The intake of the saddle dam is loc

The intake of the saddle dam is located on the L/B of the riverbed, which is arranged in proximity of the left side of the desilting gate. The power intake comprises the trash rack gate section, the transitional section and the intake gate, the top platform is at El.321.00m. the bottom slab trash rack gate section is El. 318.00m, which is higher than the bottom slab of the desilting gate by 3.0m. After the trash rack gate is a horn-mouth shaped transitional section, the intake gate is an open gate is an open with flat bottom slab, the bottom slab is at El. 317.00m and the opening dimension is 4.5X4.2m (WXH).
The headrace channel includes 1# headrace channel and 2# headrace channel. The full length of 1# headrace channel is 2,669.646m, while that of 2# headrace channel is 1,756.719m, it is to adopt the bottom slope of i=1:2,000 adopting trapezoidal section.
The full length of the forebay is 55.0m in which the length of the transitional section is 22.0m, the length of the forebay section is 33.0m, the bottom slab is to be adopted C20 reinforced concrete lining, while the side wall is to be adopted gravity-type retaining wall. The right side of the forebay is arranged with desilting gate. The end of forebay is at El. 318.522m, the highest surge level is at El. 319.590m, and the lowest operating level is at El. 316.772m.
The penstock is to be adopted the penstock type, according to the location of the ground powerhouse as well as azimuth of longitudinal axis of powerhouse the penstock is to be adopted the combined means of water supply with one main pipe bifurcated into a –shaped four branch pipes and supply water to the four units in the powerhouse . the length of the main pipe is 993.670m, the ID of which is 3.2m, to be totally arranged with 9 anchorage blocks and 77 buttresses. The turning radius of the penstock is taken as 12m, and the entire line is to be adopted 345B steel plate.
1.6.8 Complex layout of Powerhouse Area
The complex of the powerhouse area mainly includes the main powerhouse, the auxiliary powerhouse, the tailrace channel, the step-up substation and powerhouse access road, etc.
The powerhouse is of ground type and the generator hall and the erection bay are arranged as a straight line vertical to Houay Por Gully. The eraction bay is located on the side far away from the river channel, and it is to arrange a 2cm expansion joint between the generator hall and the erection bay. The length width and height (from foundation plane to the column crest) of the generator hall are 50.32m, 14.5m and 10.71m respectively. Installed in the powerhouse are 4 horizontal Francis turbine units, including 2 units with an installed capacity of 5.0MW each and 2 units with an installed capacity of 2.5MW each, it is to arrange a 2cm setting joint between the four units in the generator hall, and the units are installed at El.253.85m. The side of generator hall close to the river channels is arranged with turbine oil depot, oil treatment chamber air compressor chamber, the length width and height of which are 7.14m, 14.5m and 4.20m respectively ( from foundation plane to the column top). The auxiliary powerhouse is 38.64X8.88m (Lxw), theheight is 4.20m, the powerhouse access road is to enter the powerhouse area from the side close to the river channel, and the road width in the powerhouse is 5.0m. The rear side of the auxiliary powerhouse is in proximity of the step-up substation. The dimension of step-up substation is 47.50x28.00m (L x W), and width of the access roads in the step-up substation is 4.0m. The tailrace is to be arranged with forward outflow, the open tailrace channel is connected with the main river channel, which feeds into Xeset River via a tailrace channel with a length more than 1,800m. The turnaround is located on the outer side of erection bay, which connects with powerhouse access road. Since the powerhouse are ais topographically flat, the slope height in the power area are generally between 1-3m, all the slopes should be protected with grouted rubble with thinness of 30cm and gradient of 1:1, and it is to arrange drainage ditches at the bottom of the protection slope.
