Geological Drilling Rig Prospecting 300mm Diameter GK 200 Hydraulic Borewell Machine
GK 200 Geological Drilling Rig Introduction:
GK-200 Drilling Rig is a light multifunctional engineering project prospecting drilling rig
With the hydraulic feeding mechanism,improve the drilling efficiency,reducing the labor intensity of workers.
The rig is equipped with a ball on a cassette holding mechanism and a six side rod, the rod can be replaced without shutdown, high work efficiency, safe and reliableFurnished with hole bottom pressure gauge pressure indicator,and easy to master the status inside the hole
The handle centered, convenient operation.

3. For 40’ container, the max loading weight is 27 metric tons.
4. Usual loading port is XINGANG port in Tianjin, main port in north of China.
Drilling Rig Applications
It is a survey method to find out the underground geological conditions. It can be divided into: (1) geophysical exploration: lithology, groundwater level, karst cave distribution, etc. are divided according to the conductivity, magnetism, density and the propagation speed of elastic wave in different underground strata and media (water, cavity, rock, etc.). Guide drilling. (2) Drilling: combined with pit (groove) exploration. 3) penetration: it is both an exploration method and an in-situ test method.
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
