The base part comprises a central base(10a), an inner inclined base(10b), and an outer inclined base(10c). The inner and outer walls are vertically separated from the central base. The inner and outer partition walls are vertically formed between the inner and outer inclined bases and the inner and outer walls. The sheet pipe is downward extended from the bottom surface of the central base and is inserted into the inner core of a dam(20).
