Application of Rotary Drilling Rigs in Pile Foundation Construction
With economic development, an increasing number of advanced machines have been introduced into China, and the rotary drilling rig is one of the drilling machines introduced in recent years. Since its introduction into China, the rotary drilling rig has been highly praised by construction professionals for its fast drilling speed and high drilling quality, and has thereby become the primary method in pile foundation construction today. To date, rotary drilling rigs have been widely used in pile foundation construction for infrastructure such as highway and bridge construction. They can drill boreholes of the required depth and diameter under various geological conditions, and are very convenient to operate, greatly improving construction efficiency, shortening project duration, and reducing construction costs.
