Abstract

The utility model provides an anti-blocking type rain water leading out pool of a refuse landfill, belongs to the technical field of refuse disposal engineering of environmental engineering, and mainly aims at the problem that rain water is difficult to lead out for the conventional refuse landfill. The technical scheme of the utility model is that the anti-blocking type rain water leading out pool of the refuse landfill comprises a water blocking and filtering area and a drainage area, wherein the water blocking and filtering area comprises a filtering basin, permeable pebbles arranged in the filtering basin, a grid arranged at the upper parts of the permeable pebbles, and a rain water drain pipe with one side embedded at the lower parts of the permeable pebbles; the drainage area comprises a clear water area, a settling area arranged below the clear water area, a sloping plate arranged in the settling area, and a clear water drain pipe with one side mounted in the clear water area; the other side of the rain water drain pipe extends into the clear water area; and a plurality of water penetrating holes are formed in the rain water drain pipe on one side of the permeable pebbles. The anti-blocking type rain water leading out pool has the advantages of concise integral structure, convenience in construction, and easiness in cleaning and maintenance.

Description

A kind of refuse landfill block-resistant type rainwater is derived the pond

Technical field

The utility model relates to a kind of block-resistant type rainwater of refuse landfill derives the pond, belongs to Environmental Engineering refuse treatment engineering technical field.

Background technology

Refuse landfill is the important environmental protection facility that is widely used in various places, and positive role is being brought into play in garbage disposal, but the sewage of itself, Water in Rainwater Drainage go wrong and has a lot of technological difficulties.

For refuse landfill, the dirty shunting of rain separates extremely important with sewage rainwater clean in the field.If the clean rainwater of bottom, reservoir area can be discharged rapidly, avoid its pollution that is subject to rubbish, just can reduce in a large number the output of percolate in landfill yard, alleviate the pressure that landfill yard is disposed of sewage.But, there are a large amount of foreign material due in the refuse landfill reservoir area, disturb unavoidably the rainwater-collecting work of bottom, reservoir area, therefore, how to prevent that the blockage problem when rainwater is derived from just seeming extremely important.

Summary of the invention

The utility model is derived hard problem mainly for existing refuse landfill rainwater, provides a kind of refuse landfill block-resistant type rainwater of easy derivation refuse landfill rainwater to derive the pond.

The technical scheme that the utility model is taked for achieving the above object is:

A kind of refuse landfill block-resistant type rainwater is derived the pond, filtering area and catchment form by blocking water, wherein: the described filtering area that blocks water by filtering ponds, be located at permeable cobble in filtering ponds, be located at the storm drain that the graticule mesh on permeable cobble top and a side be embedded in permeable cobble bottom and form, described catchment by clear water zone, be located at the clear water zone below the settling zone, be located at the clear water discharge pipe that swash plate, a side in the settling zone be arranged in clear water zone and form; The opposite side of described storm drain extends in clear water zone, and storm drain is positioned on a side of permeable cobble and offers some permeable holes.

Wherein all be provided with impervious barrier in the bottom of filtering ponds and settling zone.

Be provided with one deck antiseepage wrap film in the contact site of described clear water discharge pipe and clear water zone.

The present invention adopts technique scheme, and 1. whole rainwater is derived the pond and is divided into block water filtering area and two of catchments district, guaranteed bottom the reservoir area foreign material, the body refuse in the rainwater that confluxes can be stopped as much as possible.At the filtering area that blocks water, be mainly that the foreign material of large particle diameter are stopped; In the catchment, be mainly that the body refuse class foreign material of small particle diameter are stopped, and unitary construction is succinct, easy construction is easy to cleaning, is easy to safeguard; 2. the utility model adopts the inverted trapezoidal section to construct the pond body, and pool wall that need not be vertical, and the natural soils at the bottom of so just can utilizing excavate to construct the pond body, an impervious barrier HDPE film at the bottom of adding, an antiseepage requirement at the bottom of can satisfying avoids using Reinforced Concrete Structure, reduces cost; 3. at the filtering area that blocks water, adopting the permeable cobble of geotechnological graticule mesh parcel as filtering material, make the platform that blocks water play simultaneously the effect of filtering, is a kind of novel stage body structure.Be common cobble due to what adopt, saved construction cost than filtering materials such as adopting plastics; 4. at heavy mud layer position, swash plate is set, plays the effect of accelerating precipitation.
