Description
Technical Field
The utility model relates to a bridge equipment technical field, especially a hollow rubber plate structure for heightening type basin formula rubber support.
Background
With the progress of the capital construction technology in China, more and more special bridges are provided. For example, a wide bridge has more beam supports, belongs to a hyperstatic structure, and can not be uniformly stressed in the vertical direction due to manufacturing, construction errors and the like. After the bridge is formed, the actual stress of the local support is smaller than the design requirement. At this time, if the height of the pedestal is raised, the design requirement can be met.
In addition, because the breadth of the country is wide, the geological structure is more complex. And some bridges must be built on these complex geological structures. These complex geology may be hard rock or soft gravel or quicksand. A soft gravel or quicksand foundation, while subjected to the necessary strengthening treatment, is not always feasible. In actual use, foundation settlement and displacement cause pier deflection, and cause the bridge to be unable normal use even collapse. In this case, if the height of the pedestal can be raised, accidents can be prevented.
Conventional bridge supports do not have the function of height adjustment. The general practice is to use a jack to jack up the bridge and install a steel backing plate on the upper part or the lower part of the support. This practice has certain limitations because of the need to arrange jacks, which have requirements on jacking position or space, and many bridges do not have much space and are therefore difficult to deploy.
