Description

Three-dimensional vegetation blanket

Technical field:

The invention relates to a planting mesh blanket used in soil and water conservation projects; in particular, it refers to a three-dimensional mesh blanket of a geometrically arranged mesh structure or mesh unit formed by weaving weft threads or warp threads.

Background technique:

It is a known technology to apply in soil and water conservation, slope, grass planting or related environmental protection projects to prevent soil from being directly washed and lost by rainwater. For example, China Taiwan Patent No. 90202432 "Strengthening One-piece Composite Grid Blanket", No. 92206580 "Continuous Wave-shaped Monofilament Anti-erosion Vegetative Net Blanket", No. 94214297 "Plant Net Cotton Structure", etc. Typical embodiments are disclosed. They reveal that a dense fiber layer made of coconut fiber, non-woven fabric or cotton is set between the upper and lower net layers, so that the flat plant net blanket has sufficient thickness and buffering effect to prevent rainwater from directly scouring the soil surface. , affecting the effect of water and soil conservation and greening and vegetation.

As those who are familiar with this technology know, the dense fiber layer has less porosity, so it is not conducive to the penetration of sunlight and provides enough growth space for vegetation and grass species to pass through and attach, so as to achieve the anchoring mesh blanket to form a stable The function of the stiffening surface; this situation has been proved from its products. Another factor that makes the grass vegetation produced by the known vegetation net blanket unsatisfactory may also include the non-stereoscopic structure of the surface of the upper and lower net layers, which has insufficient adhesion to the covering soil covered on it, and is easy to be washed away by rainwater.

In order to improve the non-stereoscopic structure of the upper and lower net layers and the lower porosity of the fiber layer of the known planting net blanket, the known technology has also disclosed a three-dimensional planting net blanket structure; for example, Fig. 1 and China Taiwan's No. 92209363 "Anti-Erosion Vegetation Three-dimensional Net" patent case and the like provide typical embodiments. They are made into multi-layered grids, and some areas of the grids are fused through a heating process, and one layer of the grids is formed into a wavy three-dimensional shape that is undulating or arranged. In order to maintain the three-dimensional wavy structure, this kind of vegetation grid or net blanket tends to be made of harder materials, such as yarn, PE, or plastic materials; therefore, it is relatively inelastic. Especially after they are heated and formed, the elasticity or deformation recovery force of the material is often minimized, and it becomes very inconvenient in the stage of rolling and transportation; for example, they have the problem of excessive rolling volume, in In the rolling and transporting stage, the three-dimensional structure of the wave shape is often destroyed due to compression or extrusion, resulting in defective products or unsatisfactory laying and planting effects; and this situation is not what we expect.

Typically, these reference data show the technology of the structure and application of the planting netting; they also reflect some problems in the structural design of the planting netting in some application situations. If redesign considers the organizational structure of the planting net blanket, making its structure different from the known technology, it will be able to change its use pattern, and be different from the old method; in essence, it will also increase its application range. But how to overcome or improve the above-mentioned issues we discussed? For example, make its structural design conform to a condition of easy construction, and at the same time have better elasticity or deformation recovery force, so as to reduce the situation that the known structure is not conducive to rolling and transportation and its derivatives; or further make the vegetation net The blanket can adjust the size of the porosity according to the topography or plant grass species, improve the growth of plant grass species and facilitate the absorption of fertilizers and sunlight, and improve the old methods such as the lack of ductility or poor ductility of the net blanket; we found that its The construction must take into account the following design issues:

1. It should be different from the structure and design direction of the above-mentioned patent case in which a fiber layer is interposed between the upper and lower grids or a heating process is applied to make the hard grid form a concave-convex wave shape; in order to reduce the porosity of the net blanket Small, not conducive to the growth of vegetation grass species.

2. The Figure 1 and the Taiwan Patent No. 92209363 "Anti-Erosion Vegetation Three-dimensional Net" should be discarded, and the heating process should be used to form a concave-convex and wavy net blanket structure; it is not conducive to the situation of net blanket rolling and transportation .

3. In order to maintain or increase the adhesion of the net blanket to the soil or covering soil, the vegetation net blanket should have better lateral or longitudinal stretching characteristics, forming a larger space for vegetation adjustment; and make the vegetation net blanket can be adjusted according to the terrain or vegetation. Grass species to adjust its structure type or porosity.

4. In particular, compared with the known ones, the structure of the vegetation net blanket should be re-arranged and designed so that it has better elasticity and thickness; even if it is compressed and transported, it is still easy to return to its three-dimensional structure.

None of these issues are taught or specifically disclosed in the above references.

