Abstract

The invention relates to the field of hydraulic engineering construction. The purpose of the invention is to increase the reliability of diverting the flow of a river from a seam to a bank. work efficiency due to the preservation of the throughput capacity of the pioneer trench (PT) and silting of the excluded river loop. To divert the flow of the river 1 from the eroded bank 2, the PT 5 is designed under the cover of the diverting channel 3 at the U / U route of the excluded river loop 4 under the cover of jumper 7.

Description

The invention relates to the technology of hydromechanization, to methods for the production of channeling works by means of hydromechanization, for example, when diverting a stream from a spreading bank to a spreading channel.

The purpose of the invention is to increase the reliability of diverting the flow of a river from a spreading bank and the efficiency of operations by maintaining the throughput of the pioneer trench and silting the excluded river loop.

Fig. 1 schematically shows a rectified river bed, top view; figure 2 - section aa in figure 1; on fig.Z - section bb on phi, g.1.

The method is described as follows.

In order to divert the flow of the river 1 from the eroded bank 2, preliminary, along the route of the diverting channel 3, in the section of the river loop to be excluded, 4 are using suction-projectile projectiles

Further development of the diverting channel 3 to the design section is carried out by self-erosion by directing water to the pioneer trench 5, for which jumpers 7 and 8 are opened.

In the process of opening pempek 7 and 18, the production, pressure and overlapping of the riverbed 1 alluvial jumpers 20

Q For this, the ground is developed by suction dredges 21, and the slurry pipelines 22 transport it to the end of lintel 20, which is produced in the direction to the retired longitudinal

Claims (3)

Soil in the development of the pioneer, Invention Formula 5 trench is laid in the form of a retired Longitudinal dam 11, which is the way to straighten the river bed, outside the control channel 3 on the side of the river loop 4 to be excluded. Simultaneously with the development of the pioneer trench 5, at the site of the upper river loop 12, suction projectiles arrange a discharge slot 13, the inlet area 4 of which is shaped as a socket, and the outlet section 15 is located opposite the inlet section 6 in the pioneer tran. neck 5, so that its longitudinal axis 16 intersects the longitudinal axis 17; the pioneer trench .5 under the sharp angle d. The development of the discharge slot 13 is carried out under the cover of jumper 1B with the soil dump from the side of the river loop 12. At this bottom 19, the discharge gate 13 arranges the same pattern as the bottom B of the inlet section 6 of the gionionerne trench 5, above the bottom 9 of river J to height not less than the height of the channel channel mesoform 10. Further development of the diverting channel 3 to the design section is carried out by self-erosion by directing water to the pioneer trench 5, for which jumpers 7 and 8 are opened. In the process of opening pempek 7 and 18, the production, pressure and overlapping of the riverbed 1 with alluvial jumper 20. For this, the soil is developed by suction dredgers 21 and transported via the pipelines 22 to the end of lintel 20, which is produced in the direction to the retired longitudinal dam 11. Simultaneously with the constraint and overlapping of the riverbed I of river I by bridge 20, the soil is dispersed into the stream of a river loop 12. suction dies 23 unloading slot B 13. In this case, a part of the ground, which is dispersedly fed into the stream of the upper river loop 12, is moved to the excluded river loop full saturation of the flow of the soil in the alignment. After blocking the river bed with a jumper 20 on the section excluded 4, silting it and creating an additional loop 4, cut-off dams 24 are arranged. including the construction of a pioneer trench at the section of the excluded river loop with a bell-shaped entrance section developed under cover of the lintel, washing the trench with a free-flow water flow with simultaneous overlapping of the river channel by pouring soil into the stream; the sides of the river loop to be excluded outside the forming diverging channel, characterized in that above the reliability of diverting the flow of the river from the eroded bank and the efficiency of work by maintaining the pioneer trench's carrying capacity and silting the excluded river loop, a discharge pro- ject is arranged on the upper river loop. rez with an entrance site in the form of a bell, the output site located opposite to an entrance to pioneer 31444А62 The trench and the longitudinal axis, the transverse slot and the inlet section, and the penetrating longitudinal axis of the pioneer tranny transgene are installed above the neck at an acute angle, with the discharge at a height not less than the height of the discharge slot of the implemented mesoform. luy along with the development of pio an uneven trench, and the overlapping of the river bed is produced with a simultaneous dispersed supply of soil into the upstream river loop. 2.
