[0002] Grouting sleeve is also called grouting sleeve joint or sleeve grouting joint. Grouting sleeve is a combination of specially processed sleeve, matching grouting material and steel bar. When connecting steel bar, fast-hardening non-shrinkage grouting material is injected to connect steel bar and sleeve by bonding and biting action between materials. Sleeve grouting joint has the advantages of reliable performance, wide applicability and easy installation.
[0003] All grouting operations in prefabricated buildings adopt the method of plugging grouting holes and slurry outlet holes after grouting, that is, whichever hole is slurry outlet during the grouting process is plugged. However, when there are many holes, the grouting workers are prone to panic during the pressure grouting process. At the same time, the grouting holes need to be plugged after the grouting is stopped. During the period from stopping grouting to plugging the grouting holes, a small amount of slurry will flow out of the grouting holes, causing the inside of the grouting sleeve to be not full.
