DZJ-400Tandem Vibratory Hammer Used in Ma'an shan Bridge
Yongan DZJ-400 tandem vibratory hammer is successfully used in Maanshan Yangtze River Bridge MQ-3 section. This section includes North Tower and Approach Bridge over the river bank. The north tower foundation uses 54 bore-hole poured piles 2.5meters long. These piles are 76meters long and their bottom elevation is 75 meters high underwater. The pile bottom load-bearing stratum is slightly weathering sandstone layer. The pile cap is bending rectangle, the plan dimensation is 69.6M*32.1M, the thickness is 6M. The tower is gantry structure which is assembled by the tower column (bottom, middle, top), the beam (upper and down) and the tower top. The tower column is steel concrete structure, the lower beam is prestressing force concrete structure, and the upper beam is steel structure. The tower height is 175.8m (Counting from the bottom of the tower).
