O) 2. Method. According to claim 1, from. In that the pulp produced from the upper part of the 117364 jiaiiopHoro pulpovod is discharged dispersed along the channel edge channel.

The invention relates to a technologist: the production of seNLriHHbix works by using projectiles when creating channel channels, collectors and other core sections.

There are known ways to develop the channel of the Channel, which includes the device of the removal of Ki dredgers in combination with the work of excavators, laying-gmi but co-excavation of pioneer trenches with profile external slopes 1 J.

The disadvantages of these methods are the difficulty in organizing the production of work carried out by different types of earth-moving machinery, is not very effective in the development of deep excavations and with the close occurrence of groundwater.

The closest to P13 acquisition is a method for developing the channel of the channel, including the development of excavation with dredging with soil overhang in the lower part of the slope and above the ot-i equipment in the upper part, removal of soil along the discharge slurry line of the dredge into the dump and forming 1 Slope 2.

The poor condition of the known method is the low quality and low efficiency of work on the device cross section of the channel channel in heterogeneous and connected connections in connection with the uncontrollability and duration of the process of self-treating the slope under water for these soils. In addition, when unfavorable:; Hydro-slugging conditions in the course of the work are possible the occurrence of a landslide, the elimination of which increases the total volume of the excavation by using land supplies.

The aim of the invention is to improve the quality and efficiency of development by regulating and accelerating the formation of slopes.

The goal is achieved by that according to the way of development and the channel of the channel and the development of the excavation

it is exhausted simultaneously with the OTKOSO.V formation, the latter being carried out by washing the soil from the upper part of the slope into the lower section of the slope with a stream of pulp taken from the upper part of the flowline.

In addition, the production of pulp taken from the upper part of the pressure p-pipeline is dispersed along the edge of the channel channel. FIG. 1 shows the design of the channel channel plan; FIG. 2 is a section A-A in FIG. 1, The method is carried out as follows.

in a way.

Dredging projectiles 1, for example, parallel strips 2, develop the excavation 3 of the channel of channel 4 with overrun 5 of the soil in the lower 6 part of the slope and a shortage of 7 soil in the upper 8 of it. The need to develop a channel excavation with a search of 5 soils from the lower 6 part of the slope and a shortage of 7 soils in the upper 8 of it, t, e, according to the principle

equal volumes, due to the fact that it is not possible for surviving land dredgers to work out the design cross section of the channel slope. In the process of developing sieves with 1 diving device, the 3rd water level in it is located. They are located on the border between the upper 8 and the 6th part of the slope. The developed soil along the pressure slurry dredger 1 is sent to the dump 10 .. previously fenced off by the embankment dam 11. Simultaneously with the supply of soil to the dump 10 from the top of the discharge slurry pipe 9

pulp is collected in a distributor, a pulp pipeline 12, from which it is directed through the pipes 13 dispersed along the edge 14 of the channel of the channel 4 to the area of the shortage 7 of soil. The resulting pulp flow 15 erodes the shortage of soil 7 to the project position. the upper 8 parts of the channel 4 channel are set by a given laying factor t. At the same time, the effectiveness of erosion of the soil shortage 7 increases with an increase in the difference between the ground surface and the water level in the recess 3 and with: a lower content of soil particles in the pulp coming from the nozzles 13 that is obtained by taking it from the upper part of the pressure slurry pipeline 9, where the particle content in its cross section is the smallest. The blurred soil of the shortage 7 and the soil coming from the pulp from the pressure slurry pipe 9 of the dredger and 1 are washed under the water at the search section 5 to form a prism 16 of the washed soil with otkhes 17, the coefficient of which per floor when washed into standing water is 1 : 3-1: 5. In connection with us of the additional soil contained in the pulp taken from the fallow pulp line 9 of the dredger 1, the volume of overpasses 5 must be greater than the volume of shortfalls 7 by an amount equal to the amount of soil entering through the patrabuk 13 of the distribution slurry line 12, the pulp flow taken from the pressure slurry pipe 9, influencing the processes of erosion of the deficiencies 7 and the closure of the overpasses 5, are regulated by valves and 19. riocjie working out the excavation 3 to the design slopes of the channel of the channel 4 at the site of the distribution slurry of the wire 12 of it together With the pressure slurry pipe 9, they are moved along the channel of the channel 4 in the direction of excavation 3 with dredgers 1 to the following: chastot, and the process of washing out the shortages 7 and the search 5 is repeated. Thus, when developing a canal excavation with dredgers while simultaneously eliminating undershoots and ground overruns with an adjustable pulp flow taken from a pressure piping line, you can get a transverse channel profile with slopes as close as possible to the specified, eliminating the possibility of landslides, which improves the quality and production efficiency hydro-mechanized earthworks for arranging extended PROFILE grooves. According to the proposed method, the organization of the work is greatly simplified and their efficiency is increased in setting up a channel channel with an upper gentle wave-resistant slope in the wave action zone. As a result of applying the proposed method for the construction of a canal in a dredging, the prime cost of developing 1 m of soil is 1.1 times less than that with the technology using dredgers and excavators that pioneer trenches along the contour of the excavation with specialized external slopes. In addition, the specific capital investment is reduced and the organization of work is simplified.
