What are the factors that affect the impact rolling times of the impact compactor?
Impact compactor is an efficient compaction equipment that is widely used in various engineering fields. Impact rolling is the main working mode of impact compactor, and its rolling times have an important impact on the quality and effect of the project. So, what are the factors that affect the impact rolling times of the impact compactor?This article will explain it for you.
1.Modulus of elasticity of soil.
The elastic modulus of soil refers to the ratio of stress to strain generated when the soil is subjected to a certain pressure within the elastic range. In the impact rolling process of the impact compactor, the lower the elastic modulus of the soil, the greater the impact force, and the less rolling passes are required. Conversely, the higher the elastic modulus of the soil, the more times of rolling is required.
2.Soil moisture content.
Soil moisture content is one of the important factors affecting the impact rolling times of impact compactor. In the case of low water content, the soil is relatively dry, the pores are relatively large, and it is not easy to be compressed. As a result, a high number of passes are required. In the case of high water content, the soil is more viscous, the pores are relatively small, and it is easy to be compressed. As a result, fewer passes are required.
3.Compaction thickness and compaction width.
The compaction thickness and compaction width of the impact compactor also have an impact on the number of impact rolling passes. When the compaction thickness is large, the impact force on the bottom of the soil is small, so it is necessary to increase the number of rolling passes to ensure the compaction effect. When the compaction width is larger, the impact compactor needs to span a larger working face and takes more time to complete the compaction work of the whole project, so it will also increase the number of rolling passes.
4.Travel speed and impact.
The travel speed and impact force of the impact compactor also have an impact on the impact rolling passes. The faster the driving speed, the greater the impact force, the better the compaction effect on the soil, and the less rolling passes are required. However, too fast driving speed may cause damage due to excessive impact force on the soil, so it is necessary to control the driving speed reasonably.
5.Mechanical model and power.
Different types and powers of impact compactors also have an impact on the number of impact passes. The high-power impact compactor provides greater impact and compaction force, thus reducing the number of passes required. Small-power impact compactors, on the other hand, require more passes to achieve the same compaction effect.
In summary, the impact rolling passes of the impact compactor are affected by a variety of factors, including soil elastic modulus, water content, compaction thickness and width, driving speed and impact force, mechanical model and power, etc. In the actual construction process, it is necessary to comprehensively consider these factors according to the specific situation, and reasonably determine the number of impact rolling times to ensure the quality and effect of the project.
