摘要： PROBLEM TO BE SOLVED: To more facilitate the flaw inspection of a tank equipped with a heat insulating material. SOLUTION: The tank inspection device 10 is adapted to the tank 1 equipped with inner tank plates 3, 4 and 26 for forming a storage tank for storing a liquid and an outer tank plate 2 for forming heat insulating layers, each of which has heat insulating materials 6 and 7 arranged in it, in the gaps between the inner tank plates 3, 4 and 26 and utilized when the cracks 27 formed in the inner tank plates 3, 4 and 26 are inspected. The tank inspection device 10 is equipped with an ultrasonic flow detection sensor 31 for detecting a flaw using an ultrasonic wave and the rod 11 having the ultrasonic flow detection sensor 31 arranged to its leading end 33. The rod 11 is longer than the thickness of both of the heat insulating materials 6 and 7. In the tank inspection device 10 thus constituted, the rod 11 is passed through the hole 21 formed in the outer tank plate 2 to allow the ultrasonic flow detection sensor 31 to easily arrive at the inner tank plates 3, 4 and 26 and the inner tank plates 3, 4 and 26 can be easily subjected to flaw detection without removing the outer tank plate 2 and the heat insulating materials 6 and 7 from the tank 1.

摘要： PROBLEM TO BE SOLVED: To prevent the damage of a handrail in a dome roof such as a storage tank in which a corridor is arranged around its periphery, by inclining a corridor tread to be lowered toward the outside, fixing a handrail of the corridor in an upright position when the corridor is used, and moving it in a position except for the upright position at the time of a snowfall. SOLUTION: A corridor tread 6 is attached between the periphery of a dome 2 and a peripheral beam 8 while being inclined so as to be lowered toward the outside. The corridor tread 6 is appropriately set at an inclination angle of 6 to 10 deg.. When a corridor is used, a handrail 7 is attachably/detachably inserted in an attaching metal fitting 11, and fixed in an upright position against the corridor tread 6. Also, at the time of a snowfall, the handrail 7 is removed from the female screw sleeve 10 of the attaching metal fitting 11. Under this condition, snow lain on the dome 2 slide on the corridor tread 6 without being disturbed by the handrail 7, and falls from the outer side of a storage tank side plate 1 to the lower part.
