    • A method of making a primary concrete covering wall on the surface of the wall of a tunnel which extends behind a shield type tunnel excavator. A form structure for casting concrete to make the covering wall is assembled with a plurality of arcuate form assemblies respectively including form segments and timbering members for reinforcing the cast and set concrete. The form segments of each assembly are detachably coupled to the timbering member. The form structure is disassembled after the cast concrete is set by detaching the form segments of the respective assemblies from the timbering members to leave the members on the primary covering wall of the set concrete, whereby the primary covering wall can be held in stable state simultaneously with completion of the primary covering wall on the tunnel wall surface.
    • 一种在盾构式隧道挖掘机后面延伸的隧道墙壁表面上制作主混凝土覆盖墙的方法。 用于铸造混凝土以形成覆盖壁的形式结构组装有多个弓形模板组件,分别包括用于加强铸造和混凝土的模板段和木构件。 每个组件的形状段可拆卸地联接到木材构件。 通过将各个组件的形状段从木构件上拆下来将构件放置在集合混凝土的主覆盖壁上之后,通过将浇注混凝土固定在浇筑混凝土之后拆卸模板结构,从而使初级覆盖壁可以同时保持在稳定状态 完成隧道墙壁上的主覆盖墙。
