Landfill maintenance, restoration method and landfill self-formation, self-healing complex order floor construction method

摘要

The present invention can prevent soil contamination and groundwater contamination by maintaining and restoring the unsanitary landfill site or the landfill site that has been landfilled as a pollution source. In addition, landfills can be constructed and recycled for this purpose.;The process procedure of the landfill maintenance and restoration method of this invention and the buried land self-forming and self-healing composite order layer construction method is as follows.;(1) dividing the landfill site into a predetermined depth to install a landfill gas (LFG) collection pipe and an air inlet pipe, and rapidly stabilize; (2) digging the landfill waste from the excavation zone to sort and transport coarse particles and non-combustible waste; (3) separating the soil and vinyls on the rotating screen; (4) separating the soil and vinyl from the roller screen; (5) separating the vinyls and the non-combustible wastes by wind power at the rear stage; (6) separated sedimentary soil and contaminated soil may be subjected to thermal desorption or biological soil purification process using a bioreactor drum according to the contaminated state; (7) Provide a landfill maintenance and restoration method that includes re-filling or incineration by squeezing or melting the separated vinyls. (8) a geosynthetic transport cleanup step; (9) earth and sand grinding and screening processes; (10) bioreaction and humic acid decomposition removal processes; (11) solidifying agent blending step; (12) water content adjustment and mixing process; 13) plan adjustment process of improved soil transport and reaction order layer; (14) compaction and penetration measurement processes; (15) curing and surface treatment steps; (16) By providing landfill site repair and restoration methods including the process of installing seat sheets and landfill self-forming and self-healing complex order layer construction methods, it is possible to prevent environmental pollution and to recycle landfills usefully.
