The invention discloses a construction method for a vibrating sunken tube construction secant pile wall, and belongs to the technical field of construction. The construction method comprises the construction steps: construction preparation, pile position measuring and unreeling, construction of a guide wall, vibrating and sinking casing pipes in position by using a vibrating sunken tube pile machine, construction of a first plain concrete pile, earth taking through an in-position rotary drilling rig, concrete pouring and casing pipe removing, construction of a second plain concrete pile, construction of a third plain concrete pile, construction of a first steel reinforcement cage concrete pile, construction of a second steel reinforcement cage concrete pile and the like. The steps are repeated in sequence until the completion of the secant pile walls. The construction method is fast in construction speed, the construction time of a single pile is about six hours, construction efficiency is improved, the casing pipes are pressed down and pulled off by using a vibration mode, a vibration function is performed on concrete poured underwater, the situation that the steel reinforcement cage floats upward is effectively controlled, the concrete is denser and solider, the quality of a pile body is higher, and the method is suitable for bracing engineering of foundation pits in suburbs, and is particularly suitable for the construction of the secant pile wall of the soil layer of silt, clay and sludge.
