Flood Discharge Gate in Yangzhuang Flood Detention Area Located on the main stream of Xiaoxianhe, Yangzhuang Township, 22km west of Xiping County, Henan Province, it is a 4-well 10 × 7m open chest wall gate with plane floor and maximum discharge of 1500m 3 / S. And the overall consolidation of the floor, each two holes slit was two mountain-shaped structure, while the piers are semi-gravity retaining wall, the upper and lower wing wall is empty box-type and buttress retaining wall. Floodgate structural design (ie, requirements) foundation bearing capacity, light silty loam not less than 180kpa, soft soil is not less than 100kpa. According to geological drilling data, most of Zhaji main stratum belongs to
