The invention provides a full-packing waterproof station waterproof system and a method for dynamically setting limited drainage. The waterproof system comprises a surrounding rock grouting water stopping ring, a preliminary support, a drainage network system and a water-pressure-resistance lining structure, the drainage network system comprises longitudinal drainage pipes and transverse drainagepipes, and the longitudinal drainage pipes and transverse drainage pipes are provided with PVC capillary drainage plates. The system and method follow the principle that prevention is primary, rigidity and softness are combined, multi-channel protection is achieved, limited drainage is conducted, and comprehensive treatment is achieved. A traditional drainage method and a capillary water penetrating and drainage method are integrated, and the advantages of the two methods are combined; the advantage of a full-packing waterproof system that the influence on underground water and surrounding accessories is small is reserved, a limited drainage system is also designed to serve as the reservation for the full-packing waterproof system, the effect of avoiding accumulation of water and lifting of a water head is achieved, and the smoothness of a drainage pipeline is also guaranteed; the full-packing waterproof station waterproof system has the advantage of efficient drainage, and is suitablefor stations which have the low water outlet amount after excavation.
