Problems solved by technology
[0002] In the process of bridge construction, it is inevitable to pass through subsidence geological areas. In order to ensure the normal use of the bridge, it is necessary to use height-adjusting supports to adjust the height of the beam body. Height and spiral height adjustment, etc., while the traditional filling height adjustment support needs to use external tools to lift the beam body first, then adjust the height of the support, and then lower the beam body to the upper part of the support, which may easily cause the support to fall during the operation. The adjustment accuracy error is large, and there is also the risk of falling beams, and after the beam body is put back on the support, once the beam body is not stable, the height adjustment support cannot be adjusted again under the condition of load

The invention relates to the technical field of bridge supports, in particular to an ultrahigh-pressure height adjusting and pressure measuring support. An annular copper ring is arranged at the upperportion of a longitudinal injection hole, the annular copper ring is ejected up first when a filler is injected, then the annular copper ring acts on the upper portion of a rubber seal ring, and therefore the problem that the rubber seal ring partly bears high pressure and is extremely prone to a breakage failure is avoided; and the longitudinal injection hole is in a hopper shape, through the hopper-shaped structure, the lower pressure of the longitudinal injection hole is higher than the upper pressure when the filler enters the longitudinal injection hole, and the problem that the injectedfiller is prone to flowing back is effectively avoided.
