Construction method of terrain-limited ultra-shallow-buried shield tunnel anti-floating structure system
The invention provides a construction method of a terrain-limited ultra-shallow-buried shield tunnel anti-floating structure system, which comprises the following steps: before a shield tunneling machine reaches an ultra-shallow-buried section, arranging large pipe sheds at intervals on one side of the axis of a shield tunnel along a hillside, and arranging foundation piles at intervals on the other side of the axis of the shield tunnel; a concrete beam is constructed on the pile top of the foundation pile, the concrete beam is formed by connecting a foundation pile top concrete beam and a connecting beam, meanwhile, a large pipe shed end concrete beam is constructed at the end of the large pipe shed, and the concrete beam and the large pipe shed end concrete beam are connected end to end to form a closed beam; concrete slab reinforcing steel bars are bound between the concrete beams and the large pipe shed end concrete beams, then concrete is poured, construction of a concrete cover plate is completed, and the concrete cover plate is located above the shield tunnel; the concrete beam, the concrete cover plate and the concrete beam at the end of the large pipe shed are connected into a whole and form an anti-floating structure system together with the foundation pile and the large pipe shed. The method is simple, easy to operate, safe and reliable, and cost is saved.
本发明提供了一种地形受限超浅埋盾构法隧道抗浮结构体系的施工方法，盾构机到达超浅埋段之前，在盾构法隧道轴线一侧沿山坡间隔设置大管棚，在盾构法隧道轴线另一侧间隔设置基桩；在基桩的桩顶施作混凝土梁，混凝土梁由基桩顶部混凝土梁和连接梁连接组成，同时在大管棚的端部施作大管棚端部混凝土梁，混凝土梁与大管棚端部混凝土梁首尾相接，形成闭合梁；在混凝土梁、大管棚端部混凝土梁之间绑扎混凝土板钢筋，然后浇筑混凝土，完成混凝土盖板的施作，混凝土盖板位于盾构法隧道上方；混凝土梁、混凝土盖板、大管棚端部混凝土梁连接成为一个整体，与基桩、大管棚共同形成抗浮结构体系。本发明简单易操作、节约造价、安全可靠。
