Method for recycling softened bottom mud of hard revetment
The invention discloses a hard revetment softened bottom mud recycling method which comprises the following steps: bottom mud excavation: constructing a temporary cofferdam at a river channel construction section, draining river channel water, and carrying out dry excavation; fully mixing the bottom mud: stirring and mixing the flow mud and the sludge in situ through an excavator; stirring the bottom mud: adding Portland cement, an additive containing inorganic components, limestone soil, microorganisms and an oxidizing agent into the bottom mud, and fully stirring; a formwork is built at the hard revetment, and recycled bottom mud is conveyed to the formwork through a pump to be poured, vibrated, leveled, maintained and disassembled; after the bottom mud is formed, the aquatic plants are planted on the bottom mud, and the aquatic plants comprise submerged plants, emergent aquatic plants and hygrophytes. The method has the advantages that the aesthetics of the river channel is improved, the harmony of people and water is promoted, and the endogenous pollution of the river channel is reduced, meanwhile, the goal of a closed-loop circulating river channel ecological system is achieved, and the defects of modern river channel ecological design are overcome.
本发明公开了一种硬质驳岸软化的底泥资源化的方法，该方法包括以下步骤：底泥开挖：在河道施工段构筑临时围堰，将河道水排干后进行干挖；底泥充分混合：通过挖掘机将流泥、淤泥在原位进行搅拌混合；底泥搅拌：在底泥中添加硅酸盐水泥、无机成分的添加剂、石灰土、微生物、氧化剂进行充分搅拌；硬质驳岸改造：在硬质驳岸处搭建模板，将资源化的底泥通过泵输送到模板进行浇筑、振捣、整平、养护、拆模；水生植物种植：当底泥成型后，在上面种植水生植物，水生植物包括沉水植物、挺水植物和湿生植物。本发明具有提高河道的美观性，促进人水和谐，又削减了河道内源污染的优点，同时实现了闭环循环的河道生态系统目标，弥补了现代河道生态设计的不足。
