The present invention relates to grouting for waterstop and ground reinforcement of soft ground. More specifically, the objective of the present invention is to suggest a high-functional injection material mixed with inorganic alumina powder, a vegetable foaming agent and acrylic polymer, a grouting material containing the high-functional injection material, an injection device for mixing, producing and injecting the grouting material to the ground, and a grouting method using the grouting material having the high-functional injection material, and the injection device. Thus, grouting construction performance and durability of the construction are enhanced. The grouting material can be environmental-friendly as the use of conventional materials causing environmental contamination is minimized. The injection performance of the grouting material is enhanced even in the case that the material is injected into the soil with large pores. Leaching is inhibited as flexural strength and ground adhesion of the structure are increased after the construction. The grouting material can be utilized effectively on site by being mixed and injected on site. The material has an excellent rapid-hardening performance regardless of weather conditions so uniform construction performance can be obtained. The grouting material has an effect of minimizing ground deformation by enhancing flexural strength and ground friction thereof. |
