The present invention relates to the field of land reclamation and may find application in the construction of drainage, mainly in flooded irrigated land.

There is a method of construction of drainage, including removing vegetative layer, a portion of trenches, laying pipe, backfilling the trench and laying in place of the removed vegetation layers (Ed. St. USSR № 1377328, IPC E 02 In 11/00, 1988).

The disadvantage of this method is the large volume of work associated with the use of complex machines and mechanisms with separate execution of certain operations. Repeated passage of heavy machinery causes compaction of the soil layer on the drained area and, consequently, reduce the yield.

The closest analogue to the proposed method is the method of construction of drainage, including the execution in a single pass of granolithic excerpts channel duchatellier plow canlocate with dumping extracted fertile soil rollers on the edge of the channel and trench excavation working body of granolithic, laying drainage pipes and backfill it with soil, and subsequent movements of the fertile soils in the area of the channel after filling the drainage pipe ground (Ed. St. USSR № 1486562, IPC E 02 In 11/00, 1989).

The implementation of this method avoids multiple passes of heavy equipment is on the area of drained land and reduce the risk of soil compaction. However, the use for the construction of drainage passive scelerata during the formation of cracks by sealing its walls impairs drainage features drainage and allows you to use it only for drainage of surface water, formed by the precipitation of heavy rainfall. In the irrigation zone, where there is a need to capture and divert rising groundwater, this method of construction reduces the effectiveness of the drainage due to the lower permeability of the slit in the sealing wall. In addition, the use in the construction of deep drainage passive scelerata increases the requirements to the strength characteristics of granolithic and increases the intensity of the construction process.

These shortcomings eliminates the proposed method of construction of drainage, including the execution in a single pass of granolithic excerpts channel duchatellier plow canlocate with dumping extracted fertile soil rollers on the edge of the channel and trench excavation working body of granolithic, laying drainage pipes and backfill it with soil, and subsequent movements of the fertile soils in the area of the channel after backfill drainage pipes with soil, in which, according to the invention, before trench excavation produce loosening of the layer of fertile soil along the axis of the stacking drena the Noah trumpet in the band, width not less than the working width of the working body of granolithic, on the edge of the channel to move the loosened fertile soil and the trench excavation produce chain working body reverse rotation ushtrasana of granolithic moving between the walls of the trenches and bunkers of granolithic developed soil, which poured drainage pipe coming into the trench through the guide, while the trench is produced by means of two pairs of dormant dumps that provides consistent styling in her loosened soil and fertile soil.

The technical result from application of the proposed method is that the loosening of the layer of fertile soil and move it to the edge of the channel in combination with the development of the trench chain working body reverse rotation ushtrasana of granolithic with the movement of soil between the walls of the trenches and bunkers of granolithic while laying pipes and the subsequent backfilling of the trench with soil and soil ensures the preservation of fertile soils, the formation of a homogeneous plastic mass of soil, break-out between the walls of the trenches and bunkers and filling volume of the trench behind him, while the first pair of dormant dumps produces movement in the trench part of the ground, stamped on the surface of the hopper granolithic, and the second transporting and puts in a trench loosened fertile soil.

Thus, in one pass of granolithic is laying drainage pipes at great depths while maintaining the filtering capacity of the trench.

The invention is illustrated in the drawing, in which figure 1 shows a General side view of granolithic for the implementation of the proposed method, figure 2 - view of granolithic from above; figure 3 is a General diagram of the complete method, top view; figure 4 is a section a - a in figure 3, the scheme of tilling the fertile soil; figure 5 - section b-B in figure 3, the flow of fertile soil on the edge of the channel; 6 - section b-b In figure 3, the scheme of filling the trench with soil; 7 - section G-g of figure 3, the scheme of filling the trench with topsoil.

Granolithic for the implementation of this method consists of a machine base 1, in the rear part of which is set chain working body 2 reverse rotation, a hopper 3 for covering material, the guides 4 drainage pipe 5. In front of the machine base 1 on a frame 6 mounted additional working bodies: the unit disk knives 7 and crab canadacomputer 8 dumps 9. The frame 6 is associated with the chassis base machine 1 hydraulic cylinder 10. At the rear of the hopper 3 to the frame 11 has two pairs of dormant dumps 12 and 13 with adjustable width.

Implementation of the proposed method with the one described by granolithic proizvodid is in the following sequence.

Before leaving granolithic onto the strip drains installs its working bodies on a given mode of operation. Based on the capacity of the top soil by hydraulic cylinders 10 set the depth of the tillage disc blades 7 and the depth of the passages of the channel plough canlocate 8, adjusting the position of the dump 9 according to the width of the rip strip and the depth of the passages of the channel, set the angle of the falling asleep of the piles 12 and 13, providing the overlapping of the blades 12 of the extrusion zone of the soil and the piles 13 zone forming rollers fertile soil.

In the process of movement of granolithic on the highway laying drains disc knives 7 loosen the strip 14 to a predetermined depth (figure 4, section a-a). Dumps 9 canlocate 8 move the loosened soil at the edge of the channel forming rollers fertile soil 15. Active chain working body 2 granolithic produces the development of a narrow trench during its reverse rotation. This loosened soil from the upper drier layers moves down and mixed with the pulp deep water-saturated layers with the formation of the plastic mass, which is squeezed between the walls of the trench 16 and the hopper 3, closing the drain pipe 5, coming along the guides 4 simultaneously with the filing of the filter sprinkled from the hopper 3. When filling in the trench 16 part of the reservoir is offered by the mass is extruded in the upper part of the trench 16, forming roller 17, unlike the dumps 12 return the soil in the trench 16, and dumps 13 move him fertile soil of the rollers 15 on the edges of the channel.

Thus, the application of the proposed method of construction of drainage can improve its efficiency by eliminating the sealing walls of the trench and to reduce the energy intensity of the construction process.

The method of construction of drainage, including the execution in a single pass of granolithic excerpts channel duchatellier plow canlocate with dumping extracted fertile soil rollers on the edge of the channel and trench excavation working body of granolithic, laying drainage pipes and backfill it with soil, and subsequent movements of the fertile soils in the area of the channel after filling the drainage pipe primer, characterized in that prior to trench excavation produce loosening of the layer of fertile soil along the axis of the laying of drainage pipes in the strip, of a width not less than the working width of the working body of granolithic, on the edge of the channel to move the loosened fertile soil and the trench excavation produce chain working body reverse rotation ushtrasana of granolithic moving between the walls of the trenches and bunkers of granolithic developed soil, which poured drainage pipe coming into the trench through n is sending, the trench is produced by means of two pairs of dormant dumps that provides consistent styling in her loosened soil and fertile soil.
