摘　　要：随着盾构施工技术的逐渐成熟,在地下空间施工中,盾构施工技术的应用越来越广泛。现场根据图纸完成工作井施工及盾构推进。在盾构接收时,为降低富水地层盾构接收风险,一般情况下,需要对盾构盾尾部位进行二次注浆(环箍)。根据不同的施工工艺,二次注浆材料也不同,其根本目的为止水,以减少盾构机接收风险。As the shield construction technology is more and more mature,now the underground space construction of shield construction technology is more and more widely used,the site according to the drawings well construction and shield propulsion,when receiving shield,to reduce the risk of rich water formation shield receiving,in general,the need to shield tail for secondary grouting,the term“hoop”,according to different construction technology,secondary grouting material is also different,its fundamental purpose of which is to stop water and reduce the risk of shield machine receiving.
