SELF-POSTURE CONTROL TYPE SUBMERGED CAISSON AND CONSTRUCTION METHOD OF SUBMERGED TUNNEL
PROBLEM TO BE SOLVED: To provide a self-posture control type submerged caisson which can dispense with work for installing, on a water bottom, a reaction member of a height-adjusting jack of the submerged caisson which is performed prior to the installation of the submerged caisson, and work for adjusting a horizontal jack between bulkheads of the submerged caisson, and can largely shorten a construction period, and a construction method of a submerged tunnel.SOLUTION: A self-posture control type submerged caisson 10 comprises: a submerged caisson 1; a reaction force pedestal 2 which is arranged below the submerged caisson 1; and a vertical jack 3 and a horizontal jack 4 which are arranged between the submerged caisson 1 and the reaction force pedestal 2. The reaction force pedestal 2, the vertical jack 3 and the horizontal jack 4 are arranged at the submerged caisson 1 in advance prior to installation.
【課題】沈埋函の沈設に先行しておこなわれている、沈埋函の高さ調整用ジャッキの反力部材を水底上に設置する作業、および沈埋函のバルクヘッド間に水平ジャッキを設置する作業をともに不要にでき、もって工期の大幅な短縮を図ることのできる自己姿勢制御型沈埋函と沈埋トンネルの施工方法を提供する。【解決手段】沈埋函１と、沈埋函１の下方に配設されている反力架台２と、沈埋函１と反力架台２の間に配設された鉛直ジャッキ３および水平ジャッキ４と、を備え、沈設に先行して反力架台２と鉛直ジャッキ３と水平ジャッキ４が沈埋函１に対して予め装備されている、自己姿勢制御型沈埋函１０である。【選択図】図１
