1. a kind of construction method of microorganism solidification cinder from refuse incineration porous pavement is characterised by that this method step is as follows:

  • A. unsized cinder from refuse incineration is paved on the roadbed (1) of leveling and grinding compacting, compacted depth 20cm,It is 95% to control compactness, as underlayment (2);

    B. one layer of geotextiles are laid as filter layer (3) in underlayment (2) upper surface;

    C. take that cinder from refuse incineration of the particle diameter less than 10mm paves on filter layer (3) after screening and grinding compacting, compacting are thickSpend for 20cm, it is 95% to control compactness, as basic unit (4);

    D. it is 1 times of basic unit (4) pore volume, the CaCl that concentration is 0.02mol/L first uniformly to spray volume to basic unit (4) upper surface2Solution, after fully penetrating into, then volume is sprayed for 1.5 times of basic unit (4) pore volume, concentration OD600=1.2 bacterium solution, stand2h;

    E. to basic unit (4) upper surface uniformly spray volume be 1.5 times of basic unit (4) pore volume, concentration be 0.8mol/L~1.2mol/L consolidating fluid, after fully penetrating into, stand 12h;

    F. step e is repeated 4~6 times;

    G. particle diameter is less than 5mm cinder from refuse incineration and middle sand mix after taking screening, paves on basic unit (4) and rolls closeReal, compacted depth is 10cm~20cm, and it is 97% to control compactness, as surface layer (5);

    H. it is 1 times of surface layer (5) pore volume, the CaCl that concentration is 0.02mol/L first uniformly to spray volume to surface layer (5) upper surface2Solution, after fully penetrating into, then volume is sprayed for 1.3~1.5 times of surface layer (5) pore volume, concentration OD600=1.2 bacteriumLiquid, stand 2h;

    I. to surface layer (5) upper surface uniformly spray volume be 1.3~1.5 times of surface layer (5) pore volume, concentration be 0.8mol/L~1.2mol/L consolidating fluid, after fully penetrating into, stand 12h;

    J. i step 4~6 time are repeated, complete construction.
