SU1381237A1 - Arrangement for constructing enclosed horizontal drainage - Google Patents

Abstract

The invention relates to the field of amelioration and can be used in the construction of closed horizontal drainage in flooded lands and collapsible soils in the irrigation zone. The objective of the ebb is to simplify the technology. The device includes a cutting tool mounted on the base machine, made in the form of a U-shaped plowshare, the vertical posts of which are made in the form of hollow pipes 1 and 2. In the lower part of the plowshare there is a cutting head 3. Pipe 1 of the sieve for supplying the drainage pipe 7, and pipe 2 - for supplying filtering material. The pruning head 3 has a cavity for forming a drain pipe in the filter material. When the base machine moves, the pipes 1 and 2 cut the soil layer vertically, and the head 3 cuts the array of soil from below, simultaneously laying the drainage pipes and filtering material. 3 il. & (L

The invention relates to land reclamation and can be used in the construction of closed horizontal I drainage in flowing and overlying soils in the irrigated zone.

The purpose of the invention is to simplify the production technology.

FIG. 1 schematically shows the proposed device, top view; Q in FIG. 2 - the same, side view; in fig. 3 shows section A-A in FIG. 2,

The device for the construction of a logging machine includes a known base machine (for example, BDM-301A, etc.), t5 on which the cutting tool body, made in the form of a U-shaped plowshare having two parallel and inclined mounted hollow arms, is suspended. pipes 1 and 2, the lower ends of which are connected to the undercutting head 3. Drainage pipes are fed to pipe 1, and filtering material (sand-gray mixture) is fed to pipe 2. The pruning head 3 consists of an anterior cutting part 4 and a tail part 5 and has a cavity 6 through which drainage pipes 7 come out with filtering material 8 sprinkled around them. The pipes 1 and 2 in the front part are filled with knives and 9 .

The device works as follows.

On a pre-trench length

At least 2-3 m lower the working body attached to the base machine. The filter is poured into the base machine boot.

and a drum with coiled tubing 7 is installed. Thereafter, the base machine starts moving along the previously planned drain path, while laying down the drain tube. At the same time, pipes 1 and 2 cut the ground layer vertically and parallel with knives 9 of the set width, and head 3 cuts the array from the bottom, while lifting it up due to the shape of the knife 9 and laying the drainage pipes 7 and filtering material 8. Following the head 3, the ground layer descends laid drains.
