Normal water storage level is 58.0m, corresponding reservoir capacity is 197 million m3 and the channelized waterway is 50 km, designed navigation capacity for ship lock is 1000t, the installed capacity is 90 MW. Tugutang Navigation and Hydropower Complex mainly comprise such three parts as the main works, temporary works, and resettlement works. The main works include structure work and supporting works; the temporary works include diversion work and construction auxiliary work, and resettlement works include residents’ relocation, reservoir area protection and restoration of special facilities. See detail in Table1.1-1. Table 1.1 - 1 Works of Tugutang Navigation and Hydropower Complex Project Works Component Ship locks brake, anchoring section, alignment section, navigation section, and section of lock head and sluice chamber, the total length is 1300m along the axis direction. the sluice chamber is 180 m Ship Lock ×23 m ×3.5 m (length ×width × water depth of gate sill). The ship will enter the chamber in curve way, and come out in straight way. The approach channel is 55 m wide and 530 m long. Sluice Gate has 17 orifices, the orifice width is 20 m, and pier width is 3.0m. Steel radial gate is adopted; Sluice gate the bottom plate of sluice gate is adopted with fold Main Complex line-type practical weir. The stilling basin is 28m works Structures long, dissipate energy by hydraulic jump. The main structures in the plant area consist of main powerhouse, erection bay, downstream auxiliary powerhouse, central control building, plant upstream barrage dam, downstream flood wall, upstream entrance channel, tailwater channel, access traffic, Power Station outdoor GIS and main transformer yard, underground cable access and outgoing platform, outdoor gantry crane installation and overhaul platform, and retaining wall of gantry crane platform. The power station has total installed Project Works Component capacity of 90,000 kW, 4 bulb type units are installed,, each capacity is 22,500 kW. The pre-stress concrete will be built at 530m downstream of dam axis; carry out cantilever cast in construction of continuous rigid frame box bridges, the bridge is 144.72 m in total. The bracket is used as the foundation at pier upstream, service bridge is Bridge and road built across the sluice gate and main powerhouse works section, the bridge is 552 m long. The site road includes branches at both left and right bank, and their upstream and downstream road connects with original flood embankment, respectively, the road subgrade is 7.5M wide, with length of 1.8 Km and 3.5 Km, respectively. The flood embankment at left and right bank will be Moving flood moved, and used as site road as well. The auxiliary control dam at right bank is the section where the upper lock embankment and head connecting the moved flood embankment of the auxiliary dam right bank, with length of 47m. The auxiliary dam is adopted with earth dam. The right bank slope protection ranges from upper & Supporting lower main navigation wall to up & downstream Works anchorage place, with protection length of about Bank protection 2600 m; The left bank slope protection ranges at work 800m of station upstream and 1000m at Main downstream. The slope protection is adopted with works thick bagged concrete protection, Reynold Gabion protection and sod revetment. It is arranged at the left bank of power station, adopting with type of perpendicular single side Fish way vertical seam, the fish way is 773.7m in length, including 192 pool rooms and 21 lounges at flat bottom. It is arranged at left bank of Xiangjiang River Complex upstream of dam axis, closing to the power station. Administration Area The Complex management area has area of 4.0hm2, with construction area of 7500m 2. Construct Hengnan new water source project at the New Water Source Leishui River, lay 8km long pipeline till Hengnan 1st Works Water treatment plant, the pump station is adopted with bank vertical shaft type. Upgrade the navigation mark of newly built kiloton navigation channel in Hengyang City, which is 89km Terminal away from Jinweizhou Complex. Build one kiloton Terminal and and vertical comprehensive berth at Songbai Port in Navigation Changning, build one kiloton vertical break bulk Channel berth at Yunji port in Hengnan. Works channel dredging work, dredge for 30,000 m3 Navigation under the dam, navigation marks including bank Channel mark, place indication mark, ship mark, etc. Table 1.1.-1 (Continued) Project Works Component The diversion structures include previous low water cofferdam, first stage full year Diversion Diversion in cofferdam, power house dry season works stages cofferdam, second stage overflow cofferdam, etc. Sandy stone processing system, concrete Construction production system, construction workshop Auxiliary (steel reinforcement and wood work shop, Enterprises equipment repairing workshop), construction warehouse and others. Temporary construction Arranged on both banks. camp Temporary On site build 5 on site access roads, with total Works access length of 4700 m. for Tieshi and Pengci, exploit from rubble Construction quarry; borrow area is no required for the Auxiliary works Complex .prioritize the excavated sandy Borrow area pebble from main works for sandy gravel and quarry aggregate, the insufficient ones could be exploited from sandy gravel quarry at Luoshazhou, yuezhou,Xipizhou, and Zhengshi. waste disposal from left bank is used as backfill for permanent land occupation and Waste raising of reservoir area; the waste disposal area disposal area at the right bank is gully type disposal area. The production resettlement residents at reservoir area are 1233, cultivated land Production adjustment in and between the villages is resettlement 68.8 hm2; The production resettlement Resident residents at dam area 541, cultivated land relocation adjustment in the village is36.39 hm2. No resident relocation at he reservoir area, the dam area need to relocate 133 Relocation household of 557 people. backward relocation and scattering
