Description

The invention relates to the construction, in particular to hydraulic engineering.

There is a known method of storing soil in a pond, which includes marking the area for storing the soil in the pond with boundary signs, for example, landmarks and storing the soil at this site not fenced off from the reservoir 1.

This method is characterized by the following disadvantages.

First, the site for storing the soil is large, as the currents and waves in the reservoir significantly swell the slopes of the soil storage. Secondly, the water body is contaminated with soil suspensions formed during the storage of the soil, as well as during erosion and stabilization of the slopes with currents and waves. All this reduces the effectiveness of the method of storing the soil.

There is also known a method of storing soil in a reservoir, including the erection of a fence on a section of the reservoir in the form of ground dams located along the perimeter of the storage site using freezing 2.

The known method has the following disadvantages.

Firstly, it is difficult to erect a site fencing in a pond, especially in winter, when it is necessary to make slots in the ice around the perimeter of the area, pour ground in them, intended for laying in a fencing, for example, by a truck. This will require work to increase the carrying capacity of the ice cover. Secondly, the risk of work being done by machines and mechanisms near the edge of the slot increases. Thirdly, contamination of the water body with soil suspensions is not excluded both under the influence of the soil fence and when the soil is stored in the enclosed area. All this reduces the effectiveness of the method of storing the soil.

The purpose of the invention is to increase the effect of storing the soil by simplifying the construction of the soil barrier and eliminating the possibility of contaminating the reservoir with soil suspensions when storing the soil.

This goal is achieved in that according to the method of storing the soil in the pond, the fence of the fence is raised to a height greater than the depth of the reservoir at the place of laying the soil, made of filter soil by laying it in layers and freezing it on the ice cover, away from the place of storage, shape and size coinciding with the outline of the land storage area, then cut the ice field along the outer perimeter of the soil fence, form a channel in the pond with the length from the ice field to the place of storage Hovhan notch soil and turf removing ice therein, is transported on ice water channel field with dirt fence to the site soil storage and lowered it to the bottom of the reservoir flooding ice-cold floor.

FIG. 1 shows an ice field with a dirt fence on it, a longitudinal section; in fig. 2 - the same, top view; in fig. 3 - ice field with a dirt fence floating on the canal, longitudinal section; in fig. 4 - small-scale diagram of the channel in the ice cover with the ice field floating in it after trimming the ice field, top view; in fig. 5 - an ice field with a dirt fence, lowered to the bottom of a reservoir in the area set aside in a reservoir for storing soil; in fig. (b) A small-scale channel scheme in the ice cover of a reservoir with an ice field lowered to the bottom of the reservoir in the area designated for the storage of soil.

The proposed method is carried out as follows.

Away from the place where the ground is stored, in a convenient place, for example, in the coastal zone of the reservoir, an ice field 2 is marked on the ice cover 1, the shape and size of which coincides with the outline of the ground storage area. Along the perimeter of the ice floor, earthen dams were erected in layers by layer and freeze of the soil. The dams 3 are raised with a height H exceeding the depth of the reservoir HI at the place of storage of the soil (Figs. 1 and 2). Dams 3 are built from filtering soil, such as gravel-sand. The method of erecting dams can be any, for example, a truck vehicle with a dozer layout and compaction rollers. When dumping dams, they close up the ends of the pull cables 4.

At the end of the construction of dams 3, the ice field 2 is cut along the outer perimeter of the earth dams 3. In the ice cover 1, a channel 5 is formed from the ice field 2 to the place reserved for laying the soil, i.e. from ABEF to EDSD. Channel 5 in the reservoir is formed by cutting ice in the ice cover 1 of the reservoir and removing the cut ice, for example, submerged under ice cover 1. Channel 5 is of such dimensions that the ice field 2 can be freely transported through the channel, which after cutting dips into the water at depth h, since it is loaded by the weight of the dams 3. In fact, after trimming the ice field 2, a floating body is formed, for example, of a barge type consisting of sides, which are made waterproof dams 3 (they are frozen), and bottom role otorrhea performs Noe ice field 2 (FIGS. 3 and 4).

The floating body with the help of tow cables 4 is transported afloat along channel 5 from the ABEF sector to the URDC sector, installed above the place allotted in the reservoir for storing the ground, and lowered to the bottom 6 of the reservoir. Lowering is done by flooding the body. To do this, in the ice field 2, windows are cut out into which water from the reservoir is pushed and fills the cavity formed by the ice field 2 and dams 3. Ice field 2 sits on the bottom 6 of the reservoir (Fig. 5 and 6), and dam 3 elevated above the water level in the pond.

After some time, the dams 3, which are in the water of the reservoir having a positive temperature, are thawed. After defrosting the earth dams 3, the ground 7 is stored in the storage cavity. Warehousing can be carried out in winter by delivering the soil over ice cover 1 or in summer. FIG. 5 and 6 show the storage of the soil in the summer with its delivery by barges 8 and unloading by a grapple device 9 with a bucket 10. When applying the soil 7 to the storage cavity, the water from the warehouse is filtered through

dam 3 and goes into the pond. Suspended soil particles that form when the soil is unloaded into the warehouse cavity remain in the warehouse cavity, since they do not pass through the dams 3 when water is filtered through them into the reservoir. After some time, the ice field will melt 2. Due to its volume, the volume (capacity) of the warehouse will increase.

When using the method, the technology of erection of the ground dams for the site is simplified, since the dumping of soil in them is carried out not under the water, where the current is affected by the ground, but on the surface; the construction of the dams is carried out in a convenient place with good entrances; the safety of work is increased, as dams are erected on a solid, continuous ice cover, and not into a slot in the ice; contamination of the reservoir with soil mist is eliminated, as water from the warehouse goes into the reservoir of sediment when filtered through the soil dams; the season is extended, since it is advantageous to make a dirt fence in winter and soil storage in summer.
