Description

A kind of warp knit composite earthwork cloth
Technical field
The invention belongs to geotechnical process field, and in particular to a kind of warp knit composite earthwork cloth.
Background technology
Refuse landfill, dykes and dams, airport, railway bed, highway construction need to carry out the laying of roadbed initial stage, in engineering In use, to prevent subgrade settlement, it is necessary to use substantial amounts of geotextiles, geotextiles are entered to exercise when ground is laid With ground being allowed not sunk when running into precipitation very serious, protect the safety of ground, but many grounds are all at present It is the structure using one layer, such structure can cause the use quality of geotextiles to decline, once the ground of strong acid is run into, quickly Will be by leak at geotextiles corrosion, the geotextiles to start a leak just have the sagging risk of ground in respective regions so that ground The shock strength of base cannot be guaranteed, and can also influence the service life of road laid on roadbed indirectly.
Geotextiles, also known as geotextile, it is that the water penetration geotechnique formed by synthetic fibers by acupuncture or braiding synthesizes Material.Finished product is cloth-like, and general width is 4-6 rice, and length is 50-100 rice.Geotextiles have outstanding filtering, draining, every From, reinforcement, antiseepage, protective action, have that in light weight, tensile strength is high, good penetrability, high temperature resistant, anti-freezing, ageing-resistant, resistance to Corrosion.Geotextiles are divided into Woven geofabric and non-woven geotextile.
Non-woven geotextile is to be arranged to reticulate by different equipment and technique by long filament or chopped fiber, by acupuncture etc. Technique allows different fibers to be interweaved together, and mutual entanglement set makes fabric specification, allow fabric sofetening, it is plentiful, abundant, It is stiffening, meet requirement to reach different thickness, non-woven geotextile has good fabric gap, there is good attachment Power, because fiber softening has certain lear energy, while there is deformation adaptability well, while have well Flat drainage ability, soft surface Multiple level have good coefficient of friction, by increasing capacitance it is possible to increase the adhesive ability of grogs etc., can prevent Fine particle is by preventing the loss of particulate matter while eliminating excessive moisture, soft surface has good protective capability.It Can play good filtering, isolation, reinforcement, protect and other effects, be a kind of widely used geosynthetics.
The advantages of non-woven geotextile is：1. good penetrability；2. good heat preservation performance；It is 3. flexible, resilient；4. without cloth Directionality；5. have a wide range of application, main function is the enhancing of engineering, isolation, anti-filter, draining, is widely used in water conservancy, highway, iron The fields such as road, protective layer of the geotextiles as geomembrane can be also used in seepage control project, make protection impervious barrier without damage；
The shortcomings that non-woven geotextile is：1. intensity and durability are poor compared with textile cloth；2. can not be clear as other clothes Wash；3. fiber arranges, so easily being split from right angle orientation in certain direction.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to now provide, a kind of intensity is high, is not easy de- yarn and can Ensure the warp knit composite earthwork cloth of the straight degree of yarn.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of warp knit composite earthwork cloth, its innovative point It is：Including woven nitride layer and nonwoven layer, the woven nitride layer is fixedly connected with nonwoven layer, the non-woven fabrics Layer is 120g/m2Ageing-resistant polypropylene chopped fiber non-woven fabrics, the woven nitride layer is high-strength ageing-resistant polypropylene fiber silk by woven The fabric made；
The woven nitride layer is made up of warp thread 1, weft yarn 2, binding silk 3 and binding silk 4, and the binding silk 3 and binding silk 4 pass through Specific structure is wrapped in the outer surface of warp thread and weft yarn.
Further, the knitted fabric by several square flower pattern constantly circulation form, the square flower pattern by Warp thread, weft yarn, binding silk 3 and binding silk 4 form by the weaving of specific structure.
Further, the woven nitride layer is formed by specific structure by constantly circulation, and the specific structure is：Adopt With 6 behavior, one circulation, the band yarn technique of the binding silk 4 is tied for 2-3,3-2,2-3,1-0,0-1,1-0 as a circulation Structure；The band yarn technique of the binding silk 3 is 1-0,0-1,1-0,2-3,3-2,2-3 as a loop structure；The warp thread Band yarn technique is 0-0,1-1 as a loop structure.
Further, the warp thread 1 is from 18000D high-strength ageing-resistant polypropylene fiber silk, height of the weft yarn 2 from 2000D Strong ageing-resistant polypropylene fiber silk, the binding silk 3 is from 222dtex dacron thread FDY, terylene of the binding silk 4 from 222dtex Silk FDY.
Beneficial effects of the present invention are as follows：The present invention realizes the friendship of binding 4 pairs of weft yarns of silk by using specific structure Fork binding, while silk 3 is bundled by using around bundling, the binding to warp thread is further enhanced, and by entering to weft yarn Row binding, realizes the together binding through weft yarn, and only intersection binding is carried out to warp thread compared to traditional handicraft, effective to improve Fixation to warp thread and weft yarn, avoids the slippage of weft yarn when in use, substantially increases the use intensity of the present invention, and The loop length of the present invention can realize change.

Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation Content disclosed by book understands other advantages and effect of the present invention easily.
As Figure 1-3, a kind of warp knit composite earthwork cloth, including woven nitride layer 5 and nonwoven layer 6, woven nitride layer 5 It is fixedly connected with nonwoven layer 6, nonwoven layer 6 is 120g/m2Ageing-resistant polypropylene chopped fiber non-woven fabrics, woven nitride layer 5 The fabric formed for high-strength ageing-resistant polypropylene fiber silk by warp knit weaving；
Woven nitride layer 5 is made up of warp thread 1, weft yarn 2, binding silk 4 and binding silk 3, and binding silk 4 and binding silk 3 pass through specific knot Structure is wrapped in the outer surface of warp thread and weft yarn.
Knitted fabric is formed by the constantly circulation of several square flower pattern, and square flower pattern is by warp thread 1, weft yarn 2, binding silk 4 form with binding silk 3 by the weaving of specific structure.
Woven nitride layer 5 is formed by specific structure by constantly circulation, and specific structure is：Using 6 behavior, one circulates, The band yarn technique for bundling silk 4 is 2-3,3-2,2-3,1-0,0-1,1-0 as a loop structure；Bundle the band yarn technique of silk 3 It is 1-0,0-1,1-0,2-3,3-2,2-3 as a loop structure；The band yarn technique of warp thread 1 is that 0-0,1-1 follow as one Ring structure.
Warp thread 1 is from 18000D high-strength ageing-resistant polypropylene fiber silk, and weft yarn 2 is from 2000D high-strength ageing-resistant polypropylene fiber silk, bundle Tie up dacron thread FDY of the silk 4 from 222dtex, dacron thread FDY of the binding silk 3 from 222dtex.
The present invention realizes the intersection binding of binding 3 pairs of weft yarns 2 of silk, while it is logical to bundle silk 4 by using specific structure Cross using around binding, further enhance the binding to warp thread 1, and by being bundled to weft yarn 2, realize through weft yarn Together binding, intersection binding only is carried out to warp thread 1 compared to traditional handicraft, effectively raised to warp thread 1 and weft yarn 2 It is fixed, the slippage of weft yarn 2 when in use is avoided, substantially increases the use intensity of the present invention, and the coil length of the present invention Degree can realize change.
Above-described embodiment is presently preferred embodiments of the present invention, is not the limitation to technical solution of the present invention, as long as The technical scheme that can be realized on the basis of above-described embodiment without creative work, it is regarded as falling into patent of the present invention Rights protection scope in.
