Title:
TUBE JOINT STEEL PLATE CONCRETE COMBINED STRUCTURE FOR IMMERSED TUBE TUNNEL, AND METHOD FOR MANUFACTURING TUBE JOINT STEEL PLATE CONCRETE COMBINED STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2024/051284
Kind Code:
A1
Abstract:
The present invention relates to the technical field of immersed tube tunnels, and provides a tube joint steel plate concrete combined structure for an immersed tube tunnel, and a method for manufacturing the tube joint steel plate concrete combined structure. The combined structure comprises a top plate structure, an outer wall structure, a middle wall structure, and a bottom plate structure, wherein the top plate structure has an opening portion, and comprises a steel plate assembly, connecting elements and steel bars, the steel bars being connected to the steel plate assembly by means of the connecting elements to form a framework structure, and concrete being poured into the framework structure through the opening portion; and each of the outer wall structure, the middle wall structure and the bottom plate structure comprises a closed steel-clad steel shell, and concrete is poured into the closed steel-clad steel shells. According to the present invention, the overall strength, rigidity, waterproofness and durability of the tube joint structure can be met, the convenience of pouring construction on tube joint concrete is improved by means of the opening type operation condition of the top plate structure, and the construction quality is guaranteed; moreover, common concrete can be used, such that the manufacturing cost is greatly saved on. The structure and the construction method are suitable for underwater floating state pouring construction of immersed tube tunnels, and can also be applied to immersed tube tunnels under various conditions.
