Small Fried Dough Twists drill (small spiral soil drill, small soil lifting drill) is used for drilling in soft soil areas1–5Disturbed soil samples or drilling within meters1–5riceShallow hole.
The soil sampling drill is one of the main simple manual tools for shallow soil sample collection in geological surveys, industrial and civil construction fields. Reliability, ease of operation, and maneuverability of soil sampling drills,
Not only can it reduce the workload of soil investigation,Improve soil extraction efficiency,And it can also expand the adaptability of soil sampling.
1. Drill bit:Φ35*25*1m (welding)A diameter of 25mm rod forms a length of 1 meter (drill bit can be selected:Φ35 TheΦ40Φ45 TheΦ50，Length 350mm400mm）
2. Drill rod length:Φ25mm*1m
3. The base of the lifter and the lifter clamp can be matched to pull out drill rods and drill bits.

If the lifter clamp and lifter base are not included, please specify when purchasing；The number of small drill rods and drill bits can be adjusted according to customer requirements for configuration.

Note: Supporting facilities10kgHammer, touch probe, hammer pad, can be used forCollection of foundation bearing capacity parameters. Using a certain amount of hammer energy to impact the foundation soil
Make an engineering geological evaluation. By adding a micro soil sampler, shallow drilling can be carried out, and small samples in the form of columns and shapes can be taken for general physical and mechanical tests.
Take undisturbed soil samples with partial flow plastic, soft plastic, plastic, silt, and sand quality, as well as flow plastic and soft plastic quality.
