Embodiment Construction
[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0033] like Figure 1 to Figure 5 As shown, a method for laying and installing oil and gas transmission pipelines, step 1, determine the line, use a leather tape to measure the line of the pipeline laying line, use white lime to mark along the path measured by the leather tape, the thickness of the white lime is 5-7 mm;
[0034] Step 2. Foundation construction. Use an excavator to dig out the installation pit at the position marked in step 1, transport the soil in the installation pit, use a rammer to tamp the installation pit, and pour concrete into the installation pit at an interval of 3-5m. Cement platform, the thickness of the cement platform is 10-20cm;
[0035] Step 3. Bracket installation. Use a drilling machine to drill installation holes...

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...
