Construction method of marine steel shell immersed tube tunnel
The invention discloses a construction method of an ocean steel shell immersed tube tunnel, and belongs to the technical field of ocean tunnel construction. Comprising the steps of manufacturing steel shell immersed tube joints, constructing tunnel piers and installing the steel shell immersed tube joints. The method for manufacturing the steel shell immersed tube joint comprises the following steps: manufacturing the steel shell tube joint in a dock or a tunnel dock of a shipyard; a water stop belt is installed on the end face of one end of the steel shell pipe joint; steel plate end sealing doors are installed at pipe joint cavity openings in the two ends of the steel shell pipe joint; opening the dock or the tunnel dock to discharge water; the steel shell pipe joint is hauled to a wharf of a construction site to be stopped; enabling the steel shell pipe joint to float on the sea surface by taking seawater of a wharf on a construction site as a construction platform for manufacturing the steel shell pipe joint to be immersed; according to the tunnel pier construction procedure, immersed tube supporting pier mechanisms are arranged at intervals in the length direction of the ocean steel shell immersed tube tunnel with a seabed as a foundation, and the opposite ends of every two adjacent steel shell tube joints share one immersed tube supporting pier mechanism. The method has the advantages that deep-sea tunnel construction difficulty is reduced; the construction period is shortened, and project cost and project investment are reduced.
一种海洋钢壳沉管隧道的施工方法，属于海洋隧道施工技术领域。包括制作钢壳沉管管节、隧道墩施工工序和安装钢壳沉管管节；制作钢壳沉管管节包括的步骤：在船厂的船坞或隧道坞内制作钢壳管节；在钢壳管节的一端端面安装止水带；对钢壳管节的两端的管节腔口安装钢板端封门；对船坞或隧道坞开闸放水；将钢壳管节拖运至施工现场码头停靠；以施工现场码头的海水作为制作钢壳待沉管管节的施工平台而使钢壳管节浮在海面上；隧道墩施工工序为：以海床为地基沿着海洋钢壳沉管隧道的长度方向间隔设置沉管支承墩机构，各两相邻的钢壳管节的相向一端共用一个沉管支承墩机构。优点：化解深海隧道建设难度；缩短工期，降低工程造价和工程投资。
