     The grouting mixer pump were made by GAODE Equipment were widely used for mixing and grouting cement slurry when build high building.      The grout mixer pump was one high shear grout mixer, agitator, grout pump all-in-one,      Gaodetec has many types grout mixer pump were used for building grouting. https://www.gaodetec.com/grout-pump-and-mixer/       The most popular is GGP300/300/75PI-E , the high shear grout mixer volume is 300L, agitator volume is 300L, there are two stages for pressure, that’s low pressure and high pressure, when at low pressure stage, the pressure is 0-50 bar, grout flow is 0-75L/min, when at high pressure stage, the pressure is 0-100 bar, flow is 0-38L/min.                             https://www.gaodetec.com/grout-pump-and-mixer/       The grout mixer pump for mixing and pumping cement slurry has following advantages: 1.     Continuous output with small pulse or kicks or jerks 2.     Grouting pressure and flow both co

    The performance and quality of the grouting pump play a decisive role in the safety, quality and efficiency of the grouting project. If the choice of grouting pump is blind and random, it may cost a lot to fail to achieve the expected results, and even cause engineering accidents. Grouting method is to hydraulically pump the slurry into the rock or soil gap and fill it with compaction. During the grouting process, new cracks will be punched out, which will cause frequent changes in grouting pressure. Sometimes the grouting pressure will be sharply sharp. Changes, the characteristics of this condition determine the performance of the grouting pump application. https://www.leadcrete.com/grout-pump-mixer/electric-grout-station.html The grouting pump application instruction: (1) The grouting pump should have a larger range of slurry discharge adjustment, and the change of the final amount of grouting and the amount of grouting is 8~10 times. The final amount of grou

    Double-Plunger hydraulic grouting pump for cement, is designed with two low-wear plungers pump. With the features of double acting, ball valves, low-pressure surge, variable pressure, and flow. Therefore, this pump is suitable for all grouting work, up to 8mm particle size, such as, for the pumping of backfill mortar behind tunnel liners, grouting in the soil, earth foundation stabilization, waterproofing, tunnel lining, underwater foundations, bridge decks, deep well casing, slope line grouting, etc.     Feature of mobile grouting pump :     The plunger pump system     Comparing with the piston pump system, the plunger system does not require any close tolerance parts such as cylinders or precise piston seals, etc. The plunger is sealed by a simple maintenance-free seal     Double plungers and acting     Vertical type pump with compact size     Hydraulic drive     Safely releasing pressure when pumping block     Ball valve     Up to 8mm particle size

      Grouting injection pump is a very important machine in grouting project. Following are classification of grouting and analysis of application conditions.       According to the purpose and function of grouting, grouting can be divided into water blocking grouting and reinforcement grouting. According to the order of the work, it can be divided into pre-grouting and post-grouting.       The purpose of water shutoff and grouting is to block the groundwater from intruding into the working surface and facilitate construction. The requirements for the slurry material are: the gel time is short, and it can be easily and accurately controlled within a certain range, but the strength is not required to be high, and it is suitable for the rocky hard and large water-bearing formation.        The purpose of reinforced grouting is mainly to reinforce the surrounding rock, so that a certain range of surrounding rock is cemented into a force ring, which has higher           requirement

       Grouting equipment and machinery is to press the solidified liquid into the gap between the formation and the structure under a certain pressure, and to fill and solidify, so as to improve the performance of the formation and structure, and to strengthen and stop the water. The process of injecting slurry into the soil is generally first infiltrated. When the passage is blocked, the slurry is difficult to penetrate, that is, the surrounding formation is compacted. When the pressure continues to rise, the soil is cleaved, and the slurry further spreads along the crack. Infiltration, compaction and splitting affect each other and complement each other, which together play a role in improving soil integrity and strength and reducing formation permeability and water content. Permeate grouting is the filling of voids or fissures, the release of free water and gas in the pores, without changing the structure of the soil. The method of diffusion depends on the way the grout is made.
