It is shown in detail.

That is, FIG. 6 is a perspective view showing the rear portion of the retaining wall showing the construction of the retaining wall according to one embodiment of the present invention, and FIG. 7 is a perspective view showing the front portion of the retaining wall showing the construction of the retaining wall. 9 is a front perspective view of the retaining wall immediately after completion of construction according to the present invention, and FIG. 9 is a front perspective view of the retaining wall showing a state in which a herbaceous vegetation is formed on the retaining wall constructed by the present invention, and FIG. Fig. 11 is a front perspective view of a retaining wall showing a state in which wood vegetation is made in the retaining wall completed by the construction, and FIG. 11 is a side cross-sectional view of the retaining wall in a state in which the vegetation is made after completion of construction.

6 to 11, the retaining wall construction process of the present invention comprises the steps of firstly stacking at least two or more unit blocks vertically and uniting them with connecting pins (P); Second, the first construction step of lifting the unitized block (U) at once to build on the concrete foundation (C); Third, the reinforcement soil 70 is installed on the rear of the primary unitized block U, and the reinforcement 80 is connected to the 11th structured block U, and the reinforcement soil 70 is laid on the reinforcement soil 70. Compacting 70; Fourth, filling soil with the soil filling part 60 of the primary constructed block U and planting vegetation (sowing or transplanting of seeds); Fifth, vertically stacking at least two or more unit blocks and unitizing them with connecting pins (P); Sixth, a second construction step of constructing the second unit united block (U) to the left, right to intersect on the primary united block (U); Seventh, the reinforcement soil 70 is installed on the rear of the secondary structured block U, and the reinforcement body 80 is connected to the secondary structured block U to lay on the reinforcement soil 70 and reinforcement soil 70 Compacting); Eighth, filling the soil in the soil filling unit 60 of the block (U) secondly constructed and planting vegetation, including, the process after the second construction step is the secondary according to the height of the retaining wall The same process may be repeated from the construction stage.

The anchor 90 is preferably assembled in a state in which the block is inserted into the block for each required height when uniting the unit, but may be installed between the upper and lower blocks during the construction of the retaining wall.

Meanwhile, a non-woven drain filter 100 is installed at the rear of the overlapping portion of the block between the unit blocks U which are adjacent to the left and right to prevent the backfill soil 70 from being exposed to the front of the retaining wall. Only water can be drained to the front of the retaining wall, and as shown in FIG. 11, the drainage filter 100 is also extended to the inside of the earth filling part 60 inside the block U as it is. If rainwater flows into), only the rainwater is drained in front of the retaining wall by the drainage filter, and the loss of soil is effectively prevented.

As shown in FIG. 12, the retaining wall is constructed after the blocks are alternately constructed up and down. When the horizontally constructed block is subjected to shear force during the floating settlement of the ground, the block is absorbed by allowing the block to be tilted, and the corner portion of the lower block is the soil filling part of the lower block (60). ), And the edge of the lower block is prevented from entering into the external force absorbing grooves (61a, 63a), and the middle of the lower block is concentrated. Not because it will be prevented that the front end (cleavage) by half.

In addition, according to the construction method of the present invention, the height of the unitized block (U) is gradually lowered toward the upper portion of the retaining wall, so that the number of the soil inserts 60 exposed forwardly at the intersection between the unitized blocks is also large. Since the vegetation density can be increased, when the retaining wall is built on the inner side of the road, the retaining wall can be greened in the distance and harmonize with the surrounding natural landscape without disturbing the traffic of the vehicle up to a certain height.

In addition, when the block according to the present invention is constructed using the method of building the present invention, the soil filling unit 60 formed inside the united block U as shown in FIG. Deeply connected, it is possible to have strong rooting of vegetation, and furthermore, since the exposed part is minimized, the vegetation can be prevented from being killed during dry season. Soil of 60) is also interconnected with the reinforcement soil 70 in the rear at the lower end, so that the water supply to the vegetation and drainage of excess water can be effectively made.
