Description

Technical Field

[0001] The invention relates to the technical field of geotextiles, in particular to a high-toughness, water-conducting and ultra-strong woven geotextile. Background Art

[0002] Geotextile, also known as woven geotextile, is generally used for the reinforcement and enhancement of geotechnical engineering projects (such as soil and water conservation and ecological restoration projects in rivers and embankments). It has plane isolation and protection functions and is a material frequently used in modern ecological engineering.

[0003] Typical geotextiles in the prior art include authorization number CN107190416B, a method for preparing geotextiles, and belonging to the field of geosynthetics. The present invention melt-extrudes polypropylene, tetramethyl divinyl disiloxane and an initiator to obtain an extrudate, cools the extrudate to obtain silicone-modified polypropylene, stirs and reacts with polyethylene terephthalate fiber monofilaments, and then filters to obtain modified polyethylene terephthalate fibers, and then mixes with a binder, an antioxidant and water, and then filters to obtain a filter cake, freeze-dries the filter cake to obtain a dried product, and spreads the dried product on a mesh curtain of a mesh machine, and after the oblique curtain is reciprocated, it is consolidated by a needle punching machine to obtain a geotextile.

[0004] Existing geotextiles have excellent filtering, isolation, reinforcement and protection functions when used, and have high tensile strength. However, conventional geotextiles often have some problems during use. Poor water absorption and water conduction effects will cause soil moisture loss and collapse, and water accumulation is prone to occur when there is too much water. Summary of the invention

[0005] The purpose of the present invention is to provide a high-toughness, water-conducting and extra-strong woven geotextile to solve the problem that the existing geotextile proposed in the above background technology has excellent filtering, isolation, reinforcement and protection functions when used, and has high tensile strength. However, conventional geotextiles often have some problems during use. The poor water absorption and water conduction effect will lead to soil moisture loss and collapse, and water accumulation is prone to occur when there is too much water.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-tenacity water-conductive and extra-strong woven geotextile, comprising high-strength polyester fibers and carbon fibers, wherein the high-strength polyester fibers and carbon fibers are woven with each other in warp and weft, the warp direction is composed of four thousand to ten thousand high-strength polyester fibers and extra-strong heat-absorbing carbon fibers, and there are two to fifty or more heat-absorbing carbon fiber components in every one hundred high-strength polyester fibers, and the weft direction is woven from 10000D to 20000D high-strength polyester fibers, and a sealing frame is fixed to the edge of the high-strength polyester fibers and carbon fibers, and a splicing frame is fixed to the outside of the sealing frame.

[0007] An annular groove is provided on the upper end surface of the splicing frame, water-absorbing cotton is clamped in the annular groove, a spring is fixed in the water-absorbing cotton, and a second drainage hole is provided at the bottom of the splicing frame.

[0008] Preferably, the entire surface of the high-strength polyester fiber is sprayed with an anti-oxidation coating, and the material used for the anti-oxidation coating is a boron nitride coating.

[0009] By adopting the above technical solution, the use of the anti-oxidation coating can effectively prevent the surface of the high-strength polyester fiber from being oxidized, thereby causing the use strength to decrease.

[0010] Preferably, the splicing frame is provided with clamping holes, and the clamping holes are evenly distributed on the splicing frame in a circumferential direction.

[0011] By adopting the above technical solution, two splicing frames on the device can be spliced ​​together by using the clamping holes and clamping columns.

[0012] Preferably, a clamping column is fixed to the upper end surface of the splicing frame, and a first drainage hole is opened on the clamping column, and the clamping column is evenly distributed on the splicing frame in a circumferential direction.

[0013] By adopting the above technical solution, the circumferentially evenly distributed clamping holes and clamping columns can make the splicing and assembly effect more compact and firm.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The high-tenacity water-conducting and super-strong woven geotextile can achieve the purpose of water conduction through the mutual use of high-strength polyester fibers and carbon fibers. The high-tenacity water-conducting and super-strong woven geotextile is composed of warp high-strength polyester fibers and 12k24k carbon fibers. The warp is composed of 4,000 to 10,000 high-strength polyester fibers and super-strong heat-absorbing carbon fibers. There are two to fifty or more heat-absorbing carbon fibers in every 100 high-strength polyester fibers, which is convenient for thawing frozen soil and conducting water to discharge water faster. The weft is woven with 10000D to 20000D high-strength polyester fibers, which is convenient for increasing the strength of the product and making the product more stable and faster in heat and water conduction. 2. The high-toughness water-conducting and super-strong woven geotextile can achieve the purpose of convenient splicing through the coordinated use of the splicing frame, the clamping hole and the clamping column. When another device is buckled upside down on the edge of the device, the clamping column is clamped into the clamping hole, so that the splicing frames on the two devices are spliced ​​together. The front, back, left and right of the device can be spliced ​​with another device. The entire splicing size can be adjusted automatically, and it is highly flexible. 3. The high-toughness, water-conducting and super-strong woven geotextile can achieve the purpose of absorbing water and draining water through the coordinated use of the sealing frame, the first drainage hole, the annular groove, the absorbent cotton and the second drainage hole. The water guided out from the sealing frame will enter the annular groove and will be absorbed by the absorbent cotton. The absorbent cotton will squeeze out the water after being squeezed. The first drainage hole and the second drainage hole can be used to drain water, thereby ensuring the water-conducting and drainage effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS
