Description

Ground fixing structure where vegetation is possible {GROUND FIXING STRUCTURER WHICH THE PLANTS CAN BE LIVED IN}

The present invention relates to a ground fixing structure capable of vegetation, and more particularly, to a ground fixing structure capable of vegetation capable of improving erosion prevention effect and environmentally friendly protection and reinforcement of the ground.

In general, slope protection work is being implemented as a measure to reinforce the slope to prevent erosion and greening of river basin dimensions, landscaping, revetment slopes, cut and fill slopes.

In the slope protection construction, a method of reinforcing the entire slope with a concrete structure such as a concrete block was mainly applied, but it is not eco-friendly and has a poor appearance.

In order to compensate for these shortcomings, various methods have been proposed in recent years. For example, Korean Patent Publication No. 10-1598582 discloses a slope protection technology for a'stone net preventing loss' as a technology proposed by the present applicant.

The stone net, which is prevented from being lost according to the above Patent No. 10-1598582, includes a nonwoven fabric 10 disposed on a slope as shown in FIG. 1; A wire mesh 20 disposed on the nonwoven fabric; A buried steel plate 31 buried in the ground on the slope on which the non-woven fabric and wire mesh are installed, an arrangement pin 32 installed in the upper direction of the buried steel plate and protruding to the ground on the slope, and the non-woven fabric installed on the protrusion of the arrangement pin And a fixed anchor 30 made of a fixed steel plate 33 for fixing the wire mesh to the slopes. A plurality of stones 40 disposed on the wire mesh; And a fixing washer 50 disposed under the nonwoven fabric to fix each of the plurality of stones to the nonwoven fabric and the wire mesh.

The aforementioned stone net, which is prevented from loss, has the advantage of replacing the concrete structure and improving the appearance to some extent as natural stone is exposed to the outside, but a plurality of stones 40 must be placed on the wire mesh 20 and fixed. Therefore, the work is difficult and takes a lot of time, so there is a disadvantage that the city park price is increased and the duration is increased.

In addition, the stone net that is prevented from loss of the related art has a limitation in that it is difficult or impossible to vegetation as the stone 40 is arranged on the surface of the wire mesh as a whole, so that an eco-friendly green area cannot be created, and thus the erosion prevention effect is lowered. .

In addition, the stone net that is prevented from loss in the related art requires a separate stone 40, so it is impossible to construct it in an environment where natural stone cannot be easily obtained or under field conditions, and it is necessary to secondarily damage natural objects, such as having to drill a fastening hole in the natural stone. There is a drawback.

And, as described above, the pocket fixing part 4 has a fixed net 1 and a vegetation pocket part in addition to the fixed body 41 that performs a function of pressing the fixed net 1 and the vegetation pocket part 3 downward. 3) A compression wedge portion 42 formed at the edge of the fixed body to perform the function of preventing separation and maintaining the fixed state, and a central fixing protrusion 43 formed in the center of the fixed body 41 is further provided. have. In addition, a plurality of reinforcing protrusions 45 are formed on the upper surface of the fixed body to improve durability and a deformation preventing function to prevent deformation of the fixed body 41.

In this embodiment, the pocket fixing part 4 is fastened to a screw rod located inside the vegetation pocket part so as to press the inner surface of the vegetation pocket part 3.

On the other hand, the ground fixing structure capable of vegetation according to the present invention may be provided with a non-woven fabric (not shown) for stabilizing the slope on which the fixing net 1 is installed.

The non-woven fabric is installed between the bottom surface of the fixed net 1 and the surface of the ground, and may be installed by selecting a thickness suitable for the field conditions among known non-woven fabrics disposed on the ground.

Hereinafter, the construction method and operation of the ground fixing structure capable of vegetation according to an embodiment of the present invention will be briefly described.

In the construction method of the ground fixing structure capable of vegetation according to an embodiment of the present invention, after performing the slope arrangement step of arranging the slopes of the planned site of the construction site, the fixing anchor part installation step, the fixed net arrangement step, the vegetation pocket part arrangement step , Fixed net and pocket fixing steps, vegetation pocket finishing steps, etc. are performed sequentially or non-sequentially for construction.

In the step of installing the fixed anchor unit, the buried anchor member 21 is coupled to the buried anchor fixing member 23, and the buried anchor member 21 is fastened to the lower portion of the screw rod 22, and then an insertion device such as a breaker is used. By performing the press-fitting operation, a plurality of fixed anchor portions 2 are installed at regular intervals. At this time, the screw rod 22 is installed so that the upper part is exposed to the surface of the ground as shown in Fig. 5A.

In the step of arranging the fixed net, the fixed net 1 is disposed on the slope, and the upper portion of the screw bar 22 is exposed. At this time, a nonwoven fabric may be additionally installed on the bottom of the fixed net to prevent erosion of the ground, or a vegetation cloth planted with seeds may be additionally installed.

In the step of arranging the vegetation pocket part, as shown in FIG. 5A, the vegetation pocket part 3 is inserted and installed in the exposed part of the screw rod 22 exposed through the fixing net 1 so that the vegetation pocket part 3 is positioned correctly.

In the step of fixing the fixed net and pocket, the fixed net 1 and the pocket fixing part 4 are pressed by fastening and pressing the pocket fixing part 4 on the exposed part of the screw rod 22 exposed to the inner surface of the vegetation pocket part 3. This is the step of fixing.

More specifically, in the step of fixing the fixing net and the pocket, the shape shown in FIG. 7B is obtained by performing a fastening operation in a state in which the upper screw hole 44 of the pocket fixing part 4 is aligned with the screw rod 22. Implement it whenever possible.

At this time, the fixed body 41 has its bottom surface pressing the fixed net 1 and the vegetation pocket part 3 downward, and the compression wedge part 42 removes the ground from the edge of the fixed body 41. As it is inserted toward the fixed net (1) and the vegetation pocket (3) to prevent separation and to perform the function of maintaining the fixed state. In addition, since the reinforcing protrusion 45 can prevent deformation by reinforcing the upper surface of the fixed body 41, it is possible to stably maintain a fixed state for a long time and improve durability.

The vegetation pocket finishing step is a step of finishing the vegetation pocket part 3 in a state in which vegetation is possible, and when the fixing net and pocket fixing steps are completed as described above, the state before suture is opened in the form shown in FIG. 5A.
