Geogrid

Abstract

Disclosed is a geogrid comprising a sheet main body formed with a plurality of through holes through which soil passes; at least one connector protruded from a surface of the sheet main body; and at least one accepter positioned opposite the connector and accepting the connector of another geogrid. With this configuration, the geogrid can be conveniently, carried, maintained and constructed, and is improved in durability.

What is claimed is:  
     
         1 . A geogrid comprising: 
 a sheet main body formed with a plurality of through holes through which soil passes;    at least one connector protruded from a surface of the sheet main body; and    at least one accepter positioned opposite the connector and accepting the connector of another geogrid.    
     
     
         2 . The geogrid according to  claim 1 , wherein the connector is provided one end part of the sheet main body, and the accepter is provided the other end part of the sheet main body opposite the connector.  
     
     
         3 . The geogrid according to  claim 2 , wherein on at least one surface of the sheet main body is provided a rib which is protruded in a direction perpendicular to a coupling direction of the geogrid.  
     
     
         4 . The geogrid according to  claim 3 , wherein the accepters are communicated with the through holes arranged adjacent to the end part of the sheet main body.  
     
     
         5 . The geogrid according to  claim 3 , wherein the accepters are partitioned off from the through holes arranged adjacent to the end part of the sheet main body.  
     
     
         6 . The geogrid according to  claim 4 , wherein each connector is comprised of a pin part being accepted to each accepter of another geogrid, and a head part extended at the free end of the pin part; and 
 the width of the head part is larger and smaller than minimum widths of the accepter and the through hole, respectively.    
     
     
         7 . The geogrid according to  claim 5 , wherein each connector is comprised of a pin part being accepted to each accepter of another geogrid, and a head part extended at the free end of the pin part; and 
 the width of the head part is larger and smaller than minimum widths of the accepter and the through hole, respectively.    
     
     
         8 . The geogrid according to  claim 4 , wherein each connector is comprised of a pin part being accepted to each accepter of another geogrid, and a head part extended at the free end of the pin part; and 
 the width of the head part is smaller than minimum width of the accepter.    
     
     
         9 . The geogrid according to  claim 5 , wherein each connector is comprised of a pin part being accepted to each accepter of another geogrid, and a head part extended at the free end of the pin part; and 
 the width of the head part is smaller than minimum width of the accepter.    
     
     
         10 . The geogrid according to  claim 6 , wherein each accepter has one of circular, elliptical, elongated, and polygonal shapes.  
     
     
         11 . The geogrid according to  claim 7 , wherein each accepter has one of circular, elliptical, elongated, and polygonal shapes.  
     
     
         12 . The geogrid according to  claim 8 , wherein the accepter has one of circular, elliptical, elongated, and polygonal shapes.  
     
     
         13 . The geogrid according to  claim 9 , wherein the accepter has one of circular, elliptical, elongated hole, and polygonal shapes.  
     
     
         14 . The geogrid according to  claim 2 , wherein the sheet main body and the connectors are made from metallic material, and the connectors are welded to the sheet main body.  
     
     
         15 . The geogrid according to  claim 2 , wherein the sheet main body and the connectors are made from a synthetic resin as one body.
