Description

Technical Field

[0001] The utility model relates to the technical field of protective nets, in particular to a soil and water loss protective net. Background Art

[0002] Soil erosion refers to the phenomenon that due to the influence of natural or human factors, rainwater cannot be absorbed on the spot, flows down and washes the soil, causing the loss of water and soil at the same time. At present, methods such as laying protective nets and transplanting vegetation are often used to protect the surfaces of slopes, river banks, channels and other areas from rainwater erosion, improve the stability of soft soil base, prevent soil erosion, and thus protect the overall stability. The patent document with application number CN202223262557.1 discloses a soil erosion protection net for protecting plant growth, which is composed of a plurality of rectangular grids combined in an array, and the bottom side of the rectangular grid itself is provided with spikes. Therefore, when in use, the bottom side of the soil erosion protection net can be directly pressed into the soil. The spikes on each rectangular grid will be inserted into the soil to ensure the reliable installation of the soil erosion protection net on the land. However, the spikes on the rectangular grid have a simple structure and are easily detached from the soil under the action of external force. The fixing effect is poor, and there is a gap between it and the soft soil base, which cannot fit tightly, affecting the protection effect.

[0003] The patent document with application number CN202021958522.X discloses a composite geonet. This composite geonet uses geogrids to fix the position of the three-dimensional geonet, and the geogrids and the three-dimensional geonet can jointly fix the soil to reduce the force exerted by the soil on the three-dimensional geonet due to displacement, thereby ensuring the structural integrity of the three-dimensional geonet. The composite geonet can be applied to higher slopes to provide effective protection for the slopes and prevent soil erosion. However, after laying, the geonet does not have fixing parts that are firmly connected to the soil, and the tensile effect is low. Utility Model Content

[0004] In order to solve the technical problems of low strength and poor fixing effect existing in the above background technology, the utility model provides a soil and water loss protection net.

[0005] The technical solution of this utility model is as follows:

[0006] A soil and water loss protection net includes a net body, the net body includes a plurality of woven strips arranged in a criss-cross grid shape, and the net body is connected to a fixing piece; the fixing piece includes a connecting piece movably connected to the woven strips, and the connecting piece is provided with a soil locking nail perpendicular to the plane of the net body; the soil locking nail is provided with a plurality of barbs arranged along its length, and the soil locking nail is provided with a strip-shaped through hole that passes through both sides of the soil locking nail and is opened along its length.

[0007] The net body and the fixing parts are movably connected, and the net body and the fixing parts can be stored and transported separately. The soil locking nails and the net body are connected into a whole through the connecting parts to improve the overall stability. At the same time, barbs are provided around the soil locking nails, which makes it difficult to pull out the soil locking nails after inserting them into the ground, thereby improving the overall tensile strength of the protective net. In addition, through holes are provided on the soil locking nails, and plant roots can grow through the through holes, which does not hinder plant growth and can also strengthen the connection between the protective net and the plant roots, further enhancing the overall fixing effect.

[0008] The connector structure consists of a circular connecting plate with a number of fixing straps on its outer ring that can be flexibly connected to the braided strips. The soil-locking nails are installed perpendicularly on one side of the connecting plate. The connecting plate not only connects to the braided strips via the fixing straps, but also secures the soil-locking nails, improving the integrity between the soil-locking nails and the mesh.

[0009] Specifically, the soil-locking nail comprises several vertically arranged strips arranged circumferentially along a vertical axis. Each of these strips is provided with strip-shaped through-holes extending along its length and extending along its sides. At least four of these strips are arranged in a cross-shaped pattern, ensuring consistent strength in all directions. This allows plant roots in the soil to grow through the holes, allowing them to intertwine and weave through them without affecting plant growth while enhancing the nail's effectiveness.

[0010] As a preferred embodiment, one end of the plurality of fixing straps is connected to the connecting plate and is arranged to be retracted parallel to the length direction of the soil locking nail. When transporting the soil locking nail, the fixing straps can be retracted to one side of the soil locking nail, saving transportation space and facilitating its movement and transportation.

