The RJP-3.0 Method realizes real-time monitoring and regulation of construction parameters through the jet drilling real-time measurement system, addressing the drawback of lacking key parameters in traditional jet grouting technology. It can simultaneously acquire basic parameters such as nozzle holder lifting speed, rotation speed, nozzle diameter and quantity, air pressure, slurry flow rate, and pump outlet pressure. It achieves real-time drilling deviation monitoring and dynamic collection of downhole pressure inside and outside the drill pipe, assists in analyzing the actual kinetic energy of the slurry and inferring the pile diameter, and forms a closed-loop control system by integrating post-construction deviation data. This significantly improves the preparation accuracy of the soil-cement mixture and construction reliability.
Kelly Bar Spring is a precision-engineered elastic component used in rotary drilling rigs to absorb impact and reduce vibration during drilling operations. It plays a vital role in protecting the Kelly bar sections and rotary drive system, ensuring smooth, safe, and efficient pile construction.
The DTH hammer supporting the rotary drilling rig can make the rotary driling rig give full play to its equipment advantages, ensure that customers can successfuly complete all kinds of work in the rock, achieve multi-purpose one machine, end make full use of existing equipment. Reduce the investment cost of customer equipment and form urique competiveness.

Posicionada na parte superior da coluna de perfuração, a Kelly Bar serve principalmente para transmitir o binário e suportar o peso total da coluna de perfuração. É um componente essencial para garantir o funcionamento estável e a penetração precisa do equipamento de perfuração em vários domínios, incluindo a perfuração de petróleo, a perfuração de fundações de construção e a exploração mineira. A sua transmissão de binário eficiente permite que a broca atravesse várias formações de solo e rocha, garantindo a progressão suave das operações de perfuração.
