The inlet of the newly-built passenger building flood discharge tunnel is located at the drainage hole, and the outlet is near the Xujia gate of Feishuiyan River. The design flow rate is 125m3/s (P=10%), with a total length of 1.032km; The Feishuiyan River regulation project starts from Xujiaduimen and ends at the artificial tunnel at Fuliudong in Fengba Village, Pangjiazhai. The total length of the project regulation is 1.418km (centerline). (2) The project is located in Kelou Town, Cengong County, involving Kelou Town, Anshan Village, and Fengba Village, protecting a population of 3120 and 565 acres of farmland. The protection level of the project area is Grade IV. (3) According to the "Flood Control Standards" (GB50201-2014) and the "Classification and Flood Control Standards for Water Resources and Hydropower Engineering" (SL252-2017), the protection level of this project is Grade IV. According to the "Design Code for Embankment Engineering" (GB50286-2013), the "Basic Requirements for the Preparation of Preliminary Design Reports for Small and Medium sized River Treatment Projects in Guizhou Province", and combined with the situation of the protected objects of this project, the protected objects on both sides of the river section are population and farmland. Towns and villages adopt a 10-year flood standard, and farmland adopts a 5-year flood standard (P=20%). (4) The design flood flow rate of the newly built passenger building drainage tunnel is 125m3/s, ranging from 100 to 300m3/s.
