Method for forming grouting hole and grout discharging hole through steel bar grouting connection

The invention relates to a method for forming a grouting hole and a grout discharging hole through steel bar grouting connection. The method comprises the following steps: a, a grouting sleeve is positioned firstly, the directions of a grouting opening and a grout discharging opening are adjusted, and the grouting sleeve and a template are fixed through a fixing device; b, elastic pulling rods areinserted in the grouting opening and the grout discharging opening of the grouting sleeve correspondingly, and the outer ends of the pulling rods extend outside the surface of a building component; and c, concrete pouring and curing are conducted, and after final setting of to-be-poured concrete, the pulling rods are pulled out from the interiors of the grouting opening and the grout dischargingopening. The pulling rods are pulled out from the grouting opening and the grout discharging opening after final setting of the concrete and can be reutilized, a construction process is simplified, and the cost is lower; and a
