The invention relates to agriculture and can be used in land reclamation.

The purpose of the invention is to accelerate the start of operation of the system in the spring.

Fig. I schematically shows a drainage system, a slit; FIG. 2 shows the mouth of the working branch with the thermal insulation plug installed, a section; Fig. 3 is a diagram of the installation of a jack for removing a plug from a well.

The drainage system contains a conductive channel 1, a collector 2, drainage dehumidifiers 3, a working branch 4 with a backward slope, a washing branch 5, mouth 6, 7, cap 8. Removable plug 9 is installed in the mouth 6 of the working branch 4. rings 10 thermal insulation material, such as fiberglass. Tube length 9 exceeds the depth of soil freezing. The cork 9 is mounted on the rod 11. At the ends of the I1 rod, the disks 12 with sealing cups 13 are fastened, the disks 12 with cuffs 13 serve to protect the cork 9 from getting wet. The rod 11 is provided with a jack 14 to remove the plug from the mouth 6.

The jack 14 comprises a frame 15 with a clamp-on clamp 16 mounted on it equipped with a screw-nut movement actuator 17.

The system works as follows.

Excess moisture from the soil enters the drains 3, then into the collector 2 and further into channel 1. In the usual state, the mouth 7 of the washing branch 5 is closed with a plug 8 and this branch serves as a sump for pumps. Thermal insulating plug 9 is removed from mouth 6. Water outflow from collector 2 into channel 1. occurs through working branch 4. Water movement in this case has a pressure character, which improves drainage and water flow capacity of the drainage, since there is no air entrapment that has a counter-pressure coming in into the water system. In the autumn, before the onset of negative temperatures, the plug 8 is removed from the washing branch 5. Water with increasing speed of movement is discharged through the washing branch 5, while the sediment is brought to the crap 1. After removing the plug 8, the work strap is placed on the rod 11 with the disk 12 fixed at the end with the sealing cuff 13. Then it is put on the rod II of the ring 10 from the thermal insulator material. The rings 10 are compacted to achieve the formation of a sealed heat insulating plug 9. The length of the plug 9 exceeds the depth of soil freezing, which prevents water from freezing behind the plug 9.

At the end of the rod I1, facing the channel 1, the disk 12 is fixed with a sealing lip 13.

With the onset of negative air temperatures, the water entering the mouth 7 freezes, starting from the open end of the wellhead pipe, and gradually forms an ice plug in the mouth 7 that blocks the exit

water from the mouth 7. The water completely fills the collector 2. After that, the drainage stops working.

In the spring, with the onset of positive temperatures, jack 14

remove the plug 9 of the mouth 6.

Removing the plug 9 from the mouth 6 with the jack 14 is as follows.

The bed 15 of the jack is installed on the mouth 6. The clamp bar 16 seizes the end of the rod 11i. Rotating the nut of the actuator 17, move the tong clamp 16, the bar II with the plug 9 in the direction of the mouth 6. At

completely removing the plug 9 from the mouth 6, the end of the rod 11 is released from the grip 16. The plug 9 and the jack 14 are taken to the warehouse.

Water begins to be drained through

mouth 6. Ice on the cork in the mouth 7 is gradually melting. After release, the mouth 7 of the ice plug is closed with a plug 8. Then the system operation cycle repeats.
