Description
Technical field
The present invention relates to garbage loading embeading field, in particular to a kind of refuse landfill sealing exhaust systems.
Background technique
When refuse landfill operation to designed elevation or place where the garage is piled up is no longer stored rubbish and stopped using, need to seal
Field processing.Closure of landfill site engineering includes surface water diameter flow control, draining, antiseepage, leachate collection processing, landfill gas collection
Processing, heap body is stable, vegetation pattern selects and the contents such as covering.The purpose of closing is reduced by the build on landfill yard surface
It corrodes and drains to greatest extent, control the pollution of landfill leachate and refuse landfill gas, and play the role of ecological recovery.
Existing refuse landfill sealing exhaust uses gabion mostly, and gabion is spaced apart inside rubbish, but gabion is arranged
Gas has the following problems, since gabion is set within rubbish, setting is inconvenient.Simultaneously because rubbish settles, gabion is also resulted in
Pullling with rubbish movement causes gabion to damage, and since garbage degradation can generate percolate, percolate is mixed into viscous exception with dirt
Thick shape sewage easily blocks gabion gas vent, influences exhaust efficiency, easily lead to methane accumulation and cause safety accident.
