In highway bridge construction, pile foundation construction is a critical step to ensure the stability and safety of the bridge. The primary function of the pile foundation is to transfer the load from the superstructure of the bridge to the deep soil or rock layers, providing reliable support and 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

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
