Abstract
The article proposes a new solution for laying an oil pipeline with the help of a repair pit, which allows to preserve the fertile layer of the earth, which is difficult to restore after conventional work in the traditional way. An analysis of the occurrence of defects was carried out and a conclusion was made about the criteria and operating conditions of the oil pipeline that affect their occurrence. As a novelty, the scheme of the repair pit of the main oil pipeline is proposed. The proposed novelty will significantly optimize and increase productivity during the reconstruction of the main oil pipeline. This method is distinguished by simplicity, as well as the preservation of a fertile soil layer, which is quite important in the conditions of the sharply continental climate of the oil pipeline area. The ongoing reconstruction of the pipeline will allow replacing defective sections of the pipeline, thereby increasing the service life and avoiding accidents on the pipeline, which is quite an important factor in the conditions of uninterrupted supply of petroleum products to the consumer.
