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

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

Secant piles are a specialized construction technique widely used in deep foundation pit support and diaphragm wall construction. By interlocking individual piles, they form a continuous pile wall, achieving water stoppage, seepage prevention, and load-bearing purposes. The construction of secant pi 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
