Detailed description of the invention
Referring to figs. 1 through Fig. 4, below the reinforcement stabilized zone for Study on Reinforced Embankments Using structure according to the present invention is illustrated.
This stabilized zone 1 include long reinforcing fiber 12 and around or close longitudinal sheath 11 of long reinforcing fiber 12.Sheath
11 are made up of the functional poly condensation material containing functional polyolefin (Po-f) at least in part.
Polyolefin is saturated fat polymer, it is alternatively that, replace by olefin polymerization (also referred to as olefine) or obtain
Described polyolefin.
Functional polyolefin can be selected from functionalized polyethy-lene class, functional poly propylene class or such as functionalization ethylene vinegar
Vinyl acetate (EVA) such functional olefin copolymers.Preferably, functionalized polyethy-lene class, especially functionalization line style are selected
Low Density Polyethylene.
" functionalization " word is interpreted as by with containing functional group or the chemistry of unsaturation state in the linguistic context of the present invention
Element replaces polyolefin or by chemical element is grafted on polyolefin change polyolefin.Change polyolefin to also result in
Unsaturation state is formed in polyolefin chain.The functional group of its part can form covalent bond by the material with reinforcing fiber 12
Or hydrogen bond and react with it.
Especially, functional group is selected from mono hydroxyeicosatetraenoic acid acid anhydride or dihydroxy anhydride.
Such as, the chemical element of the hydrogen atom in polyolefinic carbochain is replaced to may is that maleic anhydride or acid phthalic anhydride base
Group or acrylic acid；Maleic acid anhydride group is the most frequently used.
Large number of functional group is needed not be provided in Po-f.It practice, Po-f functionalization is usually 0.01wt.% extremely
45wt.%.More than 45wt.% functionalization, it it is the most no longer polyolefin.Advantageously, functionalization degree be 0.01wt.% extremely
30wt.%, preferably 0.01wt.% to 15wt.%, or preferably 0.01wt.% to 5wt.%, for 0.1wt.% extremely
2wt.% is more preferably.
The functionalization degree of Po-f must be understood as the quality and functionality of the functional group reacted with polyolefin
Ratio between polyolefin Po-f gross mass.Can also be by the initial polyolefin (Po-nf) of non-functionalized and functional polyolefin
Between hydrocarbon Po-f, it is calculated by the gain of quality.Such as, if 10g maleic anhydride and polyolefin there occurs reaction,
The gross mass of Po-f is 100g, then functionalization degree in mass is then 10wt.%.Functional poly condensation material can comprise
The mixture of Po-f or the Po-f nand function fluidized polymer of 100wt.%.This non-functionalized polymer is and functional polyolefin
The polymer of hydrocarbon coupling, say, that its mixture long-time stable, and do not observe separated.It may be said that they are complete
Miscible.Non-functionalized polymer be preferably selected from non-functionalized polyethylene kind (PE-nf), non-functionalized polypropylene (PP-nf) or
Person's such as ethylene vinyl acetate (EVA-nf) such olefin copolymer.First-selected non-functionalized polymer is linear, low density
Polyethylene (LLDPE-nf).
Advantageously, the mass ratio between Po-f nand function fluidized polymer is between 1:9 to 10:0.Po-f is (best
It being LLDPE-f) mass ratio between nand function fluidized polymer (preferably LLDPE-nf) is between 1:4 to 1:1.
Functional poly condensation material 111 can have functionalization gradient, reaches maximum, away from increasing when contacting with reinforcing fiber 12
It is gradually lowered during strong fiber 12.Gradient can be continuous print or progressively.
Sheath 11 may also include around or a non-functionalized region 112 of closing function polymeric material 111.Therefore may be used
To reduce the cost of sheath 11, because generally non-functionalized polymer (or Po-nf) does not has Po-f expensive.Non-functionalized region
Polymer can be identical or different with the mixture becoming functional poly condensation material, and selected from mixture referred to above
Material.
One or more passage 13 can be formed in sheath 11, in these passages 13, stretch reinforcing fiber 12.Increase logical

Become the interaction strength between key element.Preferably, the quantity of passage is 5 to 20.
