The invention discloses a vibrating compaction test device, which comprises a track, a template box, a rack and a main driving device and a vibrating wheel connected onto the rack, wherein the track is arranged outside a pair of side walls of the template box; the vibrating wheel is connected at the lower part of the rack and located inside the template box; and through the main driving device, the vibrating wheel is controlled to rotate and vibrate to drive the rack to perform reciprocating motion along the track, thereby realizing vibrating compaction of a test accessory inside the template box. The test can be completed indoors and is not influenced by the weather. When the compaction test is carried out on other materials, the vibrating wheel only needs to be raised and replacement of the material can be completed; when the vibrating compaction test is carried out on a roller of different tonnage, different rack clump weights only need to be increased or decreased; when the vibrating compaction test is carried out on a roller of a different amplitude specification, different wheel body clump weights only need to be increased or decreased; and multiple working conditions can be simulated, the test cost is reduced, and the test efficiency is improved.
Description
technical field [0001] The invention relates to a road roller performance test device, in particular to a vibration compaction test device. Background technique [0002] In the process of engineering construction, according to the compaction material, the water content of the material, and the compaction thickness, the road rollers for rolling the pavement are required to have different vibration intensities, and the road rollers are required to have different working qualities, that is, it is necessary to ensure the amplitude , frequency and other parameters meet the requirements of construction operations. At the same time, with the application of new materials and new processes in engineering construction, new construction process specifications are also being continuously improved and developed. In this process, it is necessary to obtain data through different tests to guide the main production, ensure the quality of the project and improve the construction efficiency. ...
