摘　　要：卓家庄沟下游沟道被挤压侵占,已埋设的涵管规模较小,导致排水不畅,造成洪水时,倒虹吸进出口水位壅高,存在洪水入总干渠的隐患。本设计采用倒虹吸进出口设挡水墙和易水灌渠下涵管扩建方案,保证了总干渠的安全。The channel downstream of Zhuojiazhuanggou has been occupied,and the diameter of the drain line is too small to drain water. The river level of the entrance of the inverted siphon will be rised with flood water,and it will be dangerous when the flood flow into the main channel of South Water to North.In order to protect the main channel,the breakwater wall will be built outside the entrance of the inverted siphon,and the drain line will be expanded.
