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.
The HM-14 full-hydraulic multifunctional ground improvement equipment is designed for small-section tunnels and coal mine roadways.
Le Vibroflot fonctionne selon le principe du compactage par vibration. Son vibrateur puissant génère des vibrations à haute fréquence qui sont transmises aux particules du sol. Sous l'influence de ces vibrations, les particules de sol libres se réorganisent, réduisant les vides et améliorant de manière significative la densité et la portance du sol. En outre, le système de rinçage à l'eau intégré contribue à ameublir le sol pendant le fonctionnement, ce qui permet au vibrateur de pénétrer plus profondément dans les couches du sol et d'optimiser encore les résultats du traitement. Qu'il s'agisse d'un sol sableux, d'un sol limoneux ou d'autres sols liquéfiables, le Vibroflot renforce efficacement le sol, empêchant ainsi le tassement des fondations et fournissant une base solide et stable pour les superstructures.
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.
