STUDY OF EQUIPMENT FOR CONDUCTING SOIL COMPACTIONS FOR SMALL CONSTRUCTION OBJECTS

Abstract

Compaction of soils of different composition is widely used in all types of construction. To carry out these works, the domestic industry produces various types of machinery and equipment. The range of these tools is constantly expanding. Their capacity is also growing and their working bodies are improving. Under these conditions, the issue of increasing productivity, and quality of work is very important, which is possible only with the right choice of general structural schemes of machines and their parameters. One of the important parameters of the compaction process is the time factor or the ability to change the effect of vibration on the treated medium. Increasing the time of exposure of the working equipment to the material to be compacted, or the intensity of the action improves the conditions of formation of the structure of the rolling layer, and its greatest strength is achieved. When performing work on private plots of small area, compact road equipment, such as a mini-roller, has found wide application in the process of soil compaction, which involves work in a limited space. This paper proposes the design of such a technique, which is equipped with a mechanism for smooth change of force that excites vibration. To perform soil compaction operations for small objects, we have proposed to use an advanced manual vibrating roller with a step change of static torque and autonomous power supply from the battery, which is connected to the drive through the inventory. The change of static moment occurs due to the change of the angle of inclination from the centre of unbalance to the axis of rotation of the shaft. If it is necessary to arrange the foundations for laying various road and decorative coatings in individual construction, a vibrating roller is used, which not only has a compact design, but also does not require mandatory wide-amplitude manoeuvres for high-quality compaction of the material. Changing the static torque of the operator while driving allows you to quickly adjust to different types of soil, and battery operation allows you to stay out of power for a while, which gives an additional advantage, especially important when working on remote construction sites.
