摘要： PURPOSE:To precisely form a turning center on a column selected as the turning center in the case of wrecking a structure by way of overturning it. CONSTITUTION:A section 3 of a column member 1 is cut from both sides to portions adjacent to a reinforcing bar 2 in the neighbourhood of a neutral axis of the section 3 of the column member 1 of a structure consisting of reinforced concrete. Thereafter, by loading an explosive 4 along the neutral axis and blasting it, the concrete is blasted and the reinforcing bar 2 in the neighbourhood of the neutral axis is remained.

摘要： PURPOSE:To reduce the amount of explosive to be used, to easily and steadily overturn a structure in the targeted overturning direction and at a targeted position and to safely demolish the structure. CONSTITUTION:Working to make a turning center 11 at the time of overturning a structure is applied to the bottom part of a column 4 facing an external wall in the opposite direction of overturning of the structure, parts (1A, 2A, 3A, etc.) are blasted upward from the bottom part of front vertical members in the overturning direction from the column 4, and the structure is overturned by an unbalance moment generated around the turning center 11 by undestructed remaining parts of the structure. After overturning the structure, secondary treatment is applied to the undestructed remaining parts.

摘要： PURPOSE:To blast a pipe member by the buckling of the pipe member due to explosion of an explosive by mounting a plurality of shaped charges in the direction corresponding to the axial direction of the pipe member at regular intervals in the circumferential direction on the inner circumference or outer circumference of the pipe member constituting a structure. CONSTITUTION:A plurality of shaped charges 12 in length (a) previously calculated for generating a buckling are juxtaposed in the horizontal inner circumferential direction at regular intervals (b) on an outer circumference or an inner circumference in a part of a pipe member 11, and the shaped charges 12 are installed in the direction corresponding to the axial direction of the pipe member 11. Accordingly, the standoff of each shaped charge and the pipe member can be kept at an optimum fixed value, thus previously avoiding the interference of a Netumann's jet.

摘要： PURPOSE:To make a destructed form compact, to reduce crushed rubble and to reduce construction cost for a wall member with many reinforcements. CONSTITUTION:On an upper end part, a lower end part and a central part of a wall member 2 of a structure, local cutouts 3 are provided on the same wall surface (4) side as regards the upper end part and the lower end part and a wall surface (5) side opposite to the upper end part and the lower end part as regards the central part. By blasting a column member 7 adjacent to both sides of the wall member 2 in the cross direction and supporting a beam member 6 passing the upper end of the wall member 2, the wall member 2 is deformed by bending it square by vertical force generated on vertical both ends of the wall member 2 so that it is projected to the side of the wall surface (4) opposite to the cutouts 3 at the central part. Thereafter, by folding the wall member 2 in the vertical direction, it is blasted.

摘要： PURPOSE:To effectively perform blasting work by eliminating a main cause of misfiring such as the generation of an electric current with high-frequency wave or a dielectric breakdown, by a method wherein the detonating circuit in a detonator is isolated from an electric source part and is either connected to an electric detonator or provided in the vicinity thereof, and mainly a charged current is caused to flow in a bus bar. CONSTITUTION:A charge-starting switch is turned on and an electric current is applied to a detonating circuit part 12 for the time required. In this way, a condenser 16 begins to be charged with the electric current through a step-up circuit 15. At the same time, a reset circuit 19 actuates a CR timer 17 and specified time is measured. During this time, the condenser 16 is charged with the electric current. Since a charge is finished after 30sec., the CR timer 17 sends its finished signal to a breaker circuit 14 and an electric source is cut off. When this electric source is cut off, a service interruption-detecting circuit 18 is actuated, and the electric current, with which the condenser 16 is charged, flows on the side of a blasting circuit and detonates an electric detonator 13.

摘要： PURPOSE:To provide a method for designing blasting destruction capable of analyzing the destruction of a structure even with a small number of elements and accurately predicting beforehand the final blasting destruction state of the structure. CONSTITUTION:The destruction type of the structure is set by studying peripheral conditions, protection work quantity, previous work quantity and various other elements at the time of designing the blasting destruction of the structure 3. The sureness of the destruction is then confirmed by way of static and dynamical confirmation means by simulation and finally explosion-initating order and blasting second difference are set. Further, a discontinuods deformation method is used in the dynamical confirmation processing by simulation, where studies are made by dividing the structure into a block element 1 and a block element 2 from its shape, arrangement state of bars, material characteristics, etc. As a result, the yield of reinforcing bars, the pull out thereof from concrete and the division by fall of the concrete, etc., are analyzed in compliance with the actual structure destruction. The accurate prediction of the destruction of the structure is made thus possible.

摘要： PURPOSE:To enhance the safety of work by installing an inner extacted part to a post material and blasting and breaking into pieces a vertical portion of one side during breakdown and generating unbalanced moments and forcing the vertical portion of the other side to yield to the bending, thereby providing a rotary hinge to the portion. CONSTITUTION:An inner extracted part 3 is preliminarily installed to a reinforcing concrete post member 2 outside a structure. The member 2 is rotary-hinged at three locations between a lower end part, a middle part and an upper end part per floor. Then, a vertical portion 2b inside the lower end of the member 2, and a vertical portion 2a outside the middle part and the vertical portion 2b inside the upper end are blasted and broken into pieces while a reinforcing concrete post member 4 is blasted and broken into pieces all over the whole length as well. Then, an unbalanced moment is generated inside the upper end and outside the middle part and inside the lower end of the member 2 where the vertical part 2a outside the lower end, a vertical part 2b inside the middle part and a vertical part 2a outside the lower end are bent and yielded. The member 2 is bent inwardly in the shape of dog leg and collapsed so that each floor may vertically move just under the member as a sandwiched state.
