Experimental Research of Physical and Mechanical Characteristics of Reclamation Pipelines Made of Composite Materials

Purpose of research. Improving irrigation methods and techniques is the most important task of irrigated agriculture. In our country and abroad, a significant part of the area is watered by surface irrigation along furrows, strips and checks, which is most acceptable in the case of a sharp increase in the cost of energy carriers. More and more attention is being paid to the introduction of mechanical aids and automation of surface irrigation, as well as the development of various effective ways to distribute water across the field and reduce its losses. This is successfully achieved by using flexible lay­flat pipelines for irrigation. To increase irrigation productivity, improve quality and reliability, it is advisable to use structures with a reinforced seam or seamless lay-flat pipelines. The goal and objectives of the paper are the following ones: improving surface irrigation methods through the use of flexible reclamation pipelines that increase irrigation productivity and ensure efficient water distribution across the field; obtaining experimental characteristics of pipelines. Methods. According to the technical requirements and operating conditions, various physical and mechanical tests of fabric frames, polymer film coatings applied to the frame and pipelines with these coatings have been carried out. The experiments have been performed according to standard methods, as well as on a developed special installation. Results. The undertaken experiments confirmed the compliance of lay-flat pipelines with the technical requirements. Conclusion. The developed seamless and reinforced technological seam lay-flat pipelines have increased strength and performance characteristics, which allows you to improve surface irrigation methods and ensure the efficiency of water distribution across the field.
