Description

Sand sampler for rock and soil investigation Technical Field The utility model relates to the field of rock and soil exploration, in particular to a rock and soil exploration sand remover. Background Geotechnical investigation refers to a series of early investigation activities performed during engineering construction. The method mainly comprises the steps of surveying, analyzing and evaluating the site of the construction project, and judging the feasibility and rationality of the construction project according to the conditions of regions, environments and the like. In the process of rock and soil exploration, various sampling tools are often required to acquire real information of an underground soil layer, wherein a sand sampler is a tool special for sand layer sampling, and can penetrate into the underground to acquire a sand sample which is kept in an original state, so that engineers are helped to know various parameters of the sand layer. For example, patent document CN222364794U discloses a sand sampler for rock and soil investigation, which comprises a sampling tube, a casing, a cavity defined in the casing, an opening communicated with the cavity, four storage grooves spaced on the peripheral side wall of the casing, four fixing plates respectively arranged in the four storage grooves, a first driving mechanism arranged in the cavity and a second driving mechanism arranged in the cavity, wherein the bottom ends of the fixing plates are rotatably connected with the storage grooves through a first shaft body, and the fixing plates are in a folded or unfolded form on the casing. According to the device, the first driving mechanism enables the fixing plate to be in the unfolded state so as to fix the shell, the second driving mechanism controls the sampling tube to conduct sampling operation, and after the sampling operation is finished, the first driving mechanism is operated to enable the fixing plate to be restored to the folded state, so that the occupied area of the fixing plate is reduced, and the device is convenient for a user to carry. In the prior art, most sampling structures adopt sampling tubes with openings at the bottom or sampling barrels with openings at the side, but due to strong mobility of sand, the sampling structures with openings at the bottom can cause a large amount of loss, and the sampling structures with openings at the side can bring disadvantages of difficult sample taking and sample confusion, so the application provides a sand remover for avoiding the disadvantages.
