1. Retrofitting a 25-meter-height extension mast that is detachable.
1) When conducting jet grouting pile within 29.5-meter-depth, rely on the extension mast, no need to connect and disconnect the drilling pipes over and over again, which reduces time, material and potential quality problems. If conducting more than 29.5-meter-depth pile, user can keep connecting drill pipes and continue the drilling-in and grouting job.
2) The extension mast is with standard design, with 5 sections that can be freely combined to 10m, 15m, 20m and29m.
2. Hollow rotary head
1) With 92mm diameter, which guarantees clear pass for dia89mm drilling rod.
2) With hydraulic chuck structure, which makes changing drilling tools much more convenient and easier, no need to worry about connecting types of transition joint.
3) With large torque rotary head, combined with our intensive drilling tools, it can drill through directly without making any guiding holes, which can save a lot of time.
3. We provide drilling data device for alternative, it can achieve real-time recording of grouting pressure, grouting flow, lifting speed, rotary speed and other construction parameters.
