This invention discloses a trenchless removal device and method for abandoned pipelines. A vibrating device and a grouting pipe are installed on an electric trolley. Before removal, the trolley vibrates the abandoned pipeline back and forth to reduce the density of the surrounding soil, facilitating removal. Before grouting, an air bladder is inflated so that it abuts against the inner wall of the abandoned pipeline, sealing the gap between the grouting pipe and the abandoned pipeline to prevent concrete from flowing back into the abandoned pipeline during grouting. Grouting is performed simultaneously with pipeline removal, promptly filling the voids left after removal. The concrete solidifies rapidly after flowing out of the grouting pipe, minimizing ground settlement. This construction method efficiently removes underground pipelines, completing the removal and grouting processes in one operation, offering advantages such as high safety and efficiency.
