RJP jet grouting method

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 a fan-shaped column.

RJP method has the particularity at the construction site and construction conditions etc. RJP method is a kind of excellent construction and very economical construction mode.

RJP method is quite suitable for megaproject, complex foundation project. RJP method uses triple tubes or four tubes and transport water, air and liquid respectively. And cement liquid is adopts super high pressure (35-40Mpa) spraying. And the air that around will secondary impact cut soil. And this can cause a large diameter modified body.

LGP500/700/100PI-E grout station is a combination of mixer, agitator and grout pump in one plant. It is mainly used in highway, railway, hydropower, construction, mining and other ground and underground construction. High speed vortex mixer ensures mix quickly and evenly. Water, cement and other media are quickly mixed into a homogeneous slurry. Then the mixed slurry was delivered to the agitator. Grout pump injects from the mixing drum (storage tank). This ensures a continuous mixing and grouting operations. The grouting pump is hydraulic drive. Grouting pressure and displacement is stepless adjustable. Compact size and it is easy to operate. It also takes up a small space. Description Data Grout Station model LGP500/700/100PI-E Dimensions 2700*1750*1650mm Weight 1440kg Mixer Capacity 500L Output 7m3/h Power 7.5Kw, 1450rpm,50Hz,380V
