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

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

Rotary drilling rigs are advanced construction equipment widely used in foundation engineering projects such as bridges, buildings, and docks. Their efficiency and ability to adapt to complex geological conditions make them essential for deep foundation construction. However, to ensure smooth operat Read More

Desert environments pose unique challenges for rotary drilling rig operations due to high temperatures, dryness, strong winds, and specific geological conditions. These factors can affect construction efficiency and pose risks to equipment and personnel. Therefore, scientific measures must be adopte Read More

The power head is one of the core components of a rotary drilling rig, directly determining the rig’s performance and construction efficiency. As a critical device providing torque and driving force, the power head’s functionality impacts drilling speed, borehole quality, and overall equipment stabi Read More
