Rotary Drilling Rigs in Sandy and Loose Soil Conditions

Special geological conditions, such as sandy or loose soil, present unique challenges in pile foundation construction. Rotary drilling rigs like the XCMG Used Rotary Drilling Rig and SANY Used Rotary Drilling Rig are equipped with advanced features to address these difficulties. This article explores how these rigs excel in such environments.

Challenges of Sandy and Loose Soil

Borehole Collapse
Loose soil is prone to instability, causing boreholes to collapse during drilling.
Water Seepage
Sandy soil often has high permeability, leading to water ingress that complicates operations.
Reduced Friction
Low friction in loose soil can affect the stability of piles and drilling equipment.
