Description

Plant iron bar block bag and environment-friendly plant retaining wall using iron bar block

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food bag used for constructing a retaining wall, and more particularly, to an ecological vegetation retaining wall using a vegetation reinforcing block bag and a reinforcing bar block constructed using a reinforcing steel block and a natural mesh.

Reinforced soil retaining wall is a structural method by friction between soil and reinforcement, compared with the commonly used self-rigidity and self-weighted concrete retaining wall, and maintains the function of wall surface and reinforcement against some uneven settlement in foundation ground without any damage. As it is constructed repeatedly by stacking, reinforcing reinforcement, compacting, and assembling the wall surface, it has the advantage of being easy to install on small scale equipment and not significantly affected by the site environment or natural conditions.

The strength-enhancing theory of reinforcement soils sees the effect of the reduced horizontal stress of reinforcement soils as the increase of internal friction angles. The theory of apparent cohesion, which interprets the effect of reduced horizontal stress as the generation of new cohesion, that is, the increase in the confining stress in which the soil in the reinforcement soil is completely constrained by friction with the reinforcement and the soil in the ground is prevented from expanding by the surrounding soil. There is a theory. Therefore, the stability analysis of reinforcement soil retaining wall is examined by the external stability of gravity retaining wall movement, conduction and settlement including reinforcement soil. Evaluate and evaluate internal stability.

Recently, the development of Sustainability System is required, and the front wall of the retaining wall, which is reinforced with natural earth-friendly structure, is applied to the mesh wall or concrete wall, block, geotextile, and grid wall. It has been developed in a vegetative way. However, these attempts are not successful due to high development costs, complicated construction methods, and limitations of application. Therefore, it is required to develop a front wall with a simple construction and a wide range of applications.

On the other hand, reinforced concrete retaining wall or reinforced earth block retaining wall, which is the most used in Korea, is exposed to the surrounding environment throughout the public period as the exposed surface is concrete product, and the secondary environment is infringed by corrosion of reinforcing steel and concrete as the main resistance material. More environmentally friendly retaining wall technology development is urgently needed. Environmentally friendly natural materials or vegetation retaining walls that can be planted are introduced as mesh wall, gabion (gebion) and vegetation back (RSS) retaining walls, but the high construction cost and complex construction methods including development costs make it difficult to commercialize them. have. Therefore, the development of a simpler structural system is required, and the simplification of the construction method is also considered.

Road development and complex development are being actively carried out in the era of localization, which is being promoted in Korea, and slope reinforcement and retaining wall using concrete, which is an environmental inhibitor, are constructed on many slopes and slopes. However, the vegetation bag, the mesh wall retaining wall, etc. have the advantage that the vegetation is possible, but the air is long and it is not activated due to the high construction cost compared to the structural stability.

Accordingly, an object of the present invention is to provide an eco-friendly vegetation retaining wall using a vegetation rebar block bag and a rebar block having eco-friendliness that is economical and vegetable by shortening the air with structural stability and light weight material and a simple construction method.

In the following the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the embodiments presented are exemplary for a clear understanding of the present invention is not limited thereto.

1 is a perspective view of a rebar block 10 applied to a vegetation rebar block bag according to an embodiment of the present invention, Figure 2 is a view showing the manufacturing procedure of the rebar block 10, Figure 3 It is a perspective view of the vegetation rebar block bag 1 showing the state in which the natural mesh 20 is installed in the rebar block 10.

As shown in FIGS. 1 to 3, the vegetation rebar block bag 1 includes a rebar block 10. Reinforcing block 10 is manufactured in the form of a rectangular box (cuboid) with a six-sided open. The reinforcing block 10 is made of four deformed reinforcing bars 10a, 10b, 10c, and 10d in this embodiment.

The deformed reinforcing bars 10a, 10b, 10c, and 10d are all approximately 'c' shaped and manufactured with the same structure. The thickness of the deformed bar can be around 16mm in diameter. Looking at the structure of any one of the deformed reinforcing bars (10a), the cross section 101, the vertical section bent vertically at both ends of the cross section 101, the connecting portion bent vertically at each end of the longitudinal section (102, 102) It consists of (103,103). At this time, the horizontal portion 101 and the longitudinal portion (102, 102) is located on the same plane. The length of the transverse portion 101 forms the basic unit length of the rebar block 10, and the longitudinal portions 102 and 102 determine the width and height of the rebar block 10. The connecting portions 103 and 103 are portions for connecting the deformed reinforcing bars 10a, 10b, 10c, and 10d with the mutual wire 15. The length of the connecting portions 103 and 103 is relatively shorter than the length of the longitudinal portions 102 and 102.

