Roadbed electroosmosis drainage device and roadbed
The invention provides a roadbed electroosmosis drainage device, and belongs to the technical field of drainage devices. The device comprises a plurality of electro-osmosis drainage pipes which are located between a fly ash sand cushion layer and a water-resisting layer of a roadbed and used for receiving water flowing into the electro-osmosis drainage pipes from the fly ash sand cushion layer; the electroosmosis drainage pipe comprises a drainage hard pipe and a filtering hose sleeving the upper part of the drainage hard pipe; axial conductive metal is embedded in the pipe wall of the drainage hard pipe, and a plurality of water inlets used for draining accumulated water in the roadbed into the drainage hard pipe are formed close to the upper portion of the pipe wall. The filtering hose is made of a permeable material, the contact part of the filtering hose and the water-resisting layer is hermetically connected, a cavity is formed between the filtering hose and the drainage hard pipe, and a porous filtering layer is arranged in the cavity; and water of the fly ash sand cushion flows into the cavity, is filtered by the porous filter layer and then flows into the drainage hard pipe through the water inlet. According to the invention, transformation is carried out based on an electroosmosis method, the filtering hose is made of a permeable material and is provided with a porous filtering layer, so that pipeline blockage is avoided.
本发明提供了一种路基电渗排水装置，属于排水装置技术领域。本发明包括：若干个电渗排水管，其位于路基的粉煤灰砂垫层和隔水层之间，用于承接由粉煤灰砂垫层流入电渗排水管的水；电渗排水管包括排水硬管和套设于排水硬管上部的过滤软管；排水硬管的管壁内埋设有轴向的导电金属，靠近管壁上部开设有若干用于将路基内部的积水引流到排水硬管中进水口；过滤软管为透水材料制成，过滤软管和隔水层接触的部位密封连接，过滤软管和排水硬管间形成腔体，腔体内设置有多孔过滤层；粉煤灰砂垫层的水过滤软管流进腔体，经多孔过滤层进行过滤后经进水口流入排水硬管内。本发明基于电渗法进行的改造，过滤软管为透水材料和设置多孔过滤层，避免了管道堵塞。
