Sea area artificial island backfilling island and undercrossing tunnel excavation method
The invention relates to a sea area artificial island backfilling island and undercrossing tunnel excavation method, which comprises the following steps: an existing building enclosure is constructed around an existing building to form a first enclosure structure, so that the existing building is positioned in the first enclosure structure; backfilling an island; excavating and supporting the underneath pass foundation pit, enclosing a foundation pit area between adjacent existing buildings by adopting a first enclosing structure surrounding the existing buildings, and constructing in the foundation pit area outside the existing buildings to form a second enclosing structure; compensation and deviation correction are conducted, specifically, the pressure of jet grouting pile construction is controlled, and the existing buildings on the two sides of the foundation pit deform and deviate towards the side deviating from the foundation pit; automatic compensation is carried out, and a servo supporting structure is constructed in the second enclosure structure and between the first enclosure structures on the two sides of the foundation pit; it is guaranteed that the existing building is not prone to deviation or inclination in the backfilling process, potential safety hazards caused to the existing building in the island backfilling process are reduced, and the island backfilling efficiency is improved.
本发明涉及一种海域人工岛回填筑岛及下穿隧道开挖的方法，包括以下步骤：既有建筑围护，围绕既有建筑施工形成第一围护结构，使得既有建筑位于第一围护结构内；回填筑岛；下穿基坑开挖支护，处于相邻既有建筑间的基坑区域，采用围绕于既有建筑的第一围护结构进行围护，在既有建筑之间以外的基坑区域施工形成第二围护结构；补偿纠偏，控制旋喷桩施工的压力，使得基坑两侧的既有建筑向背离基坑侧形变偏移；自动补偿，在第二围护结构内和基坑两侧的第一围护结构之间施工形成伺服支撑结构；保证既有建筑在回填中不易出现偏移或倾斜，降低回填筑岛过程中对既有建筑造成的安全隐患，提高了回填筑岛的效率。
