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

------------------------- 1 ------------------------- Wire rope uncoiling as well as installation, the correct method should be used to prevent wire rope kinking. Also pay attention not to make the surface of the wire rope stained with sand, so as not to exacerbate the wear and tear, affecting the s 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
