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

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

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

Granite soil layers are challenging for foundation engineering due to their high hardness, dense structure, and strong compressive strength. Rotary drilling rigs working under these complex geological conditions require not only high-performance tools and equipment but also scientific operational me Read More

Mechanism of Vibratory Pile Sinking Vibratory pile sinking is the construction method of using vibratory hammer for pile sinking. Setting up the vibrating hammer driven by electricity, gas, water or hydraulic pressure, the eccentric hammers in the vibrating hammer rotate against each other, the lat Read More
