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

------------------------- 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

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

Boulder and cobble layers present a challenging geological condition characterized by high hardness, uneven distribution, and a mixture of soft soil or other strata. Such conditions impose strict requirements on equipment and techniques. Without proper handling, issues like drill bit damage, reduced Read More

1. PreambleIn the construction of bridges in hard geological areas, the commonly used pile foundation construction methods are hand-dug pile method and percussion drilling method. Manual drilling method is gradually eliminated due to the long pile construction period, backward technology, and the ne Read More