Such deformed reinforcing bars (10a, 10b, 10c, 10d) are arranged in a right angle direction in order from each other in the order of (a) to (d) of Fig. 2 overlapping parts 103, 103 and longitudinal ends 102, 102 after overlapping parts To bind by forcibly tied to the iron wire (15). Therefore, the deformed reinforcing bars (10a, 10b, 10c, 10d) is fixed to each other via the iron wire 15 is made to assemble easily. At this time, the longitudinal ends 102 and 102 of the third deformed bar 10c disposed on the upper surface side are seated on the cross section 101 of the fourth deformed bar 10d to receive the force of the horizontally placed deformed bar 10c. Preferably, the vertically disposed rebar 10d is supported.

As described above, the rebar block 10 may be manufactured as the deformed rebars 10a, 10b, 10c, and 10d having the same size and structure, and thus may be easily manufactured and the manufacturing cost may be reduced.

The rebar block 10 is provided with a natural mesh 20 as shown in FIG.

Natural mesh 20 is surrounded around the slope of the front and rear, left and right except for the upper and lower surfaces of the reinforcing block 10. The natural mesh 20 is in the form of a net woven with natural fibers to help prevent the loss of soil to be filled in the interior of the reinforcing block 10 and at the same time help the vegetation of vegetation. Natural mesh 20 is, for example, twisted natural fiber extracted from the coconut shell is woven into a rope shape, and then woven in a mesh shape is preferably composed of a woven mesh. This is because coconut mesh has excellent water resistance and strength, and is suitable for soil preservation and plant growth, and can prevent erosion or collapse of slopes, and promote greening.

It includes a fixing means for fixing the natural mesh 20 to the rebar block (10). The fixing means may be known tie bands or steel wires. The tie band or the iron wire is inserted into the eye hole of the natural mesh 20, and then connected to the reinforcing bars 10a, 10b, 10c, and 10d, and the natural mesh 20 is fixed to the rebar block 10.

On the other hand, the vegetation rebar block bag (1) is filled with soil, seeds, fertilizer inside the natural mesh 20. At this time, the seed may be any one selected from the group of ivy plants, vine plants, grasses and the like selected from the ivy, vine rose, creepy vine. Fertilizers, including organic fertilizers may be selected that are suitable for the vegetation. Soil is a low nutrient outflow may be a single, or a mixture of these, such as masato, red octopus, side leaf soil.

Table 1 below shows the germination rate, growth length and vegetation density of the grass shown in the vegetation rebar block bag (1) for each embodiment when the seed is grass.

 soil  seed  Fertilizer  Germination rate (%)   Growth length (cm)  Vegetation Density (%) Example 1     One    One    One      75       4      70 Example 2     One    2    2      80      5.5      80 Example 3     One    3    3      85       7      90

* Soil, seed, and fertilizer are weight ratios in terms of weight according to unit volume.

As can be seen in Table 1 above, when the soil, seeds (grass) and fertilizer are filled with a weight ratio of 1: 3: 3, it can be seen that germination rate, growth length and vegetation density were the best.

The vegetation reinforcement block bag 1 configured as described above is laminated after constructing the foundation concrete 100 on the ground on which the retaining wall is constructed, as shown in FIGS. 4 and 5 to form an environmentally friendly retaining wall. At this time, by using the backfill of the grid 110 and reinforcement soil 120 is constructed so that the vegetation rebar block bag 1 is not subjected to earth pressure. At this time, the vegetation rebar block bag (1) is stacked without overlapping in the transverse direction as shown in Figure 4, or the rebar block 10 as shown in FIG. ) Can be constructed.

At this time, it is possible to prevent damage of the retaining wall surface due to the peripheral contact during the common period by using the existing reinforced toe block up to 1m, which is the height at which the interference of human or surrounding traffic is possible at the base of the retaining wall. The uppermost layer is end reinforcement using a finishing block, and the U-pipe is installed on the back filling layer to block the penetration of the surface water into the retaining wall and to induce drainage. In addition, the stacking method of the rebar block bag (1) for vegetation can be modified in such a way as to secure the exposed surface as the vegetation retaining wall to increase the affinity with the surrounding environment and to reduce the environmental barrier of the artificial structure as much as possible.

Thus, using the vegetation rebar block bag 1 according to the present invention can be easily assembled and manufactured the rebar block 10, the man-hours are reduced and the workability is improved. In addition, the rebar block 10 is made of the same deformed bar is easy to manufacture and transport. In addition, natural mesh 20 to help promote the germination of seeds to increase the speed of growth and increase vegetation density.

On the other hand, as shown in Fig. 8 (a) may be formed in the fitting portion (102a, 102a) bent in the shape of the mountain or waveform for fitting coupling between the adjacent reinforcing bar blocks (10, 10). . Therefore, as shown in (b), the neighboring reinforcing bar blocks 10 and 10 are coupled through the fitting parts 102a and 102a so that there is no fear of positional deviation during or after construction, thereby improving construction stability.
