The specific operation flow is as follows:

in the natural sinking process of the bridge, the extending pile 5 and the bridge pile 24 descend together, so as to control the base 22 to move downwards, when a certain section of the base sinks, because of a height difference with the bridge deck 1 at two sides, at this time, the extending column 92 is pulled by the rope 96 to pull the moving frame 91 to move, the downward movement of the moving frame enables the transmission teeth 963 arranged on the moving frame to be clamped in the second convex teeth 962, so as to drive the outer ring 961 to rotate, the gear ring 69 can be driven by the outer ring in a one-way manner, so that the downward movement of the moving frame drives the gear ring to rotate, the third convex teeth 610 on the gear ring drive the sleeve column 64 provided with the first convex teeth 66 to rotate through the linkage of the first gear 611, so as to control the rotation of the transmission disc 65, the rotation of the transmission disc will drive the first fixing column 67 to extrude and rotate the first rotating rod 68 continuously, so as to extrude the extrusion block 614 continuously through the first rotating rod, so that the hydraulic oil in the extrusion transmission hydraulic chamber 613 continuously enters the lower part of the third chamber 45 by the back and forth movement of the extrusion block, thereby pushing the piston head 46 to move upwards to extrude the hydraulic oil above the third chamber, thereby pushing the hydraulic oil in the hydraulic oil cylinder to continuously enter the third chamber 45 through the first flow passage 47 by the back and forth movement of the piston block, and then the hydraulic oil inside enters the second chamber 43 from the third chamber along the second flow passage 48 by the extrusion of the piston block, thereby controlling the first support block 44 to move upwards to lift the bridge floor upwards, thereby compensating the height of the bridge floor so as to stably lift the height of the bridge floor, thereby ensuring the smoothness of the bridge floor, and at the moment, when the base sinks, the movement of the moving frame will drive the outer ring 961 to rotate, the rotation of the outer ring will drive the third gear 129 to rotate, the rotation of the third gear will drive the threaded rod 122 to rotate, the thread blocks 124 sleeved thereon are close to each other, and the moving plate 126 is driven by the second rotating rod 1210 to move outwards, thereby engaging with the third rack 128, and fixing the floating block 81 and the base to each other.

When the base is in a sinking state, when tide begins to rise, water generates buoyancy on the floating block, the base is driven to be lifted upwards through the buoyancy brought by the floating block, in the lifting process of the base, hydraulic oil in the second cavity enters the hydraulic oil tank through the third flow channel, at the moment, the first sliding block is driven to move upwards due to the fact that the moving frame moves upwards, the rack drives the second gear to rotate, the second gear rotates to drive the quantitative block 75 to rotate, the hydraulic oil in the second cavity is sent back to the third cavity according to the movement amount of the first sliding block 72, the first supporting block is controlled to descend stably, when the base is reset upwards, the outer column does not move and keeps the original position, the bridge pile moves upwards along with the base, water flow is filtered through the filter cloth 54 and then enters the first water inlet cavity 53 and then accumulates in the second water inlet cavity 54, promote chock plug 57, rivers will fill the position that the bridge pile was originally, and when the bridge floor atress of the top, the downward application of force of bridge pile, rivers will extrude the chock plug this moment, and the chock plug is in the closure state, so inside liquid will unable outflow, and the inside whole that then is a full water of filling of outward form this moment has played good fixed action, resumes the normal position until the base.
