Embodiment
[0077] If the handle 3 and the fixed sleeve 4 total length are 70cm, the length of each movable sleeve 11 is 1m, and the total length of the soil removal thin rod 2 is 85cm, and the soil removal piston 16 cylinder height is 3cm, and the soil removal piston 16 The length of the cylindrical rod is 10cm, and the total length of the drill bit 12 is 30cm; then, when the depth is 3m, soil sampling needs to be carried out between the fixed sleeve 4 and the drill bit 12 or between the fixed sleeve 4 and the soil-taking drill bit 18. Add two movable sleeves 11.

The invention discloses a multifunctional and portable manual soil taking drill, which comprises a fixed sleeve, a holding handle horizontally arranged and fixedly connected to the upper end of the fixed sleeve, and a drill bit or a soil sampling drill bit detachably connected to the lower end of the fixed sleeve. When the drill bit is detachably connected to the lower end of the fixed sleeve, a soil discharging fine rod is further arranged in the fixed sleeve in a penetrating mode. A soil discharging handle is horizontally and fixedly arranged at the upper end of the soil discharging fine rodthrough a handle. A soil discharging piston is arranged in the drill bit, and the lower end of the soil discharging fine rod extends out of the fixed sleeve and abuts against the soil discharging piston. The invention relates to the multifunctional and portable manual soil taking drill. By means of the multifunctional and portable manual soil taking drill, the problems that in the prior art, manual drill bit soil discharging consumes much manpower and time can be solved. The invention further discloses a soil taking method adopting the manual soil taking drill.
Description
technical field [0001] The invention belongs to the technical field of water conservancy engineering test equipment, and relates to a multifunctional portable manual soil-borrowing drill, and also relates to a soil-taking method using the manual soil-borrowing drill. Background technique [0002] Soil drills are widely used in geotechnical, geological, water conservancy and other fields, and are the main tools for collecting soil samples. Manual drills are simple in structure, light in weight, and easy to carry. Most of them do not need transportation tools and are suitable for field experiments. [0003] When using manual soil extraction drill to drill holes, it is found that the problem of drill bit dumping is more difficult. The soil that enters the drill bit during drilling can only be removed manually, which consumes manpower and time, and seriously affects the progress of the test. In addition, to analyze the soil properties, it is also necessary to collect on-site so...
