Based on the available raw data and topographic map to carry on the design, the main contents are as follows:Hub layout, the selection of water turbine type, plant type, the determination of size of the spiral case, the determination of the tail pipe size, speed and butterfly valve type selection, determination of hydropower plant size,, water diversion system layout design, the workshop layout design, water diversion system, and draw the corresponding according to the hub unit, water diversion system layout, plant general layout center section map, units center profile, factory floors(generator, turbine, volute layer) plan a layout plan and section. Hydropower station is located in the longmenshan cathaysian tectonic system two big fracture of long and narrow fault block on hydrogeological conditions is simpler, mainly sand shale interlayer fissure water and quaternary pore water of loose debris, local have phenomenon of water gushing in the tunnel construction. This power plant is developed Jian jiang group mountain to tongji field range of hydropower resources, with low brake water, through the high pressure tunnel diversion of water head diversion try to power stations.