Invention content:

The technical problem to be solved by the present invention is to provide a three-dimensional vegetation mesh blanket, which is easy to construct and convenient to curl and transport, and can improve the poor stretching or ductility in the prior art.

In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a three-dimensional planting network blanket, including a first layer of fabric, a second layer of fabric, and a height part, and the height part is connected between the first layer of fabric and the second layer of fabric. Between layers of fabrics; the first and second layers of fabrics respectively have several mesh units and several connection points, and the first layer of fabrics and the second layer of fabrics are respectively composed of at least one first line unit weaving, which is characterized by: The first thread unit defines a weft thread and a warp thread, and the weft thread weaves to constitute the first layer of fabric and the second layer of fabric; the warp thread is connected between the first layer of fabric and the second layer of fabric to form the height portion.

The first layer of fabric and a second layer of fabric include at least one first line unit (or defined as weft), which is formed by weaving the first line unit in a horizontal reference direction; and has at least one first line unit (or Defined as a warp) is connected between the first and second layers of fabric in a vertical reference direction to form a height portion (or linear structure). The weft is interwoven with several connection points on the first and second layers of fabrics, so that the first and second layers of fabrics have mesh units similar to arrays, providing the conditions for grass seed rhizomes to easily pass through, attach and grow, and increase the rooting of plants. and survival rate; moreover, the mesh unit allows the planting net blanket to be stretched and extended to form a larger vegetation accommodation space when in use, and can fully adjust the covering surface of the net blanket according to terrain changes, forming a better lamination state with the soil and so on.

According to the three-dimensional planting net blanket of the present invention, the weft weaving forms several continuous loops, each loop is connected to each other and extends toward a horizontal reference direction defined by an x-axis and a y-axis to form the first layer of fabric or Second layer of fabric. Thus, each loop allows the first layer of fabric or the second layer of fabric to be stretched along the x-axis or y-axis.

According to the three-dimensional planting net blanket of the present invention, after the weft thread is selectively woven to form several loops, at least one loop will be connected with the adjacent row of loops to form a connection point.

According to the three-dimensional planting mesh blanket of the present invention, the warp thread connects the loops of the first layer of fabric and the second layer of fabric in a vertical reference direction defined by a z-axis to form the height portion (or linear structure). The height part makes the first layer of fabric and the second layer of fabric also have an elastic supporting effect, so that the first layer of fabric and the second layer of fabric are allowed to be squeezed or compressed, and the vegetation net can also be The blanket is improved and restored to its original three-dimensional form. In addition, it provides vegetation and grass species to pass through and attach space.

According to the three-dimensional planting net blanket of the present invention, the first line unit is respectively defined with weft and warp parts; After the first loop of fabric, extend along the z-axis towards the direction of the second fabric to form the height portion (defined as warp); and, after weaving the first loop forming the second fabric , and then extend back to the first layer of fabric along the z-axis, weave the second loop of the first layer of fabric, and wear and connect with the first loop of the first layer. Then, make the first line unit extend to the second layer of fabric along the z-axis, weave the second loop of the second layer of fabric, and wear and connect with the first loop of the second layer.

According to the three-dimensional planting network blanket of the present invention, the connection point of the first layer of fabric is above the mesh unit of the second layer of fabric; the connection point of the second layer of fabric is below the mesh unit of the first layer of fabric , so that the positions of the joint points of the first layer of fabric and the positions of the joint points of the second layer of fabric form a staggered or staggered pattern that does not correspond to the upper and lower sides. The structure structure also has the better three-dimensional support effect of the old method, so that the first and second layers of fabrics will not produce the three-dimensional structure of the known net blanket when the vegetation spraying and soil covering operations are carried out. crushed situation.

In this way, the structural organization of the present invention has better elastic support or deformation recovery force than the known ones; even if it is compressed and rolled up, it is still easy to restore its three-dimensional structure; Grass species to adjust the size of the mesh unit or porosity, improve the growth of vegetation grass species and facilitate the absorption of fertilizers and sunlight; and maintain or increase the adhesion effect of the net blanket to the soil or covering soil; and have better lateral or Longitudinal stretching and extension characteristics are used to establish a larger space adjustment mechanism than known net blankets for the implementation of grass planting and soil covering operations.

