The invention discloses a portable measuring device with adjustable depth for geotechnical geological investigation. The portable measuring device comprises a bottom plate, wherein a through hole is formed in the middle of the bottom plate; a drilling sampling device is arranged above the through hole; the drilling sampling device comprises a first rotating shaft; a drill bit is arranged below thefirst rotating shaft; a plurality of connecting drill rods are arranged between the drill bit and the first rotating shaft; first flanges are arranged at two ends of the connecting drill rods; the connecting drill rods are correspondingly connected with the drill bit and the first rotating shaft through second flanges; first spiral blades are arranged on the connecting drill rods; cavities are formed inside the connecting drill rods; and rotating shafts are arranged inside the cavities. The portable measuring device has the beneficial effects that the device is simple in structure and convenient to operate and use, rock soil of different depths can be sampled by drilling at one time, mixing of rock soil of different depths during ascending is avoided, the use safety is greatly improved, the sampling accuracy is improved, and the sampling measurement accuracy is improved.
本发明公开了一种岩土地质勘察用深度可调的便携式测量装置，包括底板，所述底板的中间设有通孔，所述通孔上方设有钻孔取样装置，所述钻孔取样装置包括第一转轴，所述第一转轴的下方设有钻头，所述钻头与所述第一转轴之间设有若干连接钻杆，所述连接钻杆的两端均设有第一法兰，所述连接钻杆均通过第二法兰分别与所述钻头和所述第一转轴连接，所述连接钻杆上设有第一螺旋叶，所述连接钻杆的内部设有空腔，所述空腔的内部设有旋转轴。有益效果：该装置结构简单，方便操作使用，能够一次钻孔对于不同深度的岩土进行取样，避免上升时不同深度的岩土混合，大大的增加了使用的安全性，增加了取样的准确性，提高取样测量的精确度。
