The utility model discloses a connecting structure of a clip-type round anchor plate and a mud jacking steel cap. The connecting structure comprises an anchor plate and a mud jacking steel cap, wherein the end part of the mud jacking steel cap is connected with a mud jacking steel pipe; a valve is arranged in the grouting steel pipe; an annual blocking table is arranged in the interior of the mud jacking steel cap; a rubber ring is arranged at the matching part between the annular blocking table and the anchor plate; the end part of the anchor plate is provided with external threads; the end part of the mud jacking steel cap is provided with internal threads that are matched with the external threads. The connecting structure solves the problem of non-dense mud jacking caused by fracturing of the anchor head to cause leakage, causing waste due to blocking of the anchor head by cement mortars, and the problem of serious bleeding of slurry in the end part of the pipe is effectively avoided.
