摘要： PROBLEM TO BE SOLVED: To attain a compact configuration with a simple structure. SOLUTION: A firing driving gas chamber 33 is formed at a base end of a firing cylinder 3 to which a firing member 21 is slidably fitted. A firing air opening 36 for use in communicating a firing pressure accumulating chamber 35 formed at an outer circumferential part of the base end side of the firing cylinder 3 with the firing driving gas chamber 33 is formed at a cylinder wall. The firing air opening 36 is closed by a closed surface 23a at an outer circumference of a piston member 23 of the charged firing member 21, energizing air for a high pressure air bomb for triggering operation is fed from a triggering port 37 into the firing driving gas chamber 35 through a firing valve to push out the piston member 23. As a result, the firing air opening 36 is released, high pressure air in the firing pressure accumulated chamber 35 is fed at once into the firing driving gas chamber 33, and then the firing member 21 is fired.

摘要： PROBLEM TO BE SOLVED: To destroy an article to be destroyed surely by installing a cover member to a destroying vessel for filling a substance for destruction destroying the article to be destroyed and forming a hole for filling for filling the cover member with the substance for destruction and a hole for an air vent. SOLUTION: Electrodes 8 connected by a small-gage wire 2 are inserted to a cover member 7 and mounted on a destroying vessel 6, and the destroying vessel 6 is buried beforehand into a mounting hole 5 formed to an article to be destroyed 4. When the article to be destroyed 4 is used completely and destruction is conducted, a pipe 9 for infection is inserted into a hole 7a for filling, and filled with a substance 3 for destruction. Air in the destroying vessel 6 is discharged from a hole 7b for an air vent with the filling of the substance 3 for destruction at that time. The pipe 9 for injection is extracted, and the hole 7a for filling and the hole 7b for the air vent are plugged. The metallic small-gage wire 2 is supplied with electric energy from the electrodes 8, and the article to be destroyed 4 is broken. Accordingly, since the substance for destruction is filled at the time of destruction, the deterioration with time of the substance for destruction need not be considered, and the article to be destroyed can be broken and weekened surely.

摘要： PROBLEM TO BE SOLVED: To reduce the weight of a block and facilitate the production thereof, by providing a receive plate of load at the top and bottom faces of a block body made of a rigid plastic foam. SOLUTION: A foundation block 1 supporting a temporary bridge or road or the like in an emergency is constituted of a block body 2 made of a rigid plastic foam, receive plates 3, 4 provided at the top and bottom faces thereof, and a middle plate 5 arranged at the intermediate position. Steel, aluminum, reinforced plastics, or wooden materials are used for these plates. Or instead of these materials, the outer periphery of the block body 2 is covered with a reinforcing cylinder body. In this way, the block can be lightened and the compressive strength can be increased. And hence, construction and transportation can be facilitated. And since the structure is simple, it can be easily produced. And since the load F is dispersed on the whole face of the plates 3, 4, the block brings out an excellent compressive resistance and supports a heavy structure. And further, when a reinforcing cylinder is provided, a horizontal swelling is restricted and the supporting force can be increased further.
