Description

Technical Field

[0001] The invention relates to the technical field of slope protection, in particular to a flexible reinforced honeycomb cell and a flexible three-dimensional protection net. Background Art

[0002] At present, slope ecological restoration and ecological greening are mainly achieved by soil spraying and a series of improved technologies (including adding various materials to reduce weight and increase viscosity such as fibers, rice husks, adhesives, concrete, etc. into the matrix, or using ecological sticks, wooden boards, geocells and other materials to reduce the slope in a local area before carrying out the soil spraying process).

[0003] However, this type of technology is mainly used on self-stabilizing soil slopes or low rock slopes, and is difficult to implement on high and steep rock slopes. Even if it is barely implemented, the soil layer is either extremely thin and cannot meet the needs of plant growth, or it is easily peeled off under rain erosion, wind erosion and gravity, and cannot be used for a long time.

[0004] Traditional geocells can be laid flat and then filled with soil for slope greening. However, this type of geocell has low strength and insufficient thickness, and is generally only used for slopes below 1:1. At the same time, since these cells are produced in batches, they cannot be laid flat and fixed when encountering uneven natural slopes, and cannot be used on high and steep rock slopes. Other similar technologies are similar in that their adaptability to natural slopes is extremely limited, and generally require standardized slope cutting before use.

[0005] At present, the more common slope protection nets are mainly the following:

[0006] 1. The protective net is made into an overall rigid mesh, which is more suitable for low slopes with high flatness; however, if it is used on uneven slopes, the hollows will not be effectively protected. Even if the slope is cut on a high slope, the soil will easily slide down on the high slope, causing hollows to appear again.

[0007] Second, the individual cells in the protective net are designed to be rigid and fixed by anchor rods. When the soil slides down at a certain place, the force is only concentrated on the cell and cannot be effectively dispersed, which can easily tear and damage the cell.

[0008] 3. Use the anchor rod as the stress point of a single cell. The anchor rod is wound around the winding material to form a cell. This is more ideal than the second stress situation. However, it is still a single cell that is stressed, the force cannot be dispersed, and this installation method is inefficient. Summary of the invention

[0009] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a flexible reinforced honeycomb cell and a flexible three-dimensional protective net that has uniform force dispersion, fast force diffusion speed, long service life, simple structure, easy transportation, easy assembly, can be filled with thicker soil, and plant roots can freely shuttle through.

[0010] The object of the present invention is achieved through the following technical solutions: a flexible reinforced honeycomb cell and a flexible three-dimensional protective net, wherein the flexible reinforced honeycomb cells are connected to form a flexible three-dimensional protective net; the flexible reinforced honeycomb cells include a border frame and a mesh layer arranged therein; the border frame is formed by splicing a plurality of frame units.

[0011] Furthermore, the frame unit is woven from a single steel wire.

[0012] Furthermore, the frame unit is formed by two frame sides at an angle and tightened by steel wire to form a triangle; the frame frame is formed by two frame units spliced ​​into a diamond shape through a connecting ring.

[0013] Preferably, the mesh layer is one or more of a polygonal wire grid, a three-dimensional mesh, a plastic mesh, a geonet, and a Mac gasket, and is used for reinforcing the foreign soil inside the frame.

[0014] Furthermore, the frame unit also includes non-woven fabric, which is sleeved on the edge of the frame and fixed by sewing.

[0015] Furthermore, the steel wire used for weaving the frame unit has a tensile strength of ≥1000Mpa and a weight of ≥160g / m 2 The zinc-aluminum alloy coating is treated for surface corrosion resistance.

[0016] Furthermore, the non-woven fabric is made of polypropylene, with a breaking strength of ≥8KN / m, a breaking elongation of ≤35%, and a unit mass of 200 / m 2 ±5%; its UV resistance retention rate is ≥90% in 500h, and its acid and alkali resistance retention rate is ≥90% in 500h.

[0017] Furthermore, in the flexible three-dimensional protective net, the flexible reinforced honeycomb cells are connected and fixed by quick connection rings; when the flexible three-dimensional protective net is placed on a slope, the steel wire edges that play a tensioning role between the two frame edges are arranged to bear load in the height direction.

[0018] Furthermore, when the flexible three-dimensional protective net is placed on the slope, it is suspended and fixed on the anchor rods through the first row of flexible reinforced honeycomb cells.

[0019] The present invention has the following advantages:

[0020] (1) The frame unit formed by weaving a single steel wire and the frame frame formed by splicing the connecting rings make the entire flexible reinforced honeycomb cell very flexible. When placed on a slope, when the soil has a tendency to slide down, the force can be quickly transmitted to the surrounding flexible reinforced honeycomb cells. The number of flexible reinforced honeycomb cells transmitted is large, the force propagation speed is fast, and the force borne by a single flexible reinforced honeycomb cell is small. Compared with traditional rigid cells, this solution is not prone to cracking and has a longer service life.

