[0002] Bridges make a great contribution to transportation in the course of life. However, as time goes by, the base of the bridge is hit by the impact of water flow. The bottom support structure changes, and at this time, the base of the bridge is prone to drop. , the sinking of the bridge will be reduced by the horizontal distance of the corresponding bridge deck, resulting in a height difference, which will cut off the normal service life of the bridge. car phenomenon, resulting in car damage and personnel safety issues

Embodiment Construction
[0039] Such as Figure 1-24 As shown, a high-life anti-sinking bridge includes a bridge deck 1, a bridge pier 2, and a support 3; the bridge pier 2 is located below the bridge deck, and the support 3 is used to connect the bottom of the bridge deck and the bridge pier; the bridge pier 2 includes Pillar 21, base 22, connecting beam 23, bridge pile 24, connecting piece 25, extension block 26, first cavity 27, lifting structure 4, extension pile 5; Below the pillar, the connecting beam 23 is arranged on the base, the bridge pile 24 is arranged under the base to fix the base, the connecting piece 25 is used to connect two adjacent bridge decks, and the extension block 26 is arranged around the base. Around the base, the first cavity 27 is set in the extension block, the lifting structure 4 is used to compensate the sinking of the base, and the extension pile 5 is sleeved outside the bridge pile to have an extension function.
[0040] Such as Figure 5-6 As shown, the lifting str...

The invention discloses a long-service-life anti-sinking bridge which comprises bridge decks, bridge piers arranged below the bridge decks and supports used for connecting the bottoms of the bridge decks with the bridge piers. The bridge piers comprise supporting columns used for supporting the bridge decks, bases arranged below the supporting columns, connecting beams arranged on the bases, bridge piles arranged below the bases and used for fixing the bases, connecting pieces used for connecting every two adjacent bridge decks, extending blocks arranged on the peripheries of the bases in a surrounding mode, first cavities formed in the extending blocks, lifting structures used for compensating the sinking of the bases, and extending piles which are arranged outside the bridge piles in a sleeving manner and have the extending function; through the arrangement of the lifting structures, the height of the bridge bases can be compensated in the natural sedimentation process of the bridgebases, so that the heights of the bridge decks are kept constant all the time, the driving safety problem caused by bridge deck sedimentation is effectively avoided, the vehicle jumping problem is reduced, and traffic accidents are reduced.
Description
technical field [0001] The invention belongs to the technical field of bridge design, in particular to a long-life anti-sinking bridge. Background technique [0002] Bridges make a great contribution to transportation in the course of life. However, as time goes by, the base of the bridge is hit by the impact of water flow. The bottom support structure changes, and at this time, the base of the bridge is prone to drop. , the sinking of the bridge will be reduced by the horizontal distance of the corresponding bridge deck, resulting in a height difference, which will cut off the normal service life of the bridge. The phenomenon of the car, resulting in damage to the car and the safety of personnel. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a long-life anti-sinking bridge with self-recovery capability and high safety. [0004] In order to achieve the above object, the present invention adopts t...
