Security barrier

Abstract

There is provided a strong, secure, inexpensive see-through security barrier. The security barrier includes a foundation, wherein at least a portion of the foundation is underground. The security barrier also includes a plurality of pipes. Each pipe is integrally formed with the foundation and extends generally upwardly from the foundation. Each pipe includes a cylindrical wall having a generally smooth exterior surface and a rigid lock seam extending about and along the length of the wall.

1 . A security barrier comprising:
 a foundation, wherein at least a portion of the foundation is disposed underground; and   a plurality of hollow pipes, each pipe having a pipe end embedded within the foundation such that each pipe extends generally upwardly from the foundation, each pipe being of single piece construction, wherein each pipe includes a cylindrical wall having a generally smooth exterior surface and a joint extending helically about and along the length of the wall.   
   
   
       2 . The security barrier of  claim 1 , wherein the joint is a rigid lock seam. 
   
   
       3 . The security barrier of  claim 1 , wherein the foundation is comprised of concrete. 
   
   
       4 . The security barrier of  claim 1 , wherein the foundation is comprised of a plurality of sub-foundations. 
   
   
       5 . The security barrier of  claim 1 , wherein the plurality of pipes are comprised of metal. 
   
   
       6 . The security barrier of  claim 5 , wherein the plurality of pipes are comprised of 12 gauge steel. 
   
   
       7 . The security barrier of  claim 1 , wherein the plurality of pipes are comprised of a plastic material. 
   
   
       8 . The security barrier of  claim 1 , wherein the plurality of pipes are generally evenly spaced apart. 
   
   
       9 . The security barrier of  claim 8 , wherein the distance between the centers of adjacent pipes is approximately two to four feet apart. 
   
   
       10 . The security barrier of  claim 1 , wherein each pipe is at least partially filled with concrete. 
   
   
       11 . The security barrier of  claim 1 , further comprising rebar integrally formed with the foundation and each pipe, the rebar being operative to enhance the strength of the barrier. 
   
   
       12 . The security barrier of  claim 1 , further comprising expanded metal coupled to and extending between at least two pipes. 
   
   
       13 . A method of forming a security barrier, the method comprising the steps of:
 (a) excavating a base;   (b) placing a hollow pipe within the base such that each pipe extends generally upwardly from the base, wherein each pipe includes a cylindrical wall having a generally smooth exterior surface and a joint extending helically about and along the length of the wall; and   (c) forming a foundation within the base, such that the pipe end is embedded within the foundation.   
   
   
       14 . The method of  claim 13 , wherein the joint is a rigid lock seam. 
   
   
       15 . The method of  claim 13 , wherein the foundation is comprised of concrete. 
   
   
       16 . The method of  claim 13 , wherein the foundation is comprised of a plurality of sub-foundations. 
   
   
       17 . The method of  claim 13 , wherein the pipe is comprised of metal. 
   
   
       18 . The method of  claim 17 , wherein the pipe is comprised of 12 gauge steel. 
   
   
       19 . The method of  claim 13 , wherein the pipe is comprised of a plastic material. 
   
   
       20 . The method of  claim 13 , wherein the pipe is at least partially filled with concrete. 
   
   
       21 . The method of  claim 13 , wherein the pipe include a pair of apertures formed on opposed sides of the cylindrical wall. 
   
   
       22 . The method of  claim 21 , further comprising the step of inserting rebar through the pair of apertures.
