Foundation pile reinforcing device with supporting force adjusting mechanism for road and bridge engineering

The utility model relates to the technical field of road and bridge engineering foundation piles, in particular to a foundation pile reinforcing device with a supporting force adjusting mechanism for road and bridge engineering. The raised lines are machined on the foundation pile, the springs are connected to the raised lines, and downward acting force is generated on the foundation pile through the raised lines by means of deformation of the springs, so that the foundation pile is reinforced; an adjusting mechanism is arranged, and a driving shaft drives a worm to rotate through a hand wheel, so that the worm drives a worm gear to drive a driven shaft to rotate; due to the fact that the bottom end of the moving block abuts against the horizontal section of the inverted-L-shaped plate, under the action of the threads, the moving block moves in the axial direction of the driven shaft, the pressure applying cylinder is driven by the push-pull rod to ascend and descend along the foundation pile, the deformation
