Embodiment Construction
[0033] The embodiments of the present invention are described below by specific specific embodiments. Those who are familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the present invention. , not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0034] like figure 1 As shown in the figure, the present invention provides a geological survey device, which can realize the function of directly taking out as much soil as the drilling depth through the cooperation of the spiral soil borrowing column 5 and the drilling casing 4, and also through the sweeping mechanism 8 to sweep away the gravel at the drilling position, so as to improve the service life of th...

The invention relates to the field of geological survey, and discloses a geological survey device. The device comprises a bearing frame and a soil taking mechanism connected to the center of the bearing frame in a penetrating mode. The top end of the soil sampling mechanism is connected with a driver. According to the invention, a spiral soil sampling column is matched with a drilling outer sleeve, the device achieves the function that the soil can be directly taken out according to the drilling depth; even if the soil viscosity of the drilled position is low, the situation that soil falls offdue to mechanical shaking in the soil taking-out process is not likely to happen; meanwhile, the length of the spiral soil taking column and the length of the drilled outer sleeve can be adjusted inreal time according to the spiral column and the separated sleeve, and therefore the application range of the equipment can be wider.
Description
technical field [0001] The invention relates to the field of geological survey, in particular to a geological survey device. Background technique [0002] "Geological exploration" refers to the investigation and exploration of the geology through various means and methods, to determine the appropriate bearing layer, to determine the foundation type and to calculate the basic parameters according to the bearing capacity of the bearing layer. Mineral deposits of industrial significance are found in the mineral census, in order to identify the quality and quantity of minerals, as well as the technical conditions for mining and utilization, to provide mineral reserves and geological data required for mine construction and design, and to analyze the rocks, strata, structures, Minerals, hydrology, landforms and other geological conditions are surveyed and researched. Usually, when conducting geological surveys, topographic surveys and land surveys are often carried out with the he...