[0011] Furthermore, the end of the soil-locking nail facing away from the connecting piece is in a pointed cone shape, which makes it easy to insert the soil-locking nail into the soil, saving time and effort.

[0012] Preferably, the plurality of braided strips are arranged in an equidistant array along the longitudinal and transverse directions to ensure the performance consistency of the mesh in the longitudinal and transverse directions.

[0013] As a preferred embodiment, the surface of the mesh is coated with a special green resin glue, which has the properties of being waterproof, oil-resistant, and resistant to strong acids and alkalis, thereby improving the strength of the mesh and enhancing its durability. The green coating can make the mesh consistent with the environmental color of protected land such as slopes and river embankments.

[0014] Further preferably, the mesh body adopts industrial high-strength, high-modulus, low-shrinkage twisted polyester yarn, which has good moisture resistance and can maintain its strength after being damp, and has the characteristics of high strength, low elongation, high modulus, good dimensional stability and heat resistance stability. It can also adapt to different slopes or uneven slopes and can fit tightly with soft soil base.

[0015] Through the above-mentioned design, the beneficial effects of the soil erosion protection net of the present invention are as follows: the net body and the fixing parts are movably connected, and the net body and the fixing parts can be stored and transported separately; the soil locking nails are provided with barbs around the ring, making it difficult to pull out the soil locking nails after they are inserted into the ground, thereby improving the overall tensile strength of the protection net. In addition, the arrangement of several strip-shaped through holes on the soil locking nails allows the roots of plants to grow through the several through holes. The roots are intertwined and shuttle through the several through holes, which can not only ensure the growth of plants but also enhance the fixing effect of the soil locking nails. The soil locking nails are connected to the net body as a whole through the connecting parts, thereby improving the overall stability. The present invention has a good stabilizing effect on slopes, channels, river banks, slopes and other locations, and can effectively improve the stability of soft soil base surfaces and prevent soil erosion.

[0022] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0023] Example

[0024] Combine Figures 1 to 3 This embodiment provides a soil and water loss protection net, including a net body 1, wherein the net body 1 includes a plurality of woven strips 11 arranged in a crisscross grid shape.

[0025] Preferably, the plurality of braided strips 11 are arranged in an equidistant array along the longitudinal and transverse directions to ensure the performance consistency of the mesh body 1 in the longitudinal and transverse directions.

[0026] As a preferred embodiment, the surface of the mesh 1 is coated with a special green resin glue, which has the properties of being waterproof, oil-resistant, and resistant to strong acids and alkalis, thereby improving the strength of the mesh 1 and enhancing its durability. The green coating can make the mesh 1 consistent with the environmental color tone of protective land such as slopes and river embankments.

[0027] Further preferably, the mesh body 1 adopts industrial high-strength, high-modulus, low-shrinkage twisted polyester yarn, which has good moisture resistance and can maintain its strength after being damp. It also has the characteristics of high strength, low elongation, high modulus, good dimensional stability and heat resistance. It can adapt to different slopes or uneven slopes and can fit tightly with soft soil base.

[0028] In this embodiment, combined with Figure 1 The net body 1 is connected to a fixing part 2, and the fixing part 2 includes a connecting part 21 movably connected to the braided strip 11, on which a soil locking nail 22 perpendicular to the plane where the net body 1 is located is provided.

[0029] In practice, the fixing member 2 can be positioned anywhere on the net body 1 as needed. Multiple fixing members 2 can be provided, and they can be centrally or dispersedly arranged as needed, providing high flexibility and adaptability to different protection situations. The net body 1 and fixing member 2 are movably connected, allowing for separate loading and unloading. The net body 1 can be rolled up for transportation, while the fixing member 2 can be transported separately, saving transportation space, time, and effort. The soil locking nails 22 are integrally connected to the net body 1 via connectors 21, enhancing overall stability.

