Microbial mineralization and carbide slag synergistically reinforced semi-rigid vertical barrier and preparation method thereof
The invention relates to a semi-rigid vertical blocking barrier synergistically reinforced by microbial mineralization and carbide slag and a preparation method thereof, the semi-rigid vertical blocking barrier comprises the following raw material components: calcium bentonite, in-situ soil, urease bacteria excitant and carbide slag, the dry mass of the calcium bentonite accounts for 15.0%-25.0% of the dry mass of the in-situ soil, the dry mass of the urease bacteria excitant accounts for 15.0%-25.0% of the dry mass of the in-situ soil, and the dry mass of the carbide slag accounts the total dry mass of each component in the urease bacterium excitation substance accounts for 2.0%-4.0% of the dry mass of the in-situ soil, and the dry mass of the carbide slag accounts for 3.0%-6.0% of the dry mass of the in-situ soil. The defect that the effect of improving and reinforcing fine-grained soil through a microbial mineralization technology is poor can be overcome, the strength and anti-seepage performance of the blocking barrier material based on the calcium bentonite can be remarkably improved, meanwhile, by-product ammonium ions in the microbial mineralization process are utilized, and the cost and carbon emission of the blocking barrier material are reduced.
本发明涉及一种微生物矿化与电石渣协同强化的半刚性竖向阻隔屏障及其制备方法，其原料成分包括钙基膨润土、原位土、脲酶菌激发物和电石渣，其中，所述钙基膨润土干质量占原位土干质量的15.0％～25.0％，脲酶菌激发物中各组分总干质量占原位土干质量的2.0％～4.0％，电石渣干质量占原位土干质量的3.0％～6.0％。本发明可以解决微生物矿化技术改良加固细粒土效果欠佳的缺陷，能够显著提高基于钙基膨润土的阻隔屏障材料的强度与防渗性能，同时利用了微生物矿化过程中的副产物铵根离子，降低了阻隔屏障材料的成本及碳排放。
