Description

TECHNICAL FIELD

[0001] The utility model belongs to bridge construction temporary anchoring technical field, provide a kind of quick dismounting temporary anchoring mechanism for bridge flat rotation system. BACKGROUND

[0002] In continuous beam cantilever construction, it is a key problem to ensure the overall stability of box girder. Due to the difficulty in maintaining the weight consistency of the two sides of the box girder in actual construction, it is easy to cause the generation of unbalanced moment, thereby affecting the internal spherical hinge system and increasing the risk in rotation construction. Therefore, it is necessary to adopt temporary anchoring measures to eliminate the unbalanced moment of the box girder.

[0003] The temporary anchoring measure is usually implemented in the form of pouring concrete outside the fine rolling threaded steel. Although this method is effective, due to the improper gap setting of the support feet between the pile caps during construction, different degrees of subsidence may occur in the two pile caps. This subsidence will cause the fine rolling threaded steel of the longitudinal anchoring to be compressed, and then yield phenomenon occurs, resulting in the failure of the temporary anchoring measure. Once the temporary anchoring fails, it will pose a serious threat to the construction safety and the overall stability of the bridge, and may cause huge economic losses.

[0004] In order to avoid this situation, special attention should be paid to the design and implementation of temporary anchoring measures during construction to ensure that they can effectively bear various loads generated during construction. At the same time, before the bridge is formally rotated, the convenience of removing the temporary anchoring measure should be considered, and after the completion of the bridge rotation, the temporary anchoring measure should be quickly implemented again.

[0005] In summary, the role of temporary anchoring measure in the construction of rotating bridge cannot be ignored, and it is an important guarantee for ensuring construction quality and safety. The construction team should pay full attention to it, and through reasonable design and meticulous construction management, ensure the effectiveness of the temporary anchoring measure, reduce the construction risk, and ensure the smooth progress of the project.
