Hard clay and mudstone layers are characterized by high strength and compactness, making drilling significantly more challenging compared to softer soil layers. These formations require stricter demands on the selection of drill bits, operational parameters, and drilling techniques. Improper handlin Read More

Boulder and cobble layers present a challenging geological condition characterized by high hardness, uneven distribution, and a mixture of soft soil or other strata. Such conditions impose strict requirements on equipment and techniques. Without proper handling, issues like drill bit damage, reduced Read More

1. PreambleIn the construction of bridges in hard geological areas, the commonly used pile foundation construction methods are hand-dug pile method and percussion drilling method. Manual drilling method is gradually eliminated due to the long pile construction period, backward technology, and the ne Read More

Only by making preparations for the transportation, assembly and disassembly of the rotary drilling rig and the positioning of the machine can we improve the drilling speed and prevent hidden dangers.What are the points of safe transportation?1.orientationBefore the upper board car, first understand Read More

The power head is the core component of a rotary drilling rig, responsible for providing rotational and lifting force to ensure efficient operation of drill rods and drill bits under various geological conditions. However, during construction, the power head may experience insufficient torque issues Read More
