Description

Technical Field

[0001] This invention belongs to the technical field of water conservancy slope protection, and in particular relates to a PET gabion mesh box with an anti-erosion reinforcement layer and its preparation method. Background Technology

[0002] Gabion cages are flexible structures widely used in water conservancy projects such as riverbank protection, bank protection, and soil and water conservation. They are made of wire mesh and filled with boulders or pebbles, utilizing the weight of the stones and the overall integrity of the cage to resist water erosion and prevent bank collapse. Compared to traditional concrete revetments, gabion cages offer advantages such as convenient construction, low cost, and eco-friendliness (plants can grow between the stones), making them widely used in the management of small and medium-sized rivers and ecological bank protection projects.

[0003] However, traditional gabion cages have revealed numerous problems in terms of durability and erosion resistance in practical applications. First, traditional cages are mostly woven from galvanized low-carbon steel wire. When immersed in river water for extended periods, especially in water with abnormal pH levels or industrial pollution, the galvanized layer is easily corroded and damaged, leading to rusting and breakage of the steel wire and a significant decrease in the strength of the cage. Second, the structure of traditional gabion cages is mainly flexible wire mesh, lacking internal rigid frame support. When rivers encounter high-velocity floods during the flood season, the water flow generates tremendous impact and turbulence on the upstream surface, causing a sharp increase in local stress on the wire mesh of the gabion cage. This makes it prone to cracking at the mesh edges or weaving joints. Once the wire mesh is damaged, the internal stones will be lost, and the gabion cage will collapse rapidly. Thirdly, the upstream surface of traditional gabion cages is often a flat or simple wire mesh surface without a dedicated flow guiding and buffering structure. High-speed water flow directly impacts the mesh surface, generating a strong "water hammer" effect and pulsating pressure. This not only exacerbates the vibration of the gabion cage but also erodes the foundation soil from the bottom, causing the bottom of the cage to become suspended, ultimately leading to the slippage or collapse of the entire slope protection structure. Therefore, we provide a PET gabion cage with an erosion-resistant reinforcing layer and its preparation method to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a PET gabion mesh box with an anti-erosion reinforcement layer and its preparation method. By using the reinforcing ribs, the gabion mesh box can remain stable under high flow velocity and strong turbulence conditions during the flood season in the river, which significantly extends the service life of the slope protection project. At the same time, the pins, cross bars and connecting bars prevent the wire mesh from cracking or breaking due to excessive local stress, which greatly improves the overall tensile and shear strength of the gabion.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a PET gabion box with an anti-erosion reinforcement layer, comprising a wire mesh frame composed of four sets of wire mesh, a bottom wire mesh frame at the bottom of the wire mesh frame, and a wire mesh box cover located above the wire mesh frame; two sets of reinforcing ribs arranged left and right on the inner side of the water-facing side of the wire mesh frame, multiple permeable holes arranged in an array on the side of the reinforcing ribs, multiple guide grooves evenly distributed left and right on the water-facing side of the reinforcing ribs, an arched buffer layer plate installed on the back side of the reinforcing ribs, and a reinforcement layer plate composited at the lower end of the bottom wire mesh frame.

[0007] The invention is further configured such that pin ribs are provided at the diagonal positions on all four sides of the wire mesh frame, transverse ribs are provided at the major diameter positions at the top and bottom of the wire mesh frame, and connecting ribs are provided at the minor diameter positions at the top and bottom of the wire mesh frame.

[0008] The invention is further configured such that each group of wire mesh edges of the wire mesh frame is connected to the corresponding pin reinforcement, cross reinforcement and connecting reinforcement by straps.

[0009] The present invention is further configured such that nodes are provided at the connection points of the pin reinforcement, the cross reinforcement and the connecting reinforcement, and the side of each node is welded to the corresponding pin reinforcement, the cross reinforcement and the connecting reinforcement.

[0010] The invention is further configured such that a wire mesh is provided inside the wire mesh frame, wherein the wire mesh, except for the upper end, is connected to the bottom wire mesh frame and the wire mesh frame by cable ties.

[0011] The invention is further configured such that the wire mesh box cover is connected to the upper end of the wire mesh via a hanging buckle, and the four sides of the wire mesh box cover are hung on the corresponding connecting ribs and transverse ribs via double-headed hooks.

[0012] The invention is further configured such that ring blocks are installed on the upper parts of both the left and right sides of the reinforcing rib, and each ring block is connected to the wire mesh frame by a cable tie.

[0013] The invention is further configured such that a dovetail groove is provided on the lower end face of each reinforcing rib, and a dovetail pin is slidably disposed inside the dovetail groove. The dovetail pin is connected to the bottom wire mesh frame through a reinforcing buckle on the side wall.

