Detailed description of the invention
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
The utility model provides a kind of water body purification leakage preventing structure, described structure comprise successively from lower to upper in vertical direction degree of compaction be not less than 90% soil matrix 1, basic unit 2, bed course 3, impervious barrier 4, purifying layer 5, topping 6 and surface layer 7.
Wherein each layer structure and act on as described below:
1) soil matrix 1---soil matrix 1 is generally original soil, and soil matrix 1 must be closely knit, flawless, even, stable, smooth, and degree of compaction is not less than 90%.
2) basic unit 2---basic unit 2 is generally middle layer of sand, coarse sands layer or both mixed layers, plays levelling and protective effect.
3) bed course 3---bed course 3 generally adopts fine sand to lay, and it is 2 ~ 8cm that described basic unit 2 and bed course 3 amount to thickness, and the gradient situation according to soil matrix 1 is carried out smooth, and gauge allowable variation is less than 1cm.
4) impervious barrier 4---described impervious barrier 4 adopts volume ratio to be that the ratio of 1:5 ~ 15 mixes by soil-solidified-agent and ventilation anti-seepage sand, and without the need to adding water, thickness is 1 ~ 4cm, and lay evenly, gauge allowable variation is less than ± 0.5cm.
5) purifying layer 5---be made up of zeolite and phosphobacteria, nitrobacteria, wherein phosphobacteria: nitrobacteria: zeolite adopts 1 ~ 3:1 ~ 3:50 ~ 100 (weight ratio), thickness 5 ~ 8cm, the heavy metal, N element, the P element that act as in absorption, fixing water body of purifying layer 5, reach the effect of purifying water body.
6) topping 6---described topping 6 adopts non-woven fabrics, and specification is not less than 70g/m
2, thickness is not less than 0.8mm, fabric width 4 ~ 6 meters; Or adopt the existing medium coarse sand in river course, select 4.75 ~ 0.3mm (4 ~ 50 order) husky, namely maximum particle diameter is no more than 4.75mm in principle; Or adopt backfill, gravel etc.
7) surface layer 7---surface layer 7 is mated formation planting soil, and thickness is not less than 35cm, and soil property should be beneficial to the growth of design water plant; Or building block of mating formation, thickness is not less than 6cm, good looking appearance; Or gravel of mating formation, thickness is not less than 20cm.
Further, described impervious barrier 4 also comprises GCL or clay.
Preferably, described GCL is by clamp high-quality sodium bentonite between two layers of geosynthetics, is composited by boundling acupuncture.It has following advantage:
1. antiseepage is good: its permeability is 5 × below 10-11m/s, is better than the impervious effect of 1 meter of thick clay compaction.
2. timeliness is long: because Na-bentonite soil series natural inorganic material, even if experience is long-time or surrounding environment changes, also aging or corrosion phenomenon can not occur, therefore water resistance is lasting.
3. intensity is high: pliability is excellent, and make its resistance to overturning good, tensile strength is high, can adapt to different terrain, the particularly distortion that causes of sedimentation.
4. selfreparing: have good oneself and keep and self-regeneration performance, can self-regeneration for local failure, is not afraid of aquatic plant root system and punctures, can self-repair about 2mm crack.
5. construction easily: compare with other waterproofing materialss, and construction is relatively simple, do not need heating and paste.Only need carry out being connected and fixing with swell soil powder and nail, packing ring etc.Special inspection is not needed, if find that waterproof defect is also easily keeped in repair after construction.GCL be in existing waterproofing materials the construction period the shortest.
6. scope is wide: do not affect by temperature: also can not brittle failure under cold climate conditions.
7. environmental protection: because swell soil is natural inorganic mineral matter, to human body and environmentally friendly, belongs to high-quality environment-friendly waterproof material, and there will not be aging, reach more than 50 years application life.
GCL is compared with ventilation anti-seepage sand constructability, cheap, but air permeable effect is poor.
Preferably, described clay is a kind of hydrous alumino silicates mineral matter, is a kind of small crystal, has certain viscosity.After clay mineral water is moistening, there is plasticity, can be out of shape under less pressure and can maintain the original state for a long time, and specific area is large, with elecrtonegativity on particle, therefore there are good physical adsorbability and chemical mobility of the surface, there is the ability with other cation exchange.
Clay core is one of traditional impervious form, have gather materials on the spot, simple and easy, the construction quality of constructing is easy to the features such as control.Owing to having the characteristic of automatic depression consolidation in water, constructional deficiency can be made automatically to heal, and the frost-heaving deformation on basis can be adapted to, the frost heave crack of generation can in Spring Freeze-thawing process clear-cutting forestland.
Clay is in ventilation anti-seepage sand and these three kinds of materials of GCL, and construction cheaply degree, price height and air permeable effect all mediates, and resultant effect is better.Meanwhile, clay is pollution-free, useful to the plant growth of surrounding.This method process of bank, does not block the interchange of surrounding material, favourable to the ecological environment of surrounding.
The advantage obtained of the present utility model is: the water body purification leakage preventing structure that the utility model proposes, adopt the form of structure of composite material antiseepage, and add phosphobacteria and nitrobacteria, to promote the fixing of N in water body, P element, while reducing the organic matter in water, also improve water quality.Meanwhile, by the compound action of multilayer impervious material, while antiseepage, do not hinder gas exchanges, the oxygen in soil is discharged in water body, increase Dissolved Oxygen in Water content, improve water body self-purification ability.This ventilation anti-seepage structure makes full use of each material property advantage, in and drawback, reduce construction costs, improve the ecological effect of water body.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
