An extended head pile with inside and outside reinforcement

Abstract

Disclosed herein is a head-extended pile with inside and outside reinforcements for supporting load of a structure. The head-extended pile includes a reinforcement part with the same length or area extending right and left with respect to a diameter of the pile provided at the front end of the pile so that a supporting force of the pile is increased, and a durability of the pile is improved by hammering after drilled piling. When the head-extended pile is applied according to the present invention, it improves the stability of proof stress of the pile and construction workability, and better economic efficiency is expected.

1 . A head-extended pile with inside and outside reinforcements for supporting load of a structure, comprising:
 a first head portion having a first right part and a first left part extending right and left with respect to a central axis of a first supporting wall, wherein the length of the first left part is equal to that of the first right part;   a second head portion having a second right part and second left part extending right and left with respect to a central axis of a second supporting wall, the length of the second left part is equal to that of the second right part, wherein a circular structure is symmetrically formed by the first and the second supporting walls and the first and the second head portions;   a hammering surface provided on the top surface of the circular structure; and   a central borehole formed between the first head part and the second head part.   
   
   
       2 . A head-extended pile with inside and outside reinforcements for supporting load of a structure, comprising:
 a first head portion having a first left part and a first right part extending right and left with respect to a central axis of a first supporting wall, wherein the length of the first left part is equal to that of the first right part;   a second head portion having a second right part and second left part extending right and left with respect to a central axis of a second supporting wall, the length of the second left part is equal to that of the second right part, wherein a circular structure is formed symmetrically by the first and the second supporting walls and the first and the second head portions;   a hammering surface provided on the top surface of the circular structure;   a central borehole formed between the first head part and the second head part; and   wherein the first and the second head portions have a uniform thickness respectively.   
   
   
       3 . The head-extended pile as set forth in  claim 2 , wherein each of the first and second head portions includes inclined surfaces formed at both sides thereof. 
   
   
       4 . The head-extended pile as set forth in  claim 2 , wherein the uniform thickness is achieved by sequentially laminating a plurality of head portions. 
   
   
       5 . A head-extended pile with inside and outside reinforcement parts for supporting load of a structure, comprising:
 a first head portion extending right and left with respect to a central axis of a first supporting wall, wherein the first head portion has an inner surface and an outer surface, and the sum of the supporting power of the inside surface and that of the outside surface is same;   a second head portion extending right and left with respect to a central axis of a second supporting wall, wherein the second head portion has an inner surface and an outer surface, the sum of the supporting power of the inside surface and that of the outside surface is same, a circular structure is formed by the first and the second supporting walls and the first and the second head portions, and the supporting stress of the first and the second supporting walls and the first and the second head portions is symmetrical;   a hammering surface provided on the top surface of the circular structure; and   a central borehole formed between the first head part and the second head part.   
   
   
       6 . A head-extended pile with inside and outside reinforcement parts for supporting load of a structure, comprising:
 a first head portion extending right and left with respect to a central axis of a first supporting wall, wherein the first head portion has an inner surface and an outer surface, and the sum of the supporting power of the inside surface and that of the outside surface is same;   a second head portion extending right and left with respect to a central axis of a second supporting wall, wherein the second head portion has an inner surface and an outer surface, the sum of the supporting power of the inside surface and that of the outside surface is same, a circular structure is formed by the first and the second supporting walls and the first and the second head portions, and the supporting stress of the first and the second supporting walls and the first and the second head portions is symmetrical;   a hammering surface provided on the top surface of the circular structure; and   a central borehole formed between the first head part and the second head part; and   wherein the first and the second head portions have a uniform thickness respectively.   
   
   
       7 . The head-extended pile as set forth in  claim 6 , wherein each of the first and second head portions includes inclined surfaces formed at both sides thereof. 
   
   
       8 . The head-extended pile as set forth in  claim 6 , wherein the uniform thickness is achieved by sequentially laminating a plurality of head portions.
