Abstract
An integrated hole sealing, device includes a capsule plug, an outer capsule having a first hole site, an inner capsule having a second hole site, a capsule water injection pipe, a borehole water injection pipe and a tapered plug. Two ends of the outer capsule and the inner capsule are respectively fixed on the capsule plug and the tapered plug. The capsule plug, the tapered plug, the outer capsule and the inner capsule form a closed hollow cylindrical cavity. A middle part of the inner capsule is a hollow pipeline, and two ends thereof respectively correspond to the first and second hole sites. The borehole water injection pipe passes through the hollow cylindrical cavity. A part, located in the hollow cylindrical cavity, of the borehole water injection pipe is telescopically wound outside the inner capsule. The capsule water injection pipe passes through the capsule plug and extends into the hollow cylindrical cavity.
