Description

Technical Field

[0001] This utility model relates to the field of geotextile technology, and in particular to a multi-layer composite geotextile. Background Technology

[0002] Geotextile, also known as geotextile fabric, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile is one type of new geosynthetic material, and the finished product is in the form of cloth, divided into woven geotextile and non-woven filament geotextile.

[0003] In existing water conservancy and building construction processes, when laying geotextiles, multiple geotextiles are laid side by side, with the geotextile covering one side of the adjacent geotextile or being covered under the adjacent geotextile. The friction between the two geotextiles is used to avoid misalignment after covering. However, this method is suitable for flat land, but not for some slope protection.

[0004] Therefore, this application provides a multilayer composite geotextile to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-layer composite geotextile that can be quickly spliced, connected, and positioned for installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-layer composite geotextile includes a geotextile body, a first connecting block fixedly disposed at the front end of the geotextile body, a second connecting block fixedly disposed at the rear end of the geotextile body, and multiple anti-slip strips fixedly disposed on the lower end face of the geotextile body. The first connecting block and the second connecting block are spliced ​​together to complete the connection of two adjacent geotextile bodies.

[0008] Furthermore, the first connecting block includes a first block body, a stop strip is fixedly installed at the midpoint of the lower end face of the first block body, and a first Velcro fastener is fixedly installed on both sides of the front end face of the stop strip. Multiple first connecting holes are opened through the upper end face of the first block body, and a first thickened cloth ring is fixedly installed at the upper and lower ends of the inner walls of the multiple first connecting holes.

[0009] Furthermore, the second connecting block includes a second block body, which has an L-shaped structure and the upper end of the bent end is inclined at the corner to form a water channel. The second block body has two Velcro fasteners fixedly installed on both sides of the rear end face. The second block body has multiple second connecting holes through the inclined surface at the upper end, and the upper and lower ends of the inner walls of the multiple second connecting holes are fixedly installed with second thickened cloth rings.

[0010] Furthermore, the geotextile body includes a base layer, an abrasion-resistant layer is provided on the outer side of the base layer, and an anti-corrosion layer is provided at the lower end of the base layer.

[0011] Furthermore, the outer wall of one side of the two outermost antislip strips located on both sides of the plurality of antislip strips is on the same plane as the outer walls of both sides of the geotextile body.

[0012] This utility model has the following beneficial effects:

[0013] This utility model proposes a multi-layer composite geotextile. By setting a No. 1 connecting block and a No. 2 connecting block at the front and rear ends of the geotextile body, when two adjacent geotextile bodies are laid, the No. 1 connecting block and the No. 2 connecting block at the front and rear ends can be spliced ​​together to achieve the combination of two adjacent geotextiles. After combination, there is no large gap on the upper surface, and when water flows down along the gap, it will be discharged to both sides along the water channel, thereby reducing the problem of water falling into the lower end of the geotextile and causing damage. At the same time, the No. 1 connecting block and the No. 2 connecting block at the front and rear ends can be used to achieve the effect of quick positioning and installation with screws through the opening of the connection hole, and the thickened cloth ring added inside the connection hole can improve the tensile strength of the connection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-5 The present invention provides an embodiment of a multi-layer composite geotextile, comprising a geotextile body 2, a first connecting block 1 fixedly disposed at the front end of the geotextile body 2, a second connecting block 3 fixedly disposed at the rear end of the geotextile body 2, and multiple anti-slip strips 4 fixedly disposed on the lower end face of the geotextile body 2. The first connecting block 1 and the second connecting block 3 are spliced ​​together to complete the connection of two adjacent geotextile bodies 2.

[0023] Specifically, when it is necessary to splice and lay two adjacent geotextile bodies 2, the splicing can be completed by combining and splicing the No. 1 connecting block 1 and the No. 2 connecting block 3 at the beginning and end of the two adjacent geotextile bodies 2, and then binding them by passing hemp rope or screw through the corresponding connecting holes or directly positioning them on the ground. At the same time, the anti-slip strip 4 set at the lower end can reduce the problem of accidental slippage.

[0024] Reference Figures 1-3 The first connecting block 1 includes a first block body 104. A baffle 102 is fixedly installed at the midpoint of the lower end face of the first block body 104. A first hook and loop fastener 105 is fixedly installed on both sides of the front end face of the baffle 102. Multiple first connecting holes 103 are opened through the upper end face of the first block body 104. A first thickened cloth ring 101 is fixedly installed at the upper and lower ends of the inner walls of the multiple first connecting holes 103. The second connecting block 3 includes a second block body 301. The second block body 301 adopts an L-shaped structure and the upper end face of the bent end is inclined at the corner to form a water channel 305. A second hook and loop fastener 302 is fixedly installed on both sides of the rear end face of the second block body 301. Multiple second connecting holes 304 are opened through the inclined upper end face of the second block body 301, and a second thickened cloth ring 303 is fixedly installed at the upper and lower ends of the inner walls of the multiple second connecting holes 304.

[0025] Specifically, when assembling connecting block 1 and connecting block 3, block 104 is placed on the inclined surface of block 301, and multiple connecting holes 103 and 304 are aligned vertically. Screws are then passed through the aligned connecting holes to nail it to the ground for positioning and installation. At the same time, when placing block 104 on the inclined surface of block 301, Velcro 105 and Velcro 302 are glued and fixed to assist in fixing it. After assembling connecting block 1 and connecting block 3, a seam will be formed at the joint point on the upper end. Water seeping into the seam will collect in the water channel 305 on the inclined surface to guide and drain outwards.

[0026] Reference Figure 5 The geotextile body 2 includes a base layer 202, a wear-resistant layer 201 is provided on the outside of the base layer 202, and an anti-corrosion layer 203 is provided at the lower end of the base layer 202.

[0027] Specifically, the wear-resistant layer 201, the base layer 202, and the anti-corrosion layer 203 are bonded together with an adhesive; the wear-resistant layer 201 is made of polypropylene resin or polyurethane resin. The wear-resistant layer 201 is manufactured using a non-woven polypropylene resin; the anti-corrosion layer 203 is made of methacrylic anhydride resin or epoxy resin. The anti-corrosion layer 203 is manufactured using a non-woven methacrylic anhydride resin.

[0028] Reference Figures 3-4 Among the multiple anti-slip strips 4, the outer wall of one side of the two anti-slip strips 4 located at the outermost edges on both sides is on the same plane as the outer walls of both sides of the geotextile body 2; by setting the anti-slip strips 4 to the outermost side, water can be prevented from sliding down and flowing under the geotextile, thus playing an auxiliary and obstructive role.

[0029] Working principle: When two adjacent geotextile bodies 2 need to be spliced ​​and laid, the first connecting block 1 and the second connecting block 3 at the beginning and end of the two adjacent geotextile bodies 2 are combined and spliced; the first block 104 is placed on the inclined surface of the second block 301 and the multiple first connecting holes 103 and second connecting holes 304 are aligned vertically. Then, screws can be used to pass through the vertically aligned connecting holes to nail it to the ground to complete the positioning and installation. At the same time, when the first block 104 is placed on the inclined surface of the second block 301, the first hook and loop fastener 105 and the second hook and loop fastener 302 are glued and fixed to achieve the auxiliary fixing effect. After the first connecting block 1 and the second connecting block 3 are spliced ​​and combined, a connecting seam will be formed at the joint point on the upper end. The water that seeps into the connecting seam will be collected in the water channel 305 on the inclined surface to achieve the effect of guiding and draining outward.

[0030] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
