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.
