SUBSTANCE: static, dynamic or vibration sensing is carried out preliminary at the selected points to the depth from 1 m with respect to the top of the earth fill. At the same time the samples of compacted soil of undisturbed structure are selected in order to determine the moisture and density of skeleton of the specified soil from several drilled wells at points at a distance of not more than 1 metre in plan from sensing points. Laboratory researches of standard compaction with definition of compacting factor depending on the density of soil skeleton, are carried out on the selected samples of soils from the body of compacted fill. Construction of correlation dependence is performed between the specified values of compaction factor and values of the resistance to penetration of standard cone into the soil during sensing, taking into account determinations previously performed in the laboratory followed by evaluation of compaction quality of the earth fill.

SUBSTANCE: first damages are sealed in hydraulic engineering under water surface by isolation of a damaged section in a hydraulic engineering structure from water access. Sealing is carried out using a sealing cement and sand mortar. The mortar is loaded into elastic water impermeable reservoirs, isolating from access of water and air. Reservoirs are laid from a barge with a grab to the damaged section of the hydraulic engineering structure. Further reservoirs are compacted with the grab grip until complete filling of the damaged section.

SUBSTANCE: device comprises pressure vessels installed into a soil massif and used as setting marks, equipped with sensitive elements for remote measurement of pressure and temperature, a piezometric chamber that rises above pressure vessels and is equipped with a remote level indicator and temperature sensors and a hydraulic line, which hydraulically communicates the piezometric chamber with pressure vessels. Extension in case of hydraulic line stretching does not result in considerable reduction of its cross section area. The end of the hydraulic line opposite to the piezometric chamber is taken out from the soil massif into the area available for liquid drain. The piezometric chamber is filled with liquid to the level exceeding the elevation of installation of pressure vessels by not more than the height h, equal to h=Δperm/Δ, where Δperm - permissible error of detection of height position of a setting mark, mm; Δ - main error of a sensitive element for remote pressure measurement, unit fractions. The method of device operation includes establishment of of vertical positions of pressure vessels laid into the body of the soil massif and used as setting marks. The height position of each pressure vessel is determined using the mathematical error. Hydraulic lines are periodically drained from liquid, and by means of measurement of atmospheric air pressure in pressure vessels, as well as excessive pressure of air pumped into the hydraulic line under pressure close to the rated one for sensitive elements, corrections are determined, which are necessary to produce correct results of measurements of liquid pressure in pressure vessels. After replacement of the liquid in the piezometric chamber and in the hydraulic line until its temperature balances, by measurement of liquid temperature with all sensitive elements for temperature measurement, corrections are determined, which are required to produce the correct results of liquid temperature measurements. After replacement of the liquid in the piezometric chamber and in the hydraulic line until its temperature balances, control detection of pressure vessels height position is carried out, and (or) corrections are determined to calculate the height position of pressure vessels in case of measurements performance under the variable liquid temperature in the piezometric chamber and hydraulic line, i.e. during device operation they periodically calibrate both sensitive elements for measurement of pressure and sensitive elements for measurement of liquid temperature, and the device as a whole.
EFFECT: possibility of uninterrupted automated control of soil massif condition.
