技术领域Technical Field
本发明涉及一种固废基高含水率软土固化剂与固化装置，属于淤泥固化处理技术领域。The invention relates to a solid waste-based high-water content soft soil curing agent and a curing device, belonging to the technical field of sludge curing treatment.
背景技术Background technique
我国沿海地区存在着大量高含水率淤泥质土,包括天然沉积软土以及人工吹填土，都需经过加固处理才能用于工程建设。目前国内外对淤泥进行固化选取的材料是水泥，生产水泥会排出大量的二氧化碳，因此需要研发一种可部分替代水泥的胶凝材料。我国基础建设飞速发展，消耗大量的建材原料，同时也会产生建筑固废、工业固废以及衍生的生物质固体废弃物等大宗固废。建筑垃圾，直接扔至垃圾填埋场占用大量空间，但是将建筑垃圾磨细之后会产生胶凝性，可以减缓掉里面含有的水分，使得整个体系很规整，并且将它制成一块一块分开的，具有较好的操作性。工业固废，具有潜在的活性，将其用于固化剂存在更大的优势。生物质固废，火山灰质的成分较多，在用作土壤固化剂时具有许多优势。同时纤维材料可以有效的增强固化土的力学性能。高分子材料提升整体材料的力学性能。利用他们的性质和这些固废进行再利用，生产出固化剂。而现有的固化剂处理系统，需要人为测定淤泥中的成分，进一步的判断处理固化剂的用量，其过程繁琐复杂，因此需要研发一种固废基高含水率软土固化剂及其处理系统。There are a lot of high-water content silty soils in my country's coastal areas, including natural sedimentary soft soil and artificial blown fill soil, which need to be reinforced before they can be used for engineering construction. At present, cement is the material selected for silt solidification at home and abroad. The production of cement will emit a large amount of carbon dioxide, so it is necessary to develop a cementitious material that can partially replace cement. my country's infrastructure is developing rapidly, consuming a large amount of building materials and raw materials, and also generating large amounts of solid waste such as construction solid waste, industrial solid waste and derived biomass solid waste. Construction waste, thrown directly into the landfill, takes up a lot of space, but after grinding the construction waste, it will produce gelling properties, which can slow down the water contained in it, making the whole system very regular, and making it separate piece by piece, with better operability. Industrial solid waste has potential activity, and there are greater advantages in using it as a curing agent. Biomass solid waste has a large amount of volcanic ash components, which has many advantages when used as a soil curing agent. At the same time, fiber materials can effectively enhance the mechanical properties of the solidified soil. Polymer materials improve the mechanical properties of the overall material. Use their properties and these solid wastes for reuse to produce curing agents. The existing curing agent treatment system requires manual measurement of the components in the sludge and further judgment of the amount of curing agent to be used. The process is cumbersome and complicated. Therefore, it is necessary to develop a solid waste-based high-moisture content soft soil curing agent and its treatment system.
