step fourteen, sectional translation construction is adopted, when the translation construction is started, a support bracket is inserted into a reserved hole to bear the reverse thrust transmitted by a horizontal jack, a limiting plate and a cover plate prevent the translation device from overturning, the horizontal thrust is provided by the horizontal jack to finish a pushing stroke, a sliding steel plate overturns forwards, and after the horizontal jack slides to a specified position, the bottom of a sliding foot is separated from the sliding steel plate through jacking, so that the first section of translation construction is finished; removing the cotter pin, rotating the support bracket to leave the reserved hole, moving the translation support to the next reserved hole and correspondingly fixing the cover plate on the ground, and performing the next section of translation construction; and (5) the circulation is repeated, and the translation construction of the existing building is realized.
7. The construction method according to claim 6, further comprising the step fifteen: and constructing a steel support between the wall clamping beam and the lower tray beam, ensuring the structural stability, and removing the horizontal jack, the sliding foot and the sliding steel plate.
8. The construction method according to claim 6, further comprising the step of sixteen: and constructing a gap filling structure between the upper tray beam and the track beam, maintaining to the designed strength, and removing all steel supports and the wall clamping beam.
9. The construction method according to claim 6, wherein the height of the runner is manufactured according to a modulus of 30mm, and the bottom elevation is adjusted by placing a steel plate with standard thickness between the upper part of the runner and the embedded part.
