城市道路地下结构清水混凝土模板施工技术

Construction Technology for Formwork of Fair-faced Concrete of Underground Structures of Urban Roads

为总结地下结构工程清水混凝土模板施工技术,以无锡太湖大道节点改造工程SD3标为例,介绍无锡太湖大道节点改造工程结构施工的特点和要求,着重介绍清水混凝土模板的选型、设计、安装和拆除等关键技术。实践证明:1)在地下结构清水混凝土施工中,采用定型大钢模板与普通胶模板相结合的方式,能够达到预期的饰面设计效果;2)模板的设计和计算,符合规范要求,能够满足工程质量和安全要求,并且能兼顾经济适用性原则;3)模板的安装与控制是清水混凝土质量的关键施工步骤。

The type selection, design, installation and disassembling of the formwork of the fair-faced concrete of the underground structure of a project in Wuxi are presented. The practice shows that ： 1 ） The surface decoration effect ex- pected can be realized by using set steel formwork combined with rubber formwork. 2） The design and calculation of the formwork meets the requirements of relevant standards and meets the quality and safety requirements of the project. The formwork adopted is economic and appropriate. 3 ） The installation and control of the formwork are key procedures to guarantee the quality of fair-faced concrete.
