A core barrel is a type of drilling Tools used to cut through extremely hard surfaces such as pile foundation Underground Rock and Concrete. This equipment is typically utilized by industrial construction companies and geological survey teams. The core barrel can be roughly divided into three categories according to different functions and geological conditions, cross cutter core barrel, roller bit core barrel, core barrel with teeth.
Cross cutter core barrel drilling is a circular piece of machinery with an open center portion that can be used to extract the rock pillars in the pile foundation, lock the rock core with the unique internal structure, break the rock pillar through the torque of the rotary drilling rig, lock the broken rock core and extract it to the specified area on the ground for storage, which is convenient for rock engineers to analyze the geology Situation and calculation of engineering quantities.
The core barrel with teeth is the most common one. It can cope with most strata with a hardness lower than 80MP. It can be used for a long time only by frequent maintenance and replacement of the teeth and the external slag-removing iron bars. Depending on the size of the pile diameter The core barrel of different heights can be customized. Under the premise of ensuring the maximum lifting height of the drill pipe of the rotary excavator, the higher the core barrel height is, the easier it is to twist and extract the core, and the more construction time is saved.
The roller bit core barrel is a sharp tool to solve the hardness of granite above 80MP. It slowly grinds and cuts the rock through the bits of nickel-chromium alloy, thereby deepening the depth of the pile foundation, reaching the standard depth required by the engineering design, and advancing the construction progress. In the case of this hard rock formation, the construction progress can reach up to 50mm/h, because the stone is too hard.
Core barrels are a valuable tool for drilling contractors and operators. They are used to drill the borehole and remove the core. A number of benefits can be achieved through the use of a core barrel. Some of these benefits include:
1. Reduced drilling time - A core barrel can drill a borehole faster than other drilling tools. This is because the barrel is designed to remove the core from the borehole as it is drilled, allowing the drill bit to continue cutting.
2. Increased accuracy - A core barrel is more accurate than other drilling tools. This is because the barrel is designed to remove the core from the borehole in a straight line, ensuring that the borehole is drilled in a straight line.
3. Improved pile hole quality - The use of a core barrel can improve the quality of the pile hole. This is because the barrel is designed to remove the core from the borehole without causing damage to the formation. This can help to avoid formation damage and improve pile hole stability.
Core barrel are the perfect tool for drilling holes in the ground. With a variety of sizes and options available, there is a core barrel for every job. They are durable and easy to use, making them the perfect choice for any drilling project.
If you are looking for a reliable and durable tool for drilling holes in the ground, then a core barrel rock auger is the perfect choice.
