Investigation regarding cost reduction in small-size shield work

Study period:1998 - 1999
Research overview:
In this study, we are going to arrange problems in a cost reduction for rationalizing a method of construction of a small-size shield work which is predicted to increase in the future, and to propose a cost reduction method. We examined respectively rationalization of steel segment structure, erosion-resistance and water-resistance to omit secondary covering work, and adaptability of a segment formed of new materials so as to rationalize a small-size shield work, also computed a cost, and examined the effect of cost reduction. As a result, it could be recognized that from 2 to 9 % of cost could be reduced, and the period necessary to the construction could be shortened by 2 to 15 %.
