Artificial island structure for relay extension of suspension tunnel
The invention discloses an artificial island structure for relay extension of a suspension tunnel. The artificial island structure comprises a lower island foundation and an upper vertical island body; the island foundation is constructed by multiple layers of backfill sand, each layer of the backfill sand is constructed in cofferdams formed by submergence of a super large concrete floating box, the peripheral dimension of each layer of the cofferdam gradually decreases upward, and thus the shape of the island foundation is in a pyramid shape; the upper vertical island body is composed of an island wall and an island inner body; the island wall is composed of a steel cylinder grid body and a dense filler in the steel cylinder grid, the steel cylinder grid body is formed by mutually connecting a steel large cylinder main grid and a straight web steel plate pile sub-grid, the steel large cylinder main grid and the straight web steel plate pile sub-grid correspondingly need to be subjected to sand backfilling and compaction, and within 1 m from the top in the island wall, surface protection is conducted by a broken stone cushion and a block stone cushion; and the island inner body iscomposed of backfill sand. According to the artificial island structure, the characteristics of self stability, construction difficulty and relatively small engineering quantity are achieved, and theartificial island structure can be used for relay extension of the suspension tunnel and anchorage of a cable in sea.
本发明公开了一种用于悬浮隧道接力延伸的人工岛结构，包括下部的岛基和上部的直立式岛体；岛基由多层回填砂构筑而成，每层回填砂采用在超大型混凝土浮箱下潜形成的围堰中构筑，且每层围堰的外围尺寸向上逐渐减小，使岛基的外形呈金字塔形；上部直立式岛体由岛壁和岛内体构成；岛壁由钢筒式格体及其内部的密实填料共同构成，钢筒式格体由钢质大圆筒主格与直腹式钢板桩副格相互连接而成，钢质大圆筒主格内和直腹式钢板桩副格内均要回填砂并加以密实，岛壁内距顶部1m范围内采用碎石垫层与块石垫层护面；岛内体由回填砂构成。本发明的人工岛结构，具有自身稳定、施工难度和工程量相对较小的特点，能用于悬浮隧道的接力延伸和拉索的海中锚碇。
