Supports for Helical Piles and Anchors

Abstract

The present disclosure provides a lateral support for a shaft of a helical pile, the lateral support including a tubular portion for receiving the shaft and a plurality of fins extending from the tubular portion.

What is claimed is: 
     
         1 . A lateral support for a shaft of a helical pile, the lateral support comprising:
 a member having a hollow center portion that can receive the shaft of the helical pile so that the shaft of the helical pile is rotatable within the hollow center portion and independent of the member; and   a plurality of fins extending outwardly from the member.   
     
     
         2 . The lateral support according to  claim 1 , wherein the member has a circular cross-section. 
     
     
         3 . The lateral support according to  claim 1 , wherein each of the plurality of fins are permanently attached to the member or integrally formed to the member. 
     
     
         4 . The lateral support according to  claim 1 , wherein each of the plurality of fins are monolithically formed into the member. 
     
     
         5 . The lateral support according to  claim 1 , wherein each of the plurality of fins are substantially flat plates made of steel or galvanized steel. 
     
     
         6 . The lateral support according to  claim 1 , wherein each of the plurality of fins has a diagonal corner edge. 
     
     
         7 . A lateral support for a shaft of a helical pile, the lateral support comprising:
 a tubular member having a hollow center portion that can receive the shaft of the helical pile so that the shaft of the helical pile is rotatable within the hollow center portion and independent of the tubular member; and   a plurality of fins extending outwardly from the tubular member.   
     
     
         8 . The lateral support according to  claim 7 , wherein the tubular member has a circular cross-section. 
     
     
         9 . The lateral support according to  claim 7 , wherein each of the plurality of fins are permanently attached to the tubular member or integrally formed to the tubular member. 
     
     
         10 . The lateral support according to  claim 7 , wherein each of the plurality of fins are monolithically formed into the tubular member. 
     
     
         11 . The lateral support according to  claim 7 , wherein each of the plurality of fins are substantially flat plates made of steel or galvanized steel. 
     
     
         12 . The lateral support according to  claim 7 , wherein each of the plurality of fins has a diagonal corner edge. 
     
     
         13 . A helical pile kit comprising:
 a lead shaft having a head portion and an end portion; and   a lateral support having:
 a member having a hollow center portion that can receive the head portion of the lead shaft so that the lead shaft is rotatable within the hollow center portion and independent of the member; and 
 a plurality of fins extending outwardly from the member. 
   
     
     
         14 . The helical pile kit according to  claim 13 , wherein the member is a tubular member having a circular cross-section. 
     
     
         15 . The helical pile kit according to  claim 13 , wherein each of the plurality of fins are permanently attached to the member or integrally formed to the member. 
     
     
         16 . The helical pile kit according to  claim 13 , wherein each of the plurality of fins are monolithically formed into the member. 
     
     
         17 . The helical pile kit according to  claim 13 , wherein each of the plurality of fins are substantially flat plates made of steel or galvanized steel. 
     
     
         18 . The helical pile kit according to  claim 13 , wherein each of the plurality of fins has a diagonal corner edge. 
     
     
         19 . The helical pile kit according to  claim 13 , wherein the lead shaft has at least one helical plate mounted in the end portion of the lead shaft. 
     
     
         20 . The helical pile kit according to  claim 13 , further comprising at least one extension shaft attached to lead shaft. 
     
     
         21 . The helical pile kit according to  claim 20 , wherein the lead shaft and the at least one extension shaft is fabricated from steel or galvanized steel.
