It will be desirable to form.

A more detailed description of one embodiment of the revetment block (1, 1 ') according to the present invention for structural slope stability of the revetment surface will be described in detail below.

For reference, the appearance of the rafting block (1, 1 ') is an embodiment of the rafting block according to the present invention, of course, various types of rafting block can be made of the material described below.

1) Material

The revetment block (1, 1 ') according to the present invention is made of a porous material in consideration of the vegetation potential and eco-friendliness to biological habitat.

The aggregates used are homogenized to a diameter of 13-16 mm, with 58-62% by weight of common crushed rock, 16-22% by weight of pozzolan and 16-22% by weight of bottom ash.

The crushed rock can be applied to the general gravel, preferably the crushed rock (crushed gravel) to a single particle of 13 mm to maintain the porosity 25%.

The pozzolan is a diatomaceous earth or diatomaceous earth aluminum material having little or no cement property, and when it encounters fine grains and encounters moisture, chemically reacts with calcium hydroxide at room temperature to form a compound having cement properties.

The pozzolanic is an igneous rock of the Cretaceous period about 100 million years ago, and is an aggregate having excellent acid resistance, corrosion resistance, heat insulation, durability, waterproofness, etc., and has antibacterial, deodorizing, water purification, and detoxification effects. It contains a large amount of trace elements and organic substances that are beneficial to the human body while producing beneficial effects on living organisms. The pozzolanic is applied to the same particles in addition to the crushed gravel to optimize the porosity of the revetment block (1, 1 '), and to facilitate the deposition of plants on the repose block (1, 1').

Pozolan is composed of the components shown in [Table 1].

Sio2 Al2O3 Fe2O3 MgO K2O Na2O CaO TiO2 MnO 68.9 15.6 4.74 1.24 3.55 1.66 0.36 0.62 0.01

In general, pozzolanic has a far-infrared emissivity of 0.927 (5-20 μm), a far-infrared energy of 3.74 × 10 ² (W / m ² · μm), 99.9% antibacterial function, and 90-96% deodorizing function.

On the other hand, coal is powdered at a coal-fired power plant and injected into the furnace at high speed with hot air, and most of the minerals contained in the coal are instantly burned in a suspended state at a temperature range of 1500 ± 200 ℃, above the melting point. do.

Here, 70 to 90% of the total ash filtered by the filter while passing through the combustion furnace together with the combustion gas is called fly ash.

On the other hand, 10 to 30% of the total ash solidified by sintering in the combustion furnace and hardened is called bottom ash. Here, since the bottom ash has a porous property, it is excellent in water-containing function and aeration efficiency, thereby helping the roots of the plant roots.

A binder is included for bonding the aggregate.

The binder consists of 55% by weight of white cement, 15% by weight of fly ash, and 30% by weight of blast furnace slag powder.

General Portland cement is very detrimental to plant growth because of its watertightness and strong alkali (pH 13) properties. Therefore, the raft block (1, 1 ') according to the present invention is a mixture of white cement, blast furnace slag powder and fly ash as a binder of the aggregate to lower the hydrogen ion concentration to weak alkali (pH 8 or less), through which the binder It is to facilitate the plant growth in the produced raft block (1, 1 ').

Subsequently, admixtures are included. The admixture for increasing strength is a high performance sensitizer, and polycarboxylic acid, naphthalene or lignin may be applied.

As a result, the shelter block according to the present invention is 55.9 to 56.1 wt% of crushed rock (crushed gravel), 13.9 to 14.1 wt% of pozzolan, 12.6 to 12.8 wt% of bottom ash, and 9.3 to 9.6 wt% of white cement, blast furnace slag Powders include 5.0-5.2 wt%, fly ash 2.5-2.7 wt%, admixtures 0.15-0.25 wt%. Preferably, 56.0% by weight of crushed rock (crushed gravel), 14.0% by weight of pozzolan, 12.7% by weight of bottom ash, 9.4% by weight of white cement, 5.1% by weight of blast furnace slag powder, 2.6% by weight of fly ash, admixture 0.2 wt% may be applied.

