Construction scale

The water area improvement project includes two newly opened mountain ponds with a total area of about 38 mu; The dam crest of Yangjianshan Reservoir is heightened and the back of the dam is widened, the road on the dam crest is reconstructed, the spillway of Yangjianshan Reservoir is reconstructed, the spillway of Shanghengfan Reservoir is reconstructed, and the irrigation canal behind the dam of Yangjianshan Reservoir is reconstructed about 0.4km; The length of river regulation is about 6km, including about 4km for Xiangxi regulation, about 1km for Huangfanxi regulation and about 1km for Yangjianshan intake channel; The connecting channel between Yangjianshan Reservoir and Wangliyuan Reservoir is about 0.8km long, with a water area of about 135 mu, and a new control gate.

Municipal infrastructure works include site leveling works and traffic works; The traffic engineering involves 6 urban roads, 4 bridges, 7 culverts and 1 tunnel. The construction contents include: roads, pipelines, bridges, tunnels, lighting, intelligent transportation, environmental improvement and ancillary works. Among them, the road project is about 300000 m2, the bridge and culvert area is about 30000 m2, and the tunnel project is about 1000 m.

The ecological restoration and environmental improvement project includes two parts: ecological restoration project and environmental improvement project. The ecological restoration project mainly includes about 4hm2 of the front reservoir wetland project, about 20km of the riparian buffer zone project, about 6hm2 of the riparian wetland project, and about 20hm2 of the in-situ water ecological restoration project; The environmental improvement project includes about 70000 m2 of waterfront open space project, about 2 million m2 of greening project, about 150000 m2 of slow-moving system project and corresponding supporting facilities, lighting, water supply and drainage, weak current project, etc.
