Description

112982972

The invention relates to methods for lamas 12. In the process of filling layer 11

it is compacted and clogged by the line along the line 13.

In the same sequence, the third layer 14 of gravel covering of alluvial structures from local materials such as dams and dams using hydromechanical equipment is deposited.

The purpose of the invention is to increase the reliability of the construction and reduce the construction time.

Fig. 1 shows the scheme of washing up, with a thickness t of 0.2, and its compaction and clogging with irrigation along a strip 15 of width E 4 m. As the soil is washed over onto map 1

In thickness t of 0.2 m, it is compacted and coagulated with polom over a strip 15 with a width of E 4 m.

va structures, top view; 2–10 raise the water level in the pond-section A-A in FIG. 1.

The method is carried out as follows.

Alluvium structures are in layers. Before the washing of each layer, they arrange the embankment of the card due to the dam of the embankment of the lower slope 2, the transverse rollers 3 and the embankment of the upper slope 4,

After the dabbling of the map 1, alluvium is planning a riding slope 4 of the dumping with the laying of a slope of 1: 200 and pouring a layer 5 of gravel covering a depth of 20

7. As a result, a portion of the water containing suspended particles of the soil is filtered through the dam 4 in the lower layer of the gravel covering 5 and clogs it, which favorably affects the quality of the coating.

Thus, during the application of a layer of soil with a thickness of t ,, 1.5 m, a gravel covering of the upper slope of an increased density of 2.0-2.1 t / m with a thickness of 0.6 m is formed, and the time of the gravel covering is 10 days. , and the time of washing of soil on the map for 20 days.

with a tire tj, 0.2 m. At the same time, soil is washed from the distribution sludge line 6. Removal of clarified water from the settling pond 7 is carried out through a discharge well 8. In the process of washing the soil, the gravel covering of the gravel covering with the clarified pulp from the tank is compacted and clogged. 9, produces watering in strips 10 with a width of E 4 m. Water for irrigation and clogging is taken from the settling pond 7, which excludes the delivery of water from the water intake. Simultaneously with the irrigation, the gravel cover is additionally compacted when the tractor passes with the tank 9.

As the coating layer 5 coagulates and compresses, the second layer II is removed by dump trucks 12 with a thickness t ,. 0.2 m with a ledge width of 12 m. Laying of layer I1 leads to a lag of irrigation of the previous layer 5 to the width of the irrigated strip 1 ± 4 M, with this I achieve additional compaction of layer 5 when penetrating an autosink with a thickness t of 0.2 m, compacting and colmating it irrigation along the strip 15 with the width E 4 m. As the soil is washed onto the map 1

raise the water level in the pond

raise the water level in the pond

7. As a result, part of the water containing suspended particles of the soil is filtered through the embankment dam 4 into the lower layer of the gravel surface 5 and clogs it, which has a favorable effect on the quality of the coating.

Thus, during the application of a layer of soil with a thickness of t ,, 1.5 m, a gravel covering of the upper slope of an increased density of 2.0-2.1 t / m with a thickness of 0.6 m is formed, and the time of the gravel covering is 10 days. , and the time of washing of soil on the map for 20 days.

In the sequence indicated, the structure was raised to its full height.
