Subgrade filling method by carbonization and solidification of industrial waste residues and drilling residue soil
The invention discloses an industrial waste residue carbonization and solidification drilling residue soil roadbed filling method. The method comprises the steps that the proportion of drilling residue soil, industrial waste residues and an alkali activator and the optimal moisture content of roadbed filler under different proportions are determined; the drilling residue soil, the industrial waste residues, the alkali activator and the water are fully mixed and stirred according to the proportion, and then subgrade layered filling and rolling are conducted; drilling holes in the filled roadbed, arranging gas injection pipelines in the holes, and injecting compressed CO2 gas into a roadbed filling body through the gas injection pipelines for carbonization; and after CO2 gas injection is finished, water vapor is injected into the roadbed filling body through a gas injection pipeline, and then the roadbed filling body is covered with a film for sealed maintenance. The waste drilling residue soil and the industrial waste residues are used as main filling materials, two curing effects of alkali excitation and carbonization are combined, resource reutilization of the two kinds of waste is achieved, and the problems that solid waste is stacked and occupies land, and the treatment cost is high are solved; meanwhile, mineral carbon sequestration is achieved through the carbonization effect, and engineering carbon sink is reduced.
本发明公开了一种工业废渣碳化固化钻渣土路基填筑方法，包括确定钻渣土、工业废渣、碱激发剂配比及不同配比下的路基填料最佳含水率；按配比将钻渣土、工业废渣、碱激发剂、水充分混合搅拌后进行路基分层填筑、碾压；对填筑后的路基钻孔，孔内布设注气管道，通过注气管道向路基填筑体注入压缩CO2气体进行碳化；CO2注气结束后，通过注气管道向路基填筑体注入水蒸气，然后对路基填筑体覆膜密封养护。本发明以废弃钻渣土、工业废渣为主要填筑材料，结合碱激发与碳化两种固化作用，实现两类废弃物的资源再利用，缓解固体废弃物堆积占地、处理成本高的问题；同时，碳化作用实现了矿物碳封存，降低工程“碳汇”。
