This invention discloses a device and construction method for solving the problem of collapsed boreholes in loose sand layers, relating to the field of building construction technology. It includes multiple gravity blocks assembled to form a truncated cone, a lifting rod for controlling the downward movement of the gravity blocks within the pile hole to the collapsed area, and a compression head for downward expansion of the gravity blocks. The inner surface of the gravity blocks is inclined from top to bottom, and the compression head is truncated cone-shaped and can be inserted into the truncated cone formed by the gravity blocks.
