Since the beginning of the era of the development of Western Siberia designers and builders of various linear structures encountered with conditions of weight construction – permafrost, moorland and plenty of natural obstacles (water reservoirs, lakes, rivers and streams). Pipeline construction has felt it on itself – any error in the calculations could lead to losing of stability of the structure in the longitudinal direction. To ensure the design position of the pipeline began to develop special designs ballasting devices and anchors, each of which has some shortcomings, limitations on the use of technology and features of the work. Scope of each design, the calculated position, as well as their geometric characteristics were specified in the technical standards of the time. Currently, the use of a ballasted device requires to confirm the technical and economic calculation, and the number of the means of anchors significantly decreased.This article describes how to anchorage the buried trunk pipelines in the swamps. For this purpose we consider the classification of swamps, the area of distribution, and the appropriate constructive ways of laying trunk pipelines and forms out of the design position. Considered used at different times means ballasting and secure the lines and offers their classification. According to the analysis of structures set their shortcomings and propose a new design of the vacuum anchoring device embodying the pipeline design position in the swamps. The principle of operation is based on the design of the bearing capacity of the soil and the suction phenomenon arising between the anchors and the foundation soil.
