description	The invention discloses a shield end reinforcing method, which solves the problem of ground subsidence or ground collapse caused by stratum loss in shield work. Sleeve valve pipe grouting reinforcement is used for reinforcing the end ground, and the sleeve valve pipe grouting reinforcement comprises the following steps of (1) leveling the ground which needs to be reinforced, positioning the drilling position by using a positioning instrument, and drilling by using drilling equipment; (2) preparing and replacing a sleeve shell material; (3) inserting a sleeve valve pipe into a drill hole after the sleeve shell material is replaced; and (4) grouting to reinforce the ground after the sleeve shell material is cured. According to the shield end reinforcing method, the sleeve valve pipe grouting reinforcement method is used for grouting the ground quickly and evenly, and the sleeve valve pipe and the sleeve shell material are matched to prevent cement grout from flowing up and down, so that the cement grout can onl
