Additives for grout injection material Grout injection material containing the same Pressurization device for grouting process Grouting process using the same

摘要

The present invention relates to additives for a grout injection material, a grout injection material containing the same, a pressurization device for a grouting process, and a grouting process using the same and, more specifically, relates to a pressurization device for a grouting process and a grouting process using the same, which can minimize a loss of an injection material when injecting grout by pressurizing an upper stratum of a target section, and enable the grout to be effectively injected. Moreover, the present invention relates to a grout injection material used for the grouting process and additives for a grout injection material capable of improving material properties of the grout injection material.
