Rotary drilling rigs are widely used in foundation construction, and their pressurization method significantly impacts their performance and construction efficiency. Hydraulic cylinder pressure and wire rope pressure are two common pressurization modes, each with distinct characteristics in terms of Read More

The clear water construction process is a widely used method in specific geological conditions for rotary drilling rigs. By using clear water as the circulating medium, this method ensures borehole cleanliness and stability while maintaining high construction quality. It is commonly employed in soft Read More
