River channel dredging construction method
The invention relates to the technical field of river channel treatment, in particular to a river channel dredging construction method. The method comprises the following steps of a, investigating a to-be-dredged river channel, and segmenting the to-be-dredged river channel; b, building a temporary cofferdam for a to-be-dredged river channel section according to the condition of the to-be-dredged river channel section; only building a temporary cofferdam for half of the to-be-dredged river channel section, and dredging a riverbed in the temporary cofferdam; after the river channel in the temporary cofferdam is dredged, removing the temporary cofferdam, then building a temporary cofferdam for the other half of the river channel section, and dredging a riverbed in the temporary cofferdam; c, repeating step b on a downstream river channel; d, precipitating and flocculating cleaned muddy water to obtain sludge; e, purifying and dehydrating the sludge, and conducting backfilling on the purified and dehydrated sludge. The method has the advantages that the influence of dredging construction on rivers is small, and water level changes of the upstream river and the downstream river are not large.
本申请涉及河道治理的技术领域，尤其是一种河道清淤施工方法，包括以下步骤：a.勘察拟清淤河道，对拟清淤河道进行分段；b.根据拟清淤河道段的情况对拟清淤河道段搭建临时围堰；在搭建临时围堰时只对拟清淤河道的一半搭建临时围堰，对临时围堰内部的河床进行清淤工作；当临时围堰内部的河道清淤完成之后，拆除临时围堰，之后对同段河道的另一半搭建临时围堰，并开始对临时围堰内部的河床开始清淤施工；c.对下游河道重复步骤b；d.对清理出来的泥水进行沉淀和絮凝得到淤泥；e.对淤泥进行净化和脱水，并将净化和脱水之后的淤泥回填处理。本申请具有清淤施工对河流的影响较小，上流河流和下游河流的水位变化不大，清淤施工对河流的影响较小的效果。
