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. Filled piles: rotary drilling rig drills holes, puts in reinforcement cages and then fills them with concrete, which carries the upper load of the building after hardening.2. Prefabricated piles: prefabricated in factories or on site in advance, sunk into the ground with the assistance of rotary 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

The rotary drilling rig is an efficient piece of equipment widely used in foundation construction, deep pit excavation, and other projects.
