(54) DEVICE FOR LAYING SOIL INTO HYDRO-HANDLES

one

The invention relates to mining, and more specifically to open-cast mining and can be used for laying soil in hydraulic dumps, maps of alluvial sand, as well as in hydraulic engineering during the damming of dams, dams and soil massifs for civil and industrial facilities.

Pulp spill devices are known on alluvium maps consisting of slurry lines, discharge pipes or trays suspended at cantilevers at rails (cables) to ramps and pivotally attached to the slurry line, which are periodically installed (rotated) and fixed in a predetermined position by special turning mechanisms, for example , excavators, winches 1.

The closest in its essence to this technical solution is a device for laying soil into hydrometal; including a slurry line, exhaust pipe with a flexible joint, supporting a gas cylinder with a rotatable platform 2.

A disadvantage of the known constructions is that, in the case of frontal alluvium from stationary or periodically turned exhaust pipes, soil particles are known to disperse over the washed area in accordance with their hydraulic size, i.e. in the area of draining pulp from

The 5 ends (nozzles) of the exhaust pipes, as a rule, coarse fractions immediately fall out, and the smaller classes settle as the pulp flow capacity weakens and the hydraulic slope decreases. Therefore, uneven laying of washed rocks by size, i.e. the modulus of size, for example, sand, within one map of an alluvium varies considerably, which reduces its commercial value. Partially, this disadvantage is eliminated by mixing the rock mash when bulldozing the washed-up cones from under the outlets or washing them out with clean water.

20 At the same time, for a more complete closure of the reservoir of the hydraulic dump (the map of the intakes), the discharge pipes are usually expanded manually or with the help of equipment, which is not always feasible in the conditions of newly reclaimed, unstable soil.

Pulpoids with dispersed releases are usually mounted on racks or piers permanently. The material used for trestles and pillars, as a rule, remains in the washed array without reuse.

The re-laying (moving) of the exhaust pipes is carried out using surface-lifting equipment {cranes, excavators, pipe layers) or other mechanisms, during operation of which oil products reduce the quality of sand, which reduce the quality of the concrete, in the washed soil, for example, commercial sand.

In addition, the rotation of the cantilever suspended exhaust pipes (trays) is not carried out continuously and evenly, but periodically, which also does not meet the conditions of averaged washed soil by size classes, although it reduces this disadvantage to some extent. In addition, the length of the exhaust pipes, cantilevered suspended on the cables, is limited by the height of the supporting racks, their strength and stability.

The purpose of the invention is to increase the efficiency and quality of hydrocladding of rocks in the dumps by averaging the mass modulo the size of the rocks and the uniformity of the pulp spill over the entire area of the hydraulic hole.

The goal is achieved by the fact that the device is equipped with a shunting reversible electric motor 1 with a propeller mounted on the end of the exhaust pipe on which the supporting gas cylinder is rigidly fixed.

FIG. 1 shows a side view of the device; in fig. 2 - the same plan view; in fig. 3 is a section view A of FIG. one; in fig. 4 shows an example of the use of the proposed technical solution for hydrocasting sand on an alluvium map; in fig. 5 - the same, side view.

The device for laying the soil in the hydraulic tails (alluvium card) consists of a gas-filled balloon-suspension 1, an exhaust pipe 2, detachable fasteners 3, a shunting reversing electric motor 4 with a propeller (propeller) 5, an assembly platform 6 with crimping clamps 7, a gas supply slot gas hose 8, gas-pressure fittings 9, flexible joint 10 with flange connection, stabilizer fins 11, main slurry line 12, distribution manifold 13, wiring slurry line 14, alluvium (dump) card 15, dumping embankment 16, treadmill olodtsa 17 spillway pipe 8, collecting the drainage ditch 19, the removable maneuvering stretch rods 20, electrical cable winches 21 and a high pressure gas cylinder 22 with reduction gear.

A gas-filled suspension cylinder, made of a lightweight gas-tight material, is provided with gas-tight fittings 9 and a gas supply hose 8 and serves to support and move through the air the exhaust pipe 2 to which it is attached with rigidly detachable fasteners 8. The exhaust pipe 2, is in common with by the end of the separating slurry line 14 by means of a flexible joint 10, which should be light elastic and ensure the free rotation of the exhaust pipe in both directions to the extreme positions given

angle, for example 90 °.

