S-shaped grout outlet pipe for prefabricated part

Abstract

The invention discloses an S-shaped grout outlet pipe for a prefabricated part. The S-shaped grout outlet pipe is divided into four sections. The pipe diameters and the wall thicknesses of all the sections are consistent. A first section is a straight section, the front end of the first section is horizontally connected with a grout outlet hole of a grouting sleeve, and the rear end of the first section is in sequential connection transition with the second section; a second section is a circular arc section, the front end of the second section is horizontally connected with the first section, and the rear end of the second section forms an angle of 45 degrees with the horizontal direction and is in transition connection with a third section; the third section is a straight section and is in transition connection with the second section and a fourth section; and the fourth section is an arc section with the angle of 45 degrees, the front end of the fourth section forms an angle of 45 degrees with the horizontal direction and is in sequential transition connection with the third section, the rear end of the fourth section is the outer end part of the grout outlet hole, and a rubber plug is used for plugging after grouting is completed. The S-shaped grout outlet pipe can generate a backflow grout supplementing effect, about 75 percent of grouting materials in the grout outlet pipe can be used for grout supplementing, and no bubble is enabled to appear in the grouting sleeve. The S-shaped grout outlet pipe is a whole, the straight section and the arc section are in sequential connection without a sharp turning phenomenon, and the whole S-shaped grout outlet pipe is high in outside and low in inside after being installed.

Description

technical field [0001] The invention relates to an S-shaped grout outlet pipe for prefabricated components, and belongs to the technical field of concrete prefabricated grouting. Background technique [0002] At present, most of the pipes used in the grouting hole of the vertical component grouting sleeve are plastic corrugated pipes, and the corrugated pipes are connected to the grouting hole of the grouting sleeve and placed horizontally. [0003] At present, the grouting construction of vertical components mostly adopts the method of one-point grouting. When the grouting material flows out in columnar form in other grouting holes and grouting holes, rubber plugs are used to block them in time. After all the grouting holes and grouting holes are completely blocked, pull out the grouting pipe and immediately seal it with a rubber plug. The grouting material will flow out between the time when the grouting pipe is pulled out and the rubber plug is blocked, which may cause t...

AI Technical Summary

Problems solved by technology

The grouting material will flow out between the time when the grouting pipe is pulled out and the rubber plug is blocked, which may cause the liquid level of the grouting material in the grouting sleeve to drop, because the grouting hole is placed horizontally and communicated with the grouting sleeve , it may cause the liquid level of the grouting material in the grouting pipe and the grouting sleeve to drop as a whole, and then the grouting in the grouting sleeve is not dense.
