Reinforcing strip for supporting reinforced earth wall and its placement method

Abstract

Disclosed are a reinforcing strip for supporting a reinforced earth wall and a method for placing the same. A front end (F) of the reinforcing strip 10 is folded into halves and inserted into a reinforcing strip insertion groove 22 formed in a block 20 forming the surface of the reinforced earth wall so that the reinforcing strip 10 is directly connected to the earth wall construction block 20 without an anchor or an anchor pin, and a plurality of the reinforcing strips 10 are continuously or installed in a reinforced earth 50 in a zigzag shape, or individually buried under the reinforced earth 50 . When a plurality of the reinforcing strips 10 are continuously installed in the reinforced earth 50 in the zigzag shape, rear ends (R) of the reinforcing strips 10 are buried under the reinforced earth 50 under the condition that the rear ends (R) are folded into halves or are erected. A folding groove 16 is formed in a central portion of the reinforcing strip in the lengthwise direction so that the central portion of the reinforcing strip 10 has a smaller thickness than other portions of the reinforcing strip 10 , thereby allowing the front end to be folded into halves and inserted into the reinforcing strip insertion groove 22 of the block 20.

1 . A method for placing reinforcing strips for supporting a reinforced earth wall, in which front ends (F) of the reinforcing strips  10  are inserted into reinforcing strip insertion grooves  22  of blocks  20  forming the surface of the reinforced earth wall under the condition that the front ends (F) of the reinforcing strips  10  are folded into halves in the lengthwise direction to have a half width.  
   
   
       2 . The method as set forth in  claim 1 , wherein the reinforcing strips  10  are arranged on a reinforced earth  50  in a zigzag shape, and the front end (F) of the reinforcing strips are sequentially and continuously inserted into the reinforcing strip insertion grooves  22  of the neighboring blocks  20 .  
   
   
       3 . The method as set forth in  claim 2 , wherein rear ends (R) of the reinforcing strips  10  are folded in the widthwise direction, and the folded rear ends of the reinforcing strips are fixed to the reinforced earth  50  by temporary fixing nails  30  or fixed to resistors  40  by fixing pins  42 .  
   
   
       4 . The method as set forth in  claim 2 , wherein the rear ends (R) of the reinforcing strips  10  are erected in the lengthwise direction, and is buried under the reinforcing earth  50  or inserted into resistors  40  by fixing pins  42 .  
   
   
       5 . The method as set forth in  claim 1 , wherein the front ends (F) of the reinforcing strips  10  are independently connected to the reinforcing strip insertion grooves  22  of the blocks  20 , and rear ends (R) of the reinforcing strips are individually buried under a reinforced earth  50 .  
   
   
       6 . A reinforcing strip, for supporting a reinforced earth wall, comprising a plurality of polyester fabric bundles arranged in parallel and coated with polyethylene resin, 
 wherein a folding groove  16  is formed in a central portion of the reinforcing strip  10  in the lengthwise direction so that the central portion of the reinforcing strip has a smaller thickness than other portions of the reinforcing strip.    
   
   
       7 . The reinforcing strip as set forth in  claim 6 , wherein the folding groove  16  is formed in upper and lower surfaces of the reinforcing strip  10 .  
   
   
       8 . The reinforcing strip as set forth in  claim 6 , wherein protrusions  18  for displaying the length of the reinforcing strip are formed on the surface of the reinforcing strip  10  such that the protrusions  18  are separated from each other by a designated interval.
