Grouting equipment

  In general terms, grouting is that fluid material went into fractures and cavities in rock, soil or artificial structures under pressure. Depending on the composition and mix of the injected material, it will react physically and chemically. Stabilise, strengthen or seal the ground or the structure. This is the purpose of grouting. There are mainly for types of grouting method: Compaction grouting (Displacement), cement grouting (Intrusion), Chemical grouting (Permeation), jet grouting (Replacement). Usually, four major application areas are grouting use: grouting for dams and canals, sub-surface grouting, grouting for foundations, grouting in connection with constructions.   As the above picture shows, four grouting methods are different. And all are widely used in different grouting projects. Compaction grouting is accomplished by forcing extremely stiff cement mortar like grout into the sub-grade soil under high pressure to form a uniformly consolidated mass to displ

RJP method also named RODIN JET PILE method. It is by using kinetic energy that ultra-high pressure spray fluid produced to damage to the foundation of the organization. Then mixing these damaged soil particles and hardened materials. This can result in large diameter modified body. Ultra-high pressure water and air spray fluid doing the guide cutting in the upper section. This can create a certain space. Lower section ultra-high pressure hardening material and air spray fluid can expand the cutting energy. Compare to the original method that occlusion space cutting, RJP method is more effective in cutting and destroying soil effects. In addition, since the energy at the time of cutting is increased, the mud can be smoothly discharged. The RJP method installs the ultrahigh pressure jet nozzle and the cement slurry jet nozzle in the same direction. It is designed to the back and forth injection angle. As the injection angle is 90º to 270º, the modified body can be sprayed into
