The invention relates to the construction and can be used to create a narrow soil structures by means of hydromechanization,

The purpose of the invention is to improve the performance of hydro-mechanized operations while ensuring the protection of the aquatic environment from contamination.

Figure 1 shows the construction, erected by the proposed method, the plan; Fig. 2 shows a section A-A in Fig. 1 in Fig. 3, a construction, a longitudinal section along the embankment dams outside. figure 4 - the same, with the last step nam.

The design of a narrow-profile alluvial construction includes a quarry 1, located at the head of the settling pond 2, a dam 3 of leaching of the embankment maps with the spillway device 4.

To ensure the implementation of the proposed method of washing, a dredger 5, floating slurry pipeline 6, with shut-off valves 7 and a hanging pipe 8 with a cable-stayed support 9 mounted on the auxiliary pontoon 10, auxiliary floating means 11, floating obstacle 12 and anchor 13 are used. .

Quarry development) The dredger 5, which is developed, is used to extract the soil and create the necessary capacity to form a settling pond 2 in its Waste part.

The settling pond 2 serves for the deposition of fine particles of Gerunt and at the same time is a transport artery for moving the floating slurry pipeline 6, the auxiliary pontoon 10 with the hinged pipe 8 and the floating obstruction 12 along the alluvium maps. In addition, a settling pond 2 serves as a drain for a narrow-profile structure, greatly improving the conditions for preparatory work on the namgau (erection of embankments, installing spillway devices), as well as the conditions for consolidating the stored soil.

The embankment dam 3 ensures the retention of washed soil in the body of the structure and is a mobile formwork made in

the form; solid rectangular-shaped shields, tightly connected by ends with each other.

The discharge device 4 is a section of pipe with a valve at the end, laid across the embankment 3 and with an outlet located in the settling pond 2. At the same time, it serves to drain the waste water from the alluvium map. On each map, two spillways 4 are installed at its opposite ends at different altitude levels (Fig. 3 and 4). At the same time, the discharging device 4 farthest from the quarry mine is installed at a higher level, and the closest one - at a lower level. This ensures the uniform deposition of soil on the map when it is injected into the casing body and prevents the dam adjacent to the outlet device 4 from smudging, and also ensures the creation of low flow rates of slurry flow on the slope of the cushion map, which increases the clarification of the wastewater.

Floating slurry piping 6 is a separate pipe, laid on pontoons and interconnected by a ball lock (type of pipe connection).

The shut-off valve 7 performs the functions of the valve and serves to switch the pulp output from the alluvium card into the tail section of the floating slurry line 6. For example, in the case when the dredge passes a clay lens with no sand friction, such slurry is passed through the floating slurry pipeline 6 and released not on the map of alluvium, but in the tail part of the settling pond 2.

The hinged nozzle 8 with the cable-stayed support 9 mounted on the auxiliary pontoon 10 is a curved section of an L-shaped pipe connected by cables to the support stand located on the auxiliary pontoon 10. The hanging nozzle 8 serves to feed the slurry to the soap card directly from the floating slurry pipeline 6 through the barrier dam 3.

The cable post 9 is vertical; then the rack rigidly connected at the base with the middle of the auxiliary pontoon 10. Upper

The end part of the support 9 has a hinged connection with a hanging nozzle 8. For a more stable position, the support post is connected by cable wires (cables) to the edges of the auxiliary pontoon 10, to the edges of the pontoons of the floating slurry pipeline 6 and to the anchors fixed in the coastal slopes of the ostrich pond 2

The auxiliary pontoon 10 serves to support the cable support 9 and the hinged fitting 8 on the surface of the settling pond 2.

The auxiliary craft 11 - tug provides for the movement of the floating slurry pipeline 6 and the floating barrier 12 along the settling pond 2 simultaneously with the movement of the dredger 5, which allows us to carry on a non-stop structure. Auxiliary craft 11 is also used as a transport for moving mobile formwork - wooden shields of the dike 3 along the construction route from previously washed maps to the newly developed areas.

