Abstract

The invention discloses a damage-free quick mounting and dismounting temporary anchoring device and a damage-free quick mounting and dismounting temporary anchoring method, which belong to the technical field of swivel bridge construction and aims to solve the problem that the stability and safety of swivel construction are influenced due to failure of a temporary anchoring measure caused by the fact that the temporary anchoring measure is extremely easy to be pressed and yielded by adopting finish-rolled deformed steel bars. The temporary anchoring device comprises a plurality of groups or aplurality of detachable steel structures arranged between an upper bearing platform and a lower bearing platform which are connected through a swivel spherical hinge, and embedded parts respectively arranged in the upper bearing platform and the lower bearing platform. The temporary anchoring device is applied to a swivel cable-stayed bridge, and the implementation process of the damage-free quickmounting and dismounting temporary anchoring method comprises a mounting process, a monitoring process and a stable dismounting process. The device is simple in structure, convenient to mount and dismount and high in safety, the overall stability of a bridge can be guaranteed, an internal spherical hinge system is not affected, and swivel construction is safer and more reliable.

Description

technical field [0001] The invention relates to a temporary anchoring device and a temporary anchoring method, belonging to the technical field of swivel bridge construction. Background technique [0002] In the cantilever construction of continuous beams, the pier top box girder is theoretically poured symmetrically, but it is difficult to ensure that the weights on both sides of the box girder are consistent in the actual construction process, and the box girder will generate unbalanced moments, which will affect the internal spherical joint system , Laying hidden dangers for subsequent swivel construction. Therefore, temporary anchorage measures are arranged between the caps to eliminate the unbalanced moment generated by the box girder, so as to ensure the overall stability of the swivel T structure and reduce construction safety risks. [0003] In the symmetrical construction of the box girder on the top of the pier, relying solely on the spherical joint and the suppor...
