Description

The invention relates to agriculture and can be used for the reclamation of overwetting lands, taking into account nature conservation requirements.

Water storage systems are known for use in subsurface moistening or irrigation of farmland. The accumulation of water in ponds, including polder land drainage systems, allows water to be supplied by conventional drainage systems and two-tier l.

The disadvantage of such accumulation of water and its subsequent use is that the ponds-reservoirs are separate elements of the SeNfc system that are not combined with other elements, and to create them you need an area and a convenient relief, which is not always the case.

A drainage system is also known, including a collector made of pottery pipes, a porous backfill around it, vertical wells with accumulators, and (pottery tubes 2 are connected).

The disadvantage of this system is the complexity of the design with small tanks for collecting water.

The aim of the invention is to simplify the design and reserve excess drainage outflow for later use.

The goal is achieved by the fact that each drive is made in the form of a trench with a porous backfill, in which pottery tubes are laid in layers, while the lower layer tubes are connected to the well through the holes in it, and the upper layers are rubbed through the crushed stone dust around the well, the income schuyu to the bottom layer.

The reserved drain is then used for irrigation, extinguishing a fire on peat soil, and moistening the upper layer to prevent wind erosion. The trench (straight line or trapezoidal profile; also serves for laying (on porous backfill; pipes of the drainage system, which drains excess drainage outflow in spring and autumn).

FIG. 1 shows the drainage system, general view; FIG. 2 - time 5 cuts A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The drainage system includes vertical wells 1 with a hole 2 in the lower part and crushed stone dusting 3 on its outer side, collectors 4 with drains 5. The storage devices are made in the form of trenches 6 with porous backfill 7, in which pottery tubes 8 and 9 are laid, waste channel 10 to the river 11.

The system works as follows.

During the draining action

Q drainage drainage flow through drains 5 enters the collector 4, and from it into vertical wells 1 and fills them. Through holes 2 in the lower part of vertical well 1 water flows into crushed stone dusting 3. When water accumulates in crushed stone dusting 3 it flows into pottery tubes drives 8 and 9. When filling the tubes 8 and 9 of the porous backfill 7 and the vertical well 0. 1, the excess water is discharged through the collector 4 to the discharge channel 10 and further to the river 11,

With pump irrigation, water is taken from vertical well 1,

5 when emptying it through the opening 2 in the lower part, the water accumulated in tubes 8 and 9 and porous backfill 7, through crushed stone sprinkling 3 begins to flow into the vertical ring 1 according to the principle of communicating vessels.

The invention makes it possible to reserve all the water from light precipitation, if before their precipitation the collectors

5. Are depleted as a result of the intake of water for humidification, thereby preventing the discharge of contaminated drainage flow into the water intake,
