SU1214853A2 - End link of slurry conduit - Google Patents

Description

The invention relates to the erection of embankments and can be used in the engineering preparation of the territory under construction, in mining, for land reclamation, in hydraulic engineering construction.

The purpose of the invention is the formation of an array with a homogeneous composition and the supply to the map of alluvial dissimilar granular soils.

Figure 1 shows the end link of the pipeline, the side view of figure 2 is the same, in plan view; on fig.Z - section aa on d.2.

The device comprises an end pipe 1, a retaining device 2 (chute), a stream 3 of pulp flowing from the end pipe, a stream 4 of pulp poured onto the flush card from the chute, guides 5 for the retaining device, a fastening element and a stop 6 of the retaining device, elements 7 articulations of the pore device with guides, end 8 of the end pipe, end 9 of the groove; border Yu of the lateral surface of the gutter, the washed out massif 11 (map of the alluvium).

The arrows indicate the direction of flow of pulp.

The device works as follows.

5 The pulp flow pours out of the end 8 of the end pipe 1, hitting the inner surface of the chute 2, partially quenching and moving inside it, changes its direction to

10 opposite, falling on the map of the alluvium 11,. Mainly through the ends 9 and partially through the curvilinear face 10 of the trench.

Alluvial front moves along

15 to the direction of the flow of the pulp pouring out from the end 8, and the washed surface has a slope in this direction: nii. Moving along the slope to a rise, the pulp quickly loses its speed under the action of gravitational forces and then changes its direction to the opposite, i.e., slowly moving under the slope under the action of the same gravitational forces.

25 At the same time, the flow develops a small speed, which makes it possible to deposit both large and small fractions on the map of reclamation, with their uniform distribution.
