Abstract

FIELD OF THE INVENTION The invention relates to hydraulic engineering. The purpose of the invention is to expand the functionality of the method by increasing the range of intensity of soil dumping, increasing the reliability of the structure and improving its anti-filtration properties. The rest of the soil is carried out on a dry card bounded by embankment dams 1, to reserves 2 in the form of separate prisms or unclosed rows. Next, the card is filled with water up to level 3. The lower part is soaked in reserves up to a water saturation value of not more than 0.8, then the soil from the upper parts of reserves simultaneously with the ground additionally supplied to the card at this time is transferred to the water. Thus reach the required thickness of the layer of dumping. In order to increase the reliability of the structure and the foundation, to improve their anti-filtration properties, a layer of filter material is initially poured within the map, which is used to adjust the level 3 of water in the pond during the dumping process and to drain the filtered water through the valve 6 on the pipe removed. bottom dam limits. The soil can be poured into reserves with a continuous layer of calculated thickness or with a layer of variable thickness gradually increasing in the direction of dumping. 2-z. P. f. 3 il.

FIELD OF THE INVENTION The invention relates to hydraulic engineering, in particular, to the technology of erection of land structures,

The aim of the invention is to expand the functionality of the method by increasing the range of intensity of dumping soil, increasing the reliability of the structure and improving its anti-filtration properties.

On fig, 1, a map is presented with otststannom.v it dry reserve, placed in the form of rows of continuous or individual prisms in them, the plan; Fig. 2 is a map having at the base a layer of filtering soil with a reserve poured into separate prisms, a slit; in FIG. 3, a reserve, measured by a continuous layer of a constant thickness map over the area.

The method is carried out in the following sequence.

In a dry map, bounded by embankments of 1 embankment, erected dry with a layer-by-layer rolling from the same soil as the structures, are dumped by soil into reserves 2 as separate continuous rows or individual prisms into a row. Then, water is supplied to the card, which fills it to a depth of 3, which is 3/4 of the height of the embankment dams. After keeping the soil in the lower part of the prisms in reserves (to a water ratio; Enough 0.6-0.7}), the card is filled with the soil with a layer of the required thickness by pouring it into the water while simultaneously moving the unwatered soil from the upper parts of the reserves. This filling of the map is carried out with an intensity that provides the necessary final saturation of the soil (0.85j. If there is a filtering layer 4 at the base of the map (sand or sand-gravel mix), the soil is placed on it or in separate rows of 1F D.2) or a layer of constant thickness (fig.Z), or a layer of variable thickness, increasing gradually from

the beginning of the map towards its end in the direction of movement of the dump front. The water then supplied to the map, falling into the filtering layer, is full of reserves in the reserves to the calculated values determined by the time of water interaction with the soil. Further, additional soil 5 is fed into the map, which is poured in the usual manner (using the method of pouring into water) until the required thickness of the layer of filling is achieved. The filtering layer 4 allows water to be drained from under the base of the card through the pipe with valve 6, which is brought out of its bounds. The card should be planned so that there is a slight bias towards this water diverter.

Claims (3)

1. A method of erection of land structures, consisting in dumping soil into water, characterized in that, in order to expand the functionality of the method by increasing the range of intensity of dumping soil, soil is initially dumped in the form of open rows in the reserves within the map, then the card is filled with water, and then the soil from the upper part of the reserves and additionally supplied to the card is moved into the water, filling the space between the rows until the required layer thickness is reached. 2. Method non.i, characterized in that, in order to improve the reliability of the structure and improve its anti-filtration properties, a layer of filter material is initially poured within the card with the possibility of filling the card with water after it is filled. 3. The method according to claim 2, with the difference that the soil is poured into reserves with a continuous layer of the calculated thickness or with a layer of variable thickness, gradually increasing in the direction of dumping.  VVVF I I / / jaz
