Abstract

Traffic jams occur frequently due to the dense populations of cities. Accordingly, the discomfort of citizens has increased. In order to minimize traffic inconveniences, various public transportation facilities have been suggested. In this paper, for the economical construction of a near-surface railway system, the design of a trench shield is developed and a review of its applicability is done by creating and testing trench shield equipment on a small scale. The trench shield consists of an excavation part, a shield part and an advancement part. To examine the applicability of the trench shield, a laboratory test is carried out. The results of the laboratory test confirm the possibility of reducing the construction time at open-cut construction sites through the excavation of the trench shield. Although the laboratory test is an indoor and relatively small-scale experiment, it is considered to be possible to secure a construction speed of 3m/day when the trench shield equipment is used.
