Description

Technical Field

[0001] The utility model belongs to the technical field of soil sampling equipment, and in particular relates to a layered sampling device for rock and soil construction. Background Art

[0002] In the existing layered sampling device for geotechnical construction, other rocks and soils will enter the sampling tube when drilling into the ground, which makes it easy to confuse the sampling. It is also not convenient and labor-saving when drilling into the ground for sampling, resulting in low work efficiency. In addition, when taking out the sample, the contact area between the push block and the sample is small, which makes the sample integrity low, and the broken sample is easily mixed together, which makes the subsequent analysis difficult. Among them, the "layered sampling device for geotechnical construction" disclosed with the application number "CN202020770167.7" is also an increasingly mature technology. Through the provided push rod, connecting rod and push block, when the sampling is completed, the staff holds the grips on both sides of the sampling tube and pulls out the sampling tube drilled into the ground with force. Then the staff inserts the push block at the bottom of the push rod downward from the top of the sampling tube into the sampling slot, and then holds the grip rod and push rod and forces them together, so that the push rod pushes the rock and soil sample in the sampling slot through the connecting rod. The outer diameter of the push block is the same as that of the push block. The inner diameter of the sampling groove is adapted to increase the contact area between the push block and the sample in the sampling groove, so that the integrity of the sample is high after being pushed out. However, the device has the following defects: in actual use, manual handheld equipment is still required to drill the ground, and it is easy to drill off-center when drilling downward for sampling, resulting in position offset, affecting the drilling sampling depth and drilling accuracy. At the same time, the sample needs to be manually removed after drilling, and clay is easy to stick to the inside of the sampling tube, which is not convenient for cleaning the remaining sample. After cleaning, the sample is not convenient for segmented processing according to the drilling depth. Utility Model Content
