Hole packer for horizontal drilling of airport runway base layer

The utility model provides a hole packer for horizontal drilling of an airport runway base layer, and belongs to the field of drilling grouting sealing research. According to the utility model, the plugging piece is additionally arranged in the grouting pipe, and the threading pipe orifice is plugged by the plugging piece in the grouting process, so that slurry flows into the horizontal drill hole from the space between the pipe wall of the threading pipe and the inner wall of the grouting pipe to realize backfilling, and the slurry does not plug the threading pipe, thereby facilitating the subsequent maintenance of the navigation-aid lamp cable in the threading pipe. 本实用新型提供了一种机场跑道基层水平钻孔用的封孔器，属于钻孔注浆密封研究领域。本实用新型通过在注浆管内增设封堵件，在注浆过程中，通过封堵件来堵住穿线管口，使得浆液从穿线管管壁和注浆管内壁之间流入水平钻孔中实现回填，且浆液不会堵塞穿线管，便于后续维护穿线管中的助航灯线缆。
