Seam allowance connection makes tensioning cylinder (2) to form an entirety then using the fork ear for being bolted tensioning cylinder；
B: shoulder pole girder installation shoulder pole girder: is installed in tensioning cylinder upper end position；When installation, the slot of shoulder pole girder is covered in drag-line
On, shoulder pole girder is fixed by bolt, tension rod passes through from the circular hole of shoulder pole girder；
C: installation tension rod: the circular hole that tension rod initially passes through shoulder pole girder is then passed through to the through-hole for the case that casts anchor, is then being casted anchor
Fixture nut anchoring is installed at case；
D: jack is inserted in by installation jack from tension rod top, and jack base is adjacent to shoulder pole girder upper surface,
The fixed jack of fixture nut is installed and completes installation in jack top；Jack is symmetrically arranged on shoulder pole girder both ends.
E: cable tensios control: the external computer tensioning system control oil pump of jack makes jack pair tension rod carry out tensioning；
It when stretching force reaches Suo Lishi, relaxes at tensioning cylinder, screws bolt-nut, when stretching force to design force value, lock anchor
Gu nut completes tensioning process.
The beneficial effects of the utility model are: this tool structure is simple, operation is simpler, securely and reliably, fixing structure
Has the advantages that centering connection drag-line；During cable tension, the design feature of steel anchor box and conventional cable is had not been changed, very well
The respective advantage of both combinations.
