The invention provides a building scheme of a dam-free hydropower station. A main dam with a high drop does not need to be built, only multiple retaining dams with low drops need to be built on an original riverway, meanwhile, a water diversion pipeline enabling an upstream reservoir area to directly communicate with a downstream reservoir area is built, a straight line erecting manner is adoptedin the water diversion pipeline, the water flow speed is not obstructed, a chain type hydroelectric generation system is adopted, theoretically, water flowing energy can be subjected to 100% absorbing, multiple cascade reservoirs formed by the retaining dams basically keep ecological environment and natural landscape of the original riverway while efficient power generation is achieved, and therefore immigration is not needed. The original riverway is changed into a reservoir, a channel becomes deep and wide, the ship tonnage can be increased, the number of sailing boats can be increased, theboat sailing speed can be increased, and the aquaculture benefits can be increased while the navigation benefits are greatly improved.
本发明提出了一种无坝式水电站的建造方案，无需建造高落差的主坝，只在原河道上修建多个低落差的挡水坝，同时，修建上游库区直通下游库区的引水管道；引水管道采取直线架设的方式，对水流流速无阻碍，采用链条式水力发电系统，理论上可以使水流动能得到100%的吸收，在实现高效发电的同时，挡水坝形成的多个梯级水库，基本保持了原河道的生态环境和自然景观，所以不用移民；原河道变成水库，航道变深、变宽，既能增大船舶吨位，又能增加行船数量，还能提高行船速度；在极大提高航运效益的同时，还能增加水产养殖效益。
