Abstract
The utility model of a geo-textile sand filling bag relates to the geo-textile bags used in water coastal areas and underwater protection shores, dike dams, protection bottoms and diking projects. The technical problem which the utility model wants to solve is to get rid of the sand leakage of sand filling bags. The utility model using the sewed geo-textile bags is characterized in that the acupuncture combined geo-textile is spliced and sewed respectively with the knitting cloth or machine cloth above and under the bag body, thus forming the adjacent areas of the geo-textile bag body. The utility model is suitable for the water coastal areas and underwater protection shores, dike dams, protection bottoms and diking projects.
Description
Technical field:
The utility model relates to the littoral geotextile bag of shore protection, bank protection, river bottom protection, embanking project use under water that reaches in waters.
Background technology
Existing geotextile filling sand pocket is generally made by the single-layer polypropylene woven cloth, is used for back-up sand shore protection, river bottom protection or fill, and this geotextile bag bagging weight is generally 130～150g/m
2, fabric intensity is greater than 1000N/5cm, about the 0.1～0.2mm of aperture, and transmission coefficient 10
-3～10
-4Cm/s, because the bagging material is thin, if timely mask in case be subjected to wave impact, very easily causes the local sand phenomenon of leaking, geotextile bag is leaked sand and then can be caused whole engineering to fail.
Summary of the invention
The utility model technical issues that need to address are to avoid bagging to leak sand.
The technical solution of the utility model adopts the geotextile bag back-up sand make, the bag periphery that it is characterized in that geotextile bag with the acupuncture composite earthwork cloth respectively with above the bag, following polypropylene woven cloth or the woven cloth splicing of polypropylene sew up.
The utility model is owing to adopt the acupuncture composite earthwork cloth at bag periphery, and this composite earthwork cloth is compound with nonwoven acupuncture by woven cloth or woven cloth, because its anti-filter performance is good and intensity is high, the composite geotextile bag is had avoid the leak technique effect of sand.Bag will be capped when the geotextile bag placement in layers at the position up and down, be subjected to the wave flow action less, be in less important position, therefore still can adopt the woven cloth of polypropylene woven cloth or polypropylene, get its advantages of cheap price.
Description of drawings
Accompanying drawing 1 is the schematic diagram of the utility model bag.
Accompanying drawing 2 is fourth crack structure schematic diagrames.
Accompanying drawing 3 is overseam structural representations.
The specific embodiment
Implement mode of the present utility model and be to adopt the geotextile bag of making, the bag periphery 1 of this geotextile bag adopts by woven cloth or woven cloth and nonwoven acupuncture composite earthwork cloth, this acupuncture composite earthwork cloth weight generally 〉=300g/m
2, wherein the woven cloth weight of polypropylene woven cloth or polypropylene general 〉=150g/m
2, terylene short fiber nonwoven weight is general 〉=150g/m
2, the geotextiles aperture after acupuncture is compound can be by narrowing down to below the 0.07mm more than the original 0.1mm, and vertical transmission coefficient is by original 10
-3~ 10
-4Cm/s increases to 10
-2More than the cm/s, fabric thickness is increased to more than the 2mm about by original 0.5mm, and fabric has kept high strength, the characteristic of low elongation, and protect the original woven of the permeable effect of sand and had more significantly and improve; The acupuncture composite earthwork cloth of bag periphery 1 splices with top 2, following 3 of bag respectively to be sewed up, and the mode of making can adopt fourth stitch or overseam method, and seam crossing Strong degree is greater than 70% of source textile design strength, and seam crossing preferably adopts two road sewing lines 4; The consumption of acupuncture composite geotextile and polypropylene woven cloth or the woven cloth of polypropylene is with using position, instructions for use and bag size to decide in the geotextile filling sand pocket; The usage ratio of acupuncture composite earthwork cloth and polypropylene woven cloth or the woven cloth of polypropylene can be 1: 1.In a word, in line with the principle of economic and reliable.
Claims (5)
1, a kind of geotextile filling sand pocket is characterized in that the bag periphery of geotextile bag is sewed up with top, the following polypropylene woven cloth or the woven cloth splicing of polypropylene of bag respectively with the acupuncture composite earthwork cloth.
2, geotextile filling sand pocket according to claim 1 is characterized in that the acupuncture composite earthwork cloth weight 〉=300g/m of bag periphery
2, the woven cloth weight 〉=150g/m of polypropylene woven cloth or polypropylene wherein
2, terylene short fiber nonwoven weight 〉=150g/m
2, the geotextiles aperture≤0.07mm after acupuncture is compound, vertical transmission coefficient 〉=10
-2Cm/s, fabric is thick 〉=2mm.
3, geotextile filling sand pocket according to claim 1 and 2 is characterized in that the acupuncture composite earthwork cloth of bag periphery and the above and below connecting method of bag adopt fourth seam or overseam to make.
4, geotextile filling sand pocket according to claim 1 and 2 is characterized in that the usage ratio of acupuncture composite earthwork cloth and polypropylene woven cloth or the woven cloth of polypropylene can be 1: 1.
5, geotextile filling sand pocket according to claim 3 is characterized in that the usage ratio of acupuncture composite earthwork cloth and polypropylene woven cloth or the woven cloth of polypropylene can be 1: 1.
