Description

[0001] The present invention relates to a vegetation panel, a reinforced earth retaining wall structure including the same,

The present invention relates to a vegetation block capable of recording a high-grade slope or various vertical walls generated by cut soil or embankment in a forward direction, and a construction method thereof.

Slopes such as roads and riverside slopes or crevices will be used to stabilize the slopes and to record them in order to prevent safety accidents caused by loss and collapse of the slopes and to improve the landscape.

In recent years, various efforts have been made to make vertical walls environmentally friendly by recording on various types of vertical walls. Examples of such vertical walls include vertical walls made of cut slopes or slopes perpendicular to the ground, and walls of large buildings.

Various methods are proposed for recording slopes. For example, in Korean Patent No. 10-1231040, there is a method of constructing vegetation retaining wall for recording a slope or a slope of a castle land, wherein a vegetation panel capable of controlling vegetation and slope is used to construct a steep slope surface, The method comprising the steps of:

However, the conventional techniques for enabling the slope recording by using the panel or the block have a very limited variety of plants for recording. In the case of a slope with a slope of more than 70 ° or a vertical plane, the continuous supply of water is not smooth and it can not grow except for certain kinds of plants such as vines and ferns.

In order to solve this problem, it may be considered to supply water artificially to the vegetation plant. However, in case of the civil retaining wall installed on the road side or the site, it is very difficult to supply moisture by the installation environment. There is a problem that the installation cost is very high even if it is installed, resulting in poor economical efficiency.

In addition, due to the toxicity of the concrete forming the panel or block, it is very difficult to keep the greening continuously.

In addition, when the front surface of the retaining wall is formed only by the vegetation panel, the inclination angle can not be formed beyond a certain angle in terms of vegetation or stability, and thus it is inevitably limited.

On the other hand, a reinforced soil retaining method is used for constructing a retaining wall having a steep slope inclination. The reinforced earth retaining wall is composed of a block wall provided on the front side and a reinforcing material laid between the backing soil on the rear side and the backing soil, The force against the external force or the earth pressure is increased.

However, the band-type fiber reinforcing materials used for the reinforced earth retaining wall often have insufficient frictional resistance with the soil, and the length of the reinforcing material is often increased more than necessary when the stability is examined. Of course, it is possible to increase the friction resistance by extending the length of the fiber reinforcing material, but this increases disadvantage in terms of workability and economical efficiency.

The reinforced earth retaining wall structure according to the present invention includes a composite retaining wall formed by mixing a vegetation panel 30 erected at a predetermined inclination angle and a front block 10 erected vertically or at an angle close to the vegetation panel 30, The front block 10 and the vegetation panel 30 may be alternately stacked as shown in FIG. 15, as shown in FIG. 15, or may be composed of a composite retaining wall where the vegetation panel 30 is positioned between the two separated front blocks 10.

By alternately stacking the front block 10 and the vegetation panel 30 extending in an orthogonal direction in comparison with a case where a plurality of sloping vegetation panels 30 are laminated in this manner, It is possible to increase the land use rate through the construction, and also to improve the beauty through the new type of retaining wall structure.

Hereinafter, a method of constructing the reinforced earth retaining wall structure according to the present invention will be described in detail.

First, the worker selects the floor of the place where the retaining wall is to be constructed, and after finishing it, the foundation work is done. The foundation can be made by fixing the base part (A) of the light concrete to the ground. At this time, the jaw can be formed in case the bottom end is pushed outward due to external force such as earth pressure after constructing the reinforced earth retaining wall. Basic stage)

Next, as shown in Fig. 2, the front block 10 is seated at the lowest end. (Block Installation Step) Of course, the panel mounting step to be described below is preceded and the vegetation panel 30 is installed at the bottom of the front block 10 It is possible.

Next, the worker installs the strip-shaped stiffener 200 in the rear of the front block 10. (Stiffener Staging Step) Although the strip stiffener 200 may be located between the front blocks 10 to be stored, Is fixed to the front block (10) through a fixing piece (300).

At this time, the band-shaped stiffener 200 should be installed such that an upward inclined portion of the resistance portion 255 faces the front block 10. This is because the band-shaped stiffener 200 is attached to the front block 10 In order to allow the resistance portion 255 to have a large resistance force thereto. Of course, when the structure of the resistance means 250 of the band-shaped stiffener 200 is made bidirectional as shown in the embodiment shown in Fig. 10, the installation direction of the band-shaped stiffener 200 is not provided.

The staple stiffener 200 is inserted into the first slot 330 of the stationary piece 300 and passes through the first slot 330 of the stationary piece 300. After the staple stiffener 200 is inserted into the first slot 330 of the stationary piece 300, (340).