In the embodiment according to the present invention was configured a relief block in the formulation as shown in Table 2. For reference, Table 2 compares the components of the relief block according to the present invention and the components of the conventional relief block.

In the embodiment according to the present invention, four upper bodies 20 are arranged on the lower body 10 in two rows and two columns. Accordingly, the upper bodies 20 adjacent to each other are in contact with each other at one point, and the recessed space 22 is formed at the center of the four upper bodies 20.

On the other hand, since the lower body 10 is formed in a shape corresponding to the circular upper body 20, the central side of the side forms a concave shape inward and both sides of the side to form a protruding shape, the both ends of the recessed portion 11 and the convex portion, respectively (12) is formed so that the interlocking between neighboring shore blocks (1, 1 ') is made.

Subsequently, at one point of the lower body 10 in which the vegetation grooves 21 are formed, a vegetation space 13 is formed in communication with the vegetation groove 21, and the vegetation space 13 penetrates up and down to be planted on the surface. Plants can be exposed to the ground through the raft block (1, 1 ').

Here, the jaw is formed between the vegetation groove 21 and the vegetation space 13. After the revetment block (1, 1 ') according to the present invention is seated on the surface and is buried (earthed) by earth and sand as shown in Figure 4 (sectional view showing the installation of the revetment block according to the present invention), the upper body Except for the upper surface of (20), it is covered and covered with the soil. That is, since the earth and sand cover the jaw of the recess 22 and the vegetation groove 21 together with the weight of the revetment blocks 1 and 1 ', the revetment blocks 1 and 1' are stable on the inclined surface. It can be fixed.

Subsequently, the circular upper body 20 effectively prevents soil leakage while performing the function of confining the covered soil and forms an isolated recessed space 22 when the neighboring upper bodies 20 are disposed to be in contact with each other. This also has a structural function of effectively fixing the soil by trapping the covered soil.

As mentioned above, the revetment block (1, 1 ') according to the present invention forms a concave shape in the center of the side, the lower body 10 forms a shape corresponding to the upper body 20 of the circular donut shape Therefore, when connected to each other in a multi-row grooves are formed between the neighboring raft block (1, 1 ') as shown in Figure 3 (a plan view showing another embodiment of the raft block according to the present invention). As a result, the vegetation settlement rate is increased by forming various grooves penetrating up and down in addition to the vegetation space 13 of the revetment blocks 1 and 1 ', and the environment in which the habitat is favorable even in the environment where the revetment blocks 1 and 1' are constructed. Can be formulated.

In addition, since the cover is made stable in the entire shore bank (1, 1 ') except the upper end of the upper body 20, the space between the vegetation space 13 and neighboring shore blocks (1, 1'), etc. Of course, the plant is settled over the entire surface of the revetment block (1, 1 '), such as the vegetation groove 21 and the receding space 22 surrounded by the upper body 20, through which the plant growth proceeds throughout the dike It works. In addition, since the plants rooted and squeezed into the raft block (1, 1 ') perform the anchor function of the raft block (1, 1'), the embankment formed by the raft block (1, 1 ') according to the present invention is structural Stability also has a guaranteed effect.

3 is a plan view showing another embodiment of the raft block according to the present invention, will be described with reference to this.

The revetment blocks 1 and 1 ′ according to the present invention may be reinforced with reinforcing bars 14 to increase rigidity, and the ring 15 connected with the reinforcing bars 14 may be drawn out from each corner.

The ring 15 is a means for connecting the other neighboring eye block 1, 1 'by the linker 30 to each other, and can strengthen the cohesion between the eye block 1, 1' to direct integration. For reference, the ring 15 and the linker 30 may prevent corrosion through hot dip galvanizing treatment.

The above-mentioned shore block (1, 1 ') is a porous vegetation concrete structure that allows plant roots to settle smoothly on the original ground, and sufficient vegetation space in the block is achieved through efficient fusion between the original ground and the shore block (1, 1'). To protect and maintain the growth environment of indigenous organisms such as microorganisms, plants, insects, etc., the circular structure of the upper body 20 can achieve structural stability by preventing stress concentration dynamics, while minimizing the exposed area Through it is effective to maximize the harmony with the natural environment.
