Description

Technical Field

[0001] The utility model belongs to the technical field of foundation compaction, and in particular relates to a highway foundation compaction device. Background Art

[0002] Compaction degree is one of the key indicators for roadbed and pavement construction quality inspection, which characterizes the density condition after on-site compaction. The higher the compaction degree, the greater the density and the better the overall performance of the material. For roadbed, pavement semi-rigid base and granular flexible base, compaction degree refers to the ratio of the dry density actually achieved on the construction site to the maximum dry density obtained by the indoor standard compaction test. A cart with a compaction roller is often used for compaction of highway foundation surfaces.

[0003] However, the width of the compaction rollers of the existing compaction carts is not easy to adjust, which results in the compaction rollers not being well adapted to wider and narrower foundation surfaces. For example, when the foundation surface is slightly wider than the compaction rollers, it will be necessary to subsequently re-compact the areas missed by the compaction rollers, which greatly consumes time and manpower. In addition, the compaction rollers are located in a position on the vehicle body that is not easy to adjust, resulting in poor adaptability to compaction applications in complex foundation conditions such as a central boss or a central trough.

[0004] Therefore, a highway foundation compacting device is needed to solve the problems in the prior art that the compacting roller has poor adaptability to wider and narrower foundation surfaces and poor adaptability to complex foundation conditions. Utility Model Content