The novelty, characteristics, and other purposes and effects of the present invention will be explained in detail below in conjunction with the attached drawings, and tend to be understood; as shown in the figure:

Detailed ways:

Referring to Fig. 2, Fig. 3 and Fig. 4, the present invention is a three-dimensional planting net blanket, comprising a first layer of fabric and a second layer of fabric, which are represented by reference numerals 10 and 20 respectively; said first layer of fabric 10 and There is a height portion h (or called linear structure) between the second layer of fabrics 20, and the first layer of fabric 10 and the second layer of fabric 20 are composed of several mesh units 11, 21 respectively. In the adopted embodiment, we define that the first layer of fabric 10 is on a reference plane (or called a horizontal reference direction) defined by an x-axis and a y-axis; the second layer of fabric 20 is on an x ' axis and a y' axis define a reference plane (or called a horizontal reference direction), and the height part h is located in a z axis defined reference direction (or called a vertical reference direction). Meanwhile, in FIG. 4 , in order to show the relational position between the first layer of fabric 10 and the second layer of fabric 20 , the first layer of fabric 10 is depicted with thick lines, and the second layer of fabric 20 is depicted with thin lines.

The first layer of fabric 10 and the second layer of fabric 20 are formed by weaving at least one first thread unit 30 (or defined as a weft thread) on the reference plane defined by the x-y axis and the x'-y' axis. In a feasible embodiment, the first line unit 30 is defined with a warp 30a, which is connected between the first layer of fabric 10 and the second layer of fabric 20 to form the height portion h; specifically, each warp 30a uses The height part h forms a linear weave pattern, and together with the first and second layers of fabrics 10, 20, a three-dimensional mesh blanket with an ideal spatial structure pattern is established. In a modified embodiment, the height part h can also be formed by the second line unit 40 (this part will be described below). The height part h makes the first layer of fabric 10 and the second layer of fabric 20 also have an elastic support function on the z axis or the vertical reference direction, so that the first layer of fabric 10 and the second layer of fabric 20 are allowed to be squeezed Pressing or compressing can also make the improved vegetation net blanket return to its original three-dimensional shape after the pressing or compressing is released. In addition, it provides a space for vegetation and grass to pass through and attach. In a feasible embodiment, the first and second wire units 30, 40 tend to be made of yarn, PE, HDPE, plastic or other flexible materials.

The first line unit 30 (or weft) is woven with several connection points 12,22 on the first layer of fabric 10 and the second layer of fabric 20 respectively, so that the first and second layer of fabrics 10,20 have a similar array or honeycomb arrangement Types of mesh units 11,21.

Please refer to Fig. 5 and Fig. 6, depicting the situation that the first and second layers of fabrics 10, 20 are stretched; at the same time, in Fig. 6, in order to show the relationship between the first layer of fabric 10 and the second layer of fabric 20 In particular, the first layer of fabric 10 is depicted with thick lines, while the second layer of fabric 20 is depicted with thin lines. The mesh unit 11, 21 allows the planting net blanket formed by the first and second layers of fabrics 10, 20 to be stretched along the x, x' axis or y, y' axis to form a larger planting space and can be adjusted according to the terrain. Change and adjust the net blanket to cover the ground to form a better fit with the soil; moreover, it makes the grass species easy to receive sunlight, pass through attachment and grow, and increase the rooting of plants. In the embodiment adopted in the present invention, the mesh units 11, 21 form a geometric shape or outline; Fig. 4 and Fig. 6 particularly depict the situation where the mesh units 11, 21 form a rhombus-like or rectangular outline.

In the adopted embodiment, the first thread units 30 (or weft threads) of the first layer of fabric 10 and the second layer of fabric 20 are woven on the reference plane defined by the x-y axis and the x'-y' axis to form a A plurality of continuous rings 30b, each ring 30b is connected to each other, and extends towards the reference direction defined by the x-y axis and the x'-y' axis respectively, to form the first layer of fabric 10 and the second layer of fabric 20 . At the same time, after the first line unit 30 is braided to form several loops 30b, at least one loop (indicated by number 30c) will be selectively connected with the adjacent row of loops (indicated by number 30d) to form the connecting point 12 ,twenty two. In the adopted embodiment, after the first thread unit 30 is weaved until about the 10th loop, the loop 30c is threadedly connected to the adjacent row of loops 30d or connected by heating to form the connecting point 12 ,twenty two.

Therefore, in a preferred consideration, the first layer of fabric 10 or the second layer of fabric 20 includes the following design considerations:

1. The size or specification of each ring 30b can be woven according to the site environmental conditions or requirements, so that each ring 30b forms a tight wear-and-fit connection; or each ring 30b has an activity margin, so that the first The first layer of fabric 10 and the second layer of fabric 20 have the function of allowing stretching along the x, x' axis or y, y' axis.

2. Selecting the distance of each connecting point 12, 22 weaved by the first line unit 30 can determine the size or specification of the mesh unit 11, 21, and provide the operator with the grass species or site environment requirements; The first layer of fabric 10 and the second layer of fabric 20 have stretching effects of different sizes, so as to form a larger effect of adjusting the vegetation accommodation space. For example, if the first line unit 30 is selected to form a connection point after weaving the 15th ring, the area of the mesh unit established by it is greater than the area of the mesh unit established by the first line unit 30 when weaving the 5th ring. ; Relatively, the larger the mesh unit 11, 21, the greater the stretchability of the first layer of fabric 10 or the second layer of fabric 20.