[0030] Combine Figure 2 Regarding the structure of the connector 21, it comprises a circular connecting plate 211, the outer ring of which is provided with a plurality of fixing straps 212 that can be flexibly connected to the braided strips 11. The soil-locking nails 22 are perpendicularly arranged on one side of the connecting plate 211. The connecting plate 211 not only connects to the braided strips 11 via the fixing straps 212, but also secures the soil-locking nails 22, thus improving the integrity between the soil-locking nails 22 and the net body 1.

[0031] As a preferred embodiment, one end of the plurality of fixing straps 212 is connected to the connecting plate 211 and is configured to be retractable parallel to the length direction of the soil locking nail 22. When transporting the soil locking nail 22, the fixing straps 212 can be retracted to one side of the soil locking nail 22, saving transportation space and facilitating its movement and transportation.

[0032] Combine Figure 3 In a specific implementation, at least four connecting holes are evenly distributed along the circumference of the connecting plate 211. One end of the fixing belt 212 is hung in the connecting hole, and the other end is set as a "Y" opening, and the braided strip 11 can be fixed in the opening. The end of the fixing belt 212 away from the connecting plate 211 is also provided with a locking hole 213 perpendicular to the length direction of the fixing belt 212, and the locking hole 213 is provided with a fastening bolt that can lock the opening closed.

[0033] Furthermore, the fixing belt 212 is made of high-strength polyester fiber material, which has high tensile strength and wear resistance, good durability, and can adapt to protection conditions of different slopes.

[0034] In practice, the soil-locking nail 22 is positioned in the middle of the connecting plate 211 to ensure that, once inserted into the ground, the nail 22 uniformly tightens the fixing straps 212 in all directions. The nail 22 is provided with a plurality of barbs arranged along its length. The nail 22 is also provided with strip-shaped through-holes 222 extending through both sides and along its length. The barbs make the nail 22 difficult to remove once inserted into the ground, thereby increasing the overall tensile strength of the protective net.

[0035] Specifically, the soil-locking nail 22 comprises several vertically arranged strips 221 arranged circumferentially along the vertical axis. Each of these strips 221 is provided with strip-shaped through-holes 222 extending along its length and extending along its sides. At least four strips 221 are arranged in a cross-shaped pattern, ensuring consistent strength in all directions. Plant roots in the soil can grow through these through-holes 222, allowing them to intertwine and weave through them without affecting plant growth while enhancing the securing effect of the soil-locking nail 22.

[0036] The two oppositely arranged strips 221 have a plurality of barbs arranged in the gaps along their length direction on the opposite sides thereof, and the plant roots can grow and extend continuously through the gaps between the barbs. The plant roots can continuously shuttle through the gaps between the through holes 222 and the barbs, so that the huge root system of the plant is connected to the protective net to form an integral structure, thereby increasing the tensile strength and shear strength of the protective net.

[0037] Furthermore, the end of the soil-locking nail 22 away from the connecting piece 21 is in a pointed cone shape, which makes it easy to insert the soil-locking nail 22 into the soil, saving time and effort.

[0038] The present invention comprises a mesh body 1 and a fixing member 2 that are movably connected, allowing the mesh body 1 and the fixing member 2 to be stored and transported separately. The soil-locking nails 22 are provided with barbs around their perimeter, making them difficult to remove once inserted into the soil, thereby increasing the overall tensile strength of the protective net. Furthermore, the plurality of strip-shaped through-holes 222 on the soil-locking nails 22 allow plant roots to grow through the plurality of through-holes 222. The intertwined root systems of the plants weave through the plurality of through-holes 222, connecting the large root systems of the plants with the protective net to form a single, integrated structure, thereby increasing the tensile and shear strength of the protective net. The present invention has an excellent stabilizing effect on slopes, channels, riverbanks, and side slopes, effectively improving the stability of soft soil bases and preventing soil erosion. The detachable structure facilitates overall transportation and movement, saving manpower and improving efficiency.
