A mixing plant is a facility that combines raw materials like aggregates (sand, gravel), cement/bitumen, and water to produce construction materials such as concrete or asphalt for road building and other projects, with types ranging from large stationary setups for massive projects to mobile units for temporary or remote sites, focused on efficiency, quality, and precise material ratios.
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.
Unsere Fundamentbohrwerkzeuge sind die härtesten, stärksten und haltbarsten in der Bauindustrie, die speziell für das Bohren von tiefen Löchern bei Bauprojekten entwickelt wurden. Unsere Schneidwerkzeuge sind für ihre außergewöhnliche Haltbarkeit und Verschleißfestigkeit bekannt und werden häufig beim Bau von Fundamenten großer Strukturen wie Gebäuden, Brücken und Türmen eingesetzt.

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.
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.
