SU1213124A1 - Water-absorbing arrangement for amelioration system - Google Patents

Description

The invention relates to amelioration and can be applied in the drainage of heavy, low permeable soils, for diverting surface water from local drainage lands to a closed drainage network.

The purpose of the invention is to simplify the operation of the device, increase the efficiency of sedimentation of suspended particles in the sump and prevent silting of the closed drainage network.

The drawing shows the proposed device, a longitudinal section.

The water-absorbing device consists of a perforated sump well 1 in which a drain pipe 2 is placed, connected to a closed drainage network 3. Above the drain pipe 2, on the bottom of the well 1, a cylinder 4 closed at the top, forming an annular cavity 3 with the drain pipe 2 Cylinder 4 in the lower part is equipped with water intake holes 6. On the overflow pipe 2, a hollow head 7 is mounted for movement along it, provided with holes 8 in the upper part and a seal 9. Solenoid head 7 on the cavity of the overflow pipe 2 siphon tube 10.

The device works as follows.

Water from the surface of the drained closed sink enters the well-settling tank 1 and through the water intake holes 6 into the annular cavity 5. As the water level rises, the hollow tip 7 installed on the drain pipe 2 can move along it d, rest against cylinder cover 4.

When the water level in the annular cavity 5 reaches the level b i

water through the holes 8 fills the cavity of the tip 7, as a result of which it sinks, taking up a position. WITH . As a result, water flows from the annular cavity 5 to the overflow pipe 2 and further to the closed drainage network 3. When water flows through the overflow pipe 2 due to ejection. siphon filling is in progress

tubes 10. The flow of water containing suspended particles of the soil, the passage through the holes 6, changes direction by 180, resulting in centrifugal force

effective sedimentation of suspended particles in sediment 11 occurs.

When the flood declines, when the inflow to the water-absorbing device decreases, the water level in the sump well 1 is set below the cylinder head cover 4, and a vacuum zone is formed under the cover. When water is discharged from the sump 1, an annular siphon is used,

the upstream branch of which is cavity 5, and the downstream branch is the overflow pipe 2. When the water level in the sump 1 falls to mark d, corresponding to the water intake holes 6, air is sucked under the top of the cylinder 4, disrupting the flow of water in the ring siphon. The water from the overflow pipe 2 is discharged into the closed drainage network 3, and the siphon tube 10 ensures that the head cavity 7 is emptied.

As water accumulates in the well-sump 1, the hollow tip 7 mounted on the overflow pipe 2 with the ability to move along it emerges and takes the position a, resting against the cylinder 4. Then the cycle of the water-absorbing device repeats.
