Detailed Description

It should be noted that, in the present embodiment, the directional terms are only described according to the drawings, and do not limit the present invention.

The present invention will be described in detail with reference to the accompanying drawings: a grouting sleeve capable of ensuring grouting quality comprises an embedded grouting pipe 1 and an external grout outlet pipe 2, as shown in figure 1; as shown in fig. 2, the external grout outlet pipe 2 is composed of a vertical pipe 3, a turning and transverse pipe 4 and a circular truncated cone-shaped pipe 5 extending into the embedded grout pipe. Wherein, the joint of the turning and transverse pipe 4 and the round platform shaped pipe 5 extending into the pre-embedded grouting pipe is provided with a thin-wall structure 6, the pipe wall of the thin-wall structure 6 is very thin, so that the vertical pipe 3 and the turning and transverse pipe 4 can be conveniently broken and removed after grouting; the outer diameter of the circular truncated cone-shaped pipe 5 extending into the embedded grouting pipe is gradually changed, so that the circular truncated cone-shaped pipe is conveniently inserted into the embedded grouting pipe 1; a limiting structure 7 is arranged at the joint of the round platform-shaped pipe 5 extending into the embedded grouting pipe and the turning and transverse pipe 4, the limiting structure 7 can limit the external grout outlet pipe 2, particularly the thin-wall structure 6, outside the component 100, so that the external form of the component is not influenced after the vertical pipe 3 and the turning and transverse pipe 4 are broken and removed after grouting.

As shown in fig. 3, the pre-buried grout pipe 1 consists of a vertical pipe 8, a grout inlet 9 and a grout outlet 10, wherein the grout outlet 10 and the grout inlet 9 are respectively arranged at the upper end and the lower end of the vertical pipe 8 and are positioned at the same side; the circular truncated cone-shaped pipe 5 extending into the embedded grouting pipe is inserted into the grout outlet 10.

As shown in fig. 4, the embedded grouting pipe 1 is vertically embedded in the member 100, the ends of the grout inlet 9 and the grout outlet 10 are flush with the side surface of the member 100, and the specific operation flow is as follows:

1. when the production component 100 is prefabricated in a factory, placing the embedded grouting pipe 1 according to the design requirement;

2. assembling prefabricated components on a construction site;

3. before grouting, the circular truncated cone-shaped pipe 5 of the external grout outlet pipe 2 extending into the embedded grout outlet pipe is inserted into the grout outlet 10 and fastened as much as possible (the round and transverse pipes 4 can be knocked by a hammer);

4. during grouting, grouting is performed from the grout inlet 9 until grout is ejected from the vertical pipe 3 externally connected with the grout outlet pipe;

5. after discharging the slurry for a period of time, plugging the top of the vertical pipe 3 by using a plug;

6. after the slurry is solidified, the lateral knocking (capable of being knocked by a hammer) is carried out on the turning and transverse pipe 4, so that the external slurry outlet pipe is broken at the thin-wall structure 6.

It should be noted that, in the actual use process, the embedded grouting pipe 1 may be vertically placed (for example, in the above embodiment), or may be horizontally placed or obliquely placed in the member; no matter how the embedded grouting pipe is placed, the elevation of the pipe top is far higher than the elevation of the grout outlet of the embedded grouting pipe only by ensuring that the external grout outlet pipe 2 is installed. For example: the embedded grouting pipe 1 is transversely placed, the opening ends of the grout inlet 9 and the grout outlet 10 are upward, and then the turning on the external grout outlet pipe 2 and the transverse pipe 4 are directly designed into a vertical pipe.

The above embodiments are merely illustrative of the present invention and should not be construed as limiting the present invention. In order to ensure good sealing performance, the external slurry outlet pipe is of an integrally formed structure, or of course, a split structure is adopted, and all the parts are assembled into the external slurry outlet pipe. It will be understood by those skilled in the art that any extension, modification or the like made without departing from the principles of the present invention is within the scope of the present invention.
