Description

Technical Field

[0001] The utility model belongs to the technical field of soil-taking devices, in particular to a soil-taking device for geotechnical testing of geotechnical engineering. Background Art

[0002] Geotechnical testing is a general term for various tests conducted on rocks and soil for the purpose of engineering construction. Geotechnical testing is an important part of engineering geological survey. It is divided into sampling tests that separate rock and soil samples from their parent bodies and in-situ tests conducted directly on rock and soil bodies. Geotechnical sampling requires great attention to the quality of soil samples. During the drilling and soil sampling process, the structure of the soil is very easy to be disturbed. Testing with soil samples whose structure has been disturbed will inevitably lead to wrong conclusions, which will cause engineering accidents or waste construction funds. However, before conducting geotechnical testing, it is necessary to use a soil sampling device to take geotechnical samples.

[0003] The patent document with the prior art publication number CN217786578U provides a geotechnical engineering geotechnical test and detection soil taking device, including a box body, first cylinders are arranged on both sides of the box body, a collecting box is fixed on the right side of the box body, a second cylinder is symmetrically arranged on the top of the box body, and a suction pump is arranged on the corresponding side of the second cylinder. When the utility model is used, the suction pump is started to absorb the drilled soil into the elastic suction pipe with high pressure through the cooperation between the telescopic feed pipe and the elastic suction pipe, and the soil is transported to the discharge pipe through the telescopic feed pipe, so that the soil is directly transported to the inside of the collection box, so that higher quality soil can be collected to avoid waste of soil, and then the soil is discharged through the discharge pipe fitting by opening the discharge valve, so that it is convenient for staff to take soil for detection and testing work, and the device is flexibly moved by the setting of self-locking moving wheels, thereby solving the problem of manual downward pressure for drilling geotechnical operations, which is inconvenient to move and very time-consuming and labor-intensive.

[0004] However, during the use of the existing geotechnical engineering geotechnical test and detection soil sampling device, the soil sampling tube needs to be inserted into the rock and soil, and the rock and soil will enter the soil sampling tube. Because the rock and soil are compacted in the soil sampling tube and the soil itself has viscosity, when the rock and soil need to be taken out, the rock and soil are easily loosened, thereby affecting the sampling quality and the difficulty of sampling.

[0005] Therefore, those skilled in the art have proposed a geotechnical engineering geotechnical test and soil sampling device to solve the problems raised by the background technology. Utility Model Content
