Fig. 9 to Fig. 12 show states that the ecological vegetation bank protection wall or the ecological vegetation retaining wall is constructed according to a method for constructing the ecological vegetation bank protection wall or the ecological vegetation retaining wall using the ecological block according to the present invention, respectively; Fig. 9 and Fig. 10 illustrate states that an ecological vegetation bank protection wall is constructed using the ecological block according to the first preferred embodiment, and Fig. 11 and Fig. 12 illustrate states that an ecological vegetation retaining wall is constructed using the ecological block according to the third preferred embodiment. Referring to Fig. 9 and Fig. 10, a method for constructing an ecological vegetation bank protection wall using the ecological block according to the present invention will be described. First, fundamental concrete 120 is deposited and cured on the readjusted river bed at a riverbank. At this time, the upper part of the concrete 120 on which the ecological blocks are stacked is formed such that it is inclined at the slope rate of 1 :0.2 when the fundamental concrete 120 is deposited. It ensures that the inclination of the bank protection wall is 1 :0.5 after the construction is complete by stacking the ecological blocks because the front inclination of the front part of the ecological block 100 is 1 :0.3. After the fundamental concrete 120 has been cured, a thread sheet (construction fiber) 121 for preventing overflow of soil and sand is spread along the upper part of the fundamental concrete 120 and the slope of the riverbank. Next, on the fundamental concrete 120 approximately up to a half of the total vertical height of the slope of the riverbank are stacked firstly the ecological blocks 100 (Fig. 1), each of which includes a truncated conical projection 102 and a corresponding groove 104 provided at the upper and lower parts of the block body of the ecological block respectively, a channel-shaped space 105 provided at either side of the block body of the ecological block, and channel-shaped grooves 110 along which the amphibious animals and insects move provided at the front part of the block body of the ecological block. Next, relatively large stones (boulder) 122 is filled in the space between the rear surfaces of the first stacked blocks 100 and the slope of the riverbank where the thread sheet 121 is spread to stabilize the stacking state. After that, ecological blocks similar to the first stacked blocks 100 are stacked secondly in series on the first stacked blocks 100 up to the upper end of the slope of the riverbank. And then, a thread sheet 121 is spread closely on the rear surfaces of the second stacked blocks 100 and filling pebbles, soil and sand 123 in the space between the rear surfaces of the thread sheet 121 and the slope of the riverbank to stabilize the stacking state.
After the first and second stack is complete as mentioned above, stones, soil and sand are filled and water grasses 125 are planted in a closed space 124 formed between the neighboring blocks by the channel-shaped spaces provided at the sides of the ecological blocks 100 of the riverbank formed by the first and second stack. At this time, only stones are filled in a closed space 124' formed by the ecological blocks 100 submerged under the surface of the water in the river so that spawning and inhabitable spaces for amphibious animals are ensured. Of course, submerged plants, such as Hydrilla verticillata, Ceratophyllum demersum, Potamogeton crispus, Vallisneria asiatica, etc., may be planted among the stones. In this way, the construction of the ecological vegetation bank protection wall using the ecological block is complete.
If the bank protection wall is constructed as mentioned above, the water grasses 125 planted among the blocks 100 constitute a forest, resulting in that pro-environmental bank protection wall harmonized with the surrounding scenic beauty is constructed and the excellent spawning and inhabitable spaces for amphibious animals and insects are provided. Fig. 11 and Fig. 12 illustrate states that an ecological vegetation retaining wall is constructed according to a method for constructing the vegetation retaining wall using the ecological block according to the present invention, respectively. First, fundamental concrete 130 is deposited and cured on the edge of a road. At this time, it is possible to use a side ditch instead of the fundamental concrete if the side ditch is provided at the edge of the road when the road is paved.
After the fundamental concrete 130 has been deposited and cured, ecological blocks 500 (Fig. 5), each of which includes a truncated conical projection 102 and a corresponding groove 104 provided at the upper and lower parts of the block body of the ecological block respectively, and channel-shaped grooves 105 and 507 provided at either side of the block body of the ecological block and at the front part of the block body of the ecological block respectively for planting trees and grasses and reducing noise, on the fundamental concrete 130 up to a predetermined height. Next, a thread sheet 131 for preventing overflow of soil and sand is spread along the rear surfaces of the stacked ecological blocks 500. After that, soil and stones 132 are filled in the space between the rear surfaces of the stacked blocks 500 where the thread sheet 131 is spread and the cut-slope of the road to stabilize the stacking state. And then, stones, soil and sand are filled and trees and grasses 135, such as mountain willows, wild flowers, etc., are planted in a closed space 134 formed between the neighboring blocks by the channel-shaped grooves provided at the sides of the ecological blocks 500 of the retaining wall formed by the stack.
If the retaining wall is constructed as mentioned above, excellent landscape architecture can be obtained because desolation and monotony of the prior concrete retaining wall is avoided, and the noise can be reduced sharply because most of the noise due to the travel of a vehicle is absorbed by the jagged ecological blocks 500 and the trees and grasses planted between the blocks.
