Description

one

The invention relates to hydraulic engineering and land reclamation construction and can be used in the development of large water supply channels.

The purpose of the invention is to reduce labor costs and improve the quality of dumping embankments of channel dams during the development of canal sites with high groundwater levels.

FIG. 1 shows a section of the erected channel, top view, FIG. 2, section A-A in FIG. one.

The method is implemented in the following order.

During the development of the soil, a bulldozer 1 in the upper non-watered rusa 2 across the channel axis arranges trenches-conduits 3. To eliminate significant water losses due to filtration and. fast filling of trench line 1 is performed with a bias towards overhangs 4. Work on the water supply line in the lower water section of the cross section is carried out using needle-filter installations 5. The ground water pumped out of the water layer is fed through pipelines 6 to Go, then, from the water of the Innocent

sheduses 3. After filling them with water, the mole drain humidifiers are cropped by the molehill 7. A high-quality watering and subsequent mixing of the wetted and dry ground is done;

direction, perpendicular to the development of soil in the cross section of the channel. The development of the soil in the cross section of the channel is carried out in a consistently trench manner. The wetted soil of the first Rus is developed by the bulldozer 1 with overruns 4 along the sides of the channel and laying in the canal dams 8. The dried soil of the underruss is developed by the bulldozer 9 under the overhangs 4.

Invention Formula The method of construction of the channel, including cross-sectional development of the section with brute force along the sides of the canal in the upper rus and movement of soil from the lower rus to the surplus by earth-moving machinery. in order to reduce pipe costs and improve the quality of dumping embankments around 25 channel dams when developing canal sites with high groundwater levels, in the upper non-watered river across the canal axis, water trenches are arranged with a slope towards 35 the bottom rusa makes the pumping of groundwater with its supply to the trenches, cut the network of humidifiers and develop the soil, while cutting the humidifiers is carried out. in the direction perpendicular to the excavation of the soil in the channel section. ii VNIIPI Order 3775/26 Circulation 606 Subscription Random polygons pr-tie, Uzhgorod, st.
