The method of construction of earth structures in the far north regions with high environmental requirements

 

The invention relates to oil and gas construction and used in the construction of roads and field roads, shrubs and grounds in the Far North, which are increased environmental requirements for this type of construction. The method of construction of earth structures in the Far North includes the selection and creation of geodesic laying the foundations of motorway roads or construction sites and filling or alluvium soils in the body of earth structures. What's new is that the selection and creation of geodesic laying the foundations of roads carry through flooded areas - lake, sites under construction and shrubs in the borders of these lakes, and the dumping or alluvium earthworks produce their melt the base, and the construction of earth structures made from local podozernaya sandy soils, mainly dredging methods and in the summer, and the construction of bridges embankments of roads between the lakes on frozen ground, dumping of frozen soils in winter. The technical result of the invention is the reduction of the alienated land area for the construction of earthworks and Amenti and reliability of their construction in the irrigated regions of the Far North. 2 Il.

The invention relates to oil and gas construction and used in the construction of roads and field roads, playgrounds and bushes in the Far North, which are increased environmental requirements for this type of construction because of the uniqueness of the region: for example, the Yamal Peninsula.

There is a method of construction of earthen structures in the Far North, including the selection and creation of geodesic laying the foundations trails roads or sites under construction, mainly in the crawl found along lakes, preparing their foundations on collapsible and selenoproteome soils and layered or solid filling on these grounds earthen constructions of imported soil. (See Earthworks. Builder's guide. M.: stroiizdat, 1984, S. 172-190 and Highway Yamal Peninsulaā€¯. Section of the project / Giprotyumenneftegaz. - Tyumen, 1985).

The disadvantages of this method are that the construction of earthworks in areas with high environmental requirements needs in the alienation of large areas of land that leads to a deadweight loss and destruction trudnoperevarivaema majorscale neobhodimosti expectations equilibrium temperature of soil Foundation and osypaemy layers and in this regard, greater complexity of work, so practice using mainly solid heaping structures on permafrost base, where in the summer season for violating the heat balance between the frozen icy grounds and building, filled from the melt to the ground and having a positive temperature occur focal degradation of permafrost soil grounds, leads to numerous deformation, sediment and destruction erected their buildings, waterlogging and gaining their slopes. In addition, the method includes delivery of soil from the base of the pits of Yamal, located typically at a distance of 30-40 km from the construction site, which makes this method very expensive and therefore ineffective (see Fig... 1.).

The closest to the essence and the achieved technical result is a method of construction of earthen structures in the Far North, including the selection and creation of geodesic laying the foundations of motorway roads or construction sites and filling or alluvium soils in the body of earth structures (see, for example, Excavation work, Builder's Guide. M.: stroiizdat, 1984, S. 49, 50, 172-190).

Dera, including the selection and creation of geodesic laying the foundations trails roads or sites under construction and filling or alluvium ground structures, is that the selection and setting of traces roads carry through flooded areas - lake, sites under construction and shrubs in the borders of these lakes, and the dumping or alluvium ground structures produce their melt the base, and the construction of earth structures made from local podozernaya sandy soils, mainly dredging methods and in the summer, and the construction of bridges embankment road between the lakes on frozen ground - the dumping of frozen soils in winter.

The technical result of the invention is the reduction of the alienated land area for the construction of earthworks and reduction of the negative environmental consequences, as well as reducing transport costs and improving the sustainability and reliability of their construction in the irrigated regions of the Far North.

In Fig. 1 shows the method of construction of earth structures in the traditional way - in bypass water obstacles, which designated the following positions: Speedway 1; dry digging pit 2; cluster the room the way where indicated the following positions: Speedway 1; hydrocharger 2; well pad 3, construction site 4; the dredge slurry pipeline 5.

The method is as follows (Fig. 2). In the area of construction of earth structures: roads 1 or sites 3, 4, such as condensate or oil field, Yamal Peninsula, where due to the large number of lakes, the water content is 40%, when the depth of the lake 0.3 - 1.5 m, make the selection and creation of geodesic laying the foundations trails roads 1 through these lakes, having, as a rule, thermokarst origin, and sites under construction and bushes 3 and 4 in the borders of these lakes. Moreover, the construction of earth structures made from local podozernaya sandy soils hidrocarburos 2, mainly dredging ways by submitting a soil slurry pipelines 5 to melt the basis of the lakes, and in the summer season, and the construction of bridges embankments of roads between the lakes on frozen ground - dumping and in the winter.

In the filling or reclamation of soil on the grounds that it is equal or close positive (in summer) or negative (winter) temperature decreases the heat exchange process earthen structures. Due to the environment of the construction water water area is significantly reduced dust tundra fine soil particles, Stevenage winds from the surface of earth structures.

Thus, the application of the method will significantly reduce the area of alienated land under construction in the Far North regions with high environmental requirements, create new undeveloped land area in the region, to improve the stability and reliability of the construction of earth structures and to reduce the dust majorscale cover tundra. Furthermore, the method does not require reclamation along quarries and sites under the provisions of soils due to their location within the natural boundaries of flooded thermokarst depressions and lakes.