[0014] This invention also provides a method for preparing a PET gabion mesh box with an erosion-resistant reinforcement layer, which is prepared through the following steps:

[0015] S1: The wire mesh frame, bottom wire mesh frame, wire mesh box cover and reinforcing ribs are all injection molded from high-strength PET composite material. The wire mesh frame is connected by cable ties, pins, cross bars and connecting bars.

[0016] S2: During on-site installation, the reinforcing ribs are first placed on the water-facing side of the wire mesh frame. The rings at the edge of the reinforcing ribs are installed on the wire mesh frame with cable ties. At the same time, the dovetail pins are inserted into the dovetail grooves, and the reinforcing buckles are fastened to the bottom wire mesh frame. Therefore, the bottom wire mesh frame pulls on the dovetail pins to limit the position of the reinforcing ribs.

[0017] S3: Then install the bottom wire mesh frame at the bottom of the wire mesh frame, and fill the inside of the wire mesh frame on the left side of the wire mesh with stones, with the lower layer filled with coarse aggregate and the upper layer filled with medium and fine aggregate;

[0018] S4: After filling, cover the top of the wire mesh box with the cover to achieve a seal.

[0019] The present invention has the following beneficial effects:

[0020] 1. This invention features two sets of reinforcing ribs on the inner side of the wire mesh frame facing the water. The ribs have flow channels on their facing side to manage turbulent water flow and reduce impact. An arched buffer layer is installed on the back side to absorb water hammer energy. Permeable holes are also provided to balance the water pressure inside and outside the cage, preventing pressure differences from causing the gabion to float or become hollow. A composite reinforcing layer is added at the bottom of the wire mesh frame to effectively block the direct scouring of the base soil by the water flow, preventing the bottom of the cage from collapsing. This multi-layered anti-scouring structure keeps the gabion stable under high flow velocity and strong turbulence conditions during the flood season, significantly extending the service life of the slope protection project.

[0021] 2. This invention sets pin ribs at the four corners of the wire mesh frame, and sets transverse ribs and connecting ribs in the long and short diameter directions at the top and bottom ends, respectively. The intersection nodes of each rib are welded to form a three-dimensional rigid skeleton. The PET wire mesh is tightly tied to the outside of the ribs with straps. When the weight of the stone and the impact force of the water flow act on the gabion, the multi-directional ribs jointly disperse the load, effectively restrain the deformation of the wire mesh, and prevent the wire mesh from cracking or breaking due to excessive local stress, which greatly improves the overall tensile and shear resistance of the gabion.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 5 This invention relates to a PET gabion box with an anti-erosion reinforcement layer, comprising a wire mesh frame 1 composed of four sets of wire mesh, a bottom wire mesh frame 3 at the bottom of the wire mesh frame 1, and a wire mesh box cover 2 located above the wire mesh frame 1; two sets of reinforcing ribs 4 arranged left and right on the inner side of the water-facing side of the wire mesh frame 1, multiple permeable holes 401 arranged in an array on the side of the reinforcing ribs 4, multiple guide grooves 404 evenly distributed left and right on the water-facing side of the reinforcing ribs 4, an arched buffer layer 402 installed on the back side of the reinforcing ribs 4, and a reinforcing layer 301 composite at the lower end of the bottom wire mesh frame 3.

[0033] Ring blocks 403 are installed on the upper part of both the left and right sides of the reinforcing rib plate 4, and each ring block 403 is connected to the wire mesh frame 1 by a cable tie.

[0034] The pin rib 8, the transverse rib 6, and the connecting rib 5 are welded at node 7 to form a three-dimensional rigid frame, which constrains the deformation of the PET wire mesh. The impact of water flow and the self-weight load of the stone are distributed by the rib frame as a whole to prevent the wire mesh from tearing and breaking.

[0035] Meanwhile, the guide channel 404 of the water-facing reinforced rib plate 4 sorts out the turbulent incoming flow and splits the impact force of the water flow. The arched buffer layer absorbs the kinetic energy of the water hammer. The densely distributed permeable holes 401 balance the water pressure inside and outside the cage and avoid the pressure difference causing the gabion to float or be hollowed out. In addition, the reinforced layer plate 301 of the bottom frame composite blocks the water flow from washing away the base soil and prevents the bottom of the cage from being suspended and collapsing.

[0036] Among them, the upper and lower reinforcing ribs are respectively bound by ring blocks 403 and limited by dovetail buckles, and the wire mesh box cover is locked by two multi-point hooks. The fully prefabricated PET components are quickly assembled on site, resistant to water and soil corrosion, and suitable for various river and slope protection conditions.

