[0002] Recycled concrete tee fittings are widely used in water supply and drainage systems, HVAC systems, and other areas within the construction industry. Traditional tee fitting manufacturing methods typically utilize cast-in-place or precast technologies. However, cast-in-place methods have certain limitations. They require on-site construction, are time-consuming, and are significantly affected by weather conditions. While precast technology can be completed in a factory, improving production efficiency, the precast mold structure is relatively fixed and difficult to adjust. Different molds are required for different product sizes, which is time-consuming and labor-intensive to replace. Furthermore, disassembly and assembly are generally difficult, operation is complex, and reuse rates are low, increasing costs and workload.
