Abstract
Device for severing parts of a concrete work, comprising a container in which an over-pressure is generated by a gas produced by a chemical reaction between a chemical compound and an aqueous solution after a predetermined delay. The container includes the aqueous solution and is attached to a case comprising a first recess for storing the chemical compound. A burst disk is arranged between the first recess and the container for ensuring a total sealing between the chemical compound and the aqueous solution. The case includes a second recess enclosing an electronic trigger, an actuator being controlled by the trigger to cause bursting of the burst disk after a predetermined delay, causing said chemical reaction inside the container.
