Rotary drilling rigs, as heavy machinery, endure significant loads and complex working environments during construction. In certain cases, these rigs may overturn, which not only causes equipment damage but also poses a serious safety risk to operators. Therefore, understanding the causes of rotary Read More

Pile foundations are a crucial part of structural engineering, transmitting loads from the superstructure to the underlying soil. Based on their load transfer mechanism, pile foundations are classified into end-bearing piles and friction piles. These two types differ significantly in terms of load-b Read More

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

Rotary drilling rigs are widely used in construction engineering, especially in rock drilling operations where their efficiency and flexibility are fully demonstrated. However, rock drilling imposes higher demands on equipment and techniques. To ensure efficiency and quality, certain basic condition 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
