HIGH-EFFICIENCY GROUTING SYSTEM

摘要

PURPOSE: A high-efficiency grouting system is provided to maximize the injection efficiency by improving the permeability of injection materials and to improve constructability by forming in a one-line loading system. CONSTITUTION: The high-efficiency grouting system comprises: a site grinder crushing thick injection materials placed to a site for grouting into ultrafine particles in a site; a high-speed shear mixer(320) breaking up ultrafine corpuscular cohesive powder by adding mechanical shear strength; a four-jaw stirrer(325) injecting suspension type injection materials supplied through the high-speed shear mixer or solution type injection materials supplied to a separate line selectively; a grout pump(330) pumping up the injection materials supplied through four-jaw stirrer at the appointed pressure; stand pipe fittings(340) injecting the injection materials supplied using the grout pump to the ground; and an automatic injection management system(350) controlling the pressure, quantity and speed of injection materials injected to the ground through the stand pipe fittings automatically within the preset range.
