TECHNOLOGICAL EQUIPMENT FOR PERFORMING SELECTIVE CAPITAL REPAIR OF PIPELINES

Mykola Biliakovych Yuriy Varfolomeev Yevhen Vysokovych Andrii Koval Volodymyr Musiiko

The article provides an analysis of the technical condition of main pipelines and technologies for performing selective overhaul of their linear part. Known technological schemes for performing selective repair of pipelines do not provide for effective soil compaction after its completion due to the lack of technical means for effective and uniform soil compaction. The lack of compaction of the soil under the repaired pipeline leads to its uncontrolled subsidence relative to the line of original laying, which can cause an emergency situation. In order to ensure high-quality, fast and safe execution of the entire complex of earthworks during the selective overhaul of main pipelines with one excavator, a research and industrial universal set of interchangeable work equipment for a single-bucket crawler excavator weighing 20 tons has been designed, manufactured and tested. The set of replacement equipment consists of digging equipment, compaction equipment, a bucket for performing earthworks during the opening of the pipeline and filling the soil in the trench, a universal grip for attaching the replacement equipment to the handle of a single-bucket excavator, a system for positioning and monitoring the position of the replacement equipment relative to the pipe. Technology for implementation of earth-moving works at capital repair of linear portion of main pipelines and complex of technological equipment for its realization are patented in Ukraine. The productivity of digging equipment is 35...55 m3/h, the productivity of compacting equipment is 35...45 m/h. The use of a set of equipment allows one excavator to perform the entire complex of earthworks during the selective capital repair of main gas pipelines with a diameter of 530...1420 mm
