What are the classifications of compaction machinery? Introduction to static rolling compaction machinery
Compaction machinery uses mechanical force to Earthmoving machinery with dense filling layers of soil, gravel, etc. Widely used in foundations, roads, airports, dams and other projects. So what types of compaction machinery are there??The following is the common types of compaction machinery compiled by the editor and their detailed introduction.
Compaction Machinery Classification
1. Static rolling compaction machinery: It uses the gravity of the roller, to cause permanent deformation and density of the pressed layer. The grinding wheels are divided into: smooth grinding, groove grinding, sheep’s foot grinding and tire grinding, etc. The surface compacted by light rollers is flat and smooth, and they are the most widely used;Trough rollers and sheep’s foot rollers have larger unit pressures, Thickness of compaction layer, is suitable for compaction of roadbeds and dams. The tire roller has a kneading effect during the compaction process, making the compaction layer even and dense without damaging the road surface. It is suitable for compacting cushion layers such as roads and squares.
2. Impact compaction machinery: relies on mechanical impact to compact soil. There are fire rammers that work on the principle of a two-stroke internal combustion engine, frog rammers that work on the centrifugal force principle, and quick impact rammers that work on the linkage mechanism and springs. Its characteristic is that the compaction thickness is large, and it is suitable for compaction of small areas and foundation pits.
3. Vibratory compaction machinery: Use mechanical excitation force to rearrange and compact material particles in resonance, such as plate vibratory compactors. It is characterized by high vibration frequency and good compaction effect on loose soil and rocks with low cohesion, such as sand and gravel.
4. Compound action compaction machinery: vibratory rollers with rolling and vibration effects, impact rollers with rolling and impact effects, etc.
5. Vibratory roller with vibration effect: It is formed by installing an exciter on the roller. It is a rapidly developing model and has replaced the static roller. Compactor Trends.
