In engineering construction, the construction of municipal roads and bridges has certain particularities. The support problem of bridges under construction is a relatively important issue at present. If the support strength of municipal bridges is not enough, it is easy to cause cracks or even collapse of the bridge surface due to too many vehicles on the bridge in the later operation. The invention patent with publication number CN116065495A discloses a high-strength support bracket for bridge construction. Through the design of the oblique support mechanism, when the adjustment of the lateral support steel body is completed, the oblique support is provided by the installation of the oblique rod, and the threaded adjustment rods at the bottom of the second vertical steel body and one side of the lateral support steel body are rotated respectively. The threaded adjustment rod drives the frame plate to move until the frame plate moves to fit closely with the slider. At this time, the slider is squeezed, and the interaction between the two sliders is restricted, so that the oblique rod can no longer swing. At this time, the oblique rod can provide a stable oblique support force for the lateral support steel body, ensuring that the other end of the lateral support steel body is supported; the ... The invention patent of 1855424A discloses a strength detection system and detection method for steel structure bridge prefabricated parts; the strength of bridge manufacturing prefabricated parts is detected by setting a detection device, and the bridge prefabricated parts are pre-extruded by an extrusion detection device to detect the pressure strength. The utility model patent with publication number CN210376000U discloses a strength detection device for highway bridge construction, which performs strength detection on the highway bridge to be detected by the detection device, and the highway bridge to be detected is subjected to all-round force by setting a bidirectional counterweight block, and then the pressure on the highway bridge to be detected is detected and recorded by the pressure sensor, and the detection data are analyzed later to measure the strength of the highway bridge.

Secondly, when detecting the strength, the impact strength and torsional strength of the supporting device cannot be detected simultaneously.
