Abstract

Use: erection of bulk earth structures. The embankment is erected in stages, and the rocky draft is formed in layers temporarily broadened. When dumping the last layer, the rocky layer is formed from the rocky soil of the temporarily broadened outline of the previous layers. 5 il.

Description

The invention relates to the field of construction and can be used mainly in the construction of embankments of land structures.

Known methods for the construction of road embankments with anti-deformation berms, including the construction of the embankment with subsequent dumping of the beers of stone material 1.

The disadvantages of the known methods are low berm stability and large labor costs.

There is a method of construction of the embankment, which includes layered soil filling with the layout and compaction of each layer and the sprinkling of slopes with stone material 2.

The disadvantage of the known method of erecting embankments is labor-intensive,

The closest to the proposed technical essence and the achieved result is a method of construction of the embankment, including layering soil dumping

With the planning and compaction of each layer and the sprinkling of slopes with stone material, the embankment is erected from unsorted rocky soil, and after filling each layer, large stones are extracted from it, and the filling is carried out after filling each layer by moving the large stones removed from this layer to its backs parts.

A disadvantage of the known method of erecting embankments is the large labor costs, the non-consolidation of the ridging parts of the earth bed within the design contour of the embankment.

The purpose of the invention is to reduce labor costs and the volume of land works.

This goal is achieved by the fact that according to the method of erecting the embankment, which includes filling the soil with layers, planning, compacting each layer and forming a rocky outline, the embankment is erected in stages, and the rocky outline is formed along VJ

layer temporarily broadened, while the rocky soil sketches are poured after compaction of the first layer with a margin on both its edges, and after dumping the rocky soil, sketches of the second layer are dumped onto the specified layer, after the beginning of dumping the rocky soil, sketches with a margin on both edges begin to dump the second layer, then the operations of filling the following layers are repeated, and when dumping the last layer, the rocky pattern is formed from the rocky soil of a temporarily broadened outline of the previous layers.

Figure 1 shows the placement of machines and mechanisms within the embankment during its construction in accordance with the proposed method; figure 2 - the construction of the mound in axonometry; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 1; figure 5 is a section bb In figure 1.

The proposed method is carried out as follows.

The soil from which the body of the embankment and the rocky soil without the aggregate, with a diameter of 0.35 m, necessary for spraying the embankment, is transported to the place of installation by dump trucks from the quarry or the excavated road excavation, these soils are prefabricated.

The rocky soil of the temporarily broadened outline 1 is filled with dump trucks 2, after compaction of the first layer of the embankment, with a touch on both edges (figure 1, stage I).

Then the second layer is filled (filling the resulting sinus 3 with soil 4 using dump trucks 2 and bulldozer 5 (Fig. 1, stage 1, I) and compacted to the required density standard. After filling and compacting the soils of the second layer, rock sketches are poured with a backlog on both sides of the second layer, then the operations of filling the following layers are repeated until the last layer is filled,

When dumping the last layer of the mound, a rocky draft is formed from the rocky soil of a temporarily broadened outline of the previous layers using a hydraulic excavator - a back shovel 6 (FIG. 1, stage III, FIG. 4 - section BB) in FIG. 1).

If the height of the embankment is 6 m, then (taking into account such technical characteristics of a hydraulic excavator as the maximum reach of the boom and the change in the slope of the slope in height with N b b / 4), the intermediate formation of rock from the temporarily broadened outline of the previous layers should be made the height of the mound Nn 6 m, and the subsequent formation - at Nn 12 m

The dumping of the last layer of the embankment is carried out (Fig. 1, Stage IV, Fig. 5 - section B-B of Fig. 1) according to the technology of construction of the previous layers with further planning and compaction to the required density standard.

The proposed embankment erection method makes it possible to create the necessary thickness of the rocky outline and to combine the work on its adjustment with the layout of the slopes, to achieve the required density of the bordering parts of the embankment. As a result of applying the proposed method, a reduction in the volume of earthworks is achieved due to the construction of a rocky outline within the design outline of the embankment body, a reduction in labor costs due to embankment filling operations with a device on its slopes of stone material.
