Abstract

The invention discloses a spiral bridge support, which comprises an upper support board (1) and a lower support board (6); a nut support (2) is arranged at the lower part of the upper support board (1), a lower support board cylindrical surface groove base (5) is arranged on the lower support board (6); and the upper support board (1) is connected with the lower support board cylindrical surface groove base (5) through a tripping preventing board (7). According to the invention, the manufacture and the assembly are convenient, the structure has a high reliability degree, and the maintenance property is very flexible; under normal operation, the support can satisfy deformation such as temperature deformation and concrete shrinkage and creep of the bridge; after the differential settlement of the bridge, the support can be lifted to satisfy the ride comfort standard of the bridge surface through simple operation; under the action of earthquake, the support can limit longitudinal and transversal earthquake displacement of the bridge, and prevent beam falling and beam tripping; and the support can effectively solve the problem of bridge falling and track unevenness which is caused by uneven settlement of the pier.

Description

technical field [0001] The invention relates to an anti-drop beam support, in particular to an upliftable support for anti-seismic anti-fall beam settlement repair for high-speed railway bridges. Background technique [0002] In recent years, with the rapid development of my country's economic construction, the construction of high-speed railway has developed more rapidly. However, for a high-speed railway with a speed of more than 200km / h, the vibration of the train caused by the irregularity of the track is far more serious than that of a normal speed train under the same conditions, that is, the comfort level of passengers will deteriorate due to the increase in speed. Therefore, the high-speed railway puts forward higher requirements for the smoothness of the track. However, due to the influence of natural disasters and subgrade geological conditions, the existing high-speed railway piers in service have different degrees of uneven settlement, which seriously affects th...
