The invention relates to a bridge crack detector with a constraint function and a detection method, and effectively solves the problem of poor effect caused by single means and function during bridge detection in the prior art. According to the technical scheme, steel cables are arranged along the two sides of a crack and are matched with a detection cylinder and an amplification cylinder, so that the overall development situation of the crack can be comprehensively obtained without excessive detection equipment, and when the crack is expanded to a certain degree, the crack can be accurately detected. Certain constraining force can be automatically applied to the crack (to limit too fast spreading of the crack), so that the effect of delaying the spreading speed of the crack as much as possible is achieved. 本发明涉及一种具有约束功能的桥梁裂缝检测器及检测方法，本发明有效解决了现有针对桥梁检测时手段、功能均较为单一而导致效果不佳的问题；解决的技术方案包括：本方案通过沿着裂缝两侧布置钢索并且与检测筒、放大筒之间的配合，从而实现无需过多的检测设备，即可较为全面的获得裂缝整体的发展态势，而且当裂缝扩展到一定程度时，可自动对裂缝施加一定的约束力(以限制裂缝的过快蔓延)，以实现尽量延缓裂缝的扩展速度的效果。
