钟山渡槽为双曲拱支承结构 ,槽身为钢筋混凝土 ,底板为拼装式微弯板。渡槽于 1975年开工 ,1978年上半年开始通水运行。由于运行时间较长 ,工程老化严重 ,槽身存在不同程度的纵、横向裂缝。 2 0 0 1年经过多方案的比较、选择化学防水材料SR塑性止水材料、HK - 96 8环氧增厚涂料、 90 3聚合物水泥砂浆防水胶和HK -GFJ钢纤维硅粉混凝土对渡槽进行了全面的防渗补强处理 ,取得了良好的效果
Zhongshan double-arch aqueduct arch support structure, the body of reinforced concrete, the floor is assembled micro-bending plate. Aqueducts started in 1975, the first half of 1978 began running water. As a result of a long running time, serious engineering aging, there are varying degrees of vertical and horizontal groove cracks. In comparison with many schemes in 2001, SR plastic water-stop material, HK-968 epoxy thickening coating, 903 polymer cement mortar waterproofing rubber and HK-GFJ steel fiber silica fume concrete were chosen as the raw materials for aqueduct A comprehensive anti-seepage enhancement treatment, and achieved good results
