Abstract
PURPOSE: To prevent the breakage of a longitudinally-directional coupling by interposing a high strength, low rigid plastic-made earthquake resistant washer between a nut screwed in the coupling bolt of a longitudinal direction coupling and a coupling plate having a coupling bolt pierced therethrough. CONSTITUTION: When a buried tunnel is executed, a number of divisional parts are made, and adjacent segments 1, 1 are formed via longitudinal direction couplings 2, 2. Furthermore, each ring-shaped, high strength, low rigid plastic earthquake resistant washer 7 is put from the tip end of a coupling plates 3, 3 of couplings 2, 2. The coupling plates 3, 3 are fastened to each other with predetermined force by a nut screwed from the tip end of the bolt. Therefore, even in the case where excessive force may exert the couplings 3, 3 by an earthquake, the coupling plates 3, 3 can be prevented from being broken through deformative absorption of the washer 7.
