Title:
ガイド管ボルト抜き工具およびそのガイド管ボルト抜き工具を用いたガイド管ボルト抜き方法。
Document Type and Number:
Japanese Patent JP7450401
Kind Code:
B2
Abstract:
To solve such a problem that a damaged CV cable must be repaired or replaced when the CV cable is damaged due to a tooth such as a grinder or the like, since cable guide tubes are cut using the grinder or the like, in replacement work of conventional cable guide tubes.SOLUTION: According to the present invention, a bolt 7a can be made to be easily extracted from a bolt insertion hole 5b by pressing a tip of the bolt 7a with a bolt-pressing pin 12 having a shape insertable to the bolt insertion hole 5b from the tip. Accordingly, the bolt 7a can be surely extracted from the bolt insertion hole 5b even though a cable guide tube 5 and the bolt 7a are fixedly attached to each other via corrosion of the cable guide tube 5, and thus replacement of the two-split cable guide tube 5 covering an outer peripheral surface of a power cable 2 laid from an underground electric conduit line 1 into a manhole basement 3a can be facilitated.SELECTED DRAWING: Figure 6
