GK-200 Crawler Mounted Drilling Rig Features:
Crawler drilling rig is composed of crawler chassis, diesel engine, drilling rig, landing gear and water pump, which are jointly assembled on one frame. The drilling rig, water pump and crawler chassis are driven by the same power (diesel engine or motor), and the power is transmitted to the drilling rig, water pump and crawler chassis respectively through the transfer case. The machine has the advantages of strong climbing ability, stable and reliable drilling and walking, large load quality and so on. It is suitable for the engineering geological survey of urban construction, line, water conservancy, electric power, bridge, dam foundation and other buildings, as well as the drilling of small grouting holes, water wells, dewatering holes and blasting holes.
Geophysical exploration
It is abbreviated as geophysical exploration. It is to detect geological conditions such as formation lithology and geological structure by studying and observing the changes of various geophysical fields. The commonly used geophysical exploration methods include DC exploration, AC exploration, gravity exploration, magnetic exploration, seismic exploration, acoustic exploration and radioactive exploration
