SU914706A1 - Method of erecting counter-filtration elements of dams - Google Patents

Description

The invention relates to the field of construction and can be applied in the construction of soil structures at low temperatures in harsh climatic conditions.

There is a method of erecting progivofiltration elements of dams in harsh climatic conditions by dumping soil into water [1).

The disadvantage of this method is the large energy consumption for the protection of water from freezing.

The closest to the technical essence of the achieved result to the proposed method is the construction of impervious elements of dams, including the preparation of the base, layering of soil and compaction [23.

The disadvantage of this method is the low productivity at low negative temperatures.

Nel inventions - increased productivity.

This goal is achieved by the fact that, according to the method, bulk blocks are produced from the ground by compacting and freezing it, pouring out a melted pad on which bulk blocks are placed, and filling vertical gaps between the blocks with ground paste.

The method is implemented as follows.

Career soils or soils from a winter storage warehouse in a thawed state are transported to molding machines, where the soils in high pressure presses are compacted in the form of bulky blocks, such as cubes, rectangular prisms, etc. On the lateral surfaces of compacted soil blocks form deep protectors and mounting holes. It is recommended to insert reinforcing rods made of rubber, plastic, metal, and other materials, as well as plasticizing agents, into the melted soil mix before it is compacted. Mounting holes are required for loading.

blocks on vehicles and during unloading and laying on maps. Then compacted soil blocks are frozen at negative outdoor temperatures. Frozen volume elements are transported to the construction site.

Before the direct laying of the soil volume blocks on the map, a base is prepared - a cushion of hot-melt soil mixtures with additives of chloride solutions with a thickness of at least 2 cm and leveled them. Then, ground volumetric blocks are placed on the map and the gaps between them are filled with a melt solution of ground mixtures or paste, and the latter are compacted with vibromechanisms. Laying of soil volume elements is carried out by known similar methods as in the construction of brickwork.

Before laying the second row of soil volume elements, their upper surface is cleared of snow and ice with known methods, then 25 soil mixture or paste is poured in and a pillow is made from 2 to 10 cm thick.

The proposed method allows to compact soil volume elements around the clock, regardless of weather conditions.

to fully automate all processes and achieve maximum soil density and work at low temperatures, air.
