Description
Technical field
It the utility model is related to a kind of Seepage structure.
Background technology
Antiseepage in soil surface i.e. by building impervious barrier, to prevent that concrete application has channel to Liquid Penetrant into soil
The field such as antiseepage, contaminated site antiseepage.Seepage control measure main at present has following several：
1) soil compaction seepage control measure：
The core of soil compaction antiseepage is exactly：The tightly compacted coating impervious barrier of one layer of process is laid in soil surface.This
Kind impervious barrier primary raw material involved in structure includes clay and sand clay both types.Due to above-mentioned two class
The materials relatively convenient of the soil body, thus the cheap but acquired effect of cost of whole soil compaction seepage control measure is pole
To be significant.Also need to pay special attention to is a bit：Early stage the higher earth material of institute's compacted depth, its substantial anti-seepage effect
It is higher.But such seepage control project is in frost resistance and poor durability, thus can only be applied to region flow velocity it is smaller and
The relatively mild region of amblent air temperature.
2) concrete lining seepage control measure：
Concrete lining seepage control measure be in various seepage prevention measures using the most generally with extensive seepage control measure it
One.The main advantage of concrete lining antiseepage is：It is accessible using its with good antiseepage and shock resistance effect
Filter loss reduces ratio and has reached 95% or so.But such a seepage control measure is there is also certain application limitation, i.e., its for
The adaptability of deformation is relatively low.And because it has strict requirements for sand material, thus for lacking the region of sand material
For, cost is also one of critical problem.
3) coating materials seepage control measure：
In order to resist concrete lining seepage control measure exist in terms of deforming adaptability the problem of, portion flow rate can be directed to
Relatively small antiseepage region introduces the seepage control method based on coating materials.For geomembrane, because it is soft
Property, be respectively provided with extremely prominent advantage in terms of drawing-resistant function power and extensibility, thus can be acted in antiseepage application,
Simultaneously as the quality of geomembrane is lighter, every square metre of materials are few, but such a seepage control measure anti-impact force is poor, it is easy to broken
Damage and do not reach anti-seepage effect.
Utility model content
In view of the above-mentioned problems, the utility model, which provides one kind, can improve shock proof Seepage structure.
To reach above-mentioned purpose, a kind of Seepage structure of the utility model, described Seepage structure includes：Under
The supreme soil set gradually, waterproof layer and surface overburden layer；Wherein, the waterproof layer includes setting gradually from the bottom to top
The first impervious barrier, soil consolidation layer and the second impervious barrier.
Further, first impervious barrier and second impervious barrier are sprinkling EVA emulsions and/or polyaminoester emulsion
Soil consolidation form.
Further, first impervious barrier and second impervious barrier are geotextiles and bitumen layer.
Further, the concentration of the EVA emulsions is 5%-20%；The concentration of the polyaminoester emulsion is 5%-20%.
Further, the soil consolidation layer is stirred solidification for bentonite, fibrous material, soil and water and formed.
Further, fibrous material be carbon steel fiber, stainless steel fibre, alkali resistant glass fiber, carbon fiber, nylon fiber,
One or more in aramid fiber, basalt fibre, PVA fibers, EVA fibers, a diameter of 1-1000 μ of the fibrous material
M, length is 3-30mm.
Further, the bentonite particle diameter is the mesh of 100 mesh -500.
Further, the soil consolidation layer is stirred solidification by the raw material of following mass parts and formed：Bentonite 90-
100 mass parts, soil 10-100 mass parts, fibrous material 1-30 mass parts, water 10-80 mass parts.
A kind of Seepage structure of the utility model, by waterproof layer by three-decker, greatly improves anti-seepage effect so that
Infiltration coefficient is less than 10-10cm/s；And construction is simple, do not need heavy mechanical equipment and lot of materials, cost low；It is applied to
The antiseepages such as the anti-seepage of channels, contaminated site risk control, road pavement require higher field.
Seepage structure of the present utility model, waterproof layer are the three-layered nodes by two layers of impervious barrier and one layer of soil consolidation layer
Structure forms, and anti-seepage effect is excellent；Soil consolidation layer is formed by bentonite, fibrous material, soil and water consolidation, because bentonite has
Have the advantages that expansion rate of water absorption is big, speed of expansion is fast, ageing-resistant, anticorrosive, and fibrous material adds, soil can be improved again and consolidated
The bending resistance of layer is tied, so seepage control technique of the present utility model not only good seepage-proof property, and external force resistance impact and resistance to deformation
Ability is strong, and compare no soil consolidation layer, and only one layer of geotextiles antiseepage film, has certain anti-seepage effect, but external force resistance rushes
Hit poor, compare only bentonite, soil consolidation layer, bending resistance is poor, and anti-seepage effect does not have the utility model seepage control technique yet
It is good.
