Background

In the prefabricated building engineering project, after concrete prefabricated parts (PC components) are hoisted, grouting construction of component connection node positions is necessarily carried out, so that the purpose of structural connection is achieved, and sleeve grouting and threaded blind hole grouting construction are the most common. Grouting construction is an important step for connecting PC member nodes, and directly influences the structural quality of engineering projects. In the conventional grouting construction process, grouting is carried out on the grouting holes, after the situation that grouting materials overflow from the grouting holes, the grouting holes are immediately plugged by using rubber plugs or wood plugs, and after the grouting materials are hardened, the rubber plugs or the wood plugs are pulled out, so that grouting construction is completed. But there are some problems in the grouting construction process that affect the grouting construction quality. Because, among the grout process, there is certain pressure inside the sleeve, leads to rubber buffer and wooden plug to accomplish the shutoff back, drops easily, and the grout material spills over after dropping, probably causes the inside circumstances such as uncompacted of structure. In addition, probably there is the excessive grout hole of several occasionally and spills over the grout material, because of can not in time carry out the shutoff to each excessive grout hole, operating personnel often avoids the waste of grout material, can pause the slip casting, thereby leads to inside uncompacted construction quality who influences the grout.
