Title: Segment ring for shielding work
Inventor: ENDO FUSAO
IPC: E21D11/08
Filed: 1989-02-17
Abstract: PURPOSE:To prevent the damage to corners by a method in which a trapezoidal planar form of key segments facing each other are connected with segments in a ring form, and the front of the key segments is shaped into an inversed trapezoidal form toward the center. CONSTITUTION:A pair of key segments 1K and 4K facing each other are connected with segments 2B, 6B, 3B, and 5B in a ring form. The segments 1K and 4K are of a trapezoidal planar form, in which an inversed trapezoidal form which becomes narrowed toward the center of the segment ring 1R is formed between sides along the longitudinal direction of the tunnel. When using the key segments 1K and 4K, the same shape of the key segments are used regardless of the bending direction of the shield tunnel. The stroke of shield jack can thus be shortened beyond the width of one ring.
