A method of exploration well sampling based on undisturbed soil exploration well sampling robot

Abstract

The invention discloses an exploration well sampling method based on an undisturbed soil exploration well sampling robot. The method comprises the steps of: 1. determining the position of the soil sample; 2. obtaining the exploration well; 3. lowering the sampling robot; 4. fixing the sampling robot and adjusting the sampling robot 5. Lowering the sample frame; 6. Obtaining soil samples; 7. Staking out soil samples; 8. Transporting soil samples; 9. Shifting the sampling robot. The invention uses the expansion of the support airbag to realize the fixation between the sampling robot and the exploration well, uses the robot to cut the groove for sampling, adopts the sampling mechanism to obtain the soil sample stably and accurately, and uses the balance airbag to balance the disturbance of the soil sample to the sample frame during the stakeout process, which can make workers Under the premise of not entering the well, the undisturbed soil is taken out to ensure the personal safety of workers. It is small in size, light in weight, and highly intelligent. It can be widely used for sampling various types of soil and provides high-quality research samples for scientific research and design. .

Description

technical field [0001] The invention belongs to the technical field of undisturbed soil exploration well sampling, and in particular relates to an exploration well sampling method based on 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 dis...

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.
