In the construction process of shear wall, it is often necessary to reserve holes to meet the installation requirements of subsequent pipelines, cables and other facilities. The traditional method of reserving holes is to fix a steel sleeve on the reinforcement mesh of the shear wall, then fill sawdust or old cotton in the sleeve, seal the two ends of the sleeve with adhesive tape, and finally pour concrete. After the concrete dries, the adhesive tape at both ends of the sleeve is torn off and the filler inside is removed, and a reserved hole is obtained on the shear wall. However, during the pouring of concrete, the steel sleeve is prone to deformation due to the pressure of the concrete, affecting the installation of subsequent facilities.
