Construction method of seabed steel shell immersed tube tunnel
The invention discloses a construction method of a submarine steel shell immersed tube tunnel, and belongs to the technical field of submarine tunnel construction. Comprising the steps of manufacturing steel shell immersed tube joints, constructing a tunnel foundation and installing the steel shell immersed tube joints. The step of manufacturing the steel shell immersed tube joint comprises the following steps: manufacturing the steel shell tube joint on a shipyard dock or a tunnel dock, arranging a steel shell tube joint water inlet pipe valve on the side part of the steel shell tube joint, arranging a steel shell tube joint exhaust pipe valve on the upper part of the steel shell tube joint, and forming a concrete pouring hole and a concrete pouring exhaust hole in the upper surface of the steel shell tube joint; 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 a gate of a shipyard dock or a tunnel dock to discharge water; or the steel shell pipe joint slides into water through the slipway; the steel shell pipe joint is hauled to a wharf of a construction site to be stopped; seawater of a wharf on a construction site is used as a construction platform for manufacturing the steel shell pipe joint to be immersed, so that the steel shell pipe joint floats on the sea surface. The method has the advantages of saving resources, shortening the construction period and greatly reducing the project cost and project investment.
一种海底钢壳沉管隧道的施工方法，属于海底隧道施工技术领域。包括制作钢壳沉管管节、隧道基础施工和安装钢壳沉管管节；制作钢壳沉管管节包括的步骤：在船厂船坞或隧道坞制作钢壳管节，在钢壳管节的侧部设有钢壳管节进水管阀、在钢壳管节的上部设有钢壳管节排气管阀，在钢壳管节的上表面设混凝土浇筑孔及混凝土浇筑排气孔；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；对船厂船坞或隧道坞开闸放水；或者通过船台将钢壳管节滑入水中；将钢壳管节拖运至施工现场码头停靠；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。优点：节约资源，缩短工期，大降低工程造价和工程投资。
