The invention relates to a self-repairing anti-root-penetrating concrete waterproof structure and a construction method thereof. The self-repairing anti-root-penetrating concrete waterproof structure is characterized by comprising a self-repairing rigid waterproof layer and a root barrier layer. The root barrier layer is formed by coating a root repellent layer on the self-repairing rigid waterproof layer. The self-repairing rigid waterproof layer comprises, by weight, 1 part of cement, 1.2-1.8 parts of sand, 3-4 parts of fine aggregate, 0.37-0.48 part of water and 0.008-0.015 part of cement-based capillary crystalline waterproofing agent. The root barrier layer has a function of root penetrating prevention and is formed by coating 0.3-0.8 kg/m the root repellent layer on the self-repairing rigid waterproof layer. Under synergistic effect of the self-repairing rigid waterproof layer and the root barrier layer, the self-repairing anti-root-penetrating concrete waterproof structure is capable of effectively pre
