High-waterproof roofing structure for accumulated water seepage prevention of building

The invention discloses a high-waterproof roofing structure for accumulated water seepage prevention of a building. The high-waterproof roofing structure comprises a roof, a water tank is laid and fixed to the upper surface of the roof, a waterproof plate is fixed to the top of the water tank through brackets, collecting gutters are formed in the two sides, in the length direction, of the waterproof plate, guiding pipes are connected between the collecting gutters and the water tank, and filter covers are arranged at the tops of the guiding pipes. According to the high-waterproof roofing structure for accumulated water seepage prevention of the building, in the using process, rainwater can flow into the collecting gutters through guide grooves on the waterproof plate, and then flow into the water tank to be stored through the guiding pipes, when the amount of therainwater is too much, the water tank has no time to store or is full, the rainwater can be discharged into a sewer through adrain pipe, through stru
