The recent treatment of the river bank The dredging section of the river is located between Taihang County Weiwan gate and Luyi county Xuanwu gate, with a total length of 39.3km. Depth of work area exploration in the formation of the Quaternary Pleistocene and Holocene alluvium. The Quaternary Upper Pleistocene (Q3) mainly consists of brownish-yellow, light brownish-yellow, low-liquid-limited clays and locally high-liquid-limited clays. In the lower section of Quaternary Holocene (Q4), the geological structure is a double-layer structure of grit sand. The upper part is low-liquid-limit clay, partially-fostered silt sand and low-liquid-tight silt lenses. The lower part is mainly composed of the lower part of silt- Gray-black low liquid limit clay, containing organic matter, central
