Reverse Circulation RC Drilling Rig Machine Exploration 300m Depth Hydraulic Core Drilling Rig
Machine Introduction
RC drilling is a quick and efficient method that has the potential to cut overall drilling cost significantly, while maintaining good sampling quality. When carried out correctly, RC drilling will reduce dramatically both overall drilling costs and impact on the environment.
This RC drilling rig is able to resolve the difficulty of boring in the soft and loose cover ground condition, the screes and gravels area and also the fragmentation stratum according to different drilling techniques ways. Therefore, it is widely used in varieties of the boring work.
The Reverse circulation (RC ) drilling rig is mainly applied in RC drill/water well and observation well, geothermal hole,mini foundation pile hole.
Application
RCJ300RC hydraulic RC drilling rig is mounted on a crawler chassis,driven by full hydraulic system, power head type drilling rig, which is used to drill vertical or inclined hole, and also the drilling techniques way of the following:
Drill auger drill
Down-The-Hole hammer drill
Mud forward circle drill
ODEX tools(casing pipe following) drill with DTH hammer
Medium reverse circle drill
Wireline core drilling after change core drilling rotary unit head

Machine Advantages
With its efficient fully hydraulic drive system, design that does not require an active drill pipe, and large feed stroke, the RC drilling rig significantly improves drilling efficiency and reduces auxiliary time. Its powerful thrust and lifting force ensure effective drilling and have the ability to handle unexpected situations. The equipment of the tie rod device meets the needs of twisting the drill pipe and reduces the labor intensity at the same time. The design of the crawler chassis makes the movement of the RC drilling rig very convenient. Key hydraulic components are selected from the world ' s high - end technology products or well - known brands, and are equipped with a monitoring system to ensure system reliability and low failure rate. The RC hydraulic drilling rig supports a variety of drilling methods, such as non - circulating liquid dry auger drilling, rock formation DTH hammer drilling, sandy soil layer mud circulation drilling, etc., and is suitable for drilling operations in various geological conditions.
