1工程概况淮干芦集圩区位于淮滨县城西10～25km的芦集乡和邓湾乡境内,其南堤即淮河左堤,面临闾河,东面隔堤与乌龙港相临,北部和西部地势稍高与岗地接壤,为半封闭式圩区。芦集圩区堤防总长25．6km。由于于堤段本身属沙堤,透水性较强,且堤基存在深塘、渗径短,高水位时渗漏严重。勘探资料表明,50K以下堤身渗透系数为A×10~(-2)～10~(-4)cm/s,一般为A×10~(-3)cm/s,不能满足渗透稳定要求,经批准进行劈裂灌浆处理。
1 Project Overview Huaiqian Luji dike area is located in Luji Township and Dengwan Township, 10 ~ 25km west of Huai Bin County. The South Embankment is the left bank of the Huaihe River and faces Luhe River. The east embankment is adjacent to Oolong Port, The northern and western terrain slightly higher and Kongdi bordering, semi-enclosed polder. Luji dike dike total length of 25.6km. Due to the dike itself is a sandy dike, strong permeability, and dike foundation deep ponds, seepage short, high water level when the leak. The exploration data show that the permeability coefficient of bank below 50K is A × 10 -2 to 10 -4 cm / s, generally A × 10 -3 cm / s, which can not meet the requirements of seepage stability. Approved for splitting grouting.
