Description
Technical field
The ecological engineering bag that the utility model relates to a kind of synthetic fibers sandwich construction geotextile and makes.
Background technology
Along with large-scale economic construction, form a large amount of cubic metre of earth and stone slope projects, its slope protecting technique mainly still adopts the hard material bank protection, as: concrete and stone masonry bank protection etc.This class hard material, though can effectively protect the soil body to run off,, a lot of fatal shortcomings are also arranged, for example, its be far from suitable distortion of soft soil matrix is easy to generate crack and destruction.This class hard material bank protection has also destroyed view, has also destroyed ecological environment etc.
In the side slope design recently, grid-turf medium-soft bank protection is adopted in many considerations.This class slope protecting technique makes moderate progress to the compliance of its foundation deformation, and still, the mechanical property of protection side slope then greatly reduces.For the steeper soil-slope of side slope, and the river course side slope that stormy waves is arranged, this class slope protecting technique, to the protection of slope soil, then powerless.
In recent years, ecological environment severe exacerbation, environmental protection problem be subjected to more attention.Therefore, many soft slop protection materials are developed, and " the ecological bag of synthetic fibers geotechnique " slope protecting technique is wherein arranged, and have obtained exploitation." the ecological bag of synthetic fibers geotechnique " is the pocket made from the synthetic fibers geotextile, and this fabric is provided with aperture, the aperture of aperture less (effective aperture 0.2mm) is only seeped water, is not flowed soil, and tension tearing toughness height, inner filling earth material can Turf Culture.Being laid on the upper side slope one by one, thereby protection side slope.
After adopting above-mentioned technology, have following benefit:
1. fetch earth on the spot, do not need other constructional materialss, economize on resources;
2. load earth material on the spot, lay one by one, do not need large-scale construction equipment equipment, easy construction, efficiency of construction height;
3. the ecological engineering bag is laid one by one, can adapt to the distortion on basis;
4. this slope protecting technique, anti-current scour performance is good;
5. on the surface of this bank protection, can Turf Culture, improved view, purified air, improved ecological environment;
6. on rock slope, afforest the more convenient safety of engineering, effect highly significant.
But the product and the production technology of this " the ecological bag of synthetic fibers geotechnique " come from abroad, raw material (synthetic fibers) and fabric technology are required high (seeing the following form), the price of imported product very high (comprising software overhead), the price of import production equipment is very expensive especially; The product of the equivalent constructions that home equipment is produced does not then meet above-mentioned technical requirements, has influenced application and the development at home of this new technology.
The key technical indexes of imported product is as follows:
| Sequence number | Interventions Requested | Unit | Test value | Normative reference |
| 1 | Grip tensile strength | N | 335 | D—4632 |
| 2 | Trapezoidal tearing resistance | N | 175 | GB/T17639-1998 |

The utility model content
For overcoming above-mentioned defective, the purpose of this utility model is to provide a kind of new construction, cost is low, life-span length can utilize existing home equipment to produce synthetic fibers sandwich construction geotextile ecological engineering bag.
For achieving the above object, the utility model synthetic fibers sandwich construction geotextile is made up of two-layer nonwoven and one deck weaving gauze that has aperture, wherein at least, the effective aperture of nonwoven aperture is about 0.2mm, and the effective aperture of weaving gauze is not less than 0.3mm.
Particularly, described weaving gauze is between two-layer nonwoven.
Particularly, described weaving gauze and two-layer nonwoven are hot pressed into one by acupuncture or point.
For achieving the above object, synthetic fibers sandwich construction geotextile ecological engineering bag of the present utility model, make by fabric, described fabric is made up of two-layer nonwoven and one deck weaving gauze that has aperture at least, wherein, the effective aperture of nonwoven aperture is about 0.2mm, and the effective aperture of weaving gauze is not less than 0.3mm.
Particularly, described weaving gauze is between two-layer nonwoven.
Particularly, described weaving gauze and two-layer nonwoven are hot pressed into one by acupuncture or point.
Adopt said structure, make full use of existing manufacturing machine equipment of domestic factory and existing homemade synthetic fibers, comprise short silk or long filament (must satisfy anti-aging requirement); Carry out cloth construction and improve design, make fabric satisfy intensity, effective aperture and water permeability requirement, cost is low, and manufacture craft is simple, and the life-span is long.
Description of drawings
Fig. 1 is the structural representation of the related synthetic fibers sandwich construction geotextile embodiment of the utility model.
Fig. 2 is the structural representation of related another embodiment of synthetic fibers sandwich construction geotextile of the utility model.
The specific embodiment
Related herein nonwoven refers to non-weaving cloth, or is adhesive-bonded fabric.It is a kind of fabric that does not need to spin cotton and weave cloth and form, and just textile staple or long filament is carried out orientation or supports row at random, forms fibre net structure, adopts methods such as mechanical, hot sticky or chemistry to reinforce then and forms.
Related herein weaving gauze refers to natural fiber or chemical fibre is woven into netted or cloth shape product.
