Abstract

There are many sources of pollution on the territory of the city: enterprises, transport, and also a large negative impact is during the construction work. The article examines the impact of construction machinery and works on the soil, namely soil contamination with oil-containing products. To minimize such an impact, the process of penetration of the most common oil-containing substances into the soil was simulated in laboratory conditions. To minimize such an impact, the process of penetration of the most common oil-containing substances into the soil was simulated in laboratory conditions. In order to obtain a more accurate result, the granulometric composition of the soil of the urban area was determined at the initial stage. further studies were carried out with a similar soil. Kerosene, diesel fuel and gasoline were used as oil-containing liquids in the studies. A methodology for conducting laboratory tests was developed. To identify the dependence of the volume of liquid entering the ground surface and the depth of penetration, its studies were carried out for three volumes: 50 ml, 100 ml and 150 ml. A series of experiments (at least 10) was conducted for each liquid and each volume of liquid under study. The results of the studies were recorded for 48 hours at the same intervals in each series. The results of the experiments were recorded in tabular form, then analyzed statistically and graphically. During the analysis, it was found that gasoline and kerosene penetrate into the ground faster and reach half of the maximum penetration depth in the first 30 minutes. Diesel fuel penetrates more slowly and more evenly throughout the entire time of fixing the penetration depth due to its higher density. Based on the results of the research, recommendations were formulated for the use of contaminated areas after the completion of construction work, and measures were proposed to minimize the negative impact of pollution on the ecosystem.
