Block for constructing reinforced earth wall

Abstract

A block for the construction of a reinforced soil segmental retaining wall. The block includes a front surface, a rear surface, left and right lateral surfaces, an upper surface having a pair of left and right reinforcement insertion grooves, and a lower surface opposite to the upper surface. A pair of anchor pin insertion bores are vertically perforated at left and right sides of the upper and lower surfaces so that anchor pins are inserted therethrough to connect vertically neighboring blocks. Also, a pair of through-passages are vertically perforated from the upper surface to the lower surface to be laterally spaced apart from each other by interposing a partition.

1 . A block for constructing a reinforced segmented retaining wall having reinforcements and anchor pins, the block comprising: 
 a) a front surface to form an exposed face of a retaining wall;    b) a rear surface to come into contact with reinforced soil backfill;    c) a first lateral surface;    d) a second lateral surface;    e) an upper surface;    f) a lower surface opposite said upper surface;    g) a plurality of anchor pin insertion bores being perforated from said upper surface to said lower surface so that an anchor pin can be inserted through at least one of said anchor pin insertion bores to connect a plurality of blocks together;    h) a plurality of through-passages which are perforated from said upper surface to said lower surface so that when said blocks are stacked one on top of the other in a staggered manner, an anchor pin can be inserted through an insertion bore in an upper block and then inserted into a through passage in a lower staggered block, while an anchor pin which is inserted into an opposite insertion bore extends through another through-passage of an underlying second block adjacent to said first underlying block; and    i) a plurality of reinforcement insertion grooves that are disposed on opposite sides of said through passages on said upper surface, said plurality of insertion grooves being adapted to receive a reinforcement, wherein said plurality of reinforcement insertion grooves have a trailing end at a rear surface of the block and a leading end at a front end of an associated one of said plurality of through-passages.    
   
   
       2 . The block as in  claim 1 , further comprising: 
 at least one partition wherein said plurality of through-passages are spaced apart from each other on either side of said at least one partition;    a reinforcement insertion groove formed at an upper surface of said block along a front end of said partition between said plurality of through-passages;    a reinforcement which is coupled to said block.    
   
   
       3 . The block as in  claim 1 , wherein said upper surface of said block has a force absorption recess formed from plurality of partial dents.  
   
   
       4 . The block as in  claim 3 , wherein said force absorption recess is formed in a center region of said upper surface.  
   
   
       5 . The block as in  claim 4 , wherein said force absorption recess further comprises a supporting protrusion disposed in a center region of said upper surface of said block, wherein said supporting protrusion is located so as to not contact a lower surface of an overlying block when said blocks are stacked one on top of the other to construct a straight or curved retaining wall.  
   
   
       6 . The block as in  claim 1 , wherein each anchor pin insertion bore includes: 
 a first expanded portion having a relatively larger diameter; and    a second reduced portion having a relatively smaller diameter relative to said first expanded portion.    
   
   
       7 . The block as in  claim 1 , wherein each anchor pin insertion bore further comprises a tapered portion which is disposed between said first expanded portion and said second reduced portion.  
   
   
       8 . The block as in  claim 1 , wherein said plurality of insertion grooves extend forward from a rear surface of said block to a center region of said block by passing through said through-passages while extending in a curved manner.  
   
   
       9 . The block as in  claim 1 , further comprising a plurality of laterally protruding wings which are formed at rear ends of said lateral surfaces of the block, wherein said wings have cutting slots formed at rear corners of said block and are coupled to a rear surface of said block.  
   
   
       10 . An assembly forming a retaining wall comprising: 
 a) a plurality of blocks, wherein each block comprises: 
 i) a front surface to form an exposed face of a retaining wall;  
 ii) a rear surface to come into contact with reinforced soil backfill;  
 iii) a first lateral surface;  
 iv) a second lateral surface;  
 v) an upper surface having a pair of insertion grooves for the insertion of a reinforcement;  
 vi) a lower surface opposite said upper surface;  
 vii) a plurality of anchor pin insertion bores being perforated from said upper surface to said lower surface;  
 viii) a plurality of through-passages which are perforated from said upper surface to said lower surface; and  
 ix) a plurality of reinforcement insertion grooves that are disposed on opposite sides of said through passages;  
   b) a plurality of anchor pins wherein when said blocks are stacked one on top of the other in a staggered manner, at least one anchor pin is coupled to at least two of the blocks through an insertion bore in an upper block and then extending into a through-passage in a lower staggered block, while at least one additional anchor pin is inserted into an opposite insertion bore extends through another through-passage of an underlying second block adjacent to said first underlying block; and    c) at least one reinforcement wherein said plurality of insertion grooves are adapted to receive said reinforcement, wherein said plurality of reinforcement insertion grooves have a trailing end at a rear surface of the block and a leading end at a front end of an associated one of said plurality of through-passages.
