SU28838A1 - Cap for water outlet for surface water discharge into the sea - Google Patents

Description

When the rivers flow into the sea, the force of the river flow is up to the sea. It is necessary to overcome the resistance from the sea, which arises due to the sea surf and the introduction of estuaries by sediment ejected by the sea during a storm. In large rivers, carrying powerful costs, having significant flow rates and fairly deep, well-established channels, water is released into the sea without any particular difficulties, except for the formation of a bar at the mouth of the rivers, thanks to the deposition of nano rocks caused by the flow of these rivers. A completely different picture is obtained when the waters of small rivers or trenches are released into the sea, whose living force is insufficient to overcome the resistance from the sea. In this case, usually the rivers do not have their permanent, firmly fixed mouth at their inflow into the sea, and under the pressure of the sea surf they are forced to turn their current along the coast of the sea, while gradually, by filtration or thanks to randomly favorable local topographical conditions, will find a way out to sea.

Usually from the side of the sea, as a result of sedimentation during storms,

a solid dune is formed, going along the whole coast of the sea, due to which the flow into the sea of water gathering in the territory located beyond this dune is difficult, resulting in the usual waterlogging of localities along the coast of the sea, caused by the absence of the necessary flow of surface water into the sea, and by flooding the terrain with waters of rivers that do not have a permanently secured exit to the sea, and therefore leave their banks.

In order to eliminate these drawbacks to improving the release of water from small rivers and ditches, the proposed drainage head for surface water flow into the sea, made in the form of a box with holes for water release, has the shape of a downwardly curved wedge formed by intersecting ceiling and floor pipes with a semi-tip profile of the seacoast and holes arranged so that water is discharged from it in the directions perpendicular to the direction of the sea surface.

In FIG. 1 shows a longitudinal section of the tip of a water outlet for the discharge of surface water into the sea, in accordance with I-I of FIG. 2;

FIG. 2 is a top view of it; FIG. 3 is a cross-section of it in II-II of FIG. 2

The water to be released into the sea {from a river, canal, swamp, etc.) is fed into the sea by an open canal that cuts through a dune with a notch 8 or, for example, with a tunnel if the height of the dune is large; The free water horizon in the channel is designated 1, then water flows from the canal under pressure to pipe 2, from which it flows into the sea through openings 3,4,5, located on both sides of the tip 11 of pipe 2, made in the form of a box. These openings are located at the sides of the head, so that the streams of discharged water, before leaving them at sea, rotate 90 ° relative to their original direction in pipe 2, the output simultaneously on both sides of the head 11 parallel to the coastline, in order to ensure uninterrupted operation also the periods of pouring the heading And the waters of the surf, since the directions of the velocities of the surf and the waters flowing from the pipe are perpendicular to each other and, therefore, do not counteract each other. The horizon of the water in the sea in a calm state is indicated in the drawing with figure 10. The cap 11 of the water outlet pipe 2 pouring water into the sea is made in the form of a wedge bent downwards, formed by the intersection of the tube 2 at the acute angle of the ceiling and floor 2. Inside the cap 11 Spacer posts 6 were installed to facilitate the work of the ceiling of the pipe, especially when the waves of the sea surf hit. The transverse section of the coast of the sea remains after laying the pipe 2 without any changes, as the open pit for laying the pipe 2 falls back to its previous level 7.

The shape of the floor, the cap 11 of pipe 2, is in its outlines the profile of the cross-section of the sea coast, smoothly approaching and combining with it without the presence of any protrusions and stops that could break and produce a dynamic effect of the sea waves. The proposed cap shape is designed to maintain the existing coastal regime under storms, and sediments ejected by the sea will be deposited on the sea coast above pipe 2, as before, without producing any contamination inside the pipe and preventing the free discharge of water from the pipe sea through the side holes 3, 4 and 5.

For proper stability and connection to the filling, the body of the pipe 2 can have a protruding lower plate on both sides with counterforces 9, as shown schematically in the attached drawing.

The movement of sea sediments along the sea coast occurs mainly in the direction of the prevailing wind, with sea waves of medium strength, while the movement of sediments, in a direction perpendicular to the coastline, occurs under the action of a storm wave of large force, which throws sediments of larger magnitude onto the coast. capturing them from the seabed in places where the oscillatory motion of the rolling waves begins to break, meets with the bottom surface, and as a result turns into a translational motion understanding of great strength and speed.

It is assumed that the movement of sediments along the seacoast line will occur freely, due to the transverse aperture of 3-h3, 4-4, 5-5 located on both sides of the pipe against each other. With regard to sediment discharged by the sea ashore during heavy storms, these sediments should be carried along the top of the pipe and deposited on the coast above the pipe, not completely falling inside it, due to the protection from the action of the marine wedge-shaped cap 11. In this case and the fact that the pipe 2 will operate all the time, release under high pressure water into the sea, washing and carrying with them into the sea those particles of sediment, which are all. will be able to get into her mouth. The high velocity and the flushing capacity of the jet produced by the pipe, of sufficient force for the sediment that accidentally falls into its sphere of action, is determined by the difference in the water levels / channel and 10 in the sea.

The subject matter of the invention.
