Description
Technical field
The present invention relates to urban refuse sanitary landfill laying anchor structures, belong to environmental technology field.
Background technique
With the development of national economy, the raising of the level of urbanization, the yield of domestic waste is in increase sharply.
There are mainly three types of final disposal methods for domestic waste: sanitary landfills, compost and burning.Wherein sanitary landfills is the current world
Upper most common technology of garbage disposal.It is on the basis of scientific addressing, using necessary place protective treatment means and conjunction
The landfill structure of reason, farthest to reduce and eliminate influence of the rubbish to environment, especially to underground water body pollution.In recent years
Come, large MSW landfill is being built in succession in many cities.
In urban health landfill yard, the dirt of underground water is caused to prevent that Leachate site from permeating the ground, it is necessary to setting liner
System.During landfill, rubbish is that hierarchical block is filled, and due to the continuous accumulation of rubbish, constantly compresses and fills out
The effect of working truck is buried, pulling force will be formed in laying, and liner system may be made to lose original effect, in order to prevent
This phenomenon occurs, and anchorage zone generally is arranged at the platform of the top of side slope or segmentation side slope.
The anchoring of refuse landfill pad layer generally uses groove anchoring system, mostly uses rectangular section, by geomembrane with
Protection fabric edge fold is poured with cement concrete in the trench to be fixed.This conventional groove anchoring system work progress
In need to carry out consolidation process to trenched side-wall and bottom surface, project amount is larger, and concreting, health duration are longer on laying,
And concrete anchor solid lower liner layer is such as destroyed, maintenance and reinforcement is difficult.Therefore it is deposited in terms of functionality is with practical performance
In certain limitation.
Summary of the invention
Goal of the invention: the present invention proposes a kind of sanitary filling field laying novel fabricated anchor structure.Be able to solve or
Improve the problems such as conventional groove anchoring system project amount is big, long in time limit, maintenance and reinforcement is difficult.
Technical solution:
Sanitary filling field laying assembled anchor structure, it is characterised in that: the structure setting is in the side slope of refuse landfill；
Including the laying being covered in side slope；
The laying includes the geotextile layer of intermediate antiseepage film and two sides；
The side slope middle section is provided with halfpace；
Glass reinforced plastic anchoring shell is embedded at the halfpace；The laying, which is turned down, to be anchored in shell into glass reinforced plastic and pastes with inner wall
It closes；
The glass reinforced plastic anchoring shell is trapezoid cross section, and base angle is fillet, and top is parallel to the edge of halfpace；
Be provided with glass reinforced plastic anchoring body in glass reinforced plastic anchoring shell, laying be clipped in glass reinforced plastic anchoring shell and glass reinforced plastic anchoring body it
Between；
The glass reinforced plastic anchoring body bosom position is provided with horizontal apertured partition, fills rubble above apertured partition.
Hole bottom for placing glass reinforced plastic anchoring shell is provided with vertical concrete deadman；Glass reinforced plastic anchoring shell passes through expansion
Bolt and rubber sheet gasket are fixed on concrete deadman top.
The glass reinforced plastic anchoring shell is up-narrow and down-wide, bottom width 1000mm, high 800mm；Bottom belt is fluted, is expanding screw
Bolt bolt cap provides space, keeps glass reinforced plastic anchoring shell inner bottom surface without bump.
The glass reinforced plastic anchoring body be trapezoidal, bottom width 880mm, upper width 600mm, ballast grain sizes range 5~
20mm。
Concrete deadman, the long 2.5m of stake, diameter 20cm, bottom is taper, and upper end is equipped with preformed hole.
The glass reinforced plastic anchors thickness of the shell 25mm.The glass reinforced plastic anchors body thickness 15mm.
Advantage and effect:
Sanitary filling field laying novel fabricated anchor structure proposed by the present invention, can be used prefabrication, assembled in situ formula
Construction, component are standardized production, working efficiency can be improved, shorten the construction period.Under the premise of meeting anchorage technology requirement, energy
Enough solve the problems such as conventional groove anchoring system project amount is big, long in time limit, maintenance and reinforcement is difficult.In addition, health of the invention is filled out
A laying novel fabricated anchor structure is buried, other than anchoring function, has concurrently and collects guide percolate function, landfill can be improved
Field percolate treatment effeciency, keeps landfill yard integral layout more scientific and reasonable, safe and reliable.
Detailed description of the invention:
Fig. 1 sanitary filling field laying assembled anchor structure schematic diagram；
Fig. 2 glass reinforced plastic anchors shell detail drawing；
Fig. 3 glass reinforced plastic anchoring body detail drawing；
It is marked in figure:
1 side slope；2 antiseepage films；3 geotextile layers；4 halfpaces；5 glass reinforced plastics anchor shell；6 expansion bolts；7 rubber sheet gaskets；8 is mixed
Solidifying soil anchoring pile；9 glass reinforced plastic anchoring bodys；10 apertured partitions.
Specific embodiment:
The present invention is described further with reference to the accompanying drawing: as shown in Figure 1, the trench at side slope top or halfpace
Slot squeezes into concrete deadman prefabricated in advance in channel bottom, and glass reinforced plastic anchoring shell is then passed through expansion bolt and rubber
Glue gasket is fixed on concrete deadman upper end.It is flat that anchoring shell side grooves are backfilled to top surface one.By backing layer material lower layer geotechnique
Fabric, anti-seepage geomembrane, upper layer geotextile successively turn down in glass reinforced plastic anchoring shell, install glass by laterally inserted mode
Steel anchoring body, inserts rubble in anchoring body on apertured partition.
As shown in Figure 2 and Figure 3, anchoring shell and anchoring body are glass-reinforced plastic material, have intensity height, corrosion resistant advantage.Two
Person's section configuration be all it is trapezoidal, it is up-narrow and down-wide, anchor shell bottom width 1000mm, high 800m, anchoring body bottom width 880mm,
Upper width 600mm, is combined closely by the two and relatively unrotatable feature fixes laying.
The glass reinforced plastic anchors thickness of the shell 25mm.The glass reinforced plastic anchors body thickness 15mm.
Glass reinforced plastic anchoring shell bottom belt is fluted, provides space for expansion bolt bolt cap, keeps anchoring shell inner bottom surface flat
Whole no bump, does not influence the installation of anchoring body.Apertured partition is set among glass reinforced plastic anchoring body, and rubble, partial size are filled up in top
5~20mm of range, percolate are penetrated into inside anchoring body by metalling, and pump drainage in place enters conveyance conduit, and final
Carry out purified treatment.
The long 2.5m of concrete deadman, diameter 20cm, bottom is taper convenient for construction piling, and upper end is equipped with preformed hole, is convenient for
Expansion bolt insertion.Along anchoring shell, longitudinally row's spacing can determine concrete deadman according to factors such as laying stress sizes.
