Check valve type simultaneous injection steel pipe and construction method using the same
The present invention relates to a check valve type simultaneous injection steel pipe and a construction method using the same, wherein an expanding agent is applied to form an internal simultaneous injection compartment and a check valve is used to prevent backflow when a grouting agent is injected. The check valve type simultaneous injection steel pipe (10) includes a simultaneous injection steel pipe (100), a closing cap (110), a grouting injection pipe (111), a grouting hole (112), a grouting liquid check valve (113), a closing cover (114), an expanding agent fixing plate (115), an expanding agent (116), an expanding agent injection hole (117), a spacer (118), a caulking packer (119), a caulking liquid injection pipe (120), and a caulking liquid check valve (121).
본 발명은 팽창제를 적용하여 내부 동시주입 구획을 형성하고, 체크밸브를 이용하여 그라우팅제 주입시 역류를 방지하도록 하는 체크밸브식 동시주입 강관 및 이를 이용한 시공방법에 대한 것이다.
