摘要： PROBLEM TO BE SOLVED: To largely reduce cost by implementing a countermeasure while operating a tank without requiring to remove and transfer an existing pipe, while easily implementing a local part slide countermeasure of an existing structure such as an existing tank. SOLUTION: A required safety factor 1.1 is secured by improving a safety factor by increasing a resistance force to a slide by driving a plurality of steel bar-shaped members 3 such as a well point pipe and a reinforcement of a thick diameter at a predetermined interval in the tank radial direction in a predetermined range in the tank radial direction of the outside peripheral ground of the existing tank 1 to the local part slide surface (a circular arc slide surface) A of the existing tank (an old law tank) 1 manufactured at an old standard. The bar-shaped members 3 are arranged in an existing area of the local part slide A so as to penetrate the local part slide surface A, and also arranged in an outside area of the local part slide surface A, and the required resistance force is secured.

摘要： PROBLEM TO BE SOLVED: To ensure safety and reduce the construction cost by arranging long face bolts taking fiber reinforced plastic cable bolt as a core material at suitable intervals in the working face in the interior surrounded with a pipe loop constructed extending over the total length of a start vertical shaft and an arrival shaft, and digging while breaking the bolts. SOLUTION: A boring machine 4 is installed on the start vertical shaft 2 side, and a steel pipe 5 is propelled extending the total length from the start vertical shaft 2 to an arrival shaft 3 to construct a pipe roof 6. Subsequently in the interior surrounded with the pipe roof 6, long face bolts 12 having a core material of a fiber reinforced plastic cable bolt having such a length as to extend over the total length of the start vertical shaft 2 and the arrival shaft 3 are arranged at suitable spaces from the working surface parallel to each other. Drilling is started from the start vertical shaft 2, and with the advance of drilling, a timbering is assembled, an intermediate working floor is installed in the middle stage by use of an H-steel and a lining plate, and drilling is performed while the long face bolts 12 are broken by an excavator such as a back hoe or the like on the intermediate working floor.
