Abstract

The invention provides a construction method of a large-diameter steel-concrete combined cylindrical structure, which comprises the following steps: manufacturing a steel cylinder body and dowel bars: manufacturing the steel cylinder body and a plurality of dowel bars, and forming a notch in the lower end part of each dowel bar; the dowel bars and the steel cylinder are installed, specifically, the dowel bars are vertically inserted into the upper end of the cylinder wall of the steel cylinder at intervals through the notches to be fixed; the supporting structure comprises a plurality of transversely-arranged supporting rods, one end of each supporting rod is connected with one dowel bar, and the other ends of the supporting rods intersect and are fixed on the central axis of the steel cylinder; manufacturing and mounting of an annular driver: fixedly connecting the annular driver with the upper end part of the dowel bar; vibration sinking construction is conducted, specifically, a vibration sinking tool is installed for vibration sinking, and after vibration sinking construction is completed, the annular replacement hitting structure and the supporting structure are dismantled; prefabricating the concrete cylinder; and mounting the concrete cylinder. According to the construction method, the construction cost can be effectively reduced, engineering manufacturing is easy, and the obtained cylindrical structure is high in durability.

Description

technical field [0001] The invention belongs to the technical field of cylindrical bank revetment structures of offshore artificial islands in soft ground areas, and in particular relates to a construction method for a large-diameter steel-concrete composite cylindrical structure. Background technique [0002] The large-diameter steel cylinder revetment structure is a new type of structure used in the construction of offshore artificial islands. It has been verified that the structure has fast construction, engineering manufacturing, and The characteristics of low environmental impact are the key technologies to realize the rapid construction of artificial islands. [0003] However, the diameter of the steel cylinder revetment structure is relatively large, generally between a dozen meters and tens of meters. For example, the diameter of the steel cylinder used for the artificial island of the Hong Kong-Zhuhai-Macao Bridge is 22m, and the diameter of the steel cylinder used ...