Floating barrier 12 is a seine, made in the form of a panel of high-strength artificial material, which allows to protect part of the settling pond 2 along the structure’s route from surface to bottom. The material of the cloth allows water to pass through, but it prevents the passage of fine particles of ground in water. One end of such a cloth is fixed along the entire length with floats near the surface of the settling pond 2, and the other end is equipped with weights fixed as well as the floats equal to the distance from each other along the entire length of the cloth and lies at the bottom. The purpose of the floating barrier 12 is to ensure that the entire area of the settling pond 2 is used to lighten the waste waters of the charcoal cards, as well as to create favorable conditions for uniform sedimentation of the suspension along the entire length of the pond-stopper 2 and to prevent the formation of traffic jams from the deposited soil that impede the movement of the floating pulp line 6 and auxiliary floating craft 11.

The method is carried out in the following manner.

Initially, they form a quarry mine 1, in the spent part of which a settling pond is arranged

with 2 along the longitudinal profile of the structure. The soil extracted from the quarry 1 is used to make the initial dams 3 embankment of the alluvium maps. Further, when

In the development of open pit mine 1, all the soil is used for the washing of the structure, and the embankments of the embankment 3 are arranged from a series of wooden shields.

15 At the same time, at least three maps are being rolled along the route, one of which must be under the map, and the other two carry out preparatory work (installation of spillway devices, uprooting stumps, etc.).

At the beginning and at the end of each card, water discharge devices 4 are arranged at different levels with releases,

25 directed to the settling pond 2.d;

Then, installation is carried out in the settling pond 2 of the floating slurry pipeline 6 with a hanging pipe 8 installed on the auxiliary pontoon

30 10, and connect it to the dredger house 5. On the hinged nozzle 8 and in the tail part of the floating slurry pipeline 6, installation of shut-off valves 7 is performed.

Next, in the settling pond 2, along the structure profile, a floating barrier 12 is installed, unwinding it from the spool-drum located on the auxiliary floating craft 11. The floating barrier 12 has

JQ in a vertical plane from the surface to the bottom of the settling pond. The end edge of the floating barrier 12 in the head part of the settling pond 2 is secured at the edge of the quarry development 1 adjacent to the reclamation map, anchors 13. This prevents insufficient rectified clarified wastewater of the reclamation map directly into the quarry development 1 and ensures efficient use

the total area of the settling pond 2.

At the end of the preparatory installation work, the development, hydro-transmission, and the filling of the soil into the body of a narrow-profile structure are carried out. Our soil starts from the far from the mine development of map 1, and as it is filled with soil, it goes to the next map that is close to the mining mine 1.

The pulp flow from the alluvium card enters through the spillway 4 into the fenced part of the settling pond 2 and is directed for clarifying IB to its tail part, goes around the free end of the floating barrier 112, and then moves to the quarry development 1. At the same time pulp flow on an alluvium map, where the velocity of the pulp is significantly higher than in the settling pond 2, is deposited in the soil fraction of the soil, and dust and clay particles suspended in the settling pond 2. The clarified water is reused for I development and gi rotransporta soil coming from the quarry vfabotki jl narrow section into the body structure. The dredger 5 with a floating slurry pipeline 6 and a floating obstacle 12 as it is filled with soil maps is continuously moved in the I pond-settler 2 along the narrow profile route at a speed equal to the development rate of the mine 1. It provides a number of factors that determine the increase in productivity labor and protection of the aquatic environment from pollution.

From the beginning of the map, only one farthest from the release of the spillway device 4, located at a lower level (fig.Z). When the output moves along the route to the middle of the map, on the contrary, the distant spillway device is closed and the spillway is opened at the beginning of the map, located at a higher level (Fig. 4). This achieves a uniform amount of soil on the same surface, more efficient deposition in the body. and prevents erosion of the dike 3 ramping in areas adjacent directly to the spillway device 4.

In the development of a quarry mine for the purpose of in-wash of a narrow structure, soils of various types are used.

granulometric composition, often with a significant content of clay fractions. However, in the presence of such a soil on maps with a relatively short plow (up to 50-60 m long), sand fractions are fully deposited on it, the content of which even in clay soils exceeds 20%, which is quite enough for good washing of such structures.