[0021] (2) The structure of this solution is very flexible and can fit tightly even on uneven slopes without cutting the slope, making it suitable for slope protection with large slopes.

[0022] (3) The single steel wire weaving method allows the flexible reinforced honeycomb cells to generate an inward force when the soil slides, thereby making the force on the surrounding side uniform and further avoiding tearing;

[0023] (4) The materials used are characterized by high strength, corrosion resistance and light weight, which further ensures the service life;

[0024] (5) The structure of this solution is stable and reliable, light in weight, and easy to transport; and it is easy to assemble only through connecting rings and quick connecting rings;

[0025] (6) Since the entire cell and the flexible three-dimensional protective net have good elasticity, high strength, and rapid force transmission, thicker soil filling can be carried out; and the use of non-woven fabrics and steel wire structures is also conducive to the free movement of plant roots.

[0030] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0031] like Figure 1~Figure 3As shown, a flexible reinforced honeycomb cell and a flexible three-dimensional protective net are connected to form a flexible three-dimensional protective net. The flexible reinforced honeycomb cell includes a frame 1 and a mesh layer 2 arranged therein; the frame 1 is formed by splicing a plurality of frame units 3; and the frame unit 3 is woven from a single steel wire.

[0032] In this solution, the frame unit 3 is two frame edges 301 at an angle, which are tightened by steel wire to form a triangle shape, and a non-woven fabric is also sleeved on the frame edge 301 close to the frame edge, and the non-woven fabric is fixed by sewing. The two frame units 3 are spliced ​​into a frame frame 1 through a connecting ring, and the frame frame 1 is rhombus-shaped.

[0033] Connection ring Figure 3 The invention comprises a long waist-shaped part and a connecting sleeve, wherein the long waist-shaped part has a notch, and the notch is threadedly adapted with the connecting sleeve. When installing, the connecting sleeve is twisted to allow the notch to leak out, the frame unit 3 is inserted into the notch, and then the connecting sleeve is twisted again to close the notch, so that the connection is convenient.

[0034] The flexible reinforced honeycomb cells are connected to the flexible three-dimensional protection net through a quick connection ring. When the flexible three-dimensional protection net is placed on the slope, the steel wire edge for tensioning between the two frame edges 301 is arranged to bear the load along the height direction.

[0035] When part of the soil on the slope tends to slide, it is isolated and trapped by the flexible reinforced honeycomb cells. Due to gravity, the soil exerts a pulling force on the steel wire edge that acts as a tension between the two frame edges 301. Since the frame unit 3 is woven from a single steel wire, it is in a tightened state under the action of tension, so a tightening force is generated in its circumference, which is then dispersed and absorbed by the surrounding frame units 3. Since it is woven from a single steel wire, the tension generated on the circumference is relatively uniform, and there will be no situation where a certain part is torn due to excessive force; and even if the tension on the circumference is relatively large, the single steel wire weaving method will not cause it to fall apart. Therefore, the service life of the flexible three-dimensional protective net is greatly improved.

[0036] In order to further ensure the service life of the flexible three-dimensional protective net, it is required that: the steel wire used for weaving the frame unit 3 has a tensile strength of ≥1000Mpa and a material of ≥160g / m 2 The zinc-aluminum alloy coating is treated for surface corrosion resistance.

[0037] In the force of soil sliding, the steel wire plays the role of tendons, but at the same time the non-woven fabric will also be stressed. Since the non-woven fabric is exposed to the sun or water erosion for a long time, it is required that the non-woven fabric is made of polypropylene, with a breaking strength of ≥8KN / m, a breaking elongation of ≤35%, and a unit mass of 200 / m 2±5%; its UV resistance retention rate is ≥90% in 500h, and its acid and alkali resistance retention rate is ≥90% in 500h.

[0038] In this embodiment, the mesh layer 2 is one or more of a polygonal wire grid, a three-dimensional mesh, a plastic mesh, a geonet, and a Mac gasket, and is used for reinforcing the imported soil inside the frame.

[0039] When the flexible three-dimensional protective net is placed on the slope, it is suspended and fixed on the anchor rods through the first row of flexible reinforced honeycomb cells.

[0040] Since the flexible reinforced honeycomb cell is a frame 1 composed of steel wire and non-woven fabric, the flexibility of the entire cell is very large; in the flexible three-dimensional protective net, when a certain flexible reinforced honeycomb cell is subjected to force, the force will be transmitted over a large range, so the force is dispersed effectively, and the force borne by a single flexible reinforced honeycomb cell is small; compared with traditional rigid cells, the service life of the flexible reinforced honeycomb cells of this scheme is greatly improved.

[0041] The above embodiments only express preferred implementation modes, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
