Description
Technical field
Structures pattern is disposed the present invention relates to a kind of river polluted bed mud earth's surface fill, more particularly to a kind of its is applied to
The structures device of the river polluted bed mud processing of the flood control capacity of embankment is gushed in the safe disposal of river polluted bed mud and reinforcement river.
Background technology
With industrial development and immoderate discharge of wastewater, the bed mud that some Chinese rivers are gushed is by different degrees of heavy metal
Pollution.Bed mud is an important environment support of the natural ecosystem of rivers system, and the most basic result of sediment pollution is to bring water pollution
Pollutant is enriched with benthon, pollutant will enter human body by biological chain, endanger human health.
At present, river gushes the Disposal Measures of bed mud and is divided into following a few classes：Fixation in situ, in-situ treatment；Dystopy is fixed, at dystopy
Reason.Fixation in situ and in-situ treatment are that river gushes bed mud and do not dredge and directly eliminate bed mud using solidification or the means such as biodegradation
Pollution behavior, dystopy processing and dystopy fix be then will after Sediment Dredging carry out move away from processing.In current in-situ treatment technology
Research and application it is more be sediment in-situ ecological reestablishment, such as community of aquatic organism recovery technique passes through Damaged River System
Restoration of the ecosystem makes river have complete Food-Chain System, the self purification of enhancing river in itself with rebuilding.But, it is overall and
Speech, in-situ treatment technology is still immature, therefore, and current river gushed and fixed using dystopy and dystopy processing more than bed mud, that is, takes certain
Technological means carry out Sediment Dredging, after dredging dystopy in bed mud pollutant carry out curing/stabilizing processing, or according to
Demand carries out physics, chemistry, biological treatment, then bed mud is integrally dehydrated, solidified at landfill, this dystopy fixation and dystopy
Reason moves away from out river course and river levee.
Do not consider to accommodate using river levee itself it can be seen that the method that bed mud dystopy is fixed and dystopy is handled is gushed in current river
The space of polluted bed mud, adds the expense of strange land carrying and the soil space of strange land landfill.
The content of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art there is provided the structures that a kind of river polluted bed mud is handled
Device, the device takes full advantage of the disposal space of river levee itself, no by designing a kind of polluted bed mud earth's surface fill structures
Produce strange land carry great number freight, improved while safe disposal polluted bed mud river levee flood control safety coefficient and
Landscape requirement, sediment technology and river levee flood control function are unified.
The present invention is achieved through the following technical solutions：The structures device of river polluted bed mud processing, including phase
To a pair of L-shaped armored concrete of setting build mould, the feature transfer barrier flexible cushion with seepage-proof water guiding and defencive function,
For vegetation growth and with preventing from infiltrating the ecological coating of function, diafiltration exhaust system and with collecting structures device
The open caisson of internal liquid body exudate function；The L-shaped armored concrete, which builds mould, includes horizontal sides and vertical edges, two L-shaped reinforced concretes
Soil builds mould and is spliced into the internal reinforced concrete constructional work for U-shaped space in opposite directions, and horizontal sides are located at U-shaped space bottom, the work(
Energy property transfer barrier flexible cushion is overlying on U-shaped space bottom, and the solidification polluted bed mud is placed in feature transfer barrier flexible pad
Build concordant at the top of the vertical edges of mould on layer and with L-shaped armored concrete, the L-shaped armored concrete, which to be built, be provided with the outside of mould
For support L-shaped armored concrete build mould vertical edges stone masonry support system, it is dirty that the ecological coating is covered in solidification
Dye bed mud and L-shaped armored concrete are built on mould；The diafiltration exhaust system is obliquely installed, two ends respectively with U-shaped space and heavy
Well is connected；The open caisson is provided with several, is arranged in the side that L-shaped armored concrete builds mould.
L-shaped armored concrete, which builds mould, to be used to cover feature transfer barrier flexible cushion, solidification polluted bed mud and ecology
Cap rock is stored and positioned fixation；The setting of stone masonry support system, can make support L-shaped armored concrete build mould and be allowed to position
Without shifting；Diafiltration exhaust system is obliquely installed, and is directed at beneficial to by the liquid oozed out inside device row in open caisson.
The feature transfer barrier flexible cushion includes antiseepage barrier layer and drainage blanket, and the drainage blanket is located at institute
State on antiseepage barrier layer, antiseepage barrier layer includes the first clay protective layer, by non-woven geotextile and smooth surface HDPE from bottom to top
The flexible cushion that geomembrane is made, epoxy resin has been poured in the flexible cushion stress concentration part；The drainage blanket is
The drainage blanket being made up of the rubble filter layer of polyethylene filament non-woven wraps.Feature transfer barrier flexible cushion is by antiseepage
Barrier layer and drainage blanket composition, with antiseepage, water guide and defencive function；Epoxy has been poured in flexible cushion stress concentration part
Resin is beneficial to ensure its closure.
The solidification polluted bed mud is according to 1 by cement and polluted bed mud:7~1:Rammed after 9 mass ratio mixing
Real solidification polluted bed mud, it meets unconfined compressive strength qu for 0.5~4.0MPa, cohesive force c=0.2~0.3qu, inside rubbed
Wipe angle φ=20 °~30 °, safety coefficient Fs ＞ 1.30.
The ecological coating includes the second clay protective layer, rubble filter layer and vegetable layer from bottom to top.Ecology covering
The setting of layer, possesses growth vegetation and the function of preventing from infiltrating.
It is an advantage of the invention that：The present apparatus degree of modularity is high, simple in construction, easy construction, with miniaturization, lightweight
The advantages of, while feature transfer barrier flexible cushion and small-sized open caisson can effectively collect the unexpected rainwater infiltrated and solidification is polluted
The percolate that bed mud itself dialysis is produced.Whole process is, in a completely enclosed state, environment generation will not to control to external world
Secondary pollution during reason.
