Decommissioning demolition and connectivity repair method for sedimentation reservoir
The invention discloses a decommissioning demolition and connectivity restoration method for a sedimentation reservoir. The method comprises the following steps that S1, river channel morphological characteristics before dam building and after reservoir forming are obtained; s2, a river bed under the dam is excavated to form a sediment-carrying collecting tank; s3, a reservoir surface water net is grooved for diversion, and holes are drilled in a dam body for drainage; s4, the reservoir area terrain is remodeled into river channel morphological characteristics before dam building; s5, screening the sediment into materials to be used with different forms and particle sizes; s6, the materials to be used are utilized in multiple aspects and multiple areas according to the particle size; and S7, the barrage is locally dismantled, and a dam body water passing culvert is formed. According to the method, a reservoir area sediment partial excavation and dam body partial dismantling mode is determined through historical and current river channel characteristic comparison, the traffic function of the dam body is reserved, meanwhile, connectivity restoration of the barrage and the silt full reservoir is achieved, and the restoration cost and adverse ecological influences are reduced.
一种淤积水库退役拆除和连通性修复方法，包括以下步骤：步骤S1：获取建坝前、成库后的河道形态特征；步骤S2：坝下河床开挖形成携带沉积物收集槽；步骤S3：库表水网挖槽导流，坝体内钻孔排水；步骤S4：库区地形重塑为建坝前河道形态特征；步骤S5：沉积物筛分成形态粒径不同的待用料；步骤S6：待用料按粒径进行多方面多区域利用；步骤S7：拦河坝局部拆除，形成坝体过水涵洞。通过历史、现状河道特征对比来确定库区沉积物部分开挖、坝体部分拆除的方式，在保留了坝体交通功能的同时，实现了拦河坝和淤满水库的连通性修复，降低了修复成本和不利生态影响。
