Construction process for applying dredged sediment to construction of coastal ecological zone
The invention relates to a construction process for applying dredged sediment to construction of a coastal ecological zone. The process comprises the following steps: (1) arranging steel sheet piles in a river and lake ecological zone of a to form a strip-shaped closed cofferdam; (2) implementing an environment-friendly dredging and hydraulic reclamation construction process in the river and lake, and conveying dredged sediment into the cofferdam; (3) treating tail water overflowing from the water outlet of the cofferdam; (4) after the dredged sediment in the steel sheet pile cofferdam is subjected to static settlement, carrying out electro-osmosis combined vacuum pre-pressing rapid dehydration; (5) according to the gradient of the natural bank slope and the ecological restoration requirement, carrying out terrain consolidation; (6) planting and recycling emergent aquatic plants according to construction seasons to realize ecological treatment of the bottom mud; and (7) after ecological restoration is completed, dismantling the steel sheet pile cofferdam, and form a natural ecological wetland. According to the invention, application of dredged sediment in the aspect of coastal ecological zone construction is achieved, endogenous pollution is eliminated, volume reduction and weight reduction treatment is conducted on the sediment, cementation and storage of nutrient substances are achieved, and ecological restoration is achieved through emergent aquatic plants.
本发明涉及一种将疏浚底泥用于滨岸生态带建设的施工工艺。包括以下步骤：(1)在河湖滨岸生态带打设钢板桩形成条带状封闭围堰；(2)在河湖内实施环保疏浚吹填施工工艺，将疏浚底泥输送至围堰内；(3)对围堰排水口溢流出的尾水进行处理；(4)钢板桩围堰内的疏浚底泥静置沉淀后，进行电渗联合真空预压快速脱水；(5)根据自然岸坡坡度及生态恢复要求，进行地形整理；(6)根据施工季节种植并回收挺水植物，实现对底泥的生态处置；(7)生态修复完成后，拆除钢板桩围堰，形成自然生态湿地。本发明实现了疏浚底泥在滨岸生态带建设方面的应用，消除内源污染并对底泥减容减量处理，实现营养物质的胶结封存并采用挺水植物实现生态恢复。
