The present invention relates to an eco-friendly vegetation mesh retaining wall having a support neck and a method of constructing the same. More particularly, the present invention relates to an eco-friendly vegetation mesh retaining wall having a support neck,

And a mesh net is disposed under the mesh net, and the upper and lower surfaces of the mesh mesh net are arranged so that the upper and lower surfaces of the mesh net, The present invention provides an eco-friendly vegetation mesh retaining wall having an environmentally friendly support neck that not only uses concrete but also improves the safety of the retaining wall structure and reduces air and construction cost, and a construction method thereof .

Generally, the retaining wall is a structure for preventing the soil from falling by resisting the earth pressure. In order to maintain the altitude difference, a block for suppressing the soil is installed on one side of the sloped ground. Concrete, stone, and brick.

Since more than 70% of the country is made up of mountainous areas, cutting slopes are inevitable due to the construction of civil engineering structures such as roads, railway construction, industrial complexes, and housing estates. Moreover, as the slope increases, the slope of the cut slope becomes steep, and concrete concrete stepped retaining wall and PC (Precast Concrete) retaining wall are applied relatively recently. However, such a method has a problem in that it is not compatible with the surrounding area and is a non-environmental construction method.

In order to solve these problems, many retaining walls using vegetation boxes have been developed. However, when the retaining wall is constructed by using the vegetation box, the water supply to the vegetation is not easy, so that when the rain does not fall for a long time, In order to prevent such a problem, it is necessary to spray water artificially, so that maintenance and maintenance costs are increased and maintenance is troublesome.

On the other hand, the retaining wall must be able to withstand the superstructure and the earth pressure sufficiently, have durability, easy to secure the material, and easy to construct. Generally, the shaft is generally equipped with these requirements, There is a disadvantage in that the ability to resist water pressure drops.

In addition, the concrete retaining wall is one of the most commonly used structures. However, there is a shortage of specialized manpower in the construction market, resulting in a rise in labor costs, difficulty in quality control of the on-site concrete, And the increase of the construction cost.

In order to overcome these problems, various types of new retaining wall construction methods have been developed and put into practical use. Among them, the most typical construction method is a retaining wall block construction method using blocks.

In Korean Patent No. 10-0891299, the joining structure of the wall panels is simplified as much as possible, thereby facilitating the longitudinal and transverse joints between the respective layers, improving the stability of the structure, and simplifying the fastening structure between the wall panel and the bottom stiffener. A mesh panel assembled retaining wall structure and a construction method thereof are proposed which improve work efficiency such as material transportation and construction time during construction.

1 is a perspective view showing a structure of a mesh panel assembled retaining wall structure according to a conventional technique.

However, according to the above-described prior art, the mesh panel-assembled retaining wall structure is constructed by connecting a plurality of transverse wires and longitudinal wires in a lattice form, the upper side of which is made up of at least And a lower portion thereof is bent in an L-shape so as to form a horizontal portion, wherein the horizontal bending point is formed by a first transverse wire and a first transverse wire from the first transverse wire, A wall panel having a second transverse wire at intervals of 1 to 1.1 times the diameter of the longitudinal wire; And a bottom reinforcement disposed on the curved horizontal portion of the wall panel to form a unit structure. The unit structure is repeatedly laminated by at least two or more layers so that the projected longitudinal wire of the bottom panel is overlapped with the top wall panel Through the spaced-apart clearance between the first transverse wire and the second transverse wire, and is prevented from tilting.

However, the above-mentioned conventional techniques have a problem in that the construction is complicated and the construction period is increased due to the complexity of the components, and the supporting force of the retaining wall structure is not secured sufficiently, and the disadvantage that the environment- .

In step S80, the above step S30 to step S70 are repeated until the design height, and a retaining wall formed of a plurality of mesh wire meshes 20 is installed, and the work is finished by covering with embankment or road.

That is, as described above, in the construction method according to the preferred embodiment of the present invention, after the foundation concrete is laid and the rubble is laid, the support neck provided with the square washer is installed at a predetermined position. Such that the support neck is smaller than the grid size of the mesh wire mesh but the square washers are formed larger than the grid size of the mesh wire mesh. Next, let the first mesh wire net (bottom end) penetrate through the pre-installed support tree, install the vegetation mat and grid net inside, and finish the compact soil. At this time, it is preferable that the compacted soil is filled with soil in half and filled with the remaining cuts after finishing the filling, but it is preferable to make the compacted to two stages. However, it does not limit the number of compaction within the range that can achieve the same purpose and function.

Next, a support neck provided with a square washer at a lower portion thereof is installed at a predetermined position of the upper end for installation of the upper end, and an upper end mesh wire net is installed through the upper end support neck, The upper part of the support neck is bound to the lower part of the upper end mesh wire net using the supporting iron plate and the washer member. At this time, it is preferable that the upper end support neck which is additionally provided is retreated from the lower end support neck at a predetermined interval.
