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

The pressurizing device is a critical component of rotary drilling rigs, primarily responsible for applying vertical downward pressure to the drill rods and drill bit, enhancing drilling efficiency and performance. By combining hydraulic systems with mechanical transmissions, the pressurizing device Read More

In highway bridge construction, pile foundation construction is a critical step to ensure the stability and safety of the bridge. The primary function of the pile foundation is to transfer the load from the superstructure of the bridge to the deep soil or rock layers, providing reliable support and Read More
