- Abstract:
- The reduction in flushing volume may cause solid deposits and blockages in the building drainage horizontal pipes for the current large?scale use of water?saving appliances. Based on expounding the composition and shape characteristics of solid waste in the drainage pipeline, the influences of sanitary appliance type, water discharge, pipe roughness, slope, pipe diameter and elbow on the transport distance of solid waste were studied, respectively. The research results showed that the shape, size and density of solid wastes are the internal factors that affect the transport distance of solid. The transport distance of the solid waste would be increase with the improvement of the peak flow rate of the toilet drainage. Additionally, increasing the curvature radius of the elbow would cause lower energy loss when the flow turns and longer solid transport distance. The parameters such as the slope and pipe diameter of the horizontal pipe can be optimized under small discharge of the toilet. Appropriate measures such as increasing the slope of the horizontal pipe or reducing the pipe diameter were taken to increase the transport speed and distance of solid waste in the horizontal pipe.
