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

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

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

Hard clay and mudstone layers are characterized by high strength and compactness, making drilling significantly more challenging compared to softer soil layers. These formations require stricter demands on the selection of drill bits, operational parameters, and drilling techniques. Improper handlin Read More
