The invention relates to a concrete breaking and disease treatment method without damaging a hinge joint of a hollow slab beam. The method comprises the following four steps of concrete pre-cleaning, bottom blocking, deep layer repairing and surface layer repairing. The construction technology is simple, universality and environmental applicability are good, the requirement for rapid repairing operation of a bridge structure in various environments can be effectively met, the material use amount and the working difficulty in bridge repairing operation are effectively reduced, structural defects in the bridge structure can be effectively repaired, and the construction efficiency is improved. Therefore, the working efficiency and quality of bridge repair operation are greatly improved, and meanwhile, the labor intensity and cost of bridge repair and maintenance construction operation are effectively reduced. 本发明涉及一种不损害空心板梁铰缝混凝土破除及病害处治方法，包括如下步骤混凝土预清理，底部封堵，深层修复及表层修复等四个步骤。本发明施工工艺简单，通用性及环境适用性好，可有效满足多种环境下桥梁结构快速修复作业的
