Further, the first strip-shaped sheet 2 may be connected to the third strip-shaped sheet 4, for example, the mesh 1 is taken as an example, and a connection point, namely, a first connection point 1-1, with the third strip-shaped sheet 4 is formed at the peak of the mesh 1 where the first strip-shaped sheet 2 is located; correspondingly, the second strip 3 may also be connected to the fourth strip 5, for example by mesh 1, wherein the second strip 3 is located in the valleys of the mesh 1 to form the connection points with the fourth strip 5, i.e. the third connection points 1-3. Thus the mesh 1 has four connection points, making the mesh 1 more stable.

In the present utility model, the number of the net holes 1 can be multiple, for example, up to thousands, and the whole geotechnical net has the same structure as the net holes 1 except the net holes at the edges, and the rest structures are the same as the net holes 1 except that the number of the connecting points is correspondingly reduced for the net holes at the edges, and the net holes of the geotechnical net have a certain thickness or high continuous multi-net holes to form a strength structure body; the mesh 1 is internally provided with reinforcing areas which are favorable for filling pores with sand, broken stone, waste residues and the like.

In the present utility model, 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 may be made of high molecular polymers, which may be hard or soft high molecular polymers.

In fig. 2, the structure of the second connection point 1-2 and the fourth connection point 1-4 is shown, specifically, elongated slits 6 are formed in the first strip-shaped sheet 2 and the second strip-shaped sheet 3 at uniform intervals, and the first strip-shaped sheet 2 and the second strip-shaped sheet 3 are divided into a plurality of small strips 7 for connecting the two strip-shaped sheets by the slits 6. The wire 8 passes through these small strips 7 to connect the first strip 1 to the second strip 2, thus forming the second 1-2 and fourth 1-4 connection points.

The wire 8 is preferably connected in a layered jump through the tabs 7, as shown in fig. 2, the wire 8 may be bent in a U-shape with two arms, and during the layered jump through the wire 8 will pass through each tab 7, but for each tab 7 only one of the two arms of the U-shaped wire 8 is located above the tab 7 and the other arm is located below the tab 7.

The tail ends of the U-shaped metal wires 8 can be connected together in a spiral lap joint mode, for example, the tail ends of the U-shaped metal wires 8 can be screwed together through tools such as pliers, so that a spiral lap joint mode is formed, the connection mode is particularly convenient for field construction, the construction of the mesh 1 can be completed only by means of simple tools, and the efficiency is high; meanwhile, the metal wire 8 does not need a complex structure, and can be bent into a required U shape by means of simple tools such as pliers, so that the strip-shaped sheet can be connected with the metal wire by means of easy-to-obtain simple tools, and the metal wire is very convenient, low-cost and efficient for geotechnical nets needing field construction.

The above description about 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 may be formed in the same manner as the second connection point 1-2 or the fourth connection point 1-4, and will not be repeated herein.

Example 2

This embodiment focuses on differences from embodiment 1, and the details of the differences are not repeated. Referring to fig. 3, in this embodiment, the spiral lap joint has a turnover part 10 straight to the outside of the U-shaped wire, and because the geonet needs to be filled with filler such as soil and sand in the grid 1 during construction, in the process of manually filling the filler, the spiral lap joint 9 in embodiment 1 has a relatively sharp point, which is easy to cause damage to human body, and after the turnover part 10 is adopted, the damage of the point can be effectively avoided.

Example 3

In this embodiment, as shown in fig. 4, two wires are provided, namely, a left wire 11 and a right wire 12, which are connected to the first strip-shaped sheet 1 and the second strip-shaped sheet 2 in a layered jump connection manner, and the head ends 9-2 and the tail ends 9-1 of the two wires are respectively spirally overlapped.

Example 4

In this embodiment, with the exception of two wires, referring to FIG. 5, the spirally overlapped leading and trailing ends form turns 10-1 and 10-2.

Example 5

Referring to fig. 6 and 7 together, in this embodiment, the first strip 2, the second strip 3, the third strip 4 and/or the fourth strip 5 are substantially saw-toothed, and the saw-tooth top angle is preferably 90 degrees, so that the mesh 1 has a substantially square shape.
