| titleOfInvention | Double-layer drainage guard system |
| abstract | The present invention relates to double-layer drainage guard system, the double-layer drainage pipe duct of specifically a kind of rain sewage diversion belongs to municipal drainage technical field.It includes pipe duct main body, and waist is equipped with membrane support in pipe duct main body, and by connector connection elastic baffle in membrane support, pipe duct main body internal channel is divided into upper layer and lower layer by elastic baffle, and upper layer is rain water channel, and lower layer is sewage routeway；Elastic baffle is equipped with cutoff hole, and cutoff hole, which is arranged right below to shut off, limits valve, it is big in lower layer's sewage quantity and when oilysewage surface being caused to rise, ball-cock assembly is taken up by the buoyancy of sewage and blocks cutoff hole.Cover board is equipped at pipe duct main body upper end opening, cover board covers the opening of pipe duct main body, is uniformly provided with multiple drain holes on cover board.Rain sewage pipe duct can be laid with position and be realized the initial rainwater that shuts off by the present invention, reach that the small scale of construction, variable capacity, buried depth are shallow, occupy little space, is with low investment, the use purpose of easy access maintenance. |