[0037] Example 1, according to Figure 1 It can be seen that the wire mesh frame 1 is provided with pins 8 at the four diagonal positions, the wire mesh frame 1 is provided with transverse reinforcing bars 6 at the long axis positions at the top and bottom ends, and the wire mesh frame 1 is provided with connecting bars 5 at the short axis positions at the top and bottom ends. Each set of wire mesh edges of the wire mesh frame 1 is connected to the corresponding pins 8, transverse reinforcing bars 6 and connecting bars 5 by binding straps. Nodes 7 are provided at the connection points between the pins 8, transverse reinforcing bars 6 and connecting bars 5. Each node 7 is welded to the corresponding pins 8, transverse reinforcing bars 6 and connecting bars 5 on its side.

[0038] In this embodiment, the various reinforcing material intersection nodes 7 are fixed by welding. The PET wire mesh is tightly tied to the outside of the reinforcing material with straps to form a cage. Relying on the mutual restraint of the multi-directional reinforcing materials, the overall tensile strength of the wire mesh is greatly improved. Under the high water flow impact conditions during the flood season of the river, the wire mesh is prevented from cracking and deforming due to the squeezing of stones and the tearing of water flow. At the same time, the PET material is resistant to acid and alkali corrosion and is not easy to rust or breakage in the long-term use in the immersion environment of river and lake water and soil. On-site assembly only requires binding, without the need for on-site welding of wire mesh, which greatly shortens the assembly period of the gabion and is suitable for batch construction of river slope protection.

[0039] Example 2, based on Example 1, according to Figure 2 and Figure 3 It can be seen that the wire mesh frame 1 is provided with a wire mesh 9 inside. Except for the upper end, the other sides of the wire mesh 9 are connected to the bottom wire mesh frame 3 and the wire mesh frame 1 by cable ties. The wire mesh box cover 2 is connected to the upper end of the wire mesh 9 by the hanging buckle 201. The four sides of the wire mesh box cover 2 are hung on the corresponding connecting ribs 5 and transverse ribs 6 by double-headed hooks 202.

[0040] In this embodiment, the upper end of the wire mesh box cover 2 is connected to the top of the wire mesh 9 via a hanging buckle 201. The surrounding area is hooked to the transverse reinforcing bar 6 and the connecting reinforcing bar 5 using double-headed hooks 202. After the filling is completed, the wire mesh box cover 2 is closed. At the same time, the double-headed hooks 202 are used to lock the cage opening at multiple points to prevent the stones from leaking out from the top after the water rises. The wire mesh 9 divides the internal space of the wire mesh 9 frame 1, improves the water permeability and reverse filtration performance of the gabion, reduces the loss of fine materials, and optimizes the slope protection, seepage prevention, and anti-hollowing effect. For later maintenance, the double-headed hooks 202 can be directly removed to open the wire mesh box cover 2, making disassembly and assembly convenient.

[0041] Example 3, based on Example 2, according to Figure 4 and Figure 5 It can be seen that the lower end face of the reinforcing rib 4 is provided with a dovetail groove 405, and a dovetail pin 406 is slidably provided inside the dovetail groove 405. The dovetail pin 406 is connected to the bottom wire mesh frame 3 through the reinforcing buckle 407 on the side wall.

[0042] In this embodiment, the dovetail groove 405 and the dovetail pin 406 slide together, and the dovetail pin 406 is secured to the bottom wire mesh frame 3 by means of the reinforcing buckle 407, forming a bidirectional limit by the tension of the bottom wire mesh frame 3.

[0043] Example 4: The present invention also provides a method for preparing a PET gabion mesh box with an erosion-resistant reinforcement layer, which is prepared by the following steps:

[0044] S1: The wire mesh frame 1, the bottom wire mesh frame 3, the wire mesh box cover 2 and the reinforcing rib 4 are all injection molded from high-strength PET composite material. The wire mesh frame 1 is connected by cable ties, pins 8, cross ribs 6 and connecting ribs 5.

[0045] S2: During on-site installation, the reinforcing rib 4 is first placed on the water-facing side of the wire mesh frame 1. The ring block 403 at the edge of the reinforcing rib 4 is installed on the wire mesh frame 1 by cable ties. At the same time, the dovetail pin 406 is inserted into the dovetail groove 405, and the reinforcing buckle 407 is fastened to the bottom wire mesh frame 3. Therefore, the bottom wire mesh frame 3 pulls on the dovetail pin 406 to limit the position of the reinforcing rib 4.

[0046] S3: Then install the bottom wire mesh frame 3 at the bottom of the wire mesh frame 1, and fill the inside of the wire mesh frame 1 to the left of the wire mesh 9 with stone, with the lower layer filled with coarse aggregate and the upper layer filled with medium and fine aggregate.

[0047] S4: After filling, cover the top of the wire mesh box 2 with the wire mesh frame 1 to achieve a seal.
