Description

Technical Field

[0001] The utility model relates to the technical field of highway detection, in particular to a embankment parameter experimental detection platform. Background Art

[0002] An embankment is a fill roadbed that is higher than the original ground. It is a structure with a certain density and strength formed by filling soil or stone. Its main function is to support the roadbed and pavement, and to bear the load of the pavement and vehicles, ensuring the stability and strength of the road. For different pavements, the structural selection of the embankment is very important. It is an important means to maintain road stability and ensure the service life of the road.

[0003] The bearing capacity and stability of embankment fillers are important design indicators in embankment projects. Currently, the main research directions are soil compression deformation and self-weight of the roadbed. Currently, the testing of material properties is carried out by preparing individual samples for different materials and testing each parameter. The parameters are then superimposed and calculated to obtain the overall parameters of the embankment. This method is time-consuming, requires multiple research groups to conduct experiments, and results in large overall errors. Therefore, we propose an embankment parameter experimental testing platform to address the above issues. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to enable people skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0028] See also Figure 1-6, a road embankment parameter experimental detection platform, which is used for measuring parameters after compaction and superposition between different materials on the embankment. Specifically, it includes a base 1, a support frame 3 installed on the base 1, a console 7 installed on the support frame 3, and a hydraulic cylinder 8 installed on the console 7. The hydraulic part of this application is a traditional hydraulic press in the laboratory. This application is improved from the existing hydraulic platform. A connecting block 6 is installed at the end of the hydraulic cylinder 8. The connecting block 6 is detachably connected to the end of the hydraulic cylinder 8. A mounting platform 5 is detachably installed on the connecting block 6. A pressing block 4 is rotatably installed on the mounting platform 5. The mounting platform 5 and the pressing block 4 are both cylindrical and cooperate with the filling pipe 24 to perform compaction work. A driving structure for driving the pressing block 4 to rotate is installed on the mounting platform 5. When in use, the pressing block 4 can rotate to improve the uniformity of compaction. The pressure can be adjusted by the hydraulic cylinder 8. Furthermore, a plurality of pressing rollers 23 are distributed at the bottom of the pressing block 4, which crushes the raw material by the pressing rollers 23. The compaction uniformity is good, which can better simulate the compaction work of real road conditions and the data is more in line with reality.

[0029] The base 1 is equipped with a supporting plate 12 through a support rod 14. When in use, the supporting plate 12 is located in the filling tube 24 and can support the filling tube 24. Since the filling tube 24 is open at both ends, the bottom of the filling tube 24 can also be sealed to ensure normal filling and compaction of the material.

[0030] In the present invention, the mounting platform 5 and the pressing block 4 are rotatably connected via a second rotating shaft. When the pressing block 4 is able to rotate, a certain distance is left between the mounting platform 5 and the pressing block 4 .

[0031] In the present invention, a mounting groove 21 corresponding to the connecting block 6 is provided on the mounting platform 5. During installation, the connecting block 6 is installed into the mounting groove 21. A threaded hole 22 is provided on one side of the mounting groove 21, and a positioning groove 20 corresponding to the threaded hole 22 is provided on one side of the connecting block 6. Screws are provided in both the threaded hole 22 and the positioning groove 20. After the mounting platform 5 is installed, the screws are used to limit the position, so that the mounting platform 5 can be stably supported and the pressure is provided stably.

[0032] The worm gear 16 is connected to the worm gear 16 by the gear 18 and the worm gear 16 is connected to the worm gear 16 by the gear 18. The worm gear 16 is connected to the worm gear 16 by the gear 18. The worm gear 16 is connected to the worm gear 16 by the gear 18. The worm gear 16 is connected to the worm gear 16 by the gear 18. The worm gear 16 is connected to the worm gear 16 by the gear 18.

[0033] In the present invention, since the rotation of the pressure block 4 will generate a certain torque on the hydraulic cylinder 8, a guide rod 9 is also installed on the connecting block 6. One end of the guide rod 9 passes through the console 7 and is slidably connected. The torque of the pressure block 4 is offset by the guide rod 9 to ensure the normal use of the hydraulic cylinder 8.

[0034] In some embodiments, a support platform 2 is also installed on the base 1, and the support rod 14 passes through the support platform 2 to support the support rod 14. During the experiment, the filling tube 24 contacts the support platform 2. When installing the support platform 2, the problem of unevenness of the base 1 can be overcome by adjusting the size.

[0035] In some embodiments, the filling tube 24 needs to be knocked to distribute the material inside it as horizontally as possible. Therefore, a groove is provided at the bottom of the base 1, and a spring 13 is installed in the groove. The support rod 14 is fixed on the spring 13. During the knocking process, a large vibration can be generated to help spread the material.

[0036] In some embodiments, in order to better support the filling tube 24, a bracket 10 is installed on one side of the support frame 3. A support groove 11 is provided in the bracket 10. After installation, the filling tube 24 contacts the support groove 11 to support it.

[0037] It can be seen from the above technical solution that when the present application is in use, the filling tube 24 is placed vertically on the base 1, wherein the supporting plate 12 is located in the filling tube 24. According to the operating standards, different samples are poured into the filling tube 24, and after knocking the filling tube 24 to make the internal material roughly flat, the pressing block 4 is controlled to roll the material at a set pressure. During the rolling process, the pressing block 4 rotates and is compacted by the pressing roller 23, and then the pressing block 4 is lifted, and the thickness of the unit material after being compressed is measured. Then, the raw materials for the embankment operation are added in turn, and the material quantity and the thickness of the unit mass of the material in the unit plane are recorded. After all the raw materials of the embankment are added, the height and mass of the overall material are calculated, and the actual thickness value and mass of the individual materials after superposition can be obtained, and the influence of the embankment's own weight, the actual deformation of the material and the selection of raw materials can be indirectly obtained.
