Description

and wells, increasing separation and reducing hydraulic resistance. For this, the lower part of the unit is made of four hydrocyclones, the drain nozzles (П) 7 of which are hydraulically connected to the suction nozzle 9 of the pump 1. The pulping П 12 hydro cyclone chambers 8 are hydraulically connected to the slurry duct 3. The input П 10 chambers 8 have twisting elements in the form screw surfaces installed in the annular space

The invention relates to construction and water management and is intended for driving cylindrical wells in non-bonded (sand, silt) and bonded (sandy loam, loam, clay) soils, as well as for cleaning blastholes.

The purpose of the invention is to expand the area of the developed soils, increase the productivity of erosion and transportation of the eroded soil, the rate of penetration of wells and wells, increase the separation efficiency and decrease hydraulic resistance.

The hydrocyclone pump unit contains a submersible pump 1 with a discharge pipe 2, forming with hydraulic line 3 a hydraulic elevator 4 with a displacement chamber 5, a cylindrical casing 6 hydraulically connected to the drain pipes 7 hydrocyclone chambers 8 and suction nozzle 9 of pump 1. equipped with twisting elements 11, made in the form of helical surfaces installed in the annular space, formed by the bodies of hydrocyclone chambers 8 and drain pipes 7. Pulp pipes The 12 hydrocyclone chambers 8 are hydraulically connected to a pulp formed by the housings of the chambers 8 and the drain P 7. With the help of a tube 18, the well 19 is poured with water and the unit is turned on. The screw 16, deepened into the ground, washes it by means of a flare by spraying it from the tangential holes 14. In the chambers 8, the fuzzy soil is separated. Sand particles and mechanical inclusions are entrained in the slurry pipe 3. The clarified part is sucked in through P 7 and is injected into the hydraulic loader 4. 4 sludge.

wire 3. In the lower part of the unit, a hollow cone-shaped high-pressure scourer 13 is placed with tangentially formed holes 14 to the outer surface of the scourer 13 along a helical line, where the holes 14 are positioned to supply a scouring fluid from the discharge nozzle 2 through the high-pressure pipe 15. The outside washer 13 is grasped by a screw 16 which is made in a spiral of Archimedes, whose screw line is displaced relative to the helical line of the holes 14. The bottom part of the washer 1 3 has a pointed end 17. The unit has a water supply pipe 18 for soil liquefaction, which is lowered into well 1 9.

Hydrocyclone pump unit operates as follows.

The unit is installed strictly vertically pointed end 17 down and screwed into the ground. Fill the well 19 with water using a tube 18 and include the unit in operation. The screw 16, deepening into the ground, blurs it by means of a flare from the tangential holes 14, which accompanies the rotational movement of the diffuse ground medium along the screw surface of the screw 16 to the inlet ports of the inlet nozzles 10 hydrocyclone chambers 8. In hydrocyclone chambers 8, the blurred soil is separated, sandy particles and mechanical inclusions are carried up into the pulp nozzle and further into the pulp

wire 3. The clarified part is sucked through the drain pipes of 7 hydrocyclones, which are hydraulically connected to the suction pipe 9 of the pump, and is injected into the hydro cell 4. A part of the clarified liquid on the surface returns back through the tube 18 to the well 19 liquefaction of the soil and used as working medium. At the same time, as the penetration proceeds, the well casing is made by the well 19.
