Embedded 25 tons of position earth anchor, two ground anchor locations and along 90 ° of settings of line direction, the angle of conducting wire projection and bracing wire is pressed
15 °~20 ° are arranged, and have buried earth anchor before unfolding conductor, and get out jack.After starting unwrapping wire, limp is led by planning installation
Stop traction behind the anti-tower position for kinking device of line immediately, the upper tower of high-altitude personnel installs that conducting wire is anti-to kink device, and by wirerope
Whereabouts wirerope is to ground after being connected by U-shaped ring, when starting to draw conducting wire, by ground staff simultaneously along the traction of conducting wire,
It pulls both ends wirerope and the anti-device that kinks of conducting wire is pulled to fixation position plan, after wirerope connection jack with being connected to ground
Anchor after stringing walking plate passes through next base tower position, fastens jack, adjusts jack height, it is ensured that almost the same with unfolding conductor sag
It or is slightly in pressed status.Unfolding conductor is completed, and when starting stringing, adjusts jack according to conducting wire sag, conducting wire reaches base
This sag and 6 phase sub-conductor sags it is almost the same after, the online dismounting six-multiple conductor of high-altitude personnel is anti-to kink device, continues secondary
Fining adjustment conducting wire sag simultaneously installs attachment.
The beneficial effects of the present invention are:
The present invention solves the problems, such as that six-multiple conductor unfolding kinks in the process, Ying is hit, can be smoothly complete in season of blowing
At unfolding conductor, reduces the security risk of the online separation sub-conductor of unfolding conductor process high and medium personnel, improve conducting wire exhibition
Efficiency and quality, and structure simple and flexible are put, easy to use, economy uses, and saves the construction period.
