In concrete engineering, the reinforcing steel bars need to be exposed outside the mould to ensure the connection strength of concrete, but gaps exist between the exposed reinforcing steel bars and the concrete mould, and the problem of slurry leakage can occur in the gaps between the reinforcing steel bars and the concrete mould during concrete pouring construction. The common grout stopping method of tightly binding wires after the on-site reinforcement is finished and tightly winding the high-density sponge close to the template has low work efficiency, large material waste and environmental pollution. And the sponge can be extruded and displaced by cement slurry in the construction process to cause slurry leakage. Slurry leakage in concrete construction not only causes material waste and influences construction quality, but also increases later renovation and rework loss and also causes adverse effects on construction work efficiency. Therefore, it is desirable to provide a grout stop member with good sealing effect, reliable connection and convenient installation, which is used for sealing the gap between the steel bar and the concrete mold. .
