China Deep Foundation Engineering Network NewsRecently, we learned from Changzhou Hongye Foundation Engineering Co., Ltd. (hereinafter referred to as "Hongye Foundation") that, upholding the spirit of unremitting efforts for local economic development and continuous innovation to improve China's professional construction technology level, Hongye Foundation has achieved successive successes in this era full of challenges and opportunities. It has been granted two patents: "A Rotary Drilling Rig Power Head with a Mobile Structure and Its Drilling Method" and "A Needle-Tube Extrusion Drill Bit with Slag Discharge Function for Rotary Drilling Rigs," further enhancing the performance of rotary drilling rigs!

The first is their designed rotary drilling rig power head with a mobile structure and its drilling method. This innovative equipment adopts a structure composed of a support frame, a driving device, and multiple drill pipes. Through the precise design of a displacement mechanism, a press-fitting mechanism, and a rotation mechanism, the connection between drill pipes is made easier and operation simpler. Moreover, it ensures stable power transmission between drill pipes and avoids drill pipe damage caused by inaccurate meshing positions of the pressure-applying platforms. In addition, the drill pipes of this power head are not multi-layer telescopic, making maintenance very convenient and increasing the service life of the drill pipes. More importantly, the drilling depth is limited only by the number of drill pipes and is no longer subject to other restrictions, bringing us greater construction space!

Next, let us learn about the needle-tube extrusion drill bit with slag discharge function for rotary drilling rigs. This drill bit adopts an innovative design, including a drill barrel and a cutting disc located at the top of the drill barrel. Inside the drill barrel, a driving mechanism, an extrusion disc, and a cleaning mechanism are arranged. The driving mechanism drives the extrusion disc to slide along the axis of the drill bit while carrying soil, and at the same time it can also rotate, thoroughly solving the problem of poor soil discharge. At the same time, the extrusion disc also drives the connected cleaning mechanism to move, achieving thorough cleaning of the inner wall of the drill barrel and greatly improving work efficiency. This not only reduces the burden on workers but also ensures the cleanliness inside the borehole, making subsequent rotary drilling operations smoother and faster!

With the acquisition of these two patents, Changzhou Hongye Foundation Engineering Co., Ltd. has once again demonstrated its leading position in technological innovation. This not only brings the company unlimited business opportunities but also injects new vitality into the domestic rotary drilling rig industry. It is believed that in the future their efforts and innovative spirit will continue to drive the company's development and enable their technology to be more widely applied in the deep foundation field.
