Method for filling used pipe and underground cavity
The present invention relates to an underground disuse-pipe and cavity filling method in which repair can be performed by injecting filling materials into a cavity without removing road pavements, and filling materials are tightly injected and strength is guaranteed. According to the present invention, the underground disuse-pipe and cavity filling method comprises the steps of: forming a filling material injection hole connected to a cavity to be repaired; connecting an injection pipe from a storage tank in which a high fluidity filling material to be filled in the cavity is stored to the injection hole; and supplying a thickener to the end of the injection pipe so that it is mixed with the high fluidity filling material and curing the filling material.
본 발명은 지중 폐관 및 공동 충진방법에 관한 것이다. 본 발명에 따른 지중 폐관 및 공동 충진방법은, 보수 대상이 되는 공동과 연결된 채움재 주입공을 형성하는 단계, 공동에 충진될 고유동성 채움재가 저장되어 있는 저장조로부터 주입공까지를 주입배관으로 연결하는 단계, 주입배관의 말단에 증점제를 공급하여 고유동성 채움재와 혼합되도록 하는 단계 및 채움재가 경화되는 단계를 포함하여 이루어진 것에 특징이 있다.
