Description
Technical field
The utility model particularly relates to a kind of leakage preventing structure in geotextile tube bag dehydration place about a kind of leakage preventing structure.
Background technology
Due to history, the numerous household refuse landfill sites of China once received municipal sludge, industrial sludge etc., in life
The big sludge lagoon of seriously polluted, potential safety hazard has been gone into refuse landfill living.In sludge lagoon governance process, in-situ solidifying skill
Art turns into an important solution technology.But the sludge of the muddy water binder course for moisture content more than 95%, in-situ solidifying technology
There is difficulty, it is necessary to take resolidification after dehydration to process.Sludge geotextile tube bag dehydration technique can solve the dehydration of muddy water binder course and ask
Topic.In sludge lagoon in-situ solidifying governance process, it is necessary to for geotextile tube bag builds a base when using geotextile tube bag dehydration technique
Plinth is stable, prevent filter liquor seepage and effectively collect the safe and environment-friendly place of filter liquor.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of leakage preventing structure in geotextile tube bag dehydration place,
In geotextile tube bag sludge dehydration process, deviate from sewage can be controlled to be able to effectively collect, prevent sewage pollution soil
And underground water.
To reach above-mentioned purpose, the utility model provides a kind of leakage preventing structure in geotextile tube bag dehydration place, including under
It is supreme set gradually including basal layer, film lower protective layer, impervious barrier, film up-protective layer, water lead layer；The basal layer is soil
Layer；The impervious barrier is density polyethylene film with high layer；The film lower protective layer and film up-protective layer are filament nonwoven geotextiles
Layer；The water lead layer is to include soil engineering composite drainage network and rubble drainage blanket, and wherein soil engineering composite drainage network is arranged in rubble
The lower section of water layer.
The compactness of the soil layer is more than or equal to 93%.
The grammes per square metre of the filament nonwoven geotechnique layer of cloth is more than or equal to 400g/m2。
The thickness of the density polyethylene film with high impervious barrier is more than or equal to 1.0mm.
The thickness of the soil engineering composite drainage network is more than or equal to 6.0mm.
The thickness requirement of the rubble drainage blanket is not less than 200mm, wherein the ballast grain sizes for including are 20mm~60mm, and
