The invention relates to a pile foundation construction platform. The pile foundation construction platform comprises a platform body. A pre-fixing device is arranged on the upper portion of the platform body. The pre-fixing device comprises a closed ring. Squeezing plates distributed on the two sides are arranged in the closed ring. The face-to-face sides of the squeezing plates are provided withbevels facilitating reinforcement cages to slip off to the bottom of the closed ring. A plurality of buffer blocks are arranged on each bevel. The bottom of the pre-fixing device is provided with a limiting device used for limiting the reinforcement cages to pass through the pre-fixing device. A squeezing device used for fixing the adjacent reinforcement cages is further arranged on the middle portion of the pre-fixing device. The pile foundation construction platform has the advantage of facilitating connecting of the reinforcement cages and feeding the reinforcement cages into pile holes.
