The invention relates to methods for erection of bulk earth structures and can be used in the construction of dams, dams, jumpers of dissimilar soils for the needs of water management in various parts of the national economy.

According to the main author. St. No. 848527, a method of erecting bulk structures is known, which includes layered dumping in the construction of pre-dried pieces of clay and filling the space between them with sand, after which they are moistened to the natural moisture of the clay soil.

However, the process of filling the space between the pieces of clay is not controlled, and this reduces the quality of the bulk structures, and therefore the filling of the pieces must be done in a thin layer.

The purpose of the invention is to increase the reliability of the structure.

This goal is achieved by the fact that, according to the method of erection of the bulk structures, after filling the space between the clay pieces with sand, the slits are cut to a depth equal to the thickness of the covered clay pieces, followed by moistening them to natural moisture.

The drawing is a diagram explaining the method.

In the drawing indicated: the bottom layer of pieces of clay 1, the upper sand layer 2.

The method is carried out as follows.

When cutting gaps in the lower layer 1 of the pieces of clay behind the knives of the chink, cavities are formed into which sand spills from the upper layer 2, which makes it possible to distribute it evenly along the height of the clay-like layer. of that Moisture when moistening the dust penetrates over the entire height also more evenly. As a result of cutting gaps in the process

moistening of dried pieces of clayey soil causes swelling forces evenly throughout the layer. The sand spilled between the pieces and in the cracks is introduced into the surface of the pieces, with the result that the monolithic layer of the structure is achieved. Subsequent layers are poured after moistening the previous one.

The amount of water for moistening is determined by calculation depending on the volume of the soil laid in this layer, their moisture content during laying and the natural moisture content of the applied soil for the construction of the structure.

The number and depth of the gaps allows you to adjust the amount of sand and other stages of the technology.

The invention makes it possible to control the process of filling the space between the pieces of clay, as well as the depth of sand embedding and its uniform distribution, which improves the quality of molding the bulk structure layer and makes it possible to increase the thickness of the clay layer during dumping.

St. No. 848527, characterized in that in order to increase the reliability of the structure, after filling the space between the pieces of clay with sand, they cut the cracks to a depth equal to the thickness of the sprinkled layer of pieces of clay, followed by moistening them to natural humidity.
