SU1254109A1 - Arrangement for flushing drainage wells - Google Patents

Description

The invention relates to the mechanization of land reclamation and can be used in the hydro-mechanized removal of sediment from the drainage structures and drainage wells on reclamation systems with closed drainage.

The purpose of the invention is to increase the efficiency of sediment removal and reduce water consumption during erosion.

FIG. 1 shows schematically the device, a general view; in fig. 2 - washed away, and the head on the collector.

The device consists of a node 1, fixing the volume. And the soil, made in the form of two coaxially arranged tubes, equipped with nozzles 2, placed in their lower end around the perimeter of the fixing unit 1. In the lower part of the fixation unit, a rubber seal 3 is installed at the end of the outer pipe, which simultaneously serves to seal the internal cavity of the fixation unit and protect the nozzles 2.

Inside the fixation unit 1, a collector 5 with scour heads 6 is placed with the possibility of vertical movement. The collector 5 is fixed on the water-injection pipe 7 with the possibility of rotation around a vertical axis. Water pipe 7 is installed with the possibility of vertical movement together with the manifold 5 and heads 6.

Blurry heads 6 are located at the same angle to the vertical, which ensures rotation of the collector 5 around its vertical axis. A disk 8 equal to the diameter of the collector 5 is rigidly fixed above the collector 5. To fix the fixing unit 1 when it is lowered to the bottom of the well 4, removable clamps 9 are installed in the upper part of the well 4. To remove the slurry from the fixing unit 1 of the soil volume in it a pulp-removal pipeline 10 is brought out of the well 4. In the gap between the coaxially arranged pipes of the fixing unit 1, water is supplied through the water supply line 11. In the lower part of the fixing unit 1, the stop stroke 12 of the collector 5 is located.

The soil volume fixing unit 1, together with the collector 5 placed therein, is lowered into the drainage well until it comes in contact with alluvial skimmers, and then turn on the water supply through the water supply pipe 11 to the soil volume fixing unit 1. Along the gap between the coaxially arranged pipes of the fixing unit 1, water flows to the nozzles 2 located in its lower end. The soil is eroded around the perimeter of the fixation unit 1, an annular slot is formed, along which the fixation unit 1 is lowered into the sediment until the rubber seal 3 rests against the bottom of the well 4. The rubber seal seals the internal cavity of the fixture of the soil volume. At the same time, the collector 5 with erosion heads 6, held by the sediment, remains in the upper part of the internal cavity of the fixing unit 1. After that, the water supply is disconnected through the supply pipe 11 and the quick fixing clamps 9 secure the soil volume fixing unit 1 in the well 4. Then the water supply to the water injection pipe 7 is connected. Water under pressure flows through the collector 5 to the erosion heads 6.

Due to the fact that the scouring heads 6 are set at an angle to the vertical, the collector 5 with the heads 6 begins to rotate, to intensify the erosion of sediment. The pulp is discharged through the pulping pipeline 10. Ground particles falling out of the pulp are deposited on disk 8. The sediment erosion and downward movement of the water-injection pipe 7 with collector 5 and scour nozzles 6 will continue until collector 5 rests into the stopper 12 stroke, located at the bottom of the node 1 fixation.

After that, remove the clamp 9 and remove the device from the well. The limiter 12 is removed from the stroke, the collector 5 is lowered with a disk 8 and the latter is cleaned of sediment deposited. The device is then reassembled and transferred to a new well, where the cycle of operation is repeated.
