Compacting is an important process in the construction industry. Mainly serving to prepare the land for the incoming construction, it makes the land stable enough to have something built on it. There are a lot of advantages offered by having the ground compacted first. Compacting causes the soil's particles to be closer to each other, making it more resistant to different elements such as water and frost. In addition, it firms up the soil, making it more resistant to both contraction and expansion. Also, having a more stable building ground allows the soil to bear more weight. That said, it is a no-brainer that construction should always start with a compaction. But what are the different types of compaction equipment and when are they actually used? By definition, these tools, also called compactors, are designed to compact the land using different means. So what are the different characteristics of compactors? We should focus first on the most basic things about compactors. The compactor is a machine that forces soil molecules to bond to each other. By doing so, the land becomes denser and harder, allowing it to gain the properties mentioned in the last paragraph. It takes effort and energy to actually cause the compaction of the ground. And to do that, there must be force exerted. There are 2 general classifications of forces that can be used to compact the ground. The first one is static force. In this type of force, it is the weight of the machine pressing downward to the ground that causes the compaction of the soil. The next classification is the vibratory force. In addition to the weight of the machine, a vibrating force generated by the motor is used to create compressing force. During the vibrations, the compaction equipment sends waves of force to the lower layers of the soil. As these vibrations commence, the soil particles not only gets pressed, but also gets reoriented towards each other. What are the types of soil compactors? The most basic one is the roller. Using a huge wheel that can either be pneumatic or metallic, the sheer weight of the wheel is responsible for compacting the land. This is one example of a machine using static force. Another compactor that uses static force is the kneader. And then there are equipment utilizing vibrating force. A plane compactor is one popular form of this machine. Composed of a heavy steel plate on the bottom and a motor for rapid movement of the plate, such a machine is capable of sending massive amounts of force down to the deeper layers of the soil. A rammer is another example. A machine using the piston/spring system, it also repeatedly hits the ground below, causing it to compress because of sustained pressure. Each of these tools is used for specific conditions and soil types. Choosing the right compaction equipment for the job is arguably more effective and sensible than just using a powerful one. When looking for this equipment, make sure to check first your lot and the type of machine you're getting. Source: GOARTICLES
