The KR250ES Low Headroom Hydraulic Piling Rig is a high-performance foundation drilling machine specially designed for projects with height restrictions. Combining robust torque capacity with a compact structure, it is ideal for construction work in urban environments, under bridges, or inside industrial buildings. Engineered by top industry standards, the KR250ES delivers reliable, efficient, and precise piling solutions where traditional rigs cannot operate.
TZJK-TD series of special ceramic slury pump is developed by on the basis of TZJ series slurry pump.combined with the latest ceramic technology,the flow parts are ceramic slury pump products.The service life can reach 3-10 times the metal fow parts and obtain the national invention patent Up to now,special ceramic slury pump can meet all pump stations in the mineral processing industry,including "one-stage grinding pump"and "high-pressure roller grinding process pump",which has created a new era of wear-re-sistant performance in the slurry pump industry,saving nearly half of maintenance costs and labor costs for customers,and promoting the development of China's "fourth generation slurry pump".

Spherical hobs are very mature and are widely used in many equipment, such as rotary drilling rigs, RCD, pipe jacking machines, etc. By analyzing the use of ball-tooth hobs on the above equipment, it can be known that when there is sufficient propulsion pressure and the rock layer strength is about 130MPa, the footage speed of the spherical tooth hob can be maintained at 0.3~0.5m/ h. And the footage speed is relatively stable. When the spoil discharge is sufficient, the service life of one spherical tooth hob can reach a construction length of 300m.
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.
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.
