Problems solved by technology
In the construction of prefabricated components, soft corrugated pipes are easily crushed by concrete, which makes it difficult for later grouting
The straight pipe grouting sleeve has the problem of insufficient grouting caused by the grout running out of the grouting hole when the grouting machine is withdrawn after the grouting is completed
The use of rubber plugs to block the sleeves not only requires hammers and other tools to force the rubber plugs into the sleeves during construction, but it is often difficult to control the quality of the plugs and cause them to fall off and cause pulp to run

The invention discloses a novel grouting sleeve. The novel grouting sleeve comprises grouting pipes, grouting plug covers and plugging devices, wherein the grouting pipes are connected with a reinforcement connecting sleeve; each plugging device is connected with the corresponding grouting plug cover, and each grouting plug cover is connected with the corresponding grouting pipe; each grouting pipe is designed to be of a bent structure; a connecting end of each grouting pipe is provided with external threads; each grouting plug cover includes a cylinder and an end cover; each end cover is fixed to a free end of the corresponding cylinder; each end cover is provided with a first grout outlet; the inner side of a connecting end of each cylinder is provided with internal threads fitting withthe external threads; each plugging device includes a plugging inner cover, a connecting shaft and a rotary handle; each plugging inner cover is arranged on at the inner side of the corresponding endcover; the diameter of the plugging inner covers is smaller than the inner diameter of the cylinders; and each plugging inner cover is provided with a second grout outlet. By employing such structure,the novel grouting sleeve avoids the grout runout problem caused by not full grouting and poor plugging quality of grouting plugs during grouting construction of prefabricated components, thus facilitating rapid and efficient grouting work during grouting construction.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a novel grouting sleeve and a using method thereof. Background technique [0002] At present, with the development of building modularization, the share of prefabricated buildings in the construction field is increasing. However, in traditional construction, hard straight pipes or soft corrugated pipes are used as grouting sleeves, and rubber is used for grouting. stuffed. In the construction of prefabricated components, soft corrugated pipes are easily crushed by concrete, which makes it difficult for later grouting. The straight pipe grouting sleeve has the problem of insufficient grouting caused by the grout running out of the grouting hole when the grouting machine is withdrawn after the grouting is completed. The use of rubber plugs to block the sleeves not only requires hammers and other tools to force the rubber plugs into the sleeves during construction, b...
