1. Check the appearance of wear: If the drill shell, drill pipe and other parts have a large number of scratches and deformation, it indicates that it is used frequently, which may affect the subsequent life.2. Check working hours: the number of working hours is large, the components run for a long 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

1. High construction efficiencyThe drilling speed of rotary drilling rig is 15-20 times higher than that of traditional percussion drilling, and it takes only 3-5 hours for a single hole operation, and the mechanised operation reduces the reliance on manual labour, which significantly shortens the c Read More

As a large mechanical equipment, rotary drilling rig is widely used in geological exploration and infrastructure construction. Due to its complex working environment and large equipment volume, special attention must be paid to safety when operating rotary drilling RIGS. The following are the safety Read More

Rotary drilling rig is widely used in many fields such as foundation, bridge construction and tunnel construction. According to different construction needs, rotary drilling RIGS can be divided into small, medium and large, each of which has its own advantages and is suitable for different environme Read More
