Description

Technical Field

[0001] The utility model relates to the technical field of compaction equipment, in particular to a cement-stabilized crushed stone base compaction equipment. Background Art

[0002] Working principle of cement stabilized gravel: cement stabilized gravel uses graded gravel as aggregate, uses a certain amount of cementitious materials and sufficient mortar volume to fill the gaps in the aggregate, and is spread and compacted according to the principle of interlocking. Its compaction is close to its density, and its strength mainly depends on the interlocking principle between the gravel, and there is sufficient mortar volume to fill the gaps in the aggregate. It has high initial strength, and its strength increases with age and quickly forms a board, so it has high strength, good impermeability and frost resistance. The cement content of cement stabilized gravel is generally 3% to 6% of the mixture, and the unconfined compressive strength after 7 days can reach 5.0Mpa, which is higher than other roadbed materials. After cement stabilized gravel is alive, it will not be muddy in rain, and the surface is solid, which is an ideal base material for high-grade pavement.

[0003] After the cement-stabilized gravel base is laid, it needs to be compacted using compaction equipment. Considering the size of the site, when the construction site is small, it is not convenient for large compaction equipment to enter the site. Currently, a small manual compaction equipment has appeared on the market, which mainly meets the needs of small construction sites. Since the small manual compaction equipment is mainly pushed manually, it increases the fatigue of the workers and also affects the compaction efficiency of the cement-stabilized gravel base.

[0004] Therefore, a cement stabilized gravel base compaction device is proposed. Utility Model Content

At this time, the fixation of the compacting wheel can be released, and then the compacting wheel can be directly disassembled from the inside of the U-shaped part. Compared with the existing ones, the utility model is convenient for disassembly and maintenance of the compacting wheel, which helps to improve the working efficiency of the compacting wheel.
