Description

The invention relates to land-reclamation construction, mainly to the drainage layers, relates to devices for carrying out filling of drainage gaps in the trenchless method of building closed drainage and can be used in working bodies of drainage layers with filling of the drainage gap by local permeable soil without filtering. A working unit of the plow maker is known, which includes a knife stand with a flat front cutting edge made in the form of a broken line with an expanding upper part, along the edges of which there are two sidewalls fastened with a cross bar to form a bucket without a rear wall. Two gutters are made in the sidewalls, one for feeding a flexible pipe to the bottom of the slot, the other for feeding a sand-gravel filter. During the passage of the slit, the cutting edges of the sidewall work as undercutting knives, cutting the top layer of soil, including turf. Under the action of cutting forces, the soil in front of the knife, along its flat cutting edge, is pushed upward toward the open surface and into the upper bucket part of the knife-rack, and then dropped into the open slot 1. The disadvantage of such a working member is that during its operation the drainage slot is fed by the soil of the subsurface layer, which, when drying the soil of heavy mechanical composition, leads to a significant reduction in the drainage effect of drainage. The closest to the invention is a draining machine tool, including a body and a knife rack mounted on it, a guide for a drainage pipeline and a backfill dryer 2. The disadvantages of this tool are the difficulty of providing a permeable primer to fill the drainage slot due to uneven supply of cut soil to it from permeable layers, clogging up the gap with lumps of soil of large diameter, wedging it between the sides with bristles, as well as the necessity of pei-leveling the height Application of cutting teeth nrisypateley when changing depth Bookmarks drains. The aim of the invention is to increase the quality of the powder regardless of the depth of the drainage without changing the working body. The goal is achieved by the fact that in the working organ of a donor-spreader, comprising a body and a stand with a knife fixed on it, a guide for a drainage pipeline and a rear powder, the powder body is made of side walls that form a vertical guide cavity and have upper stepped edges spaced along height step size steps, and of the cutting teeth attached to the horizontal portions of the stepped edges. In addition, the side walls of the apatelle are made with inclined cuts in the rear lower part. FIG. 1 shows the working body of the granulator, side view; in fig. 2 - the same plan; in fig. 3 - the same, view from behind. The draining machine's working member consists of a body 1 and a stand 2c fixed thereto with a knife 3, a guide for a drainage pipe 4 and a back flap 5. The side walls 7 and 8 of different heights are welded to the back wall of the body 6, which form a vertical guide cavity and have upper step edges 9. Different heights of the right and left walls of the dusting agent on the shaft of the step 9 provide for a more uniform mixing of the loosened lower layers of the soil and permeable soil from the upper layers. Removable cutting teeth 11 are fastened with bolts on horizontal sections of the 10 step EH edges. The side walls 7 and 8 are fastened to each other by a tie 12. In the lower rear part of the side walls, inclined sections 13 are made. The working body works as follows. When the plowing knife moves, the knife 2 with the pillar 3 cuts through the soil, creating a gap in it equal to the width of the pillar. Through the base of the housing 14 along the guide 4, the drainage pipe is laid at the bottom of the slit. The soil is fed to fill the gap through the dusting teeth. Due to the stepped shape of the upper edges of the side walls 7 and 8, the teeth of the extractor 11 are layer-by-layer cutting off the soil on both sides of the drainage slit, provide consistent supply of the cut layers into the cavity of the slit and the bottom of the drainage trench so that the upper, more permeable layers can lie on its bottom . At the same time, the soil from the upper layers of the soil with the most favorable filtration properties is placed on the bottom of the slit directly on the drain, while the deeper layers are loosened by the catch width of the powder, and also mixed with the more permeable soil. The different heights of the side walls 7 and 8 allow more evenly penetrating the gap by the permeation of the soil, and the presence of inclined cuts in the rear lower part of the side walls allows you to avoid soil seizure between the side walls and dragging. As a result, backfilling of the drainage gap acquires filtration properties sufficient to ensure the drainage effect of drainage during its construction in loamy soils. The priming of the soil on the front teeth-knives of the apatelifier, located on the upper steps, is insignificant, on the lower prongs-knives of the apron.

located in its rear part, soil sticking is more pronounced due to the greater plasticity of the soil in layers located at a depth of 3050 cm from the surface of the earth.

The invention is in the recommended range for piling works

soil moisture provides backfilling of drainage shells with local soil from permeable layers by layer-by-layer cutting and even feeding, avoids jamming and dragging the soil between the side walls and simplifies the process of trenchless drainage laying.
