FIELD: construction. ^ SUBSTANCE: device for separation of concrete item parts comprises a container, where excessive pressure is pulled with the help of gas generated as a result of chemical interaction between a chemical compound and an aqueous solution after the preset delay. The container holds the aqueous solution and is attached to the vessel containing the first cavity for storage of a chemical compound in it and a burst disc arranged between the first cavity and the container to ensure complete tightness between a chemical compound and an aqueous solution. The vessel comprises the second cavity, where the following is installed: an electronic trigger, an actuator, which is controlled by means of the trigger to explode the burst disc upon the preset disc, which results in the specified chemical interaction inside the container. ^ EFFECT: provision of controlled and reliable start of chemical interaction irrespective of limitations related to environment suitable for any concrete items and simple to use. ^ 10 cl, 6 dwg |