Reinforcing fiber 12 is made up of any material that can strengthen stabilized zone tensile strength.Reinforcing fiber is by selected from polyethylene
Alcohol (PVAL), polyesters, quartz glass, linear polyamide or aromatic polyamides (aromatic polyamides) and metal or its mixture
Material is made.If using two or more material, the reinforcing fiber being made up of a kind of specified material can flock together, or
The component of the reinforcing fiber in each passage 13 can be different from another passage, it is, however, preferable to the enhancing in each passage 23
The component of fiber is the most identical.
In mentioned fiber, first-selected PVAL fiber.This is because, with polymer, glass, linear polyamide, fragrance
Polyamide is different with metal, and these materials character (especially constituting the pH value of the soil of the part of component of banketing) to banketing is no
Sensitive.
Reinforcing fiber 12 can be arranged in the sheath 11 parallel with its length easily, and parallel to each other.Described enhancing
Fiber can be crude fibre, is the most not spun into fiber.
Reinforcing fiber 12 can also be presented in line parallel to each other." line " is produced by textile fabric.Also
That is, fiber orients the most in the same direction, and is threaded together.The tensile strength of the line being made up of fiber is higher than being that
The tensile strength of this all fibres being arranged side by side；It practice, weaving enhances the mechanical performance of fiber.
Reinforcing fiber 12 can also be presented in strand parallel to each other or cable, such as institute in file EP2171160
State.Several lines weaved or is woven together, being formed one " strand ".Several strands weaved or is woven together, forming one
Individual " cable ".Because strand and cable produce by gathering a plurality of line, thus its appearance unlike fiber or line appearance that
Smooth.Therefore, strand or the concave-convex surface of cable, namely there are recess and projection in its surface.Around or close reinforcing fiber
The functional poly condensation material of 12 is suitable for these recesses and protruding shape, therefore, it is possible to mechanical strength is increased to tensile strength
On, increase the adhesion between reinforcing fiber 12 and sheath 11 further.
Reinforcing fiber 12 can also be made up of a kind of mixture, described mixture include crude fibre, line, strand and cable it
In at least two element.
Sheath 11 can include at least one high longitudinal edge 113 adhered to, and this height adheres to longitudinal edge does not has reinforcing fiber,
There is notch 114 (see Fig. 3 and Fig. 4), as described in file EP2247797.The notch on longitudinal edge 113 that this height adheres to
The effect of 114 is banketing of friction Study on Reinforced Embankments Using structure, thus stabilized zone 1 is held in place by.
It is said that in general, and as described above, the length in stabilized zone 1 is about 3 meters to 10 meters, however can also arrange longer or

Or (Fig. 6) of braiding.In the case of stacked warp thread and weft yarn, some or all stabilized zone 1c of warp thread is fixed to intersecting
The stabilized zone 1t of the weft yarn intersected therewith at point 101.In the case of braiding warp thread and weft yarn, can the most partially or completely
Ground is fixed to the stabilized zone 1c of warp thread the stabilized zone 1t of weft yarn, but is not necessary to so；This is because braiding can be relative to
Weft yarn maintains warp thread, and vice versa.The stabilized zone putting warp thread is preferably executed with the position that the stabilized zone 1t relative to weft yarn is 90 °
1c, the stabilized zone 1c of warp thread intersect with the stabilized zone 1t at right angle with weft yarn.But, the invention is not restricted to be oriented so as to, warp thread
Stabilized zone 1c is also possible with other relative orientation any of the stabilized zone 1t of weft yarn, such as 60o and 45o.
Can be by the stabilized zone 1t of the stabilized zone 1c of hot weld or the warp thread that is adhesively fixed with weft yarn.For polyolefin sheath
Known welding method is hot jet welding, minute surface welding, thermal wedge weldering, ultrasonic bonding and IR welding.
Stabilized zone 1 as above is used for building Study on Reinforced Embankments Using structure 2 (Fig. 7).In addition to stabilized zone 1, this reinforcement road
Embankment structure 2 also includes banketing 21.Stabilized zone 1 is flatly executed and is put in the banketing of one or more levels.In a variant, or
