[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are built across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient; with the increasingly developed transportation today, highways have been basically popularized, and highway bridges are conducive to the construction and continuity of highways. Highway bridges play a vital role in urban construction. When building a bridge, it is generally necessary to first test the bearing capacity of the bridge.

[0003] As urban bridge structures are bearing increasing weight, they are bearing greater vehicle loads, and it is necessary to test the bridge's bearing capacity to avoid bridge accidents. However, in actual testing, large cranes are usually used to lift workers to perform manual inspections with the naked eye.

The existing small-scale detection devices have relatively high overall operation difficulty and cannot be used to perform bridge bearing capacity testing in a more adaptable manner.
