摘　　要：注浆钻头的发展一直落后于注浆工艺及浆液材料的发展。介绍了一种新型伸缩式注浆钻头,凭借其特性可实现在大部分土层中、任意深度边钻边注,推荐了配套合理的施工方法、施工顺序和施工参数,成功应用在青岛地铁R3线隧道工程中,缩短了注浆工期。并采用多种方法验证其注浆效果,证明该新型钻头在海岸沉积复杂地层中的适用性。Grouting bit development has lagged behind the grouting process and the development of slurry materials. A new telescopic grouting drill bit is introduced in this paper, it can be realized while drilling edge drilling in most of the soil and any depth by virtue of its characteristics, the reasonable construction method, construction sequence and construction parameters are recommended, successfully applied it in the Qingdao Metro Line R3 tunnel project and shorten the grouting period. The grouting effect was verified by various methods, and proved the applicability of the new drill bit in the complicated sedimentary strata.
