Example 1

As shown in Figure 1, the new geonet is used for surface protection of slopes, for example. It has multiple meshes 1. The mesh 1 is composed of a first strip-shaped sheet 2 and a second strip-shaped sheet 3. In the figure In 1, the first strip-shaped sheet 2 and the second strip-shaped sheet 3 are wavy, and the mesh 1 can be formed by buckling the crest of the first strip-shaped sheet 2 and the trough of the second strip-shaped sheet 3 together. , the mesh 1 formed by such fastening is roughly elliptical, and the first strip-shaped sheet 2 and the second strip-shaped sheet 3 have two connection points, namely the second connection points 1-2 shown in Figure 1 with fourth connection points 1-4.

Furthermore, the first strip-shaped sheet 2 can also be connected to the third strip-shaped sheet 4. Taking the mesh 1 as an example, the first strip-shaped sheet 2 is located at the peak of the mesh 1 to form a connection with the third strip-shaped sheet 4. The connection point of the sheet 4 is the first connection point 1-1; correspondingly, the second strip-shaped sheet 3 can also be connected to the fourth strip-shaped sheet 5. Taking mesh 1 as an example, in the second strip-shaped sheet The sheet 3 is located at the trough of the mesh 1 to form a connection point with the fourth strip-shaped sheet 5, that is, the third connection point 1-3. In this way, mesh 1 has four connection points, making mesh 1 more stable.

In the present invention, mesh 1 can have multiple meshes, for example, up to thousands. Except for the edge meshes of the entire geonet, these meshes have the same structure as mesh 1. For edge meshes, except for the number of connection points, In addition to the corresponding reduction in mesh size, the rest of the structure is the same as Mesh 1. These meshes of the geonet have a certain thickness or height, and a continuous multi-mesh combination forms a strong structure; the formation in Mesh 1 is conducive to sand, gravel, waste residue, etc. Filling the pores creates reinforced areas.

In the present invention, the first strip-shaped sheet 2, the second strip-shaped sheet 3, the third strip-shaped sheet 4 and/or the fourth strip-shaped sheet 5 can be made of polymers. These polymers are polymerized. Materials can be hard or soft polymers.

Figure 2 shows the structure of the second connection point 1-2 and the fourth connection point 1-4. Specifically, uniformly spaced holes are formed on the first strip-shaped sheet 2 and the second strip-shaped sheet 3. The distributed elongated slots 6 divide the first strip-shaped sheet 2 and the second strip-shaped sheet 3 into a plurality of small strips 7 for connecting the two strip-shaped sheets. The metal wire 8 passes through these small strips 7 to connect the first strip-shaped sheet 1 and the second strip-shaped sheet 2, thereby forming the second connection point 1-2 and the fourth connection point 1-4.

When the metal wire 8 passes through the small strip 7, it is preferable to use a layered jump connection method. As shown in Figure 2, the metal wire 8 can be bent into a U shape, with two arms, and is interspersed in layered jumps. , the metal wire 8 will pass through each small strip 7, but for each small strip 7, only one of the two arms of the U-shaped metal wire 8 is located above the small strip 7, while the other The arms are located under the strip 7.

The ends of the U-shaped metal wires 8 can be connected together in a spiral overlapping manner. For example, the ends of the U-shaped metal wires 8 can be screwed together using pliers and other tools to form a spiral overlapping manner. This connection method It is especially convenient for construction in the field. The construction of the mesh 1 can be completed with the help of simple tools, and the efficiency is high. At the same time, for the metal wire 8, it does not require a complicated structure, and can also only use pliers, etc. It can be bent into the required U-shape with simple tools, and the strip-shaped sheets can be connected using easily available simple tools and metal wires. This is very convenient for geonets that require field construction. , low cost and efficient.

The above is the description of the second connection point 1-2 and the fourth connection point 1-4. The first connection point 1-1 and the third connection point 1-3 can be connected to the second connection point 1-2 or the fourth connection point. Points 1-4 are formed in the same way and will not be described again.

The reinforced protective net provided by this new model is woven into a mesh with a certain thickness or height using strips or sheets formed from polymers. The mesh is a continuous plurality of meshes, and the continuous combination of multiple meshes forms a strong structure. The body has space for filling small-sized fillers such as sand, gravel, waste residue, etc., which is used for plant planting, so that an integral combination is formed between the structure and the filled sand, gravel, soil, etc., and a structural layer is formed on the slope surface. Reinforce the slope to protect the slope surface and play the role of ecological slope protection.

Example 2

This embodiment focuses on the differences from Embodiment 1, and the similarities will not be described again. Referring to Figure 3, in this embodiment, the spiral lap joint has a straight folding portion 10 toward the outside of the U-shaped metal wire. Since the geonet needs to be filled with fillers such as soil, sand and gravel into the grid 1 during construction, manual filling is required. During the filling process, the spiral lap joint 9 in Embodiment 1 has a relatively sharp tip, which can easily cause damage to the human body. By using the folded portion 10, tip damage can be effectively avoided.

Example 3

As shown in Figure 4, in this embodiment, there are two connecting metal wires, namely a left metal wire 11 and a right metal wire 12. The two metal wires are connected to the first strip-shaped sheet in a layered skip connection manner. 1 and the second strip-shaped sheet 2, the head ends 9-2 and the tail ends 9-1 of the two metal wires are spirally overlapped respectively.

Example 4

In this embodiment, in addition to using two metal wires, referring to Figure 5, the head end and the tail end of the spiral overlap form folding portions 10-1 and 10-2.

Example 5

Referring to Figures 6 and 7 together, in this embodiment, the first strip-shaped sheet 2, the second strip-shaped sheet 3, the third strip-shaped sheet 4 and/or the fourth strip-shaped sheet 5 are generally in a zigzag shape. shape, and its sawtooth vertex angle is preferably 90 degrees, so that the mesh 1 can have a roughly square shape.
