Structure to prevent soil loss in slope of river and coast and installation method thereof

Abstract

This application relates to a structure for preventing soil loss in slopes of a river and a coast. In one aspect, the structure includes a body part made of concrete, a plurality of first leg parts connected to a first end of the body part and arranged on a first plane by extending therefrom in longitudinal directions of the first leg parts, and a plurality of second leg parts connected to a second end of the body part and arranged on a second plane perpendicular to the first plane by extending therefrom in longitudinal directions of the second leg parts. The structure may further include a first reinforcement part provided by protruding outward from the body part, a second reinforcement part provided on a portion of each of the first leg parts by protruding outward therefrom, and a flowing water induction part provided as a shape of a channel.

What is claimed is: 
     
         1 . A structure to prevent soil loss in slopes of a river and a coast, the structure comprising:
 a body part made of concrete;   a plurality of first leg parts connected to a first end of the body part and arranged on a first plane by extending therefrom in longitudinal directions of the first leg parts;   a plurality of second leg parts connected to a second end of the body part and arranged on a second plane perpendicular to the first plane by extending therefrom in longitudinal directions of the second leg parts;   a first reinforcement part provided by protruding outward from the body part such that the first reinforcement part surrounds the body part to which each of the first leg parts and each of the second leg parts are connected;   a second reinforcement part provided on a portion of each of the first leg parts by protruding outward therefrom; and   a flowing water induction part provided as a shape of a channel defined by the second reinforcement part and configured to induce a flow of flowing water.   
     
     
         2 . The structure of  claim 1 , wherein each of the plurality of first and second leg parts extends to have an angle preset in a longitudinal direction thereof. 
     
     
         3 . The structure of  claim 1 , wherein the flowing water induction part is configured as a cross-shaped channel by the second reinforcement part relative to an inflection point of a front center of each of the first leg parts and induces a flow of flowing water. 
     
     
         4 . The structure of  claim 1 , wherein the first reinforcement part is configured as a closed or semi-closed type. 
     
     
         5 . The structure of  claim 1 , further comprising:
 pulling protrusion parts having shapes tapered inward to have shapes of convex wedges formed respectively on a lower end of the body part, an extension line of an axis of the body part, and the first and second leg parts.   
     
     
         6 . The structure of  claim 5 , wherein the pulling protrusion parts are configured as wedge-shaped blocks and upper and lower parts thereof are connected to each other to strengthen interlocking therebetween. 
     
     
         7 . An installation method of a structure to prevent soil loss in slopes of a river and a coast, the method comprising:
 forming at least one pulling protrusion part on a preset position of the structure of  claim 1 ;   moving a position of the structure to a preset position by hanging a rope on the pulling protrusion parts and pulling the structure after the forming of the pulling protrusion parts;   arranging the structure such that the flowing water induction part of the structure which is being moved through the moving of the position of the structure faces a front of a river or a coast; and   piling a plurality of structures on each other to be installed by repeating the moving of the structure position and the arranging of the structure.
