Description

沉管隧道用管节钢板混凝土组合结构及其制造方法Pipe section steel plate concrete composite structure for immersed tube tunnel and manufacturing method thereof 技术领域Technical field
本发明涉及沉管隧道技术领域,尤其涉及一种沉管隧道用管节钢板混凝土组合结构及其制造方法。The invention relates to the technical field of immersed tube tunnels, and in particular to a tube-section steel plate concrete composite structure for immersed tube tunnels and a manufacturing method thereof.
背景技术Background technique
目前,国内已建成的沉管隧道用管节主体结构的构造形式一般采用钢筋混凝土结构或钢壳混凝土组合结构。At present, the structural form of the main structure of the pipe joints for immersed tube tunnels that have been built in China generally adopts reinforced concrete structures or steel shell concrete composite structures.
钢筋混凝土结构的制作步骤包括:通过架设模板、绑扎钢筋骨架和浇筑混凝土,混凝土冷凝后与钢筋骨架形成整体受力结构。普通建设条件下混凝土结构沉管管节具有施工便利、技术成熟、工程经济性好等特点。The manufacturing steps of the reinforced concrete structure include: erecting formwork, tying the steel frame and pouring concrete. After the concrete is condensed, it forms an overall stress-bearing structure with the steel frame. Under ordinary construction conditions, immersed tube sections in concrete structures have the characteristics of convenient construction, mature technology, and good project economy.
钢壳混凝土结构的制作步骤包括:通过封闭外包钢壳(腔体形式)、横纵向加劲肋板、横纵向钢隔板或钢桁架及充填于钢壳中的混凝土。钢壳混凝土结构能够提高管节结构的强度、刚度、防水性、耐久性等多种性能,可用于高水压、大埋深、大跨度、高防水性、高耐久性或其他特殊要求下的沉管管节结构。The manufacturing steps of the steel shell concrete structure include: closing the outer steel shell (cavity form), transverse and longitudinal stiffening ribs, transverse and longitudinal steel partitions or steel trusses and filling the concrete in the steel shell. The steel shell concrete structure can improve the strength, stiffness, waterproofness, durability and other properties of the pipe section structure. It can be used in projects with high water pressure, large burial depth, large span, high waterproofness, high durability or other special requirements. Immersed tube section structure.
当沉管隧道遇到高水压、大埋深、大跨度、高防水、高耐久性及其他特殊要求时,钢筋混凝土结构由于所需配置的钢筋过多而导致浇筑混凝土极为困难、甚至无法浇筑,而钢壳混凝土组合结构采用全封闭钢壳(腔体形式),对于顶板,浇筑较困难,易形成脱空,降低结构的承载能力,且混凝土必须采用特殊配制的自密实混凝土,造价昂贵。而且,当隧道建设缺乏干坞或预制场建设场地或者建设干坞的经济性很差时,要求管节钢壳采用水中浮式浇筑混凝土时,顶板的封闭结构十分不利于浇筑质量的控制和工期保障。When an immersed tube tunnel encounters high water pressure, large burial depth, large span, high waterproofing, high durability and other special requirements, the reinforced concrete structure requires too much steel, making it extremely difficult or even impossible to pour concrete. , while the steel shell-concrete composite structure uses a fully enclosed steel shell (cavity form), the roof is difficult to pour, and it is easy to form voids, which reduces the load-bearing capacity of the structure, and the concrete must be specially prepared self-compacting concrete, which is expensive. Moreover, when there is a lack of dry dock or prefabricated yard construction space for tunnel construction or the economics of building a dry dock is very poor, and the pipe section steel shell is required to be floated in water to pour concrete, the closed structure of the roof is very detrimental to the control of pouring quality and construction period. Assure.
