针对非正规垃圾填埋场性质复杂、垃圾填埋不均一、污染源埋深大、容易造成地下水污染等特点,基于宾汉姆流体的柱—半球形扩散理论,进行了水平静压注浆防渗技术研究.通过改进注浆工艺、优化注浆流程,修复含水层隔水顶板,封堵污染因子向下迁移通道,保护地下水源.将该技术应用于河南省某非正规垃圾填埋场地下水污染治理,注浆后防渗层渗透系数为1.04×10-6～3.81 ×10-5 cm/s,达到或高于粉质黏土的渗透级别,注浆段视电阻率显著降低,取得良好防渗效果,据此探索出一种阻隔高风险污染源与其下伏含水层的工程控制模式.
Study on anti-seepage technology for informal landfills using the principle of permeability grouting
In response to the complex nature,uneven landfill,deep burial depth of pollution sources,and easy groundwater pollution of informal landfill sites,based on the Column Hemispherical Diffusion Theory of Bingham Fluid,horizontal static pressure grouting anti-seepage technology was studied.By improve the grouting process and optimizing the grouting process,repair the waterproof roof of the aquifer,block the downward migration channel of pollution factors,and protect the groundwater source.The technology was applied to the treatment of groundwater pollution in an informal landfill site in Henan Province.After grouting,the permeability coefficient of the anti-seepage layer was 1.04 × 10-6-3.81 × 10-5 cm/s,which reached or exceeded the permeability level of silty clay.The apparent resistivity of the grouting section was significantly reduced,achieving good anti-seepage effect.Based on this,an engineering control mode was explored to block high-risk pollution sources and their underlying aquifers.
