The construction steps of this example are as follows:
put this embodiment on the bridge pier, wherein, base 7 is the stress surface, starts to set up in the sliding shoe 2 jacking piston 4 upwards pushes up the contact bridge in advance, then according to the direction that the bridge needs to rectify, the level rotates jacking jack 10, because base 7 with install swing antifriction ring 9 between the shell 1, so the horizontal turning force is very little jacking piston 4 contacts the bridge bottom just can manually be adjusted. After the deviation rectifying direction is positioned, the jacking piston 4 in the sliding shoe 2 is started to jack up the bridge upwards, then the jacking jack 10 is started to carry out horizontal jacking to push the sliding shoe 2 to translate on the base 7, and as the antifriction sliding plate 8 is arranged between the bottom of the sliding shoe 2 and the base 7, the friction coefficient between the sliding shoe 2 and the base 7 is only 0.05 at most, so that the horizontal jacking force is also very small. And stopping the operation until the translation system is pushed to a preset position. If the horizontal adjustment is needed again, the shell 1 is horizontally rotated, then the pushing jack 10 installed on the shell 1 also correspondingly horizontally rotates, and the construction is adjusted again when the pushing jack rotates to the direction of the needed horizontal deviation correction.
