Grout pump and mixer, also known as compact grout plant , it is suitable for all grouting applications with cement and ultra fine cement. Compact grout station is also suitable for bentonite suspensions for microtunnelling, pipe jacking and directional drilling. LGP800/1200/200PI D grout plant is a double cylinder grout pump and mixer . 800L mixer and 1200L agitator are both made by using stainless steel. Mixer and agitator switch by using squeeze handle, it is safe, reliable and easy to operate. Special squeeze hose (resistant to more than 50000 times extrusion), no valve switch device.     Water and solid materials are drawn through the high-speed mixer tank. It rotating at speeds of up to 1,500 RPM to prevent flocculation and achieve complete particle wetness. Mixing time is significantly reduced by the high shear action of the colloidal mixing pump Piston grout pump and mixer is durable and efficient. It is designed to meet the high-shear colloidal mixing st

Description LGP800/1200/200PI D 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 or bentonite is 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 plant is full hydraulic drive with a diesel engine. Grouting pressure and displacement are step-less adjustable. Compact size and it is easy to operate. It also takes up a small space. Featu r e Ø   55KW air cooling diesel engine as the power, it is suitable for field construction Ø   Pump output is 0-200L/min. Pump pressure is 0-5Mpa. All step-less adjustable. Ø   Simple structure, light weight, easy maintenance Ø   Double-cylinder and

1.     Construction process Pile foundation grouting technology as following shows 2.     Main technology Pre install the grouting pipe and grouting valve in the reinforcement cage. After a certain period time of being a pile, pile side grouting and pile bottom grouting is needed. The grouting method can reinforce pile bottom sediment and pile side mud. It play a reinforcement role for pile bottom and pile side in a certain range of soil through the infiltration (coarse soil), split (fine soil) and compaction (unsaturated loose soil) grouting. The intelligent grouting technology can reinforce pile side resistance and pile end resistance. Improve the vertical and horizontal bearing capacity of single pile. Reduce the settlement and horizontal deformation. Under the condition of optimizing the process parameters, the vertical bearing capacity of single pile can be increased by 50% ~ 120%. The horizontal bearing

High quality grout mixers (colloidal mixers) is used for cement, ultra-fine cement, bentonite and other admixtures, it has excellent mixing quality. High shear high speed grout mixer can also work with agitator. The agitator can storage mixed cement liquid and also avoids sediment. Mixer and agitator ensure a continuously working in grouting projects. The grout mixers for sale shown are skid mounted unit for tunnel or mining applications. The unit can be supplied on a site mobile chassis if required. All components are easily accessible for operating, cleaning and maintenance. Best grout mixers are widely used in post tensioning, tunnels, shafts and mining application. Also widely used in Building Construction- Post Tension, Highway, Highway- Slab Raising, Municipal- Slab Rasing LMA3500-650D diesel power grout mixer and agitator had been order by one of our customers in USA. It has high quality with competitive price. For more information about

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
