The currently used beam bridge support comprises a lead-core shock-insulation rubber support, a lead-free shock-insulation rubber support, a horizontal force dispersion support, a highway bridge basin-type support, a basin-type support, and other supports, wherein the supports are installed on gradient prefabricated beams in the longitudinal bridge direction, the transverse bridge direction or the longitudinal and transverse bridge direction, and generally, leveling steel plates are pre-buried (or welded) on the bottom surface of a beam body, and then the supports are installed. The traditional installation mode has the following defects: the backing plate heightening support takes out the upper support plate anchoring bolt through heightening the height of the lower support basin plug, the manufacturing cost of the support is high, the quality cannot be guaranteed, the precast beam body and the design gradient are inconsistent or part of the support is empty after the beam body is in place, the support is finally damaged unevenly and prematurely due to stress, and small difficulty and trouble are brought to the safety and maintenance of the bridge.
In the bridge construction process, the bridge body elevation is inevitably regulated by adopting a heightening support through a subsided geological region, and the existing heightening support comprises a backing plate heightening, filling heightening, spiral heightening and the like. The base plate heightening support meets the requirement of heightening operation space, and a certain building height is increased compared with a common support, so that the weight of the support is increased, and the cost is increased. The filling height-adjusting support is difficult to construct in practice, the filler is easy to leak after being pressed for a long time, and the height-adjusting effect is not easy to achieve. The spiral heightening support has the advantages of high processing difficulty, high manufacturing cost, high heightening construction difficulty and less application.
