Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering investigation, in particular to a geotechnical engineering investigation device capable of observing the soil penetration depth. Background Art

[0002] Geotechnical engineering investigation refers to the activities of identifying, analyzing, and evaluating the geological, environmental characteristics and geotechnical conditions of the construction site and compiling investigation documents according to the requirements of the construction project. Drilling sampling is required during the geotechnical engineering investigation, but the sampling depth is unclear. Therefore, it is necessary to observe the soil penetration depth of the sampling process to enrich the geotechnical engineering investigation data.

[0003] A Chinese patent discloses a geotechnical engineering survey sampling device (authorization announcement number CN218035760U). This patented technology uses a method of taking soil from the outside, and sets the soil taking method to a flip structure. When inserting the rock and soil, the sampling box is always in a storage state. Only after the drill bit is in place, the drill bit is opened. In the process of pulling the sampler outward, the rock and soil within the outer ring range of the sampler are taken out by relying on the sampling box in a barbed state. The operation is convenient and labor-saving, and rock and soil in different directions and at different depths of the insertion position can be taken out. However, the soil penetration depth of the above-mentioned geotechnical engineering survey sampling device cannot be accurately judged during the sampling process, and it needs to be judged based on the insertion depth of the sampling rod, which is not conducive to the accuracy of the geotechnical engineering survey data. The sampling rod and the downward pressure member are an integrated structure, which is not conducive to the replacement of the sampling rod. Manual sampling is required, and sampling is time-consuming and labor-intensive. Therefore, those skilled in the art provide a geotechnical engineering survey device that can observe the soil penetration depth to solve the problems raised in the above-mentioned background technology.
