Triangle unit assembly block and method using same of building landslide preventing draining retaining wall

Abstract

A triangle unit assembly block comprises a body portion comprising mutually facing first and second side surfaces and mutually facing third and fourth side surfaces between a upper surface and a lower surface; a first fastening protrusion formed on the first side surface of the body portion; a second fastening protrusion formed on the second side surface of the body portion; a first fastening groove formed on the third side surface of the body portion; and a second fastening groove formed on the fourth side surface of the body portion, wherein the first and second fastening protrusions are disposed to correspond to each other and protrude in mutually opposite directions, and the first and second fastening grooves are disposed to be misaligned with one another to be concave in mutually facing directions.

1 . A triangle unit assembly block comprising:
 a body portion comprising mutually facing first and second side surfaces and mutually facing third and fourth side surfaces between a upper surface and a lower surface;   a first fastening protrusion formed on the first side surface of the body portion;   a second fastening protrusion formed on the second side surface of the body portion;   a first fastening groove formed on the third side surface of the body portion; and   a second fastening groove formed on the fourth side surface of the body portion,   wherein the first and second fastening protrusions are disposed to correspond to each other and protrude in mutually opposite directions, and the first and second fastening grooves are disposed to be misaligned with one another to be concave in mutually facing directions.   
     
     
         2 . The triangle unit assembly block of  claim 1 , wherein the area of the first side surface of the body portion is equal to the area of the second side surface of the body portion, and is larger or smaller than the area of the third or fourth side surface of the body portion. 
     
     
         3 . The triangle unit assembly block of  claim 1 , wherein the first and second fastening protrusions are formed on both sides respectively from the upper surface to the lower surface of the body portion, and a hemispherical protrusion line protruding in a perpendicular direction to the third side surface or the fourth side surface of the body portion is formed. 
     
     
         4 . The triangle unit assembly block of  claim 1 , wherein the first and second fastening grooves are formed along both inner sides respectively from the upper surface to the lower surface of the body portion, and a hemispherical groove line recessed in a perpendicular direction to the first side surface or the second side surface is formed. 
     
     
         5 . The triangle unit assembly block of  claim 1 , wherein the areas of the first and second fastening grooves are larger than the first and second fastening protrusions. 
     
     
         6 . The triangle unit assembly block of  claim 1 , wherein the first and second protrusions are fastened to a first fastening groove or second fastening groove of an adjacent assembly block. 
     
     
         7 . The triangle unit assembly block of  claim 1 , wherein a plurality of convex portions are formed to be disposed at regular intervals on the upper surface of the body portion. 
     
     
         8 . The triangle unit assembly block of  claim 7 , wherein, a plurality of convex portions are formed on the upper surface of the body part, and the upper and lower surfaces of the body portion are flat planes, and the side surface of the convex portion is an inclined surface. 
     
     
         9 . The triangle unit assembly block of  claim 8 , wherein between adjacent convex portions, the first and second fastening grooves are disposed. 
     
     
         10 . Method of building a landslide preventing draining retaining wall using a triangle unit assembly block comprising first and second fastening protrusions disposed to correspond to side surfaces mutually facing each other, and first and second fastening grooves disposed to be misaligned on side surfaces mutually facing each other, wherein the method comprises:
 forming a triangle unit assembly by inserting a first fastening protrusion of a first assembly block into a first fastening groove of a second assembly block, inserting a second fastening protrusion of a second assembly block into a first fastening groove of a third assembly block, and inserting a first protrusion of the third assembly block into a second fastening groove of the first assembly block;   forming a horizontal assembly by connecting at least two triangle unit assemblies in a horizontal direction; and   forming a structure while stacking adjacent triangle unit assemblies to be misaligned with each other, by stacking at least two horizontal assemblies in a vertical direction.
