Description

TECHNICAL FIELD

[0001] The present application relates to the field of grouting technology, in particular to a portable anchor rod hole sealing device. BACKGROUND

[0002] In the process of tunnel construction, anchor rod anchoring is often used to maintain the stability of surrounding rock. After installation of the anchor rod, a part of the hole is left, and grout is needed to seal the hole. The traditional sealing mode is to prepare grout outside the hole, and then transport the grout to the corresponding position through a conveying pipeline for grouting. Since the position of the hole left by the anchor rod is far away and less grout is needed for sealing the hole, this grouting method causes low work efficiency and serious waste of grout in the conveying pipeline.
