The overburden casing system by Changsha Tianhe is a cutting-edge technique used in various drilling operations such as water well drilling, anchoring, micro piling, and geothermal engineering. It involves the installation of a casing or pipe through overlying layers of soil, rock, or other materials to provide unparalleled support and stability during the drilling process.
