Performance investigation of a newly proposed drainable pipe fitting
Performance investigation of a newly proposed drainable pipe fitting
We propose a versatile drainage system that incorporates drainage inlets for pipe fittings that can connect to standard steel and PVC pipes. In existing drainage pipe systems, soil entering from small openings clogs the drainage path and is a cause for concern. With the proposed pipe fittings, however, it is possible to freely design the drainage inlet shape, position and inflow path, thereby reducing the amount of soil entering the drainage route. In this study, drainage performance and sediment control capabilities of the newly proposed drainable pipe fittings were investigated through laboratory and full-scale model experiments. Consequently, it was found that the drainable pipe fittings ultimately possessed equivalent drainage performance to conventional drainage pipes with better control of sediment discharge. Further inlet shape improvements can provide effective drainage systems for geotechnical engineering sites.
