Rotary drilling is an advanced construction method widely applied in fields such as bridges, building foundations, and ground improvement. It relies on rotary drilling rigs, which use drill bits to cut through soil or rock and discharge it out of the borehole to create pile holes. The quality and ef Read More

During the operation of rotary drilling rigs, vibration is unavoidable, especially in hard rock layers or complex geological conditions. Excessive vibration can not only damage key components of the equipment but also lead to safety accidents, affecting construction progress and costs. Therefore, mi Read More

Rotary drilling rigs are widely used in foundation construction due to their efficiency and flexibility. In rock drilling operations, their performance directly affects construction efficiency and project quality. The rock drilling capability of rotary drilling rigs mainly depends on the pressure mo Read More

The drill bit is one of the most critical components in rotary drilling rigs during rock penetration operations. Its performance directly determines the efficiency of breaking through rock layers and overall construction productivity. As the tool that directly contacts the rock formation, the drill Read More

When constructing in hard rock strata, rotary drilling rigs must overcome the high hardness and compressive strength of rocks. Unlike drilling in soft soil layers, rock penetration primarily relies on specialized drilling tools and impact methods to break the rock and achieve efficient construction. Read More
