description The invention provides a double-liquid grouting reinforcement method of a cement concrete plate. The method comprises the following steps that firstly, the void position of a cement concrete panel isdetermined through adopting a deflection detection method, the plate deflection is detected by using a deflection vehicle according to the current specification, and when the deflection is greater than 20 (0.01 mm), grouting reinforcement is performed; secondly, the arrangement of grouting holes is determined according to the condition of a pavement slab and grouting machinery, in order to ensurethat the overall strength of the panel is not damaged, five grouting holes are arranged in each plate, one plate corner grouting hole is arranged in each of the four plate corners, the center positionof the plate is provided with a plate center grouting hole, the plate center grouting hole can serve as a release hole, and the depth of the grouting hole should penetrate through the whole cement concrete plate; and thirdly,
