Abstract

The invention relates to the field of amelioration and can be applied to collect surface waters from local depressions. The purpose of the invention is to increase reliability by reducing the sediment load in the drainage drain and improving its operating conditions. The device consists of a drainage well 1 connected to a drainage drain 2, a sump 3, closed by a lid 4 with openings 5. The sump 3 by the bottom 6 is mounted on the filtering column 8. The bottom 6 is equipped with a seal 7. The sump 3 includes a filtering water intake pipe 9 consisting of from two telescopic parts with water inlets 10 and a lid 11, with a handle 12. The device also contains pumps 13 and an external settler 14. 1 sludge.

The invention relates to land reclamation, and can be applied to discharge surface waters from local sources.

The purpose of the invention is to increase the reliability of the device by reducing the sediment ingress into the drainage drains and improving the conditions of its operation.

The drawing shows a sub-absorbing device.

The device consists of a drainage well 1 connected to a drainage drain 2, a settling tank 3 with a ribbed lid 4 and openings D it 5, a bottom 1 and 6 seals 7, which is mounted on the filter column 8, the filter unit Ioii 1, 9, consisting of two telescopic parts with supporting holes 10 and a wing 11 with a handle 12. The debris is indicated by the position 13, the outer one from outside is 14.

Water-absorbing device operates as follows.

During wet periods it is superficial. The water enters through the receiving holes 5 of the cover 4 into the settling tank 3, where suspended particles of soil contained in the water precipitate. The purified water through the holes 10 under the bottom 11 of the water intake pipe 9 enters the lower stationary part of this pipe and then into the drainage duct 2. After passing through the flood, the water contained in the pumps through the filter walls of the upper movable part of the water intake pipe 9 located in the sump 3 It enters the lower stationary part of the suction pipe 9 and further into the drainage duct 2, dewatering the sediments in the same way. The water from the external settling tank 14 through the filter column 8 falls into the lower fixed part

water intake pipe 9, located.

under the bottom 6 of the settling tank 3, and through it into the drainage drain 2.

Claims (1)

Before cleaning the sump 3 from sediments 13, the lid 4 of the sump 3 is removed, the upper movable and filtering part of the intake pipe 9 is lowered to the bottom to the level of the bottom 6 of the sump 3, while the water inlets 10 are blocked. After this, the dehydrated sediments 13 are removed by hand or mechanized without any obstacles, since the upper movable part of the intake pipe 9, which is lowered into the lower one, does not interfere with the cleaning. The overlap of the water intakes 10 and the presence of the seal 7 protects the drainage duct 2 from the suspended particles of soil in it during the cleaning of the well, and the implementation of the water intake pipe 9 detachable allows you to adjust the sump capacity. Invention Formula The water absorbing device, which includes a drainage well with a sump and a sump, the upper end of which is provided with a shank and holes, is placed in the sump and crosses its bottom, and the lower one under the bottom of the sump is associated with the drainage pipe that is separate. in order to increase reliability by reducing the ingestion of anos into the drainage drains and improving its operating conditions, the intake pipe is made of two telescopically connected parts, the upper part of which is made with embedding into the lower stationary to the level of the bottom of the settler, while the walls of the water intake pipe are perforated along the entire length and are covered with a filter.
