二干排属海河流域卫河水系,全长26km,流域面积204km2。由于河道防洪标准较低,主河槽淤积严重,对武陟县城区及下游7个乡镇的防洪安全构成了严重威胁。针对二干排河道现状,根据防洪要求,确定河道规划治理防洪标准20年一遇,除涝标准5年一遇。依据防洪及除涝标准,经过水文计算,确定采取堤防填筑、主河槽疏浚、护岸衬砌、涵闸建筑物及防汛道路等相应工程措施。
Second dry row is the Haihe River Wei River, a total length of 26km, basin area of 204km2. Due to the low standard of river flood control and the serious siltation of the main channel, it poses a serious threat to flood control safety in the urban areas and downstream seven townships in Wu County. According to the current situation of the second Ganpai River, according to the requirements of flood control, the flood control standard of the watercourse planning and treatment shall be determined once in 20 years, and the standard of waterlogging shall be once every 5 years. According to the standards of flood control and waterlogging control, after hydrological calculation, the corresponding engineering measures such as embankment filling, main channel dredging, revetment lining, culvert gates and flood control roads are determined.
