Bored pile construction in large inclination and complex geological conditions poses significant challenges. Due to the steep strata inclination and possible uneven soil characteristics, risks such as sliding, collapsing, and deviations often arise. Scientific construction techniques and methods are 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

Rotary drilling rigs play a crucial role in modern foundation engineering, and their rock penetration ability directly determines construction efficiency and pile quality under complex geological conditions. The key to rock penetration lies not only in the overall performance of the equipment but al 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

Using a rotary drilling rig to operate in soft soils, silt, fine sand, or other collapse-prone layers is a challenging task. The low strength, poor drainage, and high compressibility of these layers make issues like hole collapse and drill jamming common, affecting construction efficiency and pile f Read More
