Description

Construction method for vegetation gabion recruitment using multi-functional integrated plastic box}

The present invention relates to a method of constructing a gebion structure for vegetation survival using a multifunctional plastic box.

Conventionally, structures such as concrete retaining walls, gabion retaining walls, block retaining walls, stone shafts, concrete blocks, and gabions have been mainly used for the purpose of slope stability and dimensional stability during maintenance of road cut soil slopes or river banks. However, there is no space for vegetation in these structures. Accordingly, there is a problem in that the ecosystem is destroyed in the case of using such structures in the related art to maintain a cut road or river embankment.

Regarding the construction method of the Gebion retaining wall, in Patent No. 10-1898458, the applicant has a longer length than the vegetation bag and the vegetation bag for filling the top soil, and simultaneously accepts the back filling bag and the vegetation bag and the back filling bag to support the vegetation bag from the back. Prepare a composite bag structure consisting of a non-watertight bulkhead partition that spatially separates the bag and the backfill, install the foundation retaining wall after digging at the site, install the complex bag structure on the foundation retaining wall, and install the vegetation bag on the foundation retaining wall. A construction method consisting of the process of constructing a composite bag retaining wall by filling the top soil and filling the backfill bag with mixed stone or useful soil was proposed.

In the process of the above patent, a vegetation bag made of polypropylene is fabricated by cutting, sewing, and perforating the connector, and the backfill bag is also manufactured through fabric cutting and sewing, and then Gebion wire mesh (wire mesh) is formed into a hexahedron After assembling, the vegetation bag is folded and installed in the front of the wire mesh so that the upper part becomes an open hexahedron, and similarly to the rear side of the wire mesh, it relies on the process of attaching the rear fill bag. However, in the Gebion retaining wall structure assembled in this way, the material of the bag that directly accommodates the soil is relatively weak, and only the wire mesh protects the bag from the outside. Therefore, scaffolding is essential to maintain the shape of the composite bag structure. Scaffolds are separated before construction is completed, but installation and disassembly of scaffolds is an obstacle to improving workability and reducing construction costs. In addition, when the vegetation bag and the backfill bag are first manufactured, they are manufactured to have a shape that is spread out in a hexahedron at the site, so there is a problem that a lot of labor is required and the bag manufacturing process is cumbersome.

The inventor of the present application further improved the Gebion retaining wall structure to invent a method for constructing a Gebion structure for vegetation survival using a multifunctional plastic box that is easy to install, inexpensive, eco-friendly, and has an excellent drainage structure.

It consists of a process, and the above construction method additionally fills the inside of the vegetation bag and performs compaction, then installs a nonwoven fabric on the open upper part of the Gebion structure, covers the upper part with a separate wire mesh lid, and refills the excavation space. By performing the compaction work at the same time, it may further include a process of completing the construction of the Gebion structure for vegetation survival.

Of the drain board panels, at least the first side board panel and the second side board panel installed to face the first side board panel have internal drainage grooves formed on the inner surface, and embossed protrusions protrude on the outer surface thereof, and through the projections. May have a structure in which an external drainage groove communicating with the internal drainage groove is formed.

1 is a flow chart illustrating a method of constructing a gebion structure for vegetation survival using a multifunctional plastic box according to an embodiment of the present invention. In the necessary steps, real photos were added for convenience of understanding.

First, to produce a vegetation bag (10) (S10). The vegetation bag 10 is made of polypropylene or polyethylene-based nonwoven fabric. At this time, the vegetation bag (10) is manufactured in a flat surface as shown in the photo, and is manufactured in a roll type that can be rolled up. Therefore, the manufacturing process of the vegetation bag 10 is easier and faster than the existing one. In the present invention, the back filling bag as in the existing structure is not used. In parallel with the step (S10), the assembled drain board panel 20 is manufactured (S12). Each drain board panel 20 is made of a rectangular plate, and as will be described later, six rectangular drain board panels (front, bottom, both sides, rear and partition panels) are assembled to open the top and open the middle. A hexahedral plastic box with partitions is completed.

It is preferable that the plastic box is made of a drain board having excellent drainage properties. An example of such a drain board is shown in FIG. 5.

In parallel with these steps (S10, S12), a substantially rectangular floor frame 30 made of a rigid material that provides a basic frame for assembling a plastic box is manufactured (S14).

In addition, in parallel with these steps (S10, S12, S14), a wire mesh 40 for receiving and protecting the plastic box from the outside is manufactured. The wire mesh 40 is manufactured and supplied as a plurality of plates to form a set of five wire mesh panels for completing a hexahedron with an empty upper part at the site. The outside of the wire mesh 40 is preferably galvanized.

The roll-shaped vegetation bag 10, a plurality of plate-shaped drain board panels 20, and the floor frame 30 and the wire mesh 40 are carried into the site (S20). These members are made of roll-type or stacked square plates and are transported and carried, so they are convenient for mass production and movement.

By combining these members, the Gebion structure 1 is assembled (S30). The detailed assembly process of the Gebion structure 1 will be described later.

after. Filling the inside of the vegetation bag 10 and performing a compaction operation (S40). Install the nonwoven fabric on the open upper part of the Gebion structure (1), cover the upper part with a separate wire mesh lid (S50), and perform compaction work at the same time as the backfilling space (S60) to construct the Gebion structure for vegetation survival. Complete.

