STEEL PIPE REINFORCING GROUTING METHOD USING SIMULTANEOUS INJECTION STEEL PIPE AND GROUT
The present invention relates to a steel pipe reinforcement grouting method using a simultaneous injection steel pipe and a grout material. The steel pipe reinforcement grouting method using a simultaneous injection steel pipe and a grout material comprises the steps of: (a) forming a plurality of drilling holes (20) (S10); (b) inserting a simultaneous injection grouting steel pipe (30) into the drilling hole (20) (S20); and (c) after step (S20), spraying a two-component grout material through a hose (40) and performing simultaneously injection for the surrounding area of the drilling hole (20) without sealing (S30). In step (S10), the drilling hole (20) ensures that no steel pipe exists in a drilling hole section to be removed by excavation when excavating a final surface (B). In step (S20), the grouting steel pipe (30) is a pre-perforated simultaneous injection steel pipe and comprises a first injection hose (41) for rear injection, a second injection hose (42) for tip injection, and a filling confirmation hose (43) for air discharge which extend to the outside of a steel pipe cap, wherein each of the hoses is supported by a ring-shaped partition (36). Accordingly, a grouting construction period can be shortened.
본 발명은 동시주입용 강관과 그라우트재를 이용한 강관보강 그라우팅 공법에 관한 것으로서, (a) 다수의 천공홀(20)을 형성하는 단계(S10), (b) 동시주입 그라우팅 강관(30)을 상기 천공홀(20)의 내부에 삽입하는 단계(S20), (c) 상기 S20 단계 이후, 호스(40)를 통해 2액형 그라우트재를 분사하여, 천공홀(20)의 주변영역을 씰링없이 동시주입하는 단계(S30)를 포함하는 동시주입용 강관과 그라우트재를 이용한 강관보강 그라우팅 공법에 있어서, 상기 S10 단계에서, 상기 천공홀(20)은, 막장면(B) 굴착시 굴착에 의해 제거될 천공홀 구간에는 강관이 존재하지 않도록 하고, 상기 S20 단계에서, 상기 그라우팅 강관(30)은, 선천공 방식의 동시주입 강관으로서, 후미부 주입용 제1 주입호스(41)와, 선단부 주입용 제2 주입호스(42)와, 공기배출을 겸하는 충전확인호스(43)가 강관 캡의 외부까지 연장되어 구비되고, 상기 각 호스들은 링 형상의 칸막이(36)에 의해 지지되는 것을 특징으로 한다.
