Description
Technical Field
[0001] The utility model relates to the technical field of pipe piles, in particular to a spiral pile connection device for prestressed pipe piles. Background Art
[0002] Prestressed concrete pipe piles have been widely used in construction projects due to their advantages such as high single pile bearing capacity, high pile quality, and time saving. Prestressed concrete pipe piles are all factory-produced. For special projects, such as the foundation of power transmission line towers in mountainous areas, if a large-diameter single pile foundation is used, the length of the single-section pipe pile needs to be further reduced to facilitate the transportation and construction of the pipe piles in mountainous areas. In the construction process of prestressed concrete pipe piles, there is inevitably the problem of pile connection. During the pile connection process, it must be ensured that the coaxial deviation of the two piles is within the range allowed by the construction specifications. The existing pile connection method is to use a crane to lift the upper and lower sections of the pipe piles to align them, and finally perform the pile connection work. During the entire pile connection process, the pipe piles are more likely to shake, which requires manual repeated adjustment, affecting the efficiency of the pipe pile connection. Therefore, in order to correct the above defects, we propose a spiral pile connection device for prestressed pipe piles. Utility Model Content
