Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal engineering technology, and in particular to a bearing capacity testing device for municipal highway bridges. Background Technology
[0002] To verify the quality of municipal highway bridges, their load-bearing capacity is tested. The principle of load-bearing capacity testing is to use a standard hammer of a certain mass to strike the piston at the top of the probe rod. The conical probe is then pressed into the soil through the drill rod. For each hammer blow, the impact velocity is measured by the sensor inside the piston, and the calculator in the electronic recorder calculates the penetration energy. At the same time, the depth of the conical probe is recorded. Using the traditional Dutch formula, the dynamic resistance value of the conical probe can be calculated immediately, thereby measuring the load-bearing capacity of the municipal highway bridge.
[0003] Traditional bridge load-bearing capacity testing methods often rely on manual operation or simple equipment, which is not only inefficient but also prone to inaccuracies and susceptible to human error, leading to significant deviations in the results. Furthermore, existing testing devices often lack stable installation structures, making them susceptible to tilting or displacement during use, further affecting test accuracy. Additionally, traditional testing methods are mostly single-point measurements, failing to comprehensively reflect the overall load-bearing capacity of specific bridge areas, and are labor-intensive and inefficient, hindering large-scale application. Therefore, we propose a load-bearing capacity testing device for municipal highway bridges. Utility Model Content

[0030] A municipal highway bridge bearing capacity testing device includes a mounting plate 1. The upper end of the mounting plate 1 has four first connecting holes 11. The four first connecting holes 11 are used to fix a hammering component 6. The lower end of the mounting plate 1 is fixedly connected to six support columns 2. The six support columns 2 are used to detachably install a support component 5. The outer surfaces of two opposing support columns 2 are used to fix a connecting rod 3. The upper end of the connecting rod 3 is slidably connected to three probes 4. The six support columns 2 are distributed in a ring with equal angular dimensions, and the three probes 4 are distributed in a transversely equidistant dimension.
[0031] In this embodiment, the support component 5 includes a fixing plate 51 and a stop bar 57. Six mounting sleeves 52 are fixedly connected to the upper end of the fixing plate 51, and four fixing rods 53 are fixedly connected to the lower end of the fixing plate 51.

A ground nail 56 can be detachably installed in each of the four first mounting holes 55. Four second mounting holes 58 are opened through the upper end of the stop bar 57. The diameter of the ground nail 56 is equal to the inner diameter of the first mounting hole 55 and the inner diameter of the second mounting hole 58. The four connecting plates 54 are distributed in a ring with equal angular dimensions. The positions and dimensions of the six mounting sleeves 52 and the six support columns 2 are corresponding and adapted to each other. The diameter of the fixing plate 51 is larger than the diameter of the mounting plate 1.
[0032] The above solution aims to improve the stability of equipment installation and prevent tilting during testing.

To improve the stability of the device installation and prevent tilting during testing, the positions of the six support columns 2 and the six mounting sleeves 52 are aligned, so that they can be detachably installed on the upper end of the fixing plate 51. The connecting plate 54 is placed on the bridge ground, and four ground nails 56 are driven in. The second mounting holes 58 are fitted onto the outer surface of the four ground nails 56, so that the stop bar 57 simultaneously fixes the ground nails 56, improving the subsequent testing accuracy.
