ST 50 Geological Drilling Rig Main Features:
1. Double oil cylinder hydraulic feeding system, the drilling speed is fast and the working efficiency is high.
2. A fixed clamping mechanism and an integrated main rod, which does not need a drilling tower and works conveniently.
3. 4-speed transmission system. The operator can freely adjust the forward rotation speed through three gears, and is also equipped with a slow reverse gear, which is convenient for the operator to disassemble the drill pipe and drill tool.
4. The handle is centralized, easy to operate, safe and feasible.
5.A pressure gauge at the bottom of the hole to indicate the pressure, which is convenient to master the situation in the hole.
6. Compact structure and small floor area.
What is a soil sample investigation?
Soil investigation is to carry out physical testing on-site to understand the ground conditions for geotechnical design. Site works usually consist of the Cone Penetration Test, Vane Shear Test, Standard Penetration Test, Installation of Water Standpipe, Instrumentation's, etc.
