High Pressure Jet Grouting Technology Overview high pressure jet grouting method is generally used after a project to design depth of drilling rigs, drilling rig equipment walking Churning occurs with high-pressure mud pump, drill through special nozzles installed in the machine side, the surrounding soil injection chemical grout (cement slurry used), but to a certain speed drill slowly improved, high-pressure jets destroyed the structure of soil near and forces mixed with chemical grout, hardened into a uniform diameter cylinder in the foundation. Can also be adjusted to enhance the speed according to project needs, changes in injection pressure rig, or transform diameter of the nozzle, thereby changing the flow, so that the desired consolidation of the body to become designed shape. Overall diameter of the jet grouting method reliability solidification body (length) affected by soil punch appearance was irregular, hard soil consolidation diameter (length) to be smaller, high-pressure jet grouting, uniformity should be higher than normal static pressure grouting. Further core drilling rig, consolidation body in good (no concrete erosion) environment, increasing strength, the strength continues to increase rate of more than 10 years. Measured by the 10-year increase of 1.5 times or even higher. So drilling rig manufacturers, as long as the concrete without erosion of groundwater and not cold (ie freezing temperature of not less than minus 200C) conditions, body mass consolidation reliable, can be used as a permanent foundation and seepage curtain. Drilling rig manufacturers, poly strong jet grouting drilling rig injection pump, Urumqi rig provided by the Tianjin-strong high-pressure pump Limited. Tianjin-strong high-pressure pump Limited (www.tjjuqiang.com) is Tianjin, piling machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Churning rig poly strong leadership with the staff warmly welcome all inquiries negotiations to create a strong jet grouting rig gather a better future.