In the present invention, since a relatively sturdy plastic box is used, there is no fear of changing or distorting the shape of the structure during the filling process, so there is no need to install a scaffold, so the construction process is shortened, and it is advantageous quickly and economically.

2 is a perspective view before assembly to show each member constituting the Gebion structure 1 of the present invention. The wire mesh 40 is assembled in a hexahedron with an open top at the site, and its description will be omitted here.

The bottom frame 30 has a shape of a long rectangular frame, and a crossbar 304 is installed in front of the frame. Long grooves 302 are formed at each side along the frame. A convex coupling portion 306a protruding convexly is formed on the right side, and a concave coupling portion 306b having a shape for closely accommodating the convex coupling portion 306a is formed on the left side (see Fig. 3).

The drain board panel 20 includes a front board panel 20a, a first side board panel 20b, a second side board panel 20c facing the first side, a rear board panel 20d, and a partition board panel 20e. ) And a floor board panel (20f).

Since the structure and shape of the other panels except for the front board panel 20a are the same, the structure of the panel will be described based on the first side board panel 20b. Internal drainage grooves 200 for drainage are formed at dense intervals on the inner surface of the first side board panel 20b, and conical protrusions 202 protruding outward are formed at dense intervals such as embossing on the outer surface. Through the entire length of the protrusion 202, the external drain groove 204 is perforated so as to communicate with the internal drain groove 200. Water inside the plastic box is discharged to the outside through these drainage grooves.

In the case of the front board panel 20a, the outer surface is flat, but a honeycomb (honeycomb) reinforcement bar 210 is formed on the inner surface to increase strength. (200') is the front board drainage groove.

At the site, the front board panel 20a, the first side board panel 20b, the second side board panel 20c, the rear board panel 20d, the partition board panel 20e, and the floor board panel 20f are The plastic box is completed by being fitted into the corresponding groove 302 of the frame 30.

3 is a view showing in detail the step (S30) of assembling the Gebion structure (1) of the present invention.

First, after preparing a plurality of floor frames 30, the convex coupling portion 306a and the concave coupling portion 306b are fitted to form, for example, three floor frames 30.

Next, the floor board panel 20f is fitted to the bottom of each floor frame 30 and assembled.

Next, based on each floor frame 30, a front board panel 20a, a first side board panel 20b, a second side board panel 20c, a rear board panel 20d, and a partition board panel 20e are formed. Fit and assemble to complete the plastic box.

Next, assemble so that the area except the upper part of the plastic box is surrounded by wire mesh panels and stacked. At this time, the front part of the plastic box is assembled and kept open without closing.

Next, by pushing the vegetation bag 10 supplied in a roll type through the open front part, the upper part is opened between the front board panel 20a, the partition board panel 20e, and the floor board panel 20f of the plastic box. Build a turret and close the wire mesh panels on the front. In the vegetation bag 10, a transverse net and a net made of polyethylene or polypropylene may be additionally installed.

The above process completes the Gebion structure 1 having three plastic boxes, and proceeds to the process (S40) of filling and compacting the vegetation bag (10). Even if the top soil is filled in the vegetation bag 10, since the rigidity of the front board panel 20a is reinforced with a honeycomb structure, there is no need to install a scaffold as in the prior art.

Of course, the number of plastic boxes does not limit the scope of the present invention.

4 is a schematic configuration diagram for explaining the drainage function of the Gebion structure 1 consisting of three plastic boxes. Arrows indicate the direction of water drainage.

In the case of the adjacent plastic box, as shown in the enlarged view, a drainage passage may be naturally formed between the protrusions 202 of the first side board panel 20b and the second side board panel 20c. For this purpose, it is preferable to make a curved drainage passage by arranging the left and right protrusions 202 at an angle to each other. The water introduced from the rear surface as shown in FIG. 4 may be discharged along the side through the drainage channel between adjacent plastic boxes by such a drainage channel. Of course, water is also drained through the inner voids and grooves 200 and 204 of the plastic box, but the plastic box structure of the present invention has an advantage in that it provides a drainage passage through which water quickly exits in a predetermined direction without obstructions.

According to the present invention, since water is three-dimensionally drained through the embossing structure on both sides of the plastic box, natural irrigation is made to the entire vegetation, contributing to vegetation survival, and applying useful soil on site, thereby reducing costs such as purchasing crushed stone aggregates and reducing residual soil treatment costs. It can be reduced and the safety of the structure can be guaranteed.

In addition to the retaining wall of the steep slope, the construction method and the Gebion structure of the present invention described above can also be applied as a repair and reinforcement method in case of a risk of collapse to a gentle slope of 1:1. When installing a gentle slope, a non-woven fabric can be laid on the back of the plastic box and the non-woven fabric can be fixed with an anchor.

The above-described embodiments and drawings are for illustration of the present invention and do not limit the scope of the present invention. It is obvious that the present invention can be variously changed or modified within the scope of the claims to be described below, and the scope of the present invention extends to the same or equivalent scope as the claims to be described below.
