Abstract
The utility model provides a composite geotextile which relates to novel earth work compound material used in the construction engineering of civil construction, water conservancy, railways, harbors, municipal construction, etc. The utility model is mainly used for soft ground treatment and side slope protection for highway, the leakage prevention and the reinforcement of roofs, and inverse filtration, slope protection, seepage prevention, piping, etc. in hydraulic engineering. The utility model comprises a woven geotextile layer, and a non-woven geotextile layer, wherein, the woven geotextile layer and the non-woven geotextile layer are compounded into integration by needling. The geotextile layer can adopt a filament woven geotextile layer or a split film silk woven geotextile layer, and non-woven geotextile layer can adopt a short fibre non-woven geotextile layer or a long fibre needle prick geotextile layer.
Description
What the utility model composite earthwork cloth related to is a kind of novel geosynthetics material that is applied in the construction projects such as civil construction, water conservancy, railway, harbour, municipal administration, mainly act as highway soft foundation processing, side slope protection, anti-filter of roof leak proof, enhancing, hydraulic engineering, bank protection, antiseepage, piping etc.
Commercially available geotextiles generally adopts the individual layer woven geotextile at present, though woven geotextile intensity is higher, but because of reasons such as raw material, technology weaving mode cause aperture and infiltration coefficient less, and do not reach designing requirement in the engineering constructions such as civil construction, water conservancy railway, harbour, municipal administration, the another kind of individual layer non-woven geotextile that adopts, though good penetration coefficient and anti-filter characteristic are arranged, can't construct because of intensity is less than normal.
The purpose of this utility model is to exist weak point that a kind of composite earthwork cloth is provided at present geotextiles, adopt woven geotextile and non-woven geotextile to be combined with each other by acupuncture, make joint product have high strength, good penetration performance and peel strength, satisfy the construction project needs.
Composite earthwork cloth takes following scheme to realize: the composite earthwork cloth structure comprises the woven geotextile layer, non-woven geotextile (non-woven geotextile) layer, and woven geotextile layer and non-woven geotextile layer are combined into integral body by acupuncture.Woven geotextile can adopt long filament woven geotextile layer or split yarn geotextiles (braided geotextile).Non-woven geotextile (non-woven geotextile) layer can adopt staple fibre non-woven geotextile layer or terylene long fiber acupuncture geotechnique layer of cloth etc.
Composite earthwork cloth is because employing individual layer long filament woven geotextile and individual layer non-woven geotextile (staple fibre non-woven geotextile) are made integral body through the acupuncture combination process, combine long filament woven geotextile intensity height, the advantage that non-woven geotextile aperture and permeance property are good, make composite earthwork cloth have high strength, good penetration performance and peel strength, the long filament woven geotextile combines with non-woven geotextile and closely is difficult for peeling off convenient construction.Can be widely used in making novel geosynthetics material in the construction projects such as civil construction, water conservancy, railway, harbour, municipal administration.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is composite earthwork cloth structural representation Fig. 1.
Fig. 2 is composite earthwork cloth structural representation Fig. 2.
With reference to accompanying drawing 1 composite earthwork cloth structural representation Fig. 1, composite earthwork cloth is combined into integral body by woven geotextile layer 1 and non-woven geotextile layer 2 (non-woven geotextile layer) through acupuncture, woven geotextile layer 1 adopts the long filament woven geotextile, wherein the long filament woven geotextile is to adopt the 1000D polyester filament by 90～96/10cm of organizine density, 80～88/10cm of tram density, (ideal format 94 * 86 thread counts) are woven into 230g/m
2Woven geotextile, non-woven geotextile layer 2 adopts the staple fibre non-woven geotextile, and the staple fibre non-woven geotextile adopts the polyester staple fiber 6D and the 2.5D acupuncture of two kinds of different fiber numbers to become 150g/m
2Geotextiles, wherein 6D fiber proportion is between 50～70%.The woven nonwoven composite earthwork cloth of the long filament design objective of making through said structure requires to reach:
The requirement of the woven nonwoven composite earthwork cloth of long filament design objective
With reference to accompanying drawing 2 composite earthwork cloth structural representation Fig. 2, composite earthwork cloth is combined into integral body by split yarn woven geotextile layer (braided geotextile layer) 2 and non-woven geotextile layer 2 (non-woven geotextile layer) through acupuncture, woven geotextile layer (braided geotextile layer) 2 adopts split yarn long filament woven geotextile (flat filament woven geotextile), press 35～42/10cm of organizine density, 30～40/10cm of tram density (ideal format 39 * 33 thread counts) is woven into 230g/m
2, non-woven geotextile layer 2 can adopt the polyester staple fiber 6D of two kinds of different fiber numbers and 2.5D acupuncture to become 150g/m
2Geotextiles.Wherein 6D fiber number proportion is between 30～50%.The braiding nonwoven composite earthwork cloth design objective of making through said structure requires to reach:
Braiding nonwoven composite earthwork cloth index request
Claims (3)
