Oil pipeline parallel section construction technology

The invention belongs to the field of oil pipeline construction, and particularly relates to an oil pipeline parallel section construction process which comprises the following steps: firstly, surveying and setting out before construction to ensure that a pipeline pit slot is straight, and then digging according to the diameter of a pipeline and the number of parallel pipelines to enable the width and depth of the pit slot to adapt to related parallel pipelines; the method comprises the following steps: firstly, pre-laying parallel pipelines, placing a plurality of sections of parallel pipelines in a pit, carrying out parallel detection on the head and the tail of a single section of parallel pipeline by using a pipeline parallel detection device, comparing the distance difference between the parallel pipelines at the head and the tail, and judging whether the two parallel pipelines are parallel to each other or not, and by arranging four clamping blocks, the two parallel pipelines can be clamped; by setting
