Abstract (en)
A system forming a tunnel beneath a railway (1) comprises a tunnel member (3) a platform member (2) eight support members (4), a slide member (5) for the tunnel member (3), and two slide members (6) for the platform member (2). In use, the tunnel member (3) is constructed in-situ adjacent to one side of the railway (1) resting upon the tunnel slide member (5), and the platform member (2) is constructed in-situ adjacent to the opposite side of the railway (1) resting upon the pair of platform slide members (6). A section of the railway (1) is then removed and part of the ground that was beneath the removed section of the railway (1) is excavated. The platform member (2) is pushed along the platform slide members (6) until the platform member (2) is resting upon the eight support members (4), and the removed section of the railway (1) is then replaced. The ground beneath the railway (1) and the platform member (2) is then excavated, and the tunnel member (3) is pushed along the tunnel slide member (5) until the tunnel member (3) is under the railway (1). The tunnel slide member (5) and the platform slide members (6) are then removed. In this manner the tunnel is formed beneath the railway (1).
