RECONSTRUCTION METHOD AND RECONSTRUCTION DEVICE FOR EXISTING PIPE |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To enable cutting even when a reconstruction device meets a steel collar and a pouring socket and prevent operation of an excavator from being stopped due to jacking of a new pipe even when jacking the new pipe to enable smooth reconstruction of a pipe. <P>SOLUTION: A starting shaft and an arrival shaft are newly provided adjacent to respective inner sides of an existing manhole to be reconstructed. A freely running cutting machine provided with a plurality of rotary blades runs in the existing pipe from the starting shaft to cut the existing pipe and a connection member by the rotary blades. Filler is filled into a space in the existing pipe cut simultaneously with the cutting. The existing pipe after filling is crushed by the jacking type excavator, and the new pipe being a jacking pipe is jacked from the rear while excavating the existing pipe and filler to replace the existing pipe with the new pipe. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
