The single roler bit is composed of a single cone and a lug matched by a bearing.According to different strata and construction requirements, different cutting struclures can be selected; wear resistant carbide are welded and cemented carbide inserts are inserted on the back of the lug.
Rotary drilling rig drives the shaft to rotate and exert positive pressure so that the rotary dril- ing bit can impact, roll and shear the rock. Crush the rock to form a crushing ring zone.Then break the middle pillar by the swing of the shaft and take the broken pillar out to form a hole.
The MJS Method (Metro Jet System) utilizes a specially designed porous pipe and front-end device to achieve stratum cutting via high-pressure jet flow and inject hardening materials. Combined with an active sludge discharge system and real-time underground pressure monitoring technology, it precisely regulates construction pressure to ensure stable pile-forming quality, while significantly reducing disturbance to the surrounding environment. It is suitable for multi-angle and large-depth foundation reinforcement projects.
KR360C/M Caterpillar Chassis Built With A Series Of Full Electric Control Rotary Drilling Rig
HPR35 Mini rotary drilling rig offers low clearance and lightweight construction as its core advantages, making it ideal for confined working environments and complex site access requirements.
Mainly used for ground improvement works and anchor drilling, the line includes a remarkable variety of models that, depending on the excavator size, can reach up to 15 tonnes pull-up force. The drilling attachments of the line can be equipped with a wide range of rotary heads drilling systems. All set-up and drilling movements can be controlled by the operator directly from the excavator cabin, remote control, with great advantages in terms of efficiency, productivity and safety.
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.
