Refuse landfill bottom impermeable layer leakage remedying and repairing method
The method comprises the steps that an anti-seepage curtain body extends downwards along the periphery of a defect area of the refuse landfill, and a horizontal anti-seepage layer extends inwards from the lower portion of the anti-seepage curtain body to be constructed; the method comprises the following steps: determining an area needing defect repair in the early stage of an old or built refuse landfill; anti-erosion cement-based slurry and silica sol slurry are controllably injected into the lower area of the original impervious layer of the defect repair area by adopting a sleeve floral tube pressure grouting method, a new composite impervious body is constructed, a new impervious or blocking layer of the defect area of the refuse landfill is formed, diffusion of pollutants is blocked, and the influence on the environment is reduced or avoided; the newly constructed anti-seepage body is composed of an anti-seepage curtain body and a horizontal anti-seepage layer, the anti-seepage curtain body and the horizontal anti-seepage layer are a complete blocking anti-seepage body and are closely integrated with a complete anti-seepage layer originally completed in a refuse landfill, and blocking and repairing of a defect leakage area are achieved.
本发明公开了一种垃圾填埋场底部防渗层渗漏补救修复方法包括，沿垃圾填埋场缺陷区周边向下延伸构建防渗帷幕体，并在防渗帷幕体下部向内侧延伸构建水平防渗层；本发明在老旧或已建垃圾填埋场前期确定需要缺陷修复的区域；在缺陷修复区域原防渗层的下部区域采用套花管压力注浆法，控制性注入抗侵蚀水泥基浆液和硅溶胶浆液，构建新的复合防渗体，形成垃圾填埋场缺陷区新的防渗或阻隔层，阻断污染物的扩散，减少或避免对环境的影响；新构建的防渗体由防渗帷幕体和水平防渗层组成，两者为一个完整的阻隔防渗体，与垃圾填埋场原来完成的完整的防渗层紧密融合为一体，实现对缺陷渗漏区的封堵和修复。
