Abstract

The invention relates to the field of hydraulic engineering. The purpose of the invention is to simplify the production technology and increase the reliability of the structure. Namsh pressure. the constructions make 5 terraces formed on the main maps of the race by successively moving the front of the structure to the right side of the terrace. Terraces are arranged with a height not less than the thickness of the soil in the lower main map for the period of consolidation of the washed soil in the adjacent upper map. The clarified water is discharged to the catchment well 10 with a cascade of additional sedimentation tanks (DL) 6 through water outlets 12 arranged in cross sectioning . The spillway column IO is located in the TO 6 with the lowest water level in the latter. The height of the terraces is prescribed taking into account the preservation of the command levels of up to 6. 6 Il. 3

The invention relates to hydraulic engineering construction and can be used for the production of earthworks by sumping shells in the construction of earthworks, structures, mainly dams and spreading dams from local loamy soils on highly rugged terrain.

The purpose of the invention is to simplify the production technology and increase the reliability of the structure.

FIG. 1 shows a diagram of the washing of a pressurized structure from local materials, a plan view; FIG. 2, section A-A on FIG1.

The method is carried out as follows.

The washing of the pressure structure 1 of local materials begins with cutting the plant layer 2 of the soil within the quality part 3 of the structure - 1, while the dumps 4 of the plant soil are located on the side of the upstream. The main cards 5, which are located within the quality part 3 of the structure 1, and the additional settling tanks 6, located on the side of the upper wedge 7, are arranged by dumping the longitudinal 8 and transverse 9 dikes. At the same time, the main Maps 5 are placed along structure 1 in such a way as to form terraces repeating the terrain.

Terraces arrange a height equal to or more than the thickness of the layer of soil in the lower base map for the period of consolidation of the washed ground in the adjacent upper map. Compliance with this condition allows one to retain the command of the water levels in the additional septic tanks 6 and thereby discharge water along these septic tanks with a cascade while simultaneously washing and KOHCOlidation of the loamy soil in the adjacent main maps, as well as carrying out work in the case of organizational and technological processes.

Stands in separate areas of the facility. Before building 1, a spillway well 10 is erected, a collector 11J is laid by tubular waterways 12 in transverse embankment 9 and slots 13 in the dumps 4 of vegetable soil, and a drainage ditch 14 is developed from the collector 11

to the career of the dredger house. Moreover, the discharge well 10 and the collector II are arranged in the lowering, and the outlets 12 are arranged asymmetrically.

From the quarries, along the main slurry pipelines 15, the pulp is fed to the injected structure 1. The slurry is fed to the corresponding main map 5 by means of valves 16 and a distributing slurry pipe 17, laid on the overpass 18 from the uphill slope. In this case, erection of the structure 1 is carried out by one-sided dispersed layered soil. As the flow of pulp advances over the surface of the surface plow 19, larger soil particles are deposited in the main maps 5. The pulp with small particles of the soil is directed through slots 13 in dumps 4 of the vegetable soil to additional sedimentation tanks 6, where sedimentation also occurs. - tivofiltration element - screen. The clarified water with remnants of fine particles from the additional sedimentation tank is bypassed along the longitudinal axis 20 of structure 1 in a cascade through waterways 12 into the downstream additional sedimentation tanks to the spillway well 10. As a result, additional fine particles are deposited, which reduces the entrainment of soil with waste water. After we have the necessary layer of soil, the water pipe 12 is extracted and arranged at a higher level, while maintaining their asymmetry. The arrangement in the plan and ensuring the passage of water in a cascade through additional septic tanks 6. Then, after consolidation of the washed ground, the technological process is repeated and after the construction of the structure 1 in the areas with a lower height, its front is successively moved along terraced slopes.
