Description

The useful model belongs to hydrotechnical construction and can be used in the construction of dams from soil materials in the conditions of reservoirs by pouring soil into water.

There is a known method of building a dam from soil materials in a reservoir, which includes pouring the soil of the dam body into the water, with the arrangement in the central zone of the dam from the upper and lower anti-filtration curtains, in which the lower part is attached to the bottom of the reservoir with the help of a loader, and their upper parts attached to the device in the form of a floating compartment with floating pontoons anchored by cables with a loader at the bottom of the reservoir, with the formation of an internal cavity between the curtains, with the pouring of various soils in parallel into the internal cavity between the curtains and the side zones of the dam and arrangement from the top of the poured dam in the soil of the inner the cavity of the anti-filtration curtain with a monolithizing solution, with the implementation in the coastal zone of floating compartments with sheets of films, which are transported by floating method to the installation site with adjacency and fastening to the previous floating compartment, its separation as a previous compartment (see patent OA Mo 119504 dated 25.06.2019 .|.

The disadvantage of this method is significant complexity with the need to make floating compartments with floating pontoons with film sheets in the coastal zone, their transportation by floating method to the installation site, with adjacency and fastening to the previous floating compartment, its detachment and detachment of the film sheets to the bottom of the reservoir, the need to ensure stability of this system when the dam is dumped under the influence of waves, difficult conditions of work with fixing the compartments of the panels to the bottom of the reservoir and between each other.

The basis of a useful model is the task of simplifying the conditions of work production.

The task is solved by the fact that in the method of constructing a dam from earth materials in a reservoir, which includes dumping the soil of the dam body into the reservoir with an arrangement in the central area of the dam using pontoons located along the axis of the dam with vertical fencing elements of the internal cavity attached to them, with dumping with of the assembled part of the dam parallel to various soils with an advance into the inner cavity and into the side zones of the dam, with the arrangement of the backfill dam in the soil of the central zone of the anti-filtration curtain with a monolithizing solution, according to a useful model, on the slope in the central zone of the assembled part of the dam along the contour of the central zone, set with by dipping into the slope, a trough-like metal rigid structure with side fences

With vertical walls, an open top, bottom and side slope with laying, like laying a slope in the central zone, which is rigidly fixed to the pontoons located above it in the water, connected to the ship, with dumping from the erected part of the dam with advance of the soil into the inner cavity of the trough-like structure and parallel to the fallout from both sides of the soil of the lateral areas of the dam, after filling the internal cavity with soil with the help of a vessel, the pontoons together with the trough-like structure are moved along the axis of the dam for a length so that the trough-like structure remains partially immersed in the slope of the dumped part of the dam, and then the process repeated

In addition, it is possible to pour soil into the inner cavity using a conveyor mounted on a metal structure connected to the top of the trough-like structure.

Due to the installation on the slope in the central zone of the raised part of the dam along the contour of the central zone from a trough-shaped metal rigid structure with lateral enclosing vertical walls immersed in the slope and thus fixed in the raised part of the dam, open above, below and on the side of the slope with laying, as laying slope in the central zone, which is rigidly fixed to the pontoons located above it in the water, connected to the ship, with the fallout from the erected part of the dam by the advance of the soil into the inner cavity of the trough-like structure and parallel fallout from both sides of the soil of the lateral zones of the dam, with the movement after filling the inner cavity with soil using a pontoon vessel together with a trough-like structure along the axis of the dam for a given length so that the trough-like structure remains partially immersed in the slope of the backfill part of the dam, and thus is fixed on the slope with further repetition, in general, provides a significant simplification the mind in the performance of works on the construction of a dam in the reservoir.

Further simplification of the production conditions is achieved by the fact that soil is poured into the inner cavity using a conveyor installed on a metal structure, which is connected to the top of the trough-like structure and moves along with it.

A useful model is explained by the drawing, where: in Fig. 1 shows a longitudinal section A-A along the axis of the dam in the process of its filling after filling the internal cavity, in Fig. 2 - longitudinal section B-B along the axis of the dam after moving the pontoons together with the trough-like structure to a given length,

in Fig. C - a horizontal section B-B along the dam after filling the internal cavity, in Fig. 4 - horizontal cross-section GG along the dam before filling the internal cavity, in Fig. 5 - cross section DD along the dam in the process of its backfilling.

The method of constructing a dam from soil materials in a reservoir With the dumping of soil from the body of the dam into the water with the arrangement in the central area of the dam using pontoons located along the axis of the dam with the vertical elements enclosing the internal cavity attached to them, with the dumping of different soils from the dumped part of the dam in parallel with an advance in internal cavity and in the side zones of the dam, with the arrangement of the backfilled dam from above in the soil of the internal cavity of the anti-filtration curtain with a monolithizing solution, includes the installation on the slope 1 in the central zone 2 of the reduced part of the dam along the contour C of the central zone with immersion in the slope 1 of a trough-like metal structure 4 with by the lateral enclosing vertical walls, open from above, below and from the side of the slope with laying, as the laying of the slope 1 in the central zone, which is rigidly fixed by ties 5 to the pontoons 6 located above it in the water, connected to the vessel 7, with backfilling with advance soil in the internal cavity the bottom 8 of the trough-like structure 4 and parallel to the dumping of soil from the lateral zones 9 of the dam on both sides, after filling the internal cavity 8 with soil using the vessel 7, the pontoon 6 together with the trough-like structure 4 are moved along the axis of the dam for a length so that the trough-like structure 4 remains partially submerged in the slope 1 of the raised part of the dam 3, and then the process is repeated.

In order to further simplify the production conditions, the soil is poured into the inner cavity 8 using a conveyor installed on a metal structure 10, connected to the top of the trough-like structure 4.

Usually, less permeable sand-crushed and gravelly soils are poured into the inner cavity 8, in which an anti-filtration curtain is made from the crest of the backfilled dam using a monopolishing solution, and rock mass is poured into the side zones 9. Pontoons 6 can be made in the form of one pontoon or two rigidly connected pontoons.
