Abstract

A METHOD FOR FORMING WATER FROM AQUEOUS WATER ON MARYAH, consisting of cutting a trapezoidal trench and strengthening its surface by dumping it into a transport trench. means of rocky soil and the formation of a surface layer of the ditch from it, characterized in that, in order to reduce the laboriousness of the work, the soil is dumped along the length of the trench portions in a total volume equal to the volume of the surface layer of the ditch, which is formed by leveling along the bottom trenching with a bulldozer blade with a nozzle of portions of dumping soil and subsequent distribution by a waste profiler of a part of this soil on the slopes of the trench.

Description

The image refers to land reclamation construction and can be used in the formation of drainage ditches. The closest to the present invention is a method with weapons of drainage ditches on marks with cutting a trapezoidal trench, filling it with a rocky gravel-pebble soil and a secondary excavation of a portion of this soil from the central section of the section, leaving a layer of reinforcement at the bottom and slopes fl. The disadvantage of this method is the great complexity of the work. The purpose of the invention is to reduce labor costs. The goal is achieved by the fact that, according to the method of forming drainage ditches on the stamps, consisting of cutting a trapezoidal trench and reinforcing its surface by pulling rock into the trench and forming a surface layer of the ditch, the extraction of the soil takes place trenches in portions in a total volume equal to the volume of the surface layer of the ditch, which is formed by leveling grasses / lei on the bottom of the grass / lei with dozer slug with a nozzle in portions filled with soil and then On the distribution side of the profiler dumping soil on the slopes of the trench. FIG. 1 shows a ditching, side view; in fig. 2 shows section A-A in FIG. 1 -, in FIG. 3 - filling of a ditch with rocky soil, type of boom; in fig. 4 shows a section BB in FIG. in fig. 5 - leveling of rocky soil in a ditch side view} in FIG. 6 - section B-B in FIG. five; in fig. 7 - redistribution of the cliff Soil, side view; in fig. 8 - section G-Y in FIG. 7J in FIG. 9 is a view D of FIG. 7; in fig. 10 - section EE & FIG. 9. The method is carried out as follows. Peat excavator 1 on a track terrain with a profile bucket is cut in the summer, when the permafrost layer is thawed, drainage ditch 2. Then it is filled in the volume of fortifications using dump trucks in 3 portions rocky soil from the quarry 4. When the bulldozer 5 is moving, they level the ditch 5 with a profile nozzle 6 in the lower part of the blade 7, the soil 4 with a layer 8, the width of which provides for placement of the tractor code. The edge of the blade 7 is located above the edges of the ditch 2. When re-passing, the blade 7 is set to the transport position and cut with the profiler 9 on the ripper tooth 10 the profile of the reinforced ditch in layer 8, the cut soil accumulates in front of the profiler in the form of a prism 11, moves up the plane of the profiler 9 and, due to the spread created by the compacted stone core 12, is squeezed out into the gap between the edge of the profiler 9 and the surface of the upper part of the slope, i.e. continuously redistributed along the profile of ditch 2, forming a surface and bone layer of fortifications 14. With sufficient power of the base tractor, leveling and redistribution of stones along the ditch profile can be performed behind the tractor (use of the invention will reduce the labor intensity of the work.

METHOD FOR FORMING A WATER DRAINAGE DUT ON MARA, consisting of cutting a trapezoidal trench and strengthening its surface by pouring rocky soil into the trench with vehicles and forming a surface layer of the ditch, characterized in that, in order to reduce the laboriousness of work, the soil is sprinkled they are produced along the length of the trench in portions in a total volume equal to the volume of the surface layer of the ditch, which is formed by leveling along the bottom of the trench with a bulldozer blade with a nozzle of a portion of loose soil and after the distribution of the part of this soil on the slopes of the trench with a dump profiler. £ S. b C © KZ (X) σ> 1 1129286 2