Standard corrugated sleeves and rubber-fabric hoses are most appropriate for these requirements.

Shunting (reversive) electric motor 4 with a propeller (propulsion)

5 is also a standard product, selected depending on the size, weight, speed of turn and sail of the proposed device.

The motor is mounted on

assembly site 6, which is attached to the discharge pipe by crimping clamps 7.

Rib stabilizers 11 gas cylinder-suspension 1 is made integral with its shell. Their cavities communicate with the cavity of the gas cylinder-suspension and fill

the same gas.

The gas in the gas cylinder-suspension is fed through the high-pressure hose 8 through the reducer from the gas cylinder 22 and (as required) is periodically compensated for

leakage, thereby maintaining the necessary pressure and lift in the gas cylinder suspension.

Removable shunting straps 20 are fastened at one end to assembly site 6, and the others are wound onto the drums of electric cable winches 21 and serve to hold and fix the outlet pipe 2 from arbitrary rotations of the device (when the electric motor is disconnected) when the card is flushed ( hydraulic dump) or in case of strong wind loads.

For example, a helium-Beaudorine mixture can serve as a gas filler for a suspension cylinder 1.

The exhaust pipe 2 is preferably made of lightweight and durable materials, for example, wood plywood or plastic, and coated inside with an anti-abrasive composition, for example, rubber or a mixture of cement and liquid glass or; Finally, insert inside its replaceable sleeves of wear-resistant material.

The device works as follows. Through the main slurry line 12 through the distribution manifold 13, the ground-water mixture is directed to the diverting slurry line 14, then enters the discharge pipe 2 and is then drained onto an alluvium map (hydraulic dump) 15. The exhaust pipe S, supported in air by a gas suspension cylinder 1 and attached ( using the flexible joint 10) to the end of the diverting slurry pipe 14, by means of a shunting (reversing) electric motor 4 with an air screw 5, it rotates uniformly in both directions from the center line of the alluvium map (hydraulic dump) to a predetermined finish by, e.g., 70-90 °, and - at a constant speed.

In this case, the pulp is poured over the entire width of the winding area (along the turning radius of the exhaust pipe) from one side of the alluvium card to the other, the soil from the pulp settles evenly over the washed area, and the water is forcedly held by the dams 16 to drain off the limits of the washed massif with the help of the discharge pipes 18 and the collecting drainage ditch 19.

The supply of pulp to the map of the alluvium (hydraulic dump) is continued until the soil under the exhaust pipe 2 touches it and prevents the turns of the proposed construction.

Then, the pulp is temporarily switched to another card or stops its flow altogether, after which the outlet pipe 2 of the proposed device is disconnected together with the flexible joint 10, the distributing slurry line 14 (to the required length) is increased by inserting a tube of the same diameter, and to the free end of it An exhaust pipe 2 with a flexible joint 10 is attached, and then the pulp feed and hydrodischarge of the soil are again continued by a similar method. And so it repeats until the entire capacity of the alluvium map (hydraulic dump) is filled with the soil of demarcation marks over the entire area of the alluvium.

In general, the technological picture of the hydraulic laying of the soil with the help of the proposed device resembles, as it were, papillating the dredger in the pit with advancing (walking) along the work front.

The technical and economic advantages of the invention are that it eliminates the need to engage in earth-moving equipment, such as bulldozers, with the help of which, as a rule, dig up and push the cone, which is usually formed quickly under the discharge pipe (at the front

concentrated reclamation) and preventing the further process of the hydraulic laying of the soil.

When hydrosposing, for example, commercial sand, this device allows it to be averaged over fractions, i.e., to achieve maximum homogeneity and stability of the modulus of particle size of the washed product over the entire card volume (hydraulic dump), and therefore makes it possible to significantly improve the quality of the stored construction mafapala.

With the help of the proposed technical solution (by shifting and increasing the diluting slurry line, as well as papilioning (turns) over the washed area), the efficiency of using the volume of the flush card is increased by 35-40%, which allows storing significantly more marketable goods on the same area. sand and contributes to a more compact laying rocks in cramped conditions.

In addition, with the use of this technical solution, the downtime of the reclamation card (hydraulic dumps) in auxiliary operations, for example, on cleaning the cones from under the end of the exhaust pipe, as well as on the spreading of the separating slurry line will be almost halved.
