Bridge deck crack high-strength repairing method
The invention discloses a high-strength bridge deck crack repairing method, which belongs to the technical field of bridge deck construction. The method comprises the following steps: reasonably expanding a crack, uniformly punching holes in the side wall of the crack, injecting magnetic concrete, bridging two adjacent holes in a self-connecting piece put into the crack on the basis of a magneticattraction effect, triggering self-anchoring ball on the self-connecting piece to make a gap, a chemical reaction being controlled to be generated and stopped, then the propelling effect of gas beingcontrolled. High-frequency impact is formed in a hole through the punching column to achieve punching, finally, after punching is finished, the bonding action is triggered, and the punching column isforced to be in multi-point deep connection with the hole wall permanently. Then repairing concrete is injected into the cracks, on one hand, the repairing concrete enters the self-connecting piece tobe reinforced and shaped, on the other hand, the cracks are filled, the connecting effect on the bridge floor on the two sides of the cracks is formed after forming, a tensile force is given all thetime, the secondary cracking phenomenon is avoided, and the repairing strength is greatly improved.
本发明公开了一种桥面裂缝高强度修复方法，属于桥面施工技术领域，本发明可以通过先对裂缝进行合理扩缝，然后在裂缝侧壁上均匀打孔，并注入磁性混凝土，基于磁吸作用将投入裂缝的自连接件进行相邻两个孔之间的桥接，并触发自连接件上自锚球的造隙动作，通过控制化学反应的发生和停止，进而控制气体的推进的作用，通过凿孔柱在孔内形成高频冲击实现凿孔，最后在开凿结束后触发粘接动作，迫使凿孔柱永久性与孔壁形成多点深入连接，接着向裂缝内注入修复混凝土，一方面进入到自连接件内进行补强和定形，另一方面对裂缝进行填充，在成型后形成对裂缝两侧桥面的连接作用，并始终给予一个拉力避免二次开裂的现象发生，大幅提高修复强度。
