Description

The invention relates to hydraulic engineering, specifically to a method for erecting groundwater structures in the water, such as lintels and beds,

The aim of the invention is to increase the reliability of work by eliminating the separation of the soil according to the particle size distribution in the process of dumping it into water from a flood position.

FIG. 1 is given a soil bridge (dam) at the time of its dumping, cross section; in fig. 2 - layers of homogeneous soil.

Example 1. Construction of a soil bridge in water 1 (Fig. 1), consisting of rock fill banquet 2, transition layer 3, gravel-clay (crushed-clay) screen 4 and attachment 5 of the upper slope, according to the proposed method carried out as follows.

Initially, the pioneer stone-banquet banquet 2 is poured into water 1 to a height above water level 1, and then the soils of the transitional layer 3 and screen 4 are sequentially poured from the crest of the banquet 2 to its uphill slope into the water The cores are preliminarily and independently of each other wetted and frozen in layers. When this layer 6 (Fig. 2) is placed on the polymer film 7, covered with grease. After that, the soil of layers 6 is developed by mechanisms, forming lumpy soils. The film 7 prevents the freezing of layers 6 between itself and the base 8, thus facilitating the development of frozen soil and increasing the output of lumpy soil.

The soil is immersed in the vehicles 9, delivered to the place of installation and dumped from the vehicle 9 over the upper slope into the water. In this case, larger lumps roll into the base of the soil structure, and smaller structures are deposited in the upper part of the structure. The soil of the transitional layer 3 and the screen 4 under the action of heat of the water of the reservoir melt, forming soil layers of uniform granulometric composition, which, under the action of their own weight and passing through it, are compacted.

Further, in the usual manner, they are laid on the screen 4 of the attachment 5,. under the weight of which, the screen 4 is further compacted and the lintel is layered above the water level 1 to its full height.

Example 2. The erection of a gravel bed for the construction of a bed under water is carried out as follows.

The gravel mix is moistened and frozen in layers. The layers 6 are also separated from each other and the base 8 by a polymer film 7 coated with grease. After that, the gravel mix in layers 6 is developed by mechanisms, in a lumpy form they are loaded onto a vehicle, brought to the place of laying and from a surface position, for example from watercrafts, poured into bed in water. After this soil lumps under water, a bed is made of a material that is uniform in grain size.

Monolithing of soil into lumps can also be carried out through the mechanical development of natural-frozen soil in a quarry, as well as through the development of soil homogenized with gypsum. Under the action of water, as well as the frozen soil, the ground laid under water, monopolized into a clod of gypsum, is monolithic, forming a uniform soil with a granulometric composition.

The invention allows dumping of the soil under water into the elements of the soil structure from the surface position to practically any depth of the reservoir and at high speeds of the water flow without natural stratification. By granulometric composition. This increases the filtration strength and water permeability of the soil structure, and also expands the scope of application of the known method of dumping the soil into the water from the surface position. In this case the contamination of the reservoir with suspended small soil particles will be less than in the known method.

With less efficiency, the method can also be applied during the construction of a structure or its part dry.
