Technological features of the ducker device for transportation of petroleum products

Abstract

The efficient operation of main oil pipelines - one of the most important and urgent problems of Russia. Ducker - one of the most technologically advanced stages of construction of the road trunk pipeline. It is important to make the right choice of the method for installing the pipeline, since the speed of construction, economic costs of work, the reliability of the underwater crossing section, and, as a consequence, the uninterrupted operation of the entire main oil pipeline, environmental friendliness of both the installation and further operation will depend on this. underwater passage. Thus, the purpose of this work is to perform a comparative analysis of the methods for the construction of siphons, highlighting the advantages and disadvantages of each method. The results of the work can be applied in the construction of a new route, as well as in the overhaul of underwater crossings that have worked out their time.

Technological Installation Drawings of Roof Construction and Suspended Ceilings Using Combined Method

“…The diagram (fig. 1) shows three options for the sequence of installation of coating structures and suspended ceilings using combined method when the installation crane moves across the spans [5]. The first installation option -with the shuttle movement of the crane across the spansallows you to assemble building elements along its entire width by one step, i.e., 12 metres, in one crane pass.…”
