Oil and gas transmission pipeline laying and mounting construction method

Abstract

The invention relates to an oil and gas transmission pipeline laying and mounting construction method. The oil and gas transmission pipeline laying and mounting construction method comprises the following steps: line determination, base construction, bracket mounting, pre-laying, aligned adjustment, connection and fixation, detection and recording and the like. Adjusting and docking equipment usedin the aligned adjustment step comprises a mounting bed frame, auxiliary mechanisms are symmetrically arranged at the left and right ends of the mounting bed frame, and a locking mechanism is arranged on each auxiliary mechanism. The oil and gas transmission pipeline laying and mounting construction method can solve the problems in an existing line pipeline laying process: a, the pipeline dockinglabor intensity by manual control is great, and the follow-up welding effect of the pipelines is affected as the uniformity of gaps in connecting parts of pipelines cannot be guaranteed; and b, it iscomplex to operate by controlling the pipelines to dock mechanically, corresponding machinery is selected for pipelines of different specifications, and the labor intensity is great and the work efficiency is low as pipeline docking machinery needs to be carried according to a mounting line.

Description

technical field [0001] The invention relates to the technical field of pipeline laying, in particular to a method for laying, installing and constructing oil and gas transmission pipelines. Background technique [0002] Natural gas, oil and other resources are transported by pipeline, which not only reduces the cost of transportation, but also reduces the loss during transportation. In order to ensure the safety of the pipeline, the pipeline must be buried in the complex traffic environment and geographical location. Underground, the construction of buried pipelines requires various processes such as digging, laying pipelines, pipeline docking, fixing, welding and pipeline inspection. The pipeline laying line is long, and the pipeline docking process plays a vital role in pipeline construction. [0003] However, the following problems exist in the laying process of existing line pipelines, a. Manual control of pipeline butt joint is labor-intensive, which cannot ensure the u...

Problems solved by technology

[0003] However, the following problems exist in the laying process of existing line pipelines, a. Manual control of pipeline butt jointing is labor-intensive, which cannot ensure the uniformity of the gaps at the pipe joints, which affects the effect of subsequent welding of pipelines. , Pipelines of different specifications need to choose the corresponding machinery, and the pipeline docking machinery needs to be transported according to the installation route, which is labor-intensive and low-efficiency

[0004] Regarding some problems existing in the process of pipeline laying and docking, related industries have made research and proposed specific technical solutions, such as the Chinese invention patent oil pipeline docking equipment with patent number 2016103847451, which is convenient for installation of oil pipelines and is not easy to damage Oil pipelines, however, the problems mentioned above in the process of laying and connecting pipelines are not covered
