used for dam reinforcement and foundation pile construction to improve the stability of dams.
Reservoirs and ports
In the infrastructure construction of reservoirs and ports, rotary drilling rigs are used to drill pile foundations to ensure the stability of the structure.
Rotary drilling rigs are often used in pile foundation construction of high-rise buildings, and can complete large-diameter, deep foundation pile holes in a relatively short time.
Underground buildings
In underground construction projects such as underground parking lots and subway stations, rotary drilling rigs can drill holes efficiently to meet complex underground construction needs.
