The apparatus of the present invention comprises a guide pipe (30) including: a small-diameter part (31) having a smaller diameter than a pipe (10) and coupled with the tip of the pipe (10); and a large-diameter part (33) connected with the small-diameter part (31) by a taper part (32) and accommodating a sponge pig (20) therein. Therefore, while penetrating from the large-diameter part (33) to the small-diameter part (31) by the towing of a towing loop (24), the sponge pig (20) is contacted and inserted into the pipe (10).</p> |
