Abstract

FIELD: civil engineering. SUBSTANCE: embankment includes clay in mixture with straw 2, soil 5, crushed stones 6, as well as reinforced concrete members 1. Each reinforced concrete member has three rigidly joint at right angle flat planes as constituents. Two plates are vertical and the third one is horizontal, triangular. Members 1 are installed as vertical rectangular plates along embankment body to originate gaps between faces of adjacent members. Gaps 4 are filled with straw/clay mixture as anti- filtering material. Faces of adjacent members 1 are interconnected with diaphragms. EFFECT: aseismic effect. 8 dwg

Description

 The invention relates to construction and can be applied in seismic regions, as well as in regions with intense rainfall.

 A technical solution is known, including film antifiltration elements and soil backfill with layers, in which the layers are closed in shape with one inside the other, and film antifiltration elements are placed along the outer contour of the backfill of each layer with separation along the perimeter of adjacent layers of the backfill.

 Its disadvantage: wrapping each layer of soil backfill with film antifiltration elements gives nothing to increase seismic resistance. Under load, the soil will press the film down at intervals. The underlying soil layer (below the film) will squeeze the film up in places. As a result, the film will not represent a horizontal plane, and therefore, there will be no sliding of one layer of soil over another with the help of a film. However, films cannot increase seismic resistance.

 The purpose of the invention is the increase of seismic resistance, reliability and the elimination of erosion during heavy rains.

 This goal is achieved by the fact that the embankment, including the layers of soil backfill and antifiltration material laid in its body, is equipped with reinforced concrete elements and dampers, while reinforced concrete elements are installed in the middle of the cross section of the embankment, and each of its elements is made of three rigidly connected under a straight line the angle of flat slabs, two of which are vertical rectangular, and the third horizontal triangular, and the elements are installed by vertical rectangular plates along the body of the embankment with cm gap between parallel sides of adjacent elements, wherein said gaps are filled with impervious material, which is used as a mixture of straw with clay, and the edges of adjacent elements are interconnected dampers.

 Figure 1 presents the embankment in plan; figure 2 section aa in figure 1; figure 3 section BB in figure 1; figure 4 section bb in figure 2; figure 5 reinforced concrete element; in FIG. 6 is a view along arrow D in FIG. 5; in Fig.7 connection of adjacent faces of reinforced concrete elements with dampers; Fig.8 is a view along arrow D in Fig.7.

 The embankment includes reinforced concrete elements 1 made of three flat plates rigidly connected at right angles, vertically aligned along the embankment, with a clay layer mixed with straw 2, clay laid in the base of the embankment with straw 3 filling the gap 4 between vertical faces of reinforced concrete elements, soil 5, gravel 6, sprinkled at the top of the embankment, dampers 7 made of a steel sheet in the form of a horseshoe and attached to embedded parts 8 by electric welding 9. In figure 3, 10 is water.

 Erect a mound in this order. Lay the clay layer in a mixture with straw 2 (figure 3). After the clay has dried, the reinforced concrete elements 1 are laid in a mixture with straw 2 (Figs. 1-3). Then, dampers 7 are attached to adjacent faces of the reinforced concrete elements (Fig. 7). The gap 4 (FIGS. 2 and 3) is clogged (filled) with clay mixed with straw 3 (FIGS. 2 and 3). Pour soil 5 (Fig.2-4) layers with a seal. Carefully waterproof the dampers 7 (FIGS. 4 and 7) by any known method. After this, crushed stone 6 is poured (Fig. 3).

 The embankment works as follows.

 When seismic impacts reinforced concrete elements 1 (Fig.1-4) will slide along the clay base 2 (Fig.2). Between themselves, reinforced concrete elements will allow clay 3 to slide (Fig.2-4). These slip and reduce the magnitude of the seismic load on the embankment. Dampers 7 (4 and 7) will absorb the energy of seismic waves, absorb it.

 Reinforced concrete elements 1 (Fig. 3) and clay with straw 3 (Figs. 2-4), which fill the gap 4 (Figs. 2-4) between the vertical faces of the reinforced concrete elements, will save the embankment from erosion by heavy rains.
