| description | The utility model discloses a road soft foundation construction device, and belongs to the civil engineering construction technology. Wherein the pile head is fixed at the lower end of the pile pipe and is of a conical structure with an upper opening; a plurality of discharging holes are formed in the side wall of the pile head in the circumferential direction, the pile pipe is connected with a limiting mechanism for opening and closing the discharging holes, the limiting mechanism comprises a limiting sleeve sliding up and down along the pile pipe and a sealing sleeve for sealing the discharging holes, and the inner wall of the sealing sleeve is attached to the outer wall of the pile head. The device is reasonable in structure; downward gravity is applied to the limiting sleeve by sand ofthe pile pipe; when the pile pipe moves downwards, the limiting sleeve moves downwards to open the discharging hole, then when the pile pipe moves downwards, the limiting sleeve descends under the action of upward thrust app |
