For cyclone technology non-excavation repair of small and medium-diameter buried pipelines, the construction period has no fixed value and will fluctuate according to the length, diameter, and complexity of the working conditions. For a single continuous construction of 1 kilometer of pipeline, the overall construction period is about 5-10 days, which is 50%-70% shorter than traditional excavation construction. Core factors affecting the construction cycle: Pipe length: The maximum single continuous construction of cyclone technology can be up to 2,000 meters. The longer the length, the overall cycle will increase proportionally, but segmented operations can also maintain efficiency. The overall construction cycle of a 2,000-meter pipeline does not exceed 20 days. Pipeline condition complexity: If the pipeline has many turns, diameter changes, and branch nodes, the process parameters need to be adjusted, which will increase the construction period by 1-3 days compared with straight pipelines. Preparation time: It is necessary to survey the actual direction of the pipeline, assess the corrosion situation, and match process parameters in advance. This process usually takes 2-3 days and does not take up on-site construction time. For comparison, referring to public trenchless engineering data, for buried pipelines of the same length, the traditional excavation and replacement construction period is generally 15-30 days, and the construction period advantage of cyclone technology is very obvious.
