Casing pipes are critical structural components in anchor drilling operations, serving as temporary or permanent protective casings that stabilize boreholes during the installation of ground anchors and other deep foundation elements. In geotechnical engineering applications, casing pipes maintain borehole integrity by preventing soil collapse, particularly in unstable, loose, or saturated ground conditions where drilling without support would result in significant ground loss and foundation failure. These cylindrical steel tubes are advanced into the ground ahead of drilling operations, creating a stable environment for anchor installation, grouting, and load transfer to competent soil strata or rock formations. The selection and installation of appropriate casing pipes depend on soil classification, groundwater conditions, drilling depth, and the required load-bearing capacity of the anchor system. In cohesionless soils such as sands and gravels, casing provides essential borehole wall support against hydrostatic and lateral earth pressures, while in cohesive soils or rock, lighter casing may suffice or be eliminated entirely. Casing pipe diameters typically range from 76 to 1,016 millimeters, with wall thickness and material properties selected based on engineering calculations and geotechnical investigation data. The casing is often rotated and advanced using specialized drilling rigs equipped with casing cutters, with extracted material managed through circulation systems that facilitate grouting operations and pore pressure monitoring during installation. Applications of casing pipes in deep foundation work include permanent or temporary support for ground anchors in tied-back excavations, slope stabilization projects, basement construction adjacent to existing structures, and infrastructure foundations requiring lateral support systems. In major construction projects, casing pipes enable the installation of high-capacity anchors that distribute loads across deeper, competent strata, reducing settlement and providing structural stability for temporary and permanent works. The integration of casing pipes with injection grouting systems allows for controlled pore pressure management, improved load transfer through anchor bonds, and enhanced durability through corrosion protection. Professional contractors and geotechnical engineers utilize casing pipe technology to enable safe, controlled drilling in challenging subsurface conditions, thereby reducing construction risk, accelerating project timelines, and ensuring compliance with building codes and stability requirements for foundation systems across residential, commercial, industrial, and infrastructure sectors.
