[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 preparing investigation documents according to the requirements of the construction project.

[0003] In geotechnical engineering surveys, holes are drilled with a hollow drill bit to collect soil and rock layers at different depths in the hollow drill bit, and the samples are taken out for collection, which can facilitate professionals to effectively judge the soil quality, soil depth, rock layer structure, rock layer depth, etc. in the area. The existing sample collection box is provided with multiple arc-shaped grooves for collecting samples, and lacks necessary limits on the collected samples, resulting in internal samples being easily shaken and broken and mixed when the sampling box is transported, and the collected samples are difficult to take out quickly.
