Concrete crack repairing structure

A concrete crack repairing structure comprises an inverted triangle glue injection groove, a seal-capping adhesive tape and an epoxy daub layer, wherein the inverted triangle glue injection groove is formed in a crack of a concrete layer; the apex angle of the inverted triangle glue injection groove is connected with the crack; the seal-capping adhesive tape is arranged above the inverted triangle glue injection groove and is pasted and fixed on the concrete layer on the two sides of the inverted triangle glue injection groove; the seal-capping adhesive tape is coated with the epoxy daub layer sealing the seal-capping adhesive tape on the concrete layer. The concrete crack repairing structure can effectively prevent crack blockage due to misoperation of daub during the crack sealing process so as to form a smooth glue saluting pouring passage, improve glue injection efficiency, and ensure repairing quality.
