Artificial island type intermediate well structure of seabed tunneling tunnel
The invention discloses an artificial island type intermediate well structure of a seabed tunneling tunnel. The artificial island type intermediate well structure is arranged on intermediate well artificial islands arranged at intervals in the axis direction of the seabed tunneling tunnel; the plane of each intermediate well artificial island is in an oval shape with a notch and is divided into anisland inner part and an island outer part; the section structure of each island inner part comprises a lower island base and an upper vertical island body; each island base is constructed by multiple layers of backfill sand, each layer of backfill sand is constructed in a cofferdam formed by submerging an ultra-large concrete buoyancy tank, and each island base is pyramid-shaped; each island body is composed of an island wall and an island inner body; each island wall is composed of a steel cylinder type grid body and dense filler in the steel cylinder type grid body; each island inner bodyis backfill sand filled in the island wall; each island outer part is positioned at the reverse flow end of the intermediate well artificial island and is provided with a material wharf, a breakwaterand a harbor basin; and an intermediate well is arranged in each island inner part, is of a shaft type reinforced concrete structure and is arranged in a deep foundation pit support structure. According to the structure, the intermediate well can be prevented from directly bearing impact of deep sea wind, waves and flow.
本发明公开了一种海底掘进隧道的人工岛式中间井结构，设在沿海底掘进隧道的轴线方向间隔设置的中间井人工岛上；每座中间井人工岛的平面呈带缺口的椭圆形，并分为岛内部分与岛外部分；岛内部分的断面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，岛基的外形呈金字塔形；岛体由岛壁和岛内体构成；岛壁由钢筒式格体和其内部的密实填料共同构成；岛内体为填筑在岛壁内的回填砂；岛外部分位于中间井人工岛的逆流端并布置材料码头、防波堤与港池；中间井设在岛内部分并为井筒式钢筋混凝土结构且设在深基坑围护结构内。本发明能避免中间井直接承受深远海风、浪、流的冲击。