A fastener 350 is assembled to the fixing piece 300 to narrow the width of the fixing slot 320. In this process, the band-shaped stiffener 200 is pressed and fixed in the fixing slot 320 . In this state, the worker inserts the fixing piece 300 into the receiving space (not shown) of the front block 10. So that one end of the fixing piece 300 and the strip-shaped stiffener 200 connected thereto are naturally fixed. Therefore, the worker does not need to wrap the front block 10 in order to fix the band-shaped stiffener 200 to the front block 10.

Then, another front block 10 is stacked on top of the front block 10 and a new backing soil B is laid on the rear side of the front block 10 to cover the upper portion of the staple stiffener 200 installed in advance (Laying step) The soil backbone is finished and the reinforcing soil retaining wall is formed as the block installing step or the dirt laying step is repeatedly performed.

Of course, the installation of the strip-shaped stiffener 200 and the step of installing the backfill soil B may be reversed. That is, after the backbone soil B is installed on the rear side of the front block 10, the strip-shaped stiffener 200 may be placed thereon.

A vegetation panel 30 is installed on the upper part of the front block 10. Panel Mounting Step The vegetation panel 30 may be installed in a direction slightly inclined from the ground surface, have.

After the vegetation panel 30 is installed on the front block 10, the vegetation mat 40 is installed on the back surface of the vegetation panel 30. (Mat Installation Step) As shown in FIG. 3, The vegetation mat 40 is placed on the back surface of the vegetation panel 30 so that the vegetation plant P passes through the through holes 31 ' That is, since the vegetation space of the vegetation panel 30 is directly connected to the backside soil B and the vegetation mat 40 through the through-hole 31 ', the vegetation layer of the plant for greening P is the ground surface , And soil, and thus, the evaporation of water and the environment in which the roots grow can be simulated very similar to the natural state, so that the vegetation rate and the engraftment rate of the plant (P) for greening can be improved.

Next, in the same manner as the installation of the front block 10, the operator installs the strip-shaped stiffener 200 rearward of the front block 10. (Stiffener mounting step) The strip-shaped stiffener 200 is installed on the vegetation panel 30, but it is fixed to the vegetation panel 30 through the fixing piece 300 in the present invention.

More precisely, one end of the band-shaped stiffener 200 is coupled to at least one of the upper plate 32 and the lower plate 31 provided on the vegetation panel 30, (Not shown) which is located between the first and second movable members 31 and 31. The stiffener 200 is installed in the same manner as the front block 10, and therefore, the stiffener 200 will be omitted.

Then, another front block 10 is stacked on top of the front block 10 and a new backing soil B is laid on the rear side of the front block 10 to cover the upper portion of the staple stiffener 200 installed in advance (Laying step) The soil backbone is finished and the reinforcing soil retaining wall is formed as the block installing step or the dirt laying step is repeatedly performed. FIG. 1 shows the shape of the reinforced earth retaining wall constructed through such steps.

2 and 3, the vegetation port 36 of the vegetation panel 30 protrudes forward of the panel frames 31 and 32 so that the vegetation port 36 is protruded forward Provide a vegetation space for vegetation (P) for greening. That is, the vegetation for vegetation P grows in the vegetation space formed by the vegetation port 36. This is because the vegetation plant P does not grow in the direction orthogonal to the outer surface of the vegetation panel 30 or the retaining wall , It means that the lower part of the vegetation port 36 can be naturally grown upward as a general direction in which the plant grows as a kind of ground. Therefore, it is possible to record in the structure of the retaining wall having a relatively rapid slope.

As shown in FIG. 3, by forming the angle lower than the angle of repose of the soil through the protruding structure of the vegetation port 36, it is possible to reduce soil and soil leaks even at the beginning of the construction before the front surface is reinforced In the case of natural excellence, the water does not flow down from the front but the water is transferred in the direction of the root of the plant, which is on the back side of the retaining wall.

In addition, since the passive friction resistance strip type stiffener constituting the reinforced earth retaining wall can be connected to the vegetation panel 30 to use the high strength vegetation panel 30, the inclination angle of the retaining wall structure can be made larger, and the stiffener 200 ) Is shortened, and the length of the backfill soil (B) and the amount of excavated soil are also decreased.

Also, it is needless to say that the binding force due to the weight of the front block 10 stacked up and down in the construction process is also added, so that the band-shaped stiffener 200 can be more firmly fixed.

When the earth pressure to be horizontally changed due to the natural environment or a specific external environment is large, the retaining wall formed by the front block 10 receives a force externally. In this process, The stiffener 200 connected to the front block 10 is also subjected to a force pulled outward.

However, the strip-shaped stiffener 200 according to the present invention is provided with the resistance means 250 and has a large frictional force with the backfill soil B, and this frictional force is generated by the stiffener 200 on the front block 10 The larger the force is received in the direction of the retaining wall. Accordingly, the pull-out resistance of the strip-shaped stiffener 200 is greatly improved, and the retaining wall can be stably maintained. Accordingly, the inclination angle of the retaining wall can also be designed to be relatively large.
