<p><P>PROBLEM TO BE SOLVED: To provide a split type jacking pipe for a pipe jacking method, which can increase axial shearing stress of a cylindrically joined joint part, even in the use of a small number of connecting members. <P>SOLUTION: This jacking pipe is a hollow cylindrical pipe for use in the pipe jacking method wherein a tunnel is formed while a hollow cylindrical pipe made of concrete is pushed out into ground; a pair of half bodies 2a and 2b, which is formed in such a shape that the cylindrical pipe is split into two half cylinders, is mutually joined together and cylindrically assembled; and jacking-force transfer joining surfaces 3c, which are joined to each other in the axial direction of the cylindrical pipe, are provided on a joint surface 3 between the respective half bodies 2a and 2b. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
