Undisturbed soil exploratory well sampling robot

Abstract

The invention discloses an undisturbed soil exploratory well sampling robot. The sampling robot comprises a first winch, a second winch, a sampling robot body and a sample frame, wherein the first winch and the second winch are installed on the ground, the sampling robot body cooperates with the first winch and extends into an exploratory well, and the sample frame cooperates with the second winchand is down-placed onto the sampling robot body. According to the sampling robot, fixation between the sampling robot and the exploratory well is realized through expansion of a supporting air bag; asoil sample is acquired stably and accurately by the adoption of a sampling mechanism through robot channeling sampling; a balancing air bag is utilized to balance disturbance of the soil sample on the sample frame in the lofting process; a worker can take out undisturbed soil on the premise of not entering the well, so that the personal safety of the worker is guaranteed; and the sampling robotis small in size, low in weight and high in intelligent level and can be widely used for sampling all kinds of soil masses to provide excellent research samples for scientific research design.

Description

technical field [0001] The invention belongs to the technical field of undisturbed soil exploration well sampling, and in particular relates to an undisturbed soil exploration well sampling robot. Background technique [0002] At present, in engineering and scientific research work, because soil samples taken mechanically will disturb the soil, in order to obtain the real physical and mechanical indicators of the soil, it is usually necessary to take exploratory well samples in the field. General exploratory well sampling is to use Luoyang to shovel the well to the design depth, then enter the underground well by experienced workers, and carve undisturbed soil samples of different depths on the well wall from top to bottom (generally, the diameter or side length is 20 centimeters to 30 centimeters), and then store in wax seals or directly conduct on-site physical index tests; exploratory well sampling has little effect on soil disturbance, and its test data is relatively mor...

Problems solved by technology

General exploratory well sampling is to use Luoyang to shovel the well to the design depth, then enter the underground well by experienced workers, and carve undisturbed soil samples of different depths on the well wall from top to bottom (generally, the diameter or side length is 20 centimeters to 30 centimeters), and then store in wax seals or directly conduct on-site physical index tests; exploratory well sampling has little effect on soil disturbance, and its test data is relatively more accurate, but this method has a greater potential safety hazard , especially as the excavation depth increases, the hidden dangers also increase

Casualties caused by workers working underground are not uncommon in engineering, such as falling gravel at the wellhead, suffocating to death due to lack of oxygen in the well, and even the well wall collapsed and buried. These hidden dangers have caused great harm to the personal safety of workers.
