INTRODUCTION 1.1 Project Profile Tugutang Navigation and Hydropower Complex is a low head project, main functioning as navigation, combined with power generation, compatible with irrigation, water supply and aquaculture. Normal water storage level is 58.0 m, 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 3 parts as the main works, temporary works, and the resettlement works. The main works include structure work and supporting works; the temporary works include diversion work and construction auxiliary work. See detail in Table1.1-1. 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 Ship Lock sluice chamber is 180 m x 23 m x 3.5 m (length x width x 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 Sluice gate is adopted; the bottom plate of sluice gate is adopted with fold line-type practical weir. The Complex Main works still pool is 28m long, dissipate energy by hydraulic jump. Structures 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 capacity of 90,000 kW, 4 bulb type units are installed, and 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 built across the Bridge and road sluice gate and main powerhouse section, the bridge is 552 m long. The site road includes works 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. Supporting Move Main works The flood embankment at left and right bank will be moved, and used as site road as well. works flood-control The auxiliary dam at right bank is the section where the upper lock head connecting the embankment moved flood embankment of right bank, with length of 47m. The auxiliary dam is adopted and the auxiliary with earth dam. dam The right bank slope protection ranges from upper & lower main navigation wall to up & Bank protection downstream anchorage place, with protection length of about 2600 m; The left bank slope work protection ranges at 800m of station upstream and 1000m at downstream. The slope protection is adopted with thick bagged concrete protection, Reynold Gabion protection and 2 sod revetment. It is arranged at the left bank of power station, adopting with type of perpendicular single Fish way side vertical seam, the fish way is 773.7m in length, including 192 pool rooms and 21 lounges at flat bottom. Complex It is arranged at left bank of Xiangjiang River upstream of dam axis, closing to the power Management station. Area Construct Hengnan new water source project at the Leishui River, lay 8km long pipeline till New Water Hengnan 1st Water treatment plant, the pump station is adopted with bank vertical shaft Source Project type. upgrade the navigation mark of newly built kiloton navigation channel in Hengyang City, which is 89km away from Jinweizhou Complex. build one kiloton vertical comprehensive Terminals and Terminal berth at Songbai Port in Changning, build one kiloton vertical break bulk berth at Yunji navigation port in Hengnan. channel Navigation channel dredging work, dredge for 30,000 m3 under the dam, navigation marks including Channel bank mark, place indication mark, ship mark, etc. Diversion in the diversion structures include previous low water cofferdam, first stage full year Diversion works stages cofferdam, power house dry season cofferdam, second stage overflow cofferdam, etc. Construction Sandy stone processing system, concrete production system, construction workshop( steel Auxiliary reinforcement and wood work shop, equipment repairing workshop), construction Enterprises warehouse and others. Temporary construction Arranged on both banks. Temporary camp Projects Construction On site access build 5 on site access roads, with total length of 4700 m. Auxiliary works for Tieshi and Pengci, exploit from rubble quarry; borrow area is no required for the Borrow area and Complex .prioritize the excavated sandy pebble from main works for sandy gravel quarry aggregate, the insufficient ones could be exploited from sandy gravel quarry at Luoshazhou, Yuezhou,Xipizhou, and Zhengshi. Waste disposal Waste disposal from left bank is used as backfill for permanent land occupation and rising of area reservoir area; the waste disposal area at the right bank is gully type disposal area. Resettlement The resident Production The production resettlement residents at reservoir area are 1233, cultivated land adjustment Work relocation resettlement in and between the villages are 68.8 hm2; The production resettlement residents at dam 3 area 541, cultivated land adjustment in the village is36.39 hm2. No resident relocation at the reservoir area, the dam area needs to relocate 133 household Relocation of 557 people. Backward relocation and scattering in the village. The farmland surface elevation for raising protection is adopted
