FIELD: construction.SUBSTANCE: group of inventions relates to construction and can be used in construction of trunk pipelines in the third category of swamps, in production of underwater works, in the area of permafrost spreading, with rapid erection of roads, airfields, engineering infrastructure facilities of the military-industrial complex and the Ministry of Emergency Situations, sports grounds, strengthening of the coastal strip and various slopes, in particular, in the construction of ground coverings. Ground module, consisting of not less than five made of flexible elements and filled with bulk soil located X-shaped or cruciform cells, is provided with protective walls made of flexible elements, a sewn bottom, which is fastened to the faces or ribs of the cells. Options of the ground module provided with a cover are given. Sewn bottom is made of culvert or is provided with culvert, the outer and inner walls of said cells are provided with water-passing elements, and the lid is provided with air or water-passing elements. Range of technical means is expanded. Erection of engineering structures during subsea operations, erection of soil bases in the marshes of the third category, the depth of which considerably exceeds the height of the soil modules is ensured, while eliminating soil leaks from their cells. Invention allows to increase the load-carrying capacity of the bases of main pipelines, roads and other structures, including the repeated application of a local, impact mobile load, and also allows to increase the service life and reduce the costs and time for the maintenance of the constructed industrial sites. Allows to exclude use of imported mineral soil due to use of local soil, including dusty clay fractions, as well as permafrost soils.EFFECT: invention is effective in construction on loamy and clay soils.36 cl, 11 dwg
