Sludge regenerated mixture and backfill construction method
The invention belongs to the technical field of building construction, and particularly relates to a sludge regeneration mixture and a backfill construction method.The sludge regeneration mixture comprises mucky soil, cement and a modifier, and the modifier comprises waste concrete and alkaline dros.The sludge backfill construction method comprises the steps that dredging equipment is used for digging out the mucky soil from a river channel or a side ditch; the muddy soil is placed on the shore, large solid impurities are separated from the muddy soil, then the muddy soil is placed outdoors for one month and filtered, cement, waste concrete and alkaline residues are added and stirred evenly, and the muddy soil is backfilled into a corresponding river channel or a side ditch through sludge backfilling; compared with the prior art, the method has the advantages and positive effects that the modification effect equivalent to that of lime and aggregate which are used as traditional modifiers can be obtained by using the alkaline residues and the waste concrete which are used as wastes as modifiers, combination can be generated through chemical excitation, physical combination can also be generated, and meanwhile, heavy metals and organic matters can be sealed and stored.
本发明属于建筑施工技术领域，具体涉及一种淤泥再生混合料及回填施工方法，淤泥再生混合料包括淤泥质土、水泥和改性剂，改性剂包括废砼和碱渣，一种淤泥回填施工方法，包括使用清淤设备将淤泥质土从河道或者边沟中挖出，放置于岸上，大型固体杂物与淤泥质土分离，而后将淤泥质土露天放置一个月，进行过滤，而后加入水泥、废砼和碱渣，搅拌均匀，淤泥回填将淤泥质土回填入对应河道或者边沟；与现有技术相比，本发明的优点和积极效果在于：利用作为废弃物的碱渣和废混凝土作为改性剂能得到与利用传统改性剂石灰和集料相当的改性效果，既能经过化学激发产生结合，又产生物理结合，同时还可以把重金属、有机物封存。
