Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 4, an ecological gabion retaining wall comprises a plurality of gabions 100; gabions 100 are laid flat and stacked, half length of gabion 100 is staggered between adjacent upper and lower gabions 100, and two adjacent gabions 100 are fixedly connected.

Gabion 100 includes frame 2, wire net 3 and filler 1, and frame 2 is the cuboid structure, and wire net 3 cladding frame 2 is in order to form the accommodation space who holds filler 1, and filler 1 fills in accommodation space, and the size of filler 1 is greater than the mesh size of wire net 3.

In this example, the frame 2 is provided with the partition net 4, the partition net 4 is distributed in the longitudinal direction of the frame 2, and the mesh size of the partition net 4 is smaller than the size of the filler 1. When the length of the frame 2 is more than twice the height, the number of the separation nets 4 is 2 and the separation nets are distributed at equal intervals. In this example, the screen 4 and the wire mesh 3 are of the same type of mesh, for example hexagonal, with dimensions of 80 x 100 mm.

In this example, a tie bar is provided in the frame 2, and the tie bar connects two different edges of the frame 2. The space between the lacing wires is 50cm so as to control the deformation of the gabion.

In the embodiment, humus soil is further filled at the top of the gabion 100 at the top of the ecological gabion retaining wall, and the filling thickness of the humus soil is 10-15 cm, so that vegetation can grow conveniently.

In this example, the filler 1 is soft stone blocks, and the size of the soft stone blocks is 1.5-2 times of the mesh size of the steel wire mesh 3. The soft stone blocks should be hard, the compressive strength of the filled stone materials should meet the design requirements, the size matching needs to meet the voidage of the design requirements, and the linear appearance of the gabion is ensured. Wherein, the grain size of more than 80% of the soft stone blocks is 100-180 mm, and the grain size of the filling material is preferably about 2 times of the mesh size.

In this example, the length, width and height of the frame 2 are 300cm, 100cm and 100cm, respectively.

In this example, the steel wire mesh 3 is a galvanized steel wire mesh. The diameter of the steel wire is 2.5mm, and the diameter of the side wire is not less than 3.2 mm. The tensile strength of the steel wire is 350-500 MPa, the elongation at break of the steel wire before weaving is not less than 10%, and the elongation at break of the steel wire after weaving is not less than 8%.
