Background
The bridge support is an important structural component for connecting an upper structure and a lower structure of a bridge, and can reliably transmit the counter force and the deformation (displacement and corner) of the upper structure of the bridge to the lower structure of the bridge. The spherical support has large bearing capacity, large displacement, flexible corner, consistent rotation performance in all directions and wide temperature application range; therefore, the spherical support is widely applied to various highway municipal railway bridges.
However, the traditional spherical support has no force measuring function, the stress condition of the support cannot be detected and the vertical bearing capacity of the support cannot be read in the using process, the internal force distribution condition of each section of the structure cannot be accurately known, the reliability of the bridge design theory and the rationality of the design method cannot be verified, and great inconvenience is brought to the maintenance and the structure monitoring of the support. When the spherical support is abnormal in the operation process, the stress condition of the support cannot be visually detected, so that the operation state of the upper structure of the bridge cannot be judged, and the health condition of the bridge structure cannot be monitored and evaluated in time. In addition, when the pier foundation on the soft soil foundation is unevenly settled, various prefabricated beams and continuous structures are slightly deformed after being tensioned, the bearing pressure of the bridge support is uneven and even the phenomenon of three legs occurs due to factors such as construction errors and the like which are difficult to avoid by the elevation of the supporting padstone of the beam structure, the stress state of the upper and lower structures of the bridge can be changed, and the potential safety hazard is brought to the structure. In addition, the traditional spherical support does not have the function of stepless height adjustment, and the height difference of a bridge generated during construction height error and use cannot be subjected to stepless height adjustment, so that the stress of each support is adjusted.
Therefore, the stress condition of the bridge support can be known in time, and the height can be adjusted in time when the support is unloaded and detached so as to avoid three-point support when a vehicle passes a bridge, which is an economic and effective solution for avoiding catastrophic accidents of the bridge, and the internal sensor of the existing force-measuring support is not easy to replace.

The principle of the invention is as follows: firstly, a support is arranged between a beam body and a pier, by utilizing the characteristics that when a force-measuring elastic body 4 bears pressure in a cavity, the pressure is uniform at each part in the cavity, the positive pressure is basically the same as the pressure of the force-measuring elastic body 4 to the base side, the end of a sensor 10 arranged on the outer side surface of the force-measuring elastic body 4 senses the pressure stress change of the force-measuring elastic body 4 and outputs a pressure wavelength signal to a demodulator, the demodulator analyzes and processes the wavelength signal and transmits the wavelength signal to a computer for processing through a wireless network or a wired network, then the actual load of the support is visually displayed and compared with the normal use load of the support, when abnormal occurs, an alarm is given to realize the remote monitoring of the load of the support, then the height of the support bearing with abnormal stress is adjusted, the beam body is jacked for a certain distance, the anchor bolt of the support is unscrewed, make the atress of each support even, then screw up the anchor bolt, accomplish support altitude mixture control, if need change sensor 10, directly open shrouding 13, operating personnel singlehanded stretches into from changing hole 15, will treat the sensor 10 of changing and take out, installs new sensor 10, with shrouding 13 reconversion, sensor 10 changes convenient and fast high-efficient.
The foregoing is only a preferred embodiment of the present invention, and the present invention is not limited thereto in any way, and any simple modification, equivalent replacement and improvement made to the above embodiment within the spirit and principle of the present invention still fall within the protection scope of the present invention.
