description	The invention provides a mortar lining wall thickness design method and a pipeline repairing method and device. The mortar lining wall thickness design method comprises the steps that based on defect data of an existing pipeline, the pipe top vertical deformation amount when the existing pipeline reaches the designed use year after repair and the equivalent additional load needing to be applied when the existing pipeline reaches the pipe top vertical deformation amount are determined; and determining section and interface stress state parameters after the existing pipeline is repaired based on the equivalent additional load and the assumed value of the wall thickness of the mortar lining. And comparing the stress state parameter with the standard strength parameter, and judging whether the assumed wall thickness value of the mortar lining is used as the target wall thickness value of the mortar lining or not according to the comparison result. By means of the mortar lining wall thickness design method, the mo
