Geotechnical 300mm 200m Soil Testing Drilling Rig
Cheap 200m Soil Test Drilling Rig Machine Available for Geotechnical Exploration
Brief Introduction
Available Geotechnical Exploration 200m Soil Test Drilling Rig Machine
ST-200 type engineering drilling rig is a new generation of portable multi-purpose engineering survey and construction rig, which aims at optimizing the design of most of the same type drilling rigs in the domestic market. It is suitable for industrial and civil buildings, railways, bridges, etc. The engineering geological exploration of hydropower and other departments, as well as the construction of small diameter pile holes, have the following characteristics:

Product Feature:
1. The speed range is wide, the gear is reasonable.
2. Low speed, large torque, can be used for drilling machine sampling and pile hole construction.
3. Equipped with front-and-back moving cylinder, so the whole rig can move freely 300 mm, which brings a lot of convenience to the drill.
4. Hydraulic feeding, easy to operate, high drilling efficiency and low labor intensity.
5. The chuck of drilling machine adopts hydraulic roller type, easy operation, reliable clamping and no damage to active drill pipe.
6. Compact structure, small size, light weight.
7. Adopt 9 spring reinforced large torque clutch, reliable clutch, larger torque transfer, strong impact resistance and long life.
8. Increase input shaft spline specifications, torsion resistance significantly improved, longer life.
The specific steps of 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