In a feasible embodiment, the weaving path of the first thread unit 30 at least includes: weaving (defined as weft threads) in the horizontal reference direction defined by the x-axis or y-axis to form the first layer of fabric 10 After loop 30b, extend along the direction of the second layer of fabric 20 defined by the x' axis or y' axis along the z axis to form the height portion h (defined as warp 30a); After the first loop 30b of the layer fabric 20, extend back to the first layer fabric 10 along the z axis, weave the second loop 30b of the first layer fabric 10, and with the first loop 30b of the first layer fabric 10 The rings 30b are threaded and connected to each other. Then, make the first line unit 30 extend to the second layer of fabric 20 along the z axis, weave the second loop 30b of the second layer of fabric 20, and pass through each other with the first loop 30b of the second layer of fabric 20 combined connection.

In a modified embodiment, the first line unit 30 is braided on the reference plane defined by the x-y axis and the x'-y' axis to form the first layer of fabric 10 and the second layer of fabric 20; and as above As mentioned above, at least one second line unit 40 is provided to pass through the first ring 30b of the first layer of fabric 10, and then extend along the z-axis toward the direction of the second layer of fabric 20 to form the height portion h; and, when wearing After closing and connecting the first loop 30b of the second layer of fabric 20, it extends back to the first layer of fabric 10 along the z-axis, and wears and closes the second loop 30b of connecting the first layer of fabric 10. In the embodiment taken, the diameter of the second wire unit 40 is larger than the diameter of the first wire unit 30 .

It can be understood that the above-mentioned first line unit 30 or second line unit 40 weaves the planting mesh blanket composed of the first layer of fabric 10, the second layer of fabric 20 and the height part h, etc., which can be completed by special machine weaving.

Please refer to Fig. 4 and Fig. 6 again, in a preferred consideration, the joint point 12 of this first layer of fabric 10 is positioned at the top of the mesh unit 21 of second layer of fabric 20; The points 22 are located below the mesh units 11 of the first layer of fabric 10 , so that the positions of the connection points 12 of the first layer of fabric 10 and the positions of the connection points 22 of the second layer of fabric 20 form a non-corresponding interlaced or staggered pattern. Therefore, each connecting point 12, 22 is jointly supported by a linear tissue composed of several warp threads 30a or second thread units 40 at four positions on the z axis, thereby providing the first layer of fabric 10 and the second layer The fabric 20 has a better spatial structure, good supporting capacity and the function of elastic recovery force. In other words, the structure organization type has a better three-dimensional support than the old method, so that the first and second layers of fabrics 10, 20 will not produce a three-dimensional structure like the known net blanket when implementing vegetation spraying and soil covering operations. Situations where patterns are easily crushed. Moreover, the gaps established between each warp line 30a or the second line unit 40 also provide the function of the vegetation grass species to pass through, attach and grow, and increase the rooting ability of the vegetation.

Please refer to Fig. 7, between the first layer of fabric 10, the second layer of fabric 20, the height part h and each mesh unit 11, 21, it is allowed to be stretched and expanded or compressed to fit each other to reduce the volume and space, and has elastic resilience. Therefore, this vegetation net blanket is also particularly suitable for the stage of rolling and transportation; so that it will not damage the original design structure when rolling and unfolding, so as to meet the needs of convenient transportation and engineering use. As in the old method, the damage to the three-dimensional structure of the net blanket due to compression and curling is minimized as much as possible.

Typically, the three-dimensional vegetation net blanket includes the following design considerations under the condition of providing an easy construction:

1. Compared with known objects, its structural organization has been rearranged and designed, so that it has better elastic support or deformation recovery force; even if it is compressed and transported, it is still easy to return to its three-dimensional structure; It can reduce the situation that the known structure is unfavorable for rolling and transporting and its derivatives.

2. Its structural design is different from the structural organization and design direction of the above-mentioned patent case in which a fiber layer is interposed between the upper and lower grids or a heating process is applied to make the hard grid form a concave-convex wave shape; The blanket can also adjust the size of the mesh unit 11, 21 or porosity according to the topography or the vegetation grass species, so as to improve the growth of the vegetation grass species and the absorption of fertilizer and sunlight; Attachment effect. And have better lateral or longitudinal tensile extension characteristics, to establish a larger space adjustment mechanism than the known net blanket, for the implementation of grass planting and soil covering operations; and, its structural organization has improved the net blanket in the old method No ductility or poor ductility, etc.
