engineering geological investigation

Abstract

The invention discloses a soil core sample sampling device for engineering geological investigation, relates to the technical field of soil sampling devices, and solves the problems that an existing direct insertion type sampling device is poor in soil breaking performance and a rotary drilling type sampling device cannot sample a plurality of samples at the same time. The soil core sample sampling device for engineering geological investigation comprises device drilling rods, and the drilling rods are inserted into transmission cylinders. According to the device, the transmission cylinders drive the drilling rods to rotate; the drilling rods can rotationally drill into soil for sampling; the ground breaking performance is high, the problem that a traditional direct insertion type samplingdevice is poor in ground breaking performance is solved; and the device can synchronously drive four transmission cylinders to rotate at the same time through a driving motor, so that the device canobtain four samples at a time, the problems that a traditional rotary drilling-in type sampling device can only obtain one sample at a time, and the workload is large are solved, and the adaptabilityand practicability of the device are improved.

Description

technical field [0001] The invention belongs to the technical field of soil sampling devices, and more specifically relates to a soil core sample sampling device for engineering geological survey. Background technique [0002] Engineering geological survey is a geological survey and research work to find out the geological factors affecting engineering buildings, natural geological phenomena and natural building materials, etc. These are usually called engineering geological conditions. To predict the structure and operation characteristics of objects, and to predict the mode, characteristics and scale of the interaction between engineering buildings and engineering geology. At present, when conducting geological survey work, it is generally necessary to take samples for observation and research. [0003] For example, in the patent with the application number: CN201711281458.90, a soil layered rapid sampling device is disclosed, which includes a support, and a sampling mecha...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a soil core sample sampling device for engineering geological survey, to solve the problem that the existing in-line sampling device for geological survey is directly inserted into the soil for sampling, and the soil breaking performance is relatively poor. It is difficult to insert, and the rotary drilling type sampling device can only sample one sample at a time, and cannot sample multiple samples at the same time. When sampling the same part for multiple times, it needs repeated operations to obtain multiple samples. It is difficult to take out samples, the workload is heavy, and the adaptability and practicability are not high.
