Tato sada žacích kol je vhodná pro širokou škálu půdních podmínek a účinně zabraňuje ucpávání v jílovitých vrstvách. Navíc prodlužuje životnost kol při práci v tvrdých horninových formacích.
It is made of high quality steel GB-Q345B with special soil teeth which can avoid inclined hole. This tool is applicable to different layers such as clay, high-weathered layer, gravel, etc. It is a reliable and efficient drill tool for drilling deep hole and wide range of applications.
This precision-engineered gearing box is specially designed for trench cutters (hydromills), delivering high torque transmission, durability, and structural stability under extreme working conditions. It ensures reliable power output for vertical trenching in diaphragm wall construction and soil mixing applications.
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.
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.
Hydraulic Vibro Hammer is a construction tool using hydraulic power to generate high-frequency vibrations, vibrating piles (like sheet piles, pipes, H-beams) into the ground by temporarily liquefying soil, making installation faster and quieter than impact hammers, and is used for foundation work, retaining walls, and marine projects.
