Abstract

The invention relates to water supply, namely to water intake structures. The goal is to reduce the volume of construction work and reduce metal consumption. The water intake structure includes a water intake 1, gravity-flow siphon conduits 2 and 3, a pumping station 4 with submersible pumps installed in tubular wells located in the coastal part 7. The tubular wells are grouped, their axis 8 is oriented parallel to the gravity-flow-siphon conduits 2 and 3 , with each group of tubular wells communicating with a corresponding gravity-siphon conduit through taps 9 and 10 located in the coastal part 7. The end part of each gravity-siphon conduit 2 and 3 is located in the pump station and connected to the tubular wells through a pipe 11 or 12 for charging and breaking the vacuum. The end part of each self-flowing siphon conduit is made in the form of a drainage pipe connected to a vacuum pump 14 and to a pressure pipeline 15, the latter being connected to the drain by means of pipeline 16 with a valve 17. 17 hp installed on it. f-ly, 3 ill.

Phage.1

The invention relates to water supply, in particular to water intake structures, pumping stations of which are equipped with submersible pumps installed in tubular wells located in the coastal part.

The purpose of the invention is to reduce the volume of construction work and reduce metal consumption, as well as increase operational reliability.

FIG. 1 shows a water intake structure, skin, view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The water intake structure includes water injection 1, two self-flowing siphon conduits 2 and 3, pump station 4 with submersible pumps 5 installed in turbine wells 6 located in the coastal part 7.

Tubular wells 6, the number of which depends on a given performance and brand of submersible pumps, are grouped, their axis 8 is oriented parallel to the self-flowing siphon water lines 2 and 3, each group of tubular wells communicating with a corresponding self-flowing siphon water line through taps 9 or 10, located in the coastal part 7. The ring part of each gravity siphon conduit 2 or 3 is placed in the pump station 4 and connected to tubular wells 6 by means of pipe 11 or 12 for charging and stalling kuuma.

The end part of each self-flowing-siphon conduit 2 or 3, placed in the pump station 4, is made in the form of a stand 13 connected to the vacuum pump 14 and the discharge pipe 15, the latter being connected to the stand 13 by means of pipeline 16 valve 17 is installed there. The self-flowing siphon conduits 2 and 3 are charged through the drains 13 when the vacuum pumps are turned on 14. The vacuum pumps 14 turn on and off automatically depending on the water level in the stand. After charging the self-flowing siphon water lines, the water flows

tubular wells 6 and submersible pumps 5 are pumped through the pressure pipe 15 to the consumer. With a vacuum, a wave of water mass oscillations in a self-flowing siphon conduit is formed, which ensures and the water inlet 1 is washed. To enhance the washing, the valve 17, installed on the pipeline 16, is torn off, connected to the pressure pipe 15 by means of the invention. construction of water intake structures for any performance without a substantial increase in the volume of construction and installation works and an increase in the metal intensity of the structure.
