Abstract
The utility model relates to a needling bonded reinforcement non-woven geotextile, which is characterized in that one layer of polypropylene woven fabrics on one side of a fibre web, and the fibre web prickles rerepeatedly facing to the polypropylene woven fabrics, which causes the fibre web and the woven fabrics to entwist each other by the fiber and then are combined into a whole, the cost of the geotextile is more than 40 percent lower than that of an ordinary staple fibre geotextile of the same index.
Description
The utility model relates to a kind of non-woven geotextile that is used for engineering construction.
Non-woven geotextile is a kind of novel engineering construction material, comes out over 50 years, and aspects such as the draining in railway, highway, native stone dam, bay isolith geotechnique journey, filtration isolation, reinforcement have obtained using widely.The present widely used regular staple acupuncture geotextile that has under its unit square rice quality, generally is 200g/m to powerful index in length and breadth
2Geotextiles, the tension brute force is 200N/5cm, 400g/m
2Geotextiles, tensile strength is 400N/5cm.Often to select 400g/m for use on the engineering
2Even the geotextiles of higher unit square rice quality, but because its price is higher, it is a lot of to cause construction costs to rise, and has therefore restricted the application to non-woven geotextile.
The purpose of this utility model is to guarantee to reduce the cost of non-woven geotextile significantly under every intensity index prerequisite.
To achieve these goals, the utility model has adopted following technical scheme: at adduction one deck polypropylene woven cloth of fibre web, go out fiber and entanglement mutually by fibre web towards the repeated puncture of polypropylene woven cloth, fibre web and polypropylene woven cloth are combined as a whole.
Owing to adopted technique scheme, the acupuncture of making combination geotextile tension brute force is more than 400N/5cm, and mass area ratio only is 250g/m
2, and kept original 400g/m
2Every performance of geotextile, but its cost has reduced more than 40%.As select 100g/m for use
2Polypropylene woven cloth, the powerful 550N/5cm of its warp-wise tension, the powerful 500N/5cm of broadwise tension is respectively with 100g/m
2, 150g/m
2Fibre web acupuncture combination, its every index is as shown in the table:
| Polypropylene woven cloth | 100g/m 2 | ||
| Fibre web | 100g/m 2 | 150g/m 2 | |
| Tensile strength | Broadwise N/5cm | 350 | 400 |
| Warp-wise N/5cm | 350 | 400 | |
| Bursting strength | CBR?N | 1080 | 1290 |
| Garden ball N | 400 | 46.1 | |
In order to further specify the utility model, following routine accompanying drawing provides a most preferred embodiment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 fibre web, 2 polypropylene woven cloth, 3 fiber pins.
As shown in Figure 1, staple fibre through shredding, combing, one-tenth net, assist into the fibre web 1 of certain square metre of quality, superimposed one deck polypropylene woven cloth 2 below it feeds needing machine together, with 40-50 pin/cm
2Pin pin close, 7-9mm dark,, make fiber pin 3 pierce through woven cloth 2 and tangle mutually towards woven cloth 2 repeated punctures by fibre web 1, fibre web 1 and polypropylene woven cloth are combined as a whole.
Claims (1)
1, acupuncture combination non-woven geotextile is characterized in that going out fiber by fibre web towards the repeated puncture of polypropylene woven cloth at adduction one deck of fibre web polypropylene woven cloth, leans on the mutual entanglement of fiber to make fibre web and polypropylene woven cloth be combined into integral body.
