Rotary drilling rig plays an important role in modern engineering construction. The skill level of the operator directly affects the progress and quality of the project. Let's take a look at what skills operators need to focus on.1. Equipment operation skills: master the starting and stopping proces Read More

In the process of urban construction, the construction site is often narrow and cramped, which challenges the spatial adaptability of construction equipment. As a common drilling equipment, rotary drilling rig has attracted much attention for its ability to operate in a narrow space. So, can the rot Read More

In the construction, the rotary drilling rig undertakes the vital drilling task, and its performance is directly related to the progress and quality of the project. It is the key components that determine the performance of rotary drilling RIGS. How to accurately purchase these key components is a s Read More

1. Mud wall protection against hole collapseWhen drilling the loose soil layer is easy to collapse by the horizontal soil pressure, the mud balances the soil pressure by the outward pressure, forming a stable ‘mud skin’ to protect the hole wall.2.Characteristics of non-circulating mud processThe rot Read More
