Abstract

The present invention provides an ecological block and a method for constructing an ecological vegetation bank protection wall and an ecological vegetation retaining wall using such an ecological block. In the ecological block according to the present invention, a truncated conical projection and a corresponding groove is provided at the upper and lower parts of the block body of said ecological block respectively, a channel-shaped space (groove) in which water grasses are planted is provided at either side of the block body of said ecological block, and traveling passages for amphibious animals and insects and grooves for absorbing noise are provided at the front part of the block body of the ecological block. With the present invention as mentioned above, it is possible to preserve the ecological environment since excellent spawning and inhabitable spaces for amphibious animals and insects are provided.

       5 . An ecological block for constructing a retaining wall especially on the cut-area or the cut-slope of a road, wherein at least one truncated conical projection adapted for convenient piling up a block structure on another block structure is provided at the upper part of the block body of said ecological block; at least one groove in which said truncated conical projection is engaged is provided at the lower part of the block body of said ecological block; a channel-shaped space in which stones are filled and trees and grasses are planted during the construction of the retaining wall is provided at either side of the block body of said ecological block; and a channel-shaped space adapted for reducing the noise due to the travel of a vehicle during the construction of the retaining wall is provided at the front part of the block body of said ecological block, said channel-shaped groove provided at the front part of the block body of said ecological block being communicated with said channel-shaped space provided at either side of the block body of said ecological block.  
   
   
       6 . An ecological block for constructing a retaining wall especially on the cut-area or the cut-slope of a road, wherein at least one truncated conical projection adapted for convenient piling up a block structure on another block structure is provided at the upper part of the block body of said ecological block; at least one groove in which said truncated conical projection is engaged is provided at the lower part of the block body of said ecological block; a channel-shaped space in which stones are filled and trees and grasses are planted during the construction of the retaining wall is provided at either side of the block body of said ecological block; and V channel-shaped grooves adapted for reducing the noise due to the travel of a vehicle during the construction of the retaining wall are provided at the front part of the block body of said ecological block approximately in the form of a diamond.  
   
   
       7 . A method for constructing an ecological vegetation bank protection wall using an ecological block, the method comprising the steps of: 
 depositing and curing fundamental concrete on the readjusted river bed at a riverbank;    spreading a thread sheet for preventing overflow of soil and sand along the upper part of said fundamental concrete and the slope of said riverbank;    providing a first stack of ecological blocks on said fundamental concrete approximately up to a half of the total vertical height of the slope of said riverbank, each of said ecological blocks including a truncated conical projection and a corresponding groove provided at the upper and lower parts of the block body of said ecological block respectively, a channel-shaped space provided at either side of the block body of said ecological block, and traveling passages for amphibious animals and insects provided at the front part of the block body of said ecological block;    filling relatively large stones in the space between the rear surfaces of said first stacked blocks and the slope of said riverbank where said thread sheet is spread to stabilize the stacking state;    providing a second stack of ecological blocks similar to said first stacked blocks in series on said first stacked blocks up to the upper end of the slope of said riverbank;    spreading a thread sheet closely on the rear surfaces of said second stacked blocks and filling pebbles, soil and sand in the space between the rear surfaces of said thread sheet and the slope of said riverbank to stabilize the stacking state; and    filling stones, soil and sand and planting water grasses in a closed space formed between the neighboring blocks by the channel-shaped spaces provided at the sides of said ecological blocks of said riverbank formed by said first and second stack.
