WATER STOP STRUCTURE OF ROAD BRIDGE JOINT PART
PROBLEM TO BE SOLVED: To provide a water stop structure capable of easily constructing and preventing water leakage for long term when an expansion device is installed, replaced or repaired.SOLUTION: A water stop structure includes: an incompressible first cut-off material 14 which is formed by filling an upper part of a joint gap 7 in a joint part of a road bridge with a liquid rubber; a second compression-restorable cut-off material 15 which is engaged with a lower part of the joint gap 7 in a compressed state; an intermediate material 16 which is provided between the first cut-off material 14 and the second cut-off material 15 to prevent interference of a deformation of the first cut-off material and a deformation of the second cut-off material with each other.
【課題】伸縮装置の新設、取替、及び補修において、施工が容易で且つ長期にわたって漏水防止効果が得られる工法を提供する。【解決手段】道路橋継目部の遊間７の上部に液状ゴムを充填することによって設けられた非圧縮性の第１止水材１４と、遊間７の下部に圧縮状態で嵌められて設けられた圧縮復元性を有する第２止水材１５と、第１止水材１４と第２止水材１５の間に設けられ、第１止水材の変形と第２止水材の変形とが相互に干渉することを抑制する中間材１６とを備えている。【選択図】図３
