Active waterproof system for anchorage foundation enclosure structure of suspension bridge and construction method

The invention belongs to the technical field of waterproofing and impermeability of deep foundation pits, and particularly relates to an active waterproof system of a suspension bridge anchorage foundation enclosure structure and a construction method.The active waterproof system of the suspension bridge anchorage foundation enclosure structure comprises a steel reinforcement cage and a cathode precipitation well, and at least one steel reinforcement on the steel reinforcement cage is replaced by a steel reinforcement anode of a coating layer; the steel reinforcement cage is a steel reinforcement cage in a cast-in-situ bored pile and/or an enclosure wall, a cathode steel bar section is arranged in the cathode dewatering well, and the coating steel bar anode and the cathode dewatering well are connected through a wire. According to the active waterproof system for the anchorage foundation enclosure structure of the suspension bridge and the construction method, a dry operation environment can be achieved befor
