ST 50 Geological Drilling Rig 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.
7. It has strong decomposition ability and is easy to move. It is suitable for working in hilly, mountainous and other complex terrain.
ST 50 Geological Drilling Rig Exploration Ways:
Drilling refers to an exploration method in which a drilling rig is used to drill holes in the stratum to identify and divide the stratum under the surface, and samples can be taken along the hole depth. Drilling is the most widely used exploration method in engineering geological survey. It can obtain deep geological data.
ST 50 Geological Drilling Rig soil sampling method are as follows:
1. Distribution: samples shall be taken according to the soil type and the distribution of crop varieties, and according to the different soil fertility. The sampling points are distributed in zigzag or snake shape, which should be as uniform and random as possible.
2. Determine the sampling position and depth: the sampling position and depth shall be determined according to the thickness of the cultivated layer. Generally, the sampling depth is 0-20cm
