Description

The invention relates to land reclamation, namely, drainage and humidification systems.

A well-known drainage-humidifier system is included, including closed drainage and open channels that discharge excess water by gravity or by pumping it out, and humidification is carried out using a pump station,. ~ irrigation system and sprinklers [1].

The disadvantage of this system is the high cost of construction and operation.

Known water control head) 5 including mounted on its inlet and outlet nozzles actuating valves [2].

Its disadvantage is the inability to discharge water during drainage and its reverse supply from the water intake to the collector’s canal for humidification.

The purpose of the invention is the automation of water supply for humidification and its discharge during drainage.

This goal is achieved by the fact that the water control head is equipped with a water well located between the valves and the attachment. 30 with a tee to the outer wall of the well with a two-way valve and spillways introduced into the head after the valves.

In FIG. 1 shows a water control head; in FIG. 2 - two-way tee.

the water control head is installed at the mouth of the open collector and is a reinforced concrete pipe 1 with a bell, 1-2 m in diameter, depending on the value of the estimated water flow in the collector channel. It is equipped with bolts 2 and 3 mounted on its inlet and outlet sockets, automatically opening and closing using electric motors, between which a well 4 for water intake is installed by a mobile pump station using a suction line 5. The head has drainage pipes 6 and 7, between the flanges of which tee 8 is installed, and the opposite sides of the pipes 6 and 7 25 are inserted into the inside of the head through the side holes in the pipe 1 to prevent erosion of the collector channel and the water intake by the water flow discharged into them . For stability, the spillways 6 and 7 and the tee 8 cre3 <1 are against the outer wall of the intake well 4.

The tee 8 is equipped with an automatically adjustable valve 9, the switching of which is carried out using electric motors 10, respectively connected to the electric motors of the valves 2 and 3. When opening the valve 3, the valve 9 automatically opens towards the drain pipe 6, and when the valve 2 is opened, the valve 9 opens to the discharge side pipes 7. A waste-holding grate is installed on both sides of the head 11. The top of the head is installed at the level of the household water level in the water intake for gravity discharge of excess water from the collection channel calving into the water intake and returning it to the collecting channel in the dry period of the year.

Water control head for drainage and humidification system works as follows.

During drainage, excess water from the drainage system enters the open collector channel and, with open valves 2 and 3 of the water control head, flows by gravity into the water intake, the level of which is below the top of the water control head.

During the growing season, when the water level in the water intake is higher than the water level in the collector channel, with open gate valves 2 and 3, water is also supplied by gravity for humidification. If gravity drainage or humidification is not possible due to the high for drainage or low for humidification water level in the water intake, the pump station is included in the movement. In this case, for drainage, the pumping station, with the valve 2 closed and valve 3 open, draws water from the well 4 using the water intake line 5, delivers it through the pump discharge pipe connected to the free flange of the tee 8, and discharges water through the drain pipe 6 to the water inlet, at the same time, the spillway pipe 7 is blocked by valve 9. To moisten the drained area, water from the water intake is supplied to the collector channel by a pump unit with a closed valve 3, an open valve 2, and an open valve 9 for supplying water through the spillway Rub 7 in the collector channel, from which water enters the closed collectors and drains. Automatic control of the water level in the channel collector and soil moisture is carried out using a pumping unit, positional controllers and a float chamber.

The advantage of a water control head for a drainage and humidification system is that with its help, the system works as a gravity drainage and humidification system, as well as with machine water lift. Due to the presence of a water control head, there is no need to build an expensive building for a pumping station. The mobile pumping station can be used to work on another similar system, i.e. Serves 2-3 such sites, as well as for flushing drainage or sprinkling. The drainage drain collected in the collecting channel enriched with nutrients is used for irrigation.
