Abstract

FIELD OF THE INVENTION The invention relates to hydraulic engineering. The purpose of the invention is to reduce labor costs, cost and construction time, improve the environmental performance of the method and increase the operational stability of the structure. First, the dredger house 4 is taken from the pit 2, interconnected with the reservoir 1, pulp is transported by the slurry line 5 to the structure 6. Then the body of the structure is poured to form a settling pond 12 for clarified water and then removed through the wastewater well 14 in the sump. The water from the settling pond 12 is discharged into the sump 15 and then returned to the pit 2, at the same time the pulp is collected and the total suspension mixture is subjected to sludge. The rest of the water infiltrating through the body of the structure is discharged into the reservoir 1 through inclined towards it, built uniformly over the entire area under the body of the structure in the rear pillar of the trough-shaped trenches 8, filled with filtering soil with one-sided construction of filtering protection. 85-90% of water is dumped into the sump 15, and 10-15%, respectively, into the river through trenches. 1 hp f-ly, 3 ill.

The invention relates to hydraulic construction and can be used in the construction of alluvial facilities, such as dams, dams, water dumps, etc.

The purpose of the invention is to reduce labor costs, the cost and time of construction, improve the environmental performance of the process, and reduce the operational stability of the structure.

FIG. 1 shows a scheme for implementing the method, a plan; in fig. 2 - section aa and pa of fig. one; in fig. 3 - section B - B in FIG. one.

The method is as follows.

Near reservoir 1, quarry 2 is being developed, into which water is supplied through channel 3 or by a pump through pipelines (not shown). From the pit 2, the dredger house 4 is driven into the pulp and transported by the slurry line 5 to the structure 6 erected on the base pelican 7, in which trough-shaped trenches 8 inclined towards the river, filled with filtering soil 9, i.e. With a soil with larger fractions m., which form voids between themselves more than between the body soil between the structures. The number and parameters of tranpep are determined by calculation, depending on the size of the alluvium map.

The structure 6 is formed layer by layer from the embankment dams 10 and the Rus 11 with the formation in the center of the construction of the pond-sludge pit 12, where they collect the clarified building 13, which is discharged through the water. waste well 14 and sump 15 and nakap-. P-1 is made up to a certain volume, providing water for pumping 16 or creating a certain pressure for a gravity flow. From the sump 15 water is fed back to the pit 2, which is used as a sump. In case pit 2 is located on the same bank of the river, where construction 6 is, sump 15 is positioned so as to ensure the flow of water into the pit by gravity.

If facilities 6 and pit 2 are located on different shores, sump 15 is pumped and fed through a siphon 17. In pit 2, an obt1 is formed, and a mixture is suspended in, and in free zones of the open pit, the mixture is sedimented and the soil fractions settle water discharged from the settling pond} 2 is reused in pulp composition, which reduces water consumption from the reservoir, improves

the environmental characteristics of the process by eliminating the discharge of water from the settling pond back into the reservoir, and reducing labor costs and construction costs associated with repeated clarification of the water and

construction for this special septic tanks.

The filtering soil 9 filling the trenches 8 is equipped with a filter protection 18 that is one-sided in the direction of the structure 6, which can be made integral with the anti-filter screen of the structure, i.e., as a continuation of the structure.

Claims (2)

1. A method for erecting a precoat structure, including collecting a pulp of a dredger from a quarry interconnected with a water body, transporting pulp from a building to the structure, washing the body of the structure to form a settling pond for clarified water in it and then removing it through a spillway into the septic tank. characterized in that in order to reduce labor costs, cost and construction time, To improve the environmental performance of the method and increase the operational stability of the structure, water from the settling pond is dumped into the sump and then returned to the quarry, which is used as a settling pond, while 5 temporarily collecting the slurry and exposing the total suspended mixture to sludge, and the rest of the infiltrating structure through the body water is discharged into the reservoir through inclined to the canopy, uniformly executed over the entire area under the body of the structure in the rear pillar of the trough-shaped trenches filled with filtering ground with one-sided in the direction of the construction of filter protection. five 2. The method according to claim 1, characterized in that 85-90% of the water is discharged into the sump, and 10-15%, respectively, into the river through the trenches. ten 7  LLLI-. , 0 / - 18 (reg. yy Srig.
