Ultra-high pressure ground grouting method

摘要

The present invention relates to a ground grouting method, and more particularly, in constructing a grout material that is improved by grouting injection into the ground, by adding sodium silicate having a gelling property to water and cement (Na2SiO3), the density of the grout material The present invention relates to an ultra-high pressure spray ground grouting method to effectively block soil loss and groundwater flow by improving cement and soil pores and cavities, thereby improving solidity and strength with soil.
