Description

Technical Field

[0001] The utility model belongs to the technical field of roadbed construction, in particular to a multifunctional trolley for processing the new and old joint parts of the roadbed improvement layer of a highway reconstruction and expansion project. Background Art

[0002] With the development of national infrastructure, there are more and more highway reconstruction and expansion projects. As the transition layer between the earth roadbed and the road surface, it is of great significance to control the construction quality of the improvement layer. After the water-stabilized material at the bottom of the old road concrete surface layer is milled, due to the limited mechanical construction space, the grader cannot scrape and level the remaining material during the movement process. The remaining material accumulates at the junction of the new and old roadbeds, and then it is leveled and cleaned manually, and compacted with a handheld flat rammer.

[0003] The junction between the old and new parts of the roadbed improvement layer was manually leveled, cleaned, and compacted with a handheld flat rammer, which had the following problems:

[0004] 1. The space at the junction of the new and old roadbeds is relatively small, and the scraper of the grader cannot extend into the lower part of the old road concrete surface layer to level the excess filler. Manual cleaning and leveling are adopted, and the excess filler is manually cleaned with a bucket truck, which is inefficient;

[0005] 2. Manual compaction using small machines or flat plate compactors has a small striking area, small exciting force, poor compaction effect, and slow compaction speed, which cannot meet production needs;

[0006] 3. The new and old junctions of the roadbed improvement layer are generally leveled and cleaned manually, and compacted with a handheld flat plate rammer, which requires a large number of workers, has high labor intensity, and the construction speed does not match the mechanized roadbed construction, which is likely to have an adverse impact on the construction period;

[0007] 4. The junction of the new and old roadbeds is a weak link in the reconstruction and expansion of expressways. Manual compaction and other operations are quite random, which can easily cause problems such as vibration leakage, insufficient vibration time, and insufficient compaction, leaving hidden dangers for the project;

[0008] 1. There is intensive manual construction adjacent to the new and old roadbeds being rebuilt and expanded, and high-speed vehicles are running on one side, which often causes accidents of knocking down temporary isolation, posing a high risk of construction safety;
