And a cementing material is extruded between the precast concrete stud and the precast concrete sleeve.

The cementing material is asphalt cement.

And an embedded part is arranged in the precast concrete stud, so that the embedded part concrete stud is formed.

And the end part of the embedded part concrete stud is provided with a wrench jack.

The beneficial effects created by the invention are as follows:

1. the construction speed of hole plugging is accelerated, and the main process of original hole plugging is as follows: base course treatment → formwork support → concrete pouring (or material filling such as fire prevention) → curing → formwork removal → surface treatment (sanding, waterproofing, rust prevention and the like). The hole plugging process comprises the following steps: cleaning in the sleeve → screwing in the concrete bolt → surface treatment (cleaning, rust prevention, etc.).

2. The hole plugging quality is guaranteed, the concrete bolts are all prefabricated, and the plugging quality is guaranteed from the source.

3. The installation of the embedded part can be independently carried out, the embedded part is prevented from influencing the subsequent process construction, and the accurate installation position and the use safety are ensured.
