Abstract

The invention relates to the field of hydraulic engineering. The purpose of the invention is to improve the processing technology and simplify the further use of ameliorants in agriculture. Initially, they arrange pits 4 with hollow walls and a bed that has a slope towards dam 1, with a depth not exceeding the freezing depth. The pulp in winter conditions is supplied from a number of pulping outlets 10, each of which has a section with a perforated base above the pit 4. Then the pulp is frozen in the frozen state and transported to agricultural land, where it is evenly placed on the snow surface in the direction of the furrows, which are arranged to occurrences of snow cover. 2 Il.

Description

The invention relates to hydraulic construction, in particular, to methods for producing material as an alluvial product, which can be used in agriculture, in construction.

The purpose of the invention is to improve the processing technology and simplify the further use of ameliorants in agriculture,

Figure 1 shows the outline of the map of the alluvium with pits; figure 2 - pit, cross section.

Figures 1 and 2 are designated fencing dam 1 of the inlet structure, drainage 2, slurry pipeline 3, trenches 4 with gentle walls, settling pond 5, drainage well 6, perforated base 7, alluvium map 8, drainage section 9 of the excavation and pulp drain 10. Arrow A shows the direction of movement of the pulp.

Example. Initially, a ditch of 20–30 m long, 15–20 cm wide with a base slope towards the enclosing dam 1 and a depth not exceeding the freezing depth is arranged on the map 8 of the inlaid state. Pulp outlets 10 are placed along the axes of the trenches. In this case, a part of the pipe (pulp-release) is made with perforations at the base with a hole diameter greater than 2-3 times the maximum particle size, and the discharge is carried outside the pit. The length of the plot with perforated base is 723m.

After the pulp is fed through the slurry pipeline 3 (direction of arrow A), several (3-4) releases are simultaneously put into operation.

10. Due to the low flow rate at each outlet, the solid phase of the flow is concentrated mainly at the bottom of the pulp line (bottom mode) and in the area with perforated base 7 enters the pit 4. The main flow rate of the water component with a small amount of the finest ash particles goes to map 8 and alluvium and then into the settling pond 5.

Due to the multi-jet pulp coming from the perforated base 7, high heat losses occur. However, at the initial moment of filling in the trenches 4, the washed deposits are in a thawed state due to the thermal flow margin. As the thickness of the washed layer changes in the hydraulic mode (formation of a single layer stream) and stabilization of the drainage process of the water component, the influence of the channel on the temperature mode of the sediments decreases: the water component of the pulp stream through the previously formed filtration pass through the body of sediments enters
