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

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 common construction machinery equipment, rotary drilling rig is widely used in construction, infrastructure construction and other fields. The operation of rotary drilling rig not only needs to master the basic mechanical operation skills, but also needs to have certain theoretical knowledge an 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
