Grouting equipment

    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

   The underground engineering construction is affected by geological conditions, construction quality and other factors, and there will be structural leakage, building settlement, uplift at the bottom of the pit, local collapse and other dangers. Waterproof plugging and grouting technology is a kind of plugging construction technology with simple equipment, convenient construction and quick effect. It has been applied in grouting injection and rescue. https://www.leadcrete.com/grout-pump/high-pressure-vertical-grouting-pump.html Grouting injection technology is not only a construction technology, also widely used in chemical, mechanical, geology, etc. Now the grouting injection technology are a combined technology. Usually, the purpose of grouting are mainly as below: reinforcement of strata and water plugging, improve the strata the bearing capacity and steady, improve the strata gas tightness. Or in shot: Stabilisation, Strengthening, and Sealing. https://www.leadcre

Drilling for grouting is one of the import purpose of drilling projects. And mainly four applications for grouting: grouting for dams etc; Sub-surface grouting; grouting for foundation; grouting in connection with constructions. We handle many different drilling grout pump such as: plunger type grout pump, piston grout pump, screw grout pump (also named progressive cavity grout pump). Also for the grout pumps, we have mechanical type and hydraulic type for different drilling projects using.                                       https://www.leadcrete.com/grout-pump/ Leadcrete grout pump is suitable for grouting water, cement, bentonite and fine cement, non-shrink cement material. As for the drilling grout pumps power, we have electric motor, diesel engine and air powered for clients option. Different power of the grout pumps are suitable for different working site. Also a wide range suitable for the working conditions. Small grout pumps can be used to fill small void

Grouting pump, it is also named injection pump. It could be divided to electric grouting pump, diesel engine grouting pump, and manual grouting pump. Heavy duty grouting pumps are designed to pump a wide variety of high viscosity slurry and grouts. Especially in tunneling and dam grouting construction. The grouting technology is widely used in high-rise building grouting, hydro-power stations, sea ports, docks etc various pressure grouting, foundation treatment, soft foundation reinforced grouting, backfill grouting anchor support in tunnel mine subway construction. For the moment, the main application of the grouting process includes compact grouting, anchor support grouting, curtain grouting, and high-pressure jet grouting etc.                                    https://www.leadcrete.com/grout-pump/ Leadcrete grouting pumps are available in various sizes and power ratings with grout injection pressure up to 500 bar and flow rates up to 1500 L/min. Leadcrete as the pr

The grouting injection technology will improve the soil strength and the modulus of deformation. It will decrease the soil permeability, improve the anti- permeability. This is widely used during the microtunneling and tunneling projects. During the grouting projects, colloidal grout mixers & pumps are the necessary equipment. The basic theory grouting is that the grout should be slowly injected and penetrated into the voids to replace the fluids in the formation voids without disturbing the skeleton of the soil. The results of such procedure is to improve waterlightness, deformability and strength of the natural soils. Using the grouting and injection technique, the homogeneous and continuous improvement effect of the solidified soil will be improved. So the foundation will be much steady. https://www.leadcrete.com/grout-mixer-and-agitator/ Colloidal grout mixer & pump including a colloidal grout mixer, grout agitator and a grout pump. Mixer agitator and pump

A colloidal grout mixer uses a high speed impeller to generate a shear vortex. A grout agitator uses a low speed impeller creates a low rotational force, it is used to prevent the mix becoming solidify. LMA500-1000E is the most hot selling grout mixer and agitator . Mixer volume is 500L, and agitator volume is 1000L. Electric motor is equipped. Suitable for the working site that power supply is convenient. The grouting mixer and agitator has a working platform, it is easy loading of cement bags and working. The colloidal mixing equipmen t unit rapidly and efficiency mix various types of grout which can includes cement, bentonite and sand.
