SPT Sample Collection New Condition Diesel Soil Investigation Machine
Soil Investigation Machine Description:
Used for general investigation, geophysical exploration, high-way and building construction, and blast-hole drilling etc.
With hydro-automatic feeding device, and high drilling efficiency.
Designed with hydro-chucking unit instead of slips to ensure drilling from stop when changing pipes.
Close levers, convenient to operate, safe and reliable operations.
Compact in structure. All the drill, water pump and diesel engine installed on one base frame result in space-saving.
Light in weight, easy disassembling for transportation and applicable to working conditions in plain and mountain areas

Selection Principle Of Crawler Soil Investigation Machine
(1) Applicable in production
In order to meet the needs of engineering construction, the selected drilling rig should be reasonably allocated according to the construction tasks undertaken by the enterprise under normal conditions, and the application of the drilling rig should be fully considered. It should not only meet the current construction needs, but also take into account the demand for drilling rigs under other production conditions in the future. Only the drilling rig with strong applicability in production can better show its investment effect.
(2) Advanced in technology
While meeting the production needs, it is required to maintain the advanced performance of its performance indicators, which is conducive to extending its technical life and will be eliminated in a short time. In the long run, it will meet the requirements of sustainable development of enterprises and protect investment effectively.
(3) Operability and maintainability
The operation is simple, which is convenient for workers to master the operation skills and shorten the auxiliary operation time, such as field leveling, drilling rig displacement, lifting and lowering of drill frame, drill pipe connection and replacement, adjustment of gas and water valve, etc.
(4) Safety and environmental performance
At present, our country attaches great importance to the safety and environmental protection performance of products. When purchasing new equipment, we should pay attention to whether the manufacturing materials, various safety devices are complete, whether the construction noise, waste gas and waste discharge meet the requirements of relevant laws and regulations.
(5) Economic rationality
It is required that the purchase price of crawler DTH drilling rig is reasonable, the energy consumption and maintenance cost are low in the use process, and the investment payback period is short, so as to facilitate the enterprise capital flow.
