摘要
A grouting steel pipe for ground reinforcement having spirally arranged injection ports and a steel pipe grouting method using the same are provided to minimize the loss of internal force by an injection port in case of applying force vertically or horizontally, and to improve the anchoring force of the ground by guiding the dispersion effect of a grouting solution. A steel pipe grouting method using a grouting steel pipe for ground reinforcement comprises the steps of: penetrating and installing a grouting steel pipe(P) for ground reinforcement having spirally arranged injection ports in the earth; and injecting a grouting solution to the inside of the grouting steel pipe for ground reinforcement having the spirally arranged injection ports including the steps of forming a double pipe by having a grouting steel pipe for ground reinforcement having the spirally arranged injection ports as an outer pipe and installing an inner pipe having a spacer to the inside of the outer pipe, and injecting a grouting solution between the inner pipe and the outer pipe.
