Method for reinforcing piling, and piling

Abstract

The purpose of the present invention is to provide a method by which a piling is reinforced and stable support strength can be provided to a building. The method accordingly includes a step for removing a peripheral region of a buried piling, and exposing the piling, and a step for forming in the removed area a reinforcement layer surrounding the piling. Employing a reinforcement method of such description enables load from the building to be supported by the piling and the reinforcement layer. The reinforcement layer can be formed by laying crushed rock, sandbags, concrete, or mortar; pouring a hardening materials; or a combination thereof.

1 . A pile reinforcement method, comprising:
 a step for removing a peripheral region of a buried pile to expose the pile, and   a step for forming in the removed region a reinforcement layer surrounding the pile.   
     
     
         2 . The pile reinforcement method according to  claim 1 , wherein the reinforcement layer is formed by laying crushed stones, sandbags, concrete or mortar or by pouring in a solidification agent. 
     
     
         3 . The pile reinforcement method according to  claim 1 , further comprising:
 a step for attaching a flange member to the exposed pile, wherein   the step for forming the reinforcement layer brings the reinforcement layer into contact with the flange member.   
     
     
         4 . A pile buried in a ground, in which a reinforcement layer is provided near a surface of the ground, the pile comprising:
 a flange member that is provided to stand on a pile head or a peripheral surface of the pile and that contacts the reinforcement layer when the pile is buried in the ground.   
     
     
         5 . The pile according to  claim 4 , wherein the flange member is provided to surround the peripheral surface of the pile. 
     
     
         6 . The pile according to  claim 4 , wherein the flange member is provided to be perpendicular to the peripheral surface of the pile. 
     
     
         7 . The pile according to any one of  claim 4 , wherein a distance from a connection between the flange member and the pile to an outer edge of the flange member is 0.5 to 5.0 times larger than a diameter of the pile. 
     
     
         8 . The method according to  claim 1 , wherein
 the step for forming the reinforcement layer includes:
 a first crushed stone putting-in step for putting in crushed stones into the removed region, and 
 a first immobilizing step for packing the crushed stones put in by the first crushed stone putting-in step. 
   
     
     
         9 . The method according to  claim 8 , wherein
 the step for forming the reinforcement layer further includes:
 a second crushed stone putting-in step for putting in crushed stones further on the crushed stones packed by the first immobilizing step; and 
 a second immobilizing step for packing the crushed stones put in by the second crushed stone putting-in step.
