Description

The invention relates to land reclamation and can be used to regulate the air-water regime of waterlogged soils.

Known drainage and moisturizing. a system including drains, drainage collectors, a distribution channel and a transporting collector, while the mouths and sources of drainage collectors, as well as a distribution channel, are equipped with locks £ 1] <

The disadvantages of this system include the manual transfer of the system from the dehumidification mode to the humidification mode and vice versa, and the unevenness of the area moistening due to the presence of trapped air in the drain sources.

Also known drainage and humidification system, including drains, collectors and a water intake [2],

The disadvantage of this system is the low reliability of its operation.

The purpose of the invention is to increase the reliability of the system by removing air plugs from it that • formed when water was supplied to the drains for humidification.

⁵ The goal is achieved by the fact that the sources of drains are combined by aeration collectors connected by means of crosses bent Π-shaped in the vertical plane, located above the maximum water level in the drainage network and below the depth of tillage.

In FIG. 1 shows a planned ¹⁵ location of the drainage and humidification system} in Fig. ' 2 is a section AA in FIG. 1 'in FIG. 3 .- section BB in FIG. one.

_{20 The} proposed system consists of drains 1, drainage manifolds 2, well 3 of a transporting closed collector 4 and channel 5. For the removal of air plugs, the system is equipped with aeration collectors 6, which combine the sources of drains 1. Aeration collectors 6 are interconnected by crosses 7 made of two plastic tubes bent U-shaped in a vertical plane. The well 3 is made of prefabricated reinforced concrete elements 8 and is divided by horizontal overlap 9 into two floors, in the lower of which a diaphragm hydraulic machine 10 is installed, which regulates the drainage drain hydraulically connected to the second floor by the pipe 11. In addition, the inputs of the transport collector 4 are built into the lower floor of the well and drainage collector 2, and the mouths of drainage collectors 2 are connected to the upper floor by a bulk pipe.

The system operates as follows.

In the presence of excess moisture, it works as a drainage network. Drains 1, drainage collectors 2, aeration collectors 6 collect groundwater in the lower floor of well 3, from which they are discharged through a transporting collector and discharged outside the drained territory. At the same time, the hydraulic machine does not impede the flow of drainage water to the lower floor of the well 3. The surface water during drainage is collected by the humidification channel 5 and is also diverted outside the system.

When moistened, water from the drainage collectors 2 enters the drains 1

968161 4 against their slope from the side of the mouth, which usually leads to the formation of air jams that collect in aeration manifolds 6 and discharge 5 into neighboring drainage areas not yet filled with water using crosspieces 7 and move on until they leave the system.

The use of the dehumidification and humidification system of the proposed design will eliminate the formation of air jams in drains.

Claims (2)

The invention relates to amelioration and can be used to regulate the water-air regime of over-wetted soils. A drainage-humidification system is known, a system including drains, drainage collectors, a distribution channel and a transporting collector, while the mouth and sources of drainage collectors, as well as the distribution channel, are equipped with gateways. The disadvantages of this system are manual conversion of the system from the drying mode 8 and vice versa, and the uneven wetness of the area due to the presence of trapped Air in the sources of drains. A drainage and humidification system is also known, including drains, collectors and a water intake 2. The disadvantage of this system lies in the low reliability of its operation. The purpose of the invention is to increase the reliability of the system by removing from it air plugs formed when water is supplied to the drains for humidification. This goal is achieved by the fact that the sources of drains are connected by aeration collectors connected to each other through U-shaped curved crosses in the vertical plane located above the maximum water level in the drainage network and below the tillage depth. FIG. 1 shows the planned location of the drainage and humidification system) in FIG. 2 shows section A-A in FIG. 1, in FIG. 3, section bb of FIG. 1. The proposed system consists of drains 1, drainage collectors 2, a well 3 transporting its closed collector k and channel 5. To drain air plugs, the system is equipped with aeration collectors 6 which combine the sources of drains 1, Aeration collectors 6 are interconnected with crosses 7, made from two plastic tubes bent U-shaped in the vertical plane. The well 3 is made of precast concrete elements 8 and is divided by horizontal overlapping 9 into two floors, in the lower of which a diaphragm hydraulic automat 10 is installed, which controls the drainage drainage hydraulically connected to the second floor 11. In addition, the inputs 12 are built in the lower floor of the well 3. transportation (the collecting manifold k and the drainage collector 2j and the mouth of the drainage collectors 2 are connected to the upper floor by the filling nozzle. The system works as follows. In the presence of excessive moistening, it works as dry Drainage network 1, drainage collectors 2, aeration collectors 6 collect groundwater in the lower floor of well 3, from which it is diverted to a lower collector and discharged outside the drainage area. The hydraulic unit does not prevent the drainage water from entering the lower the well floor 3. The surface waters are collected during the drainage by the humidification channel 5 and are also drained outside the system.When the water is moistened, the drainage collectors 2 enter the drains 1 14 against their slope from the mouth, which leads to usually forming air plugs that are collected in the aeration collectors 6 and diverted to adjacent drainage areas that are not yet filled with water with the help of crosses 7 and continue to move beyond the system. The flpMMeHeHHe of the steam-humidification system of the proposed design will allow the formation of air congestion in drains to be excluded.
