某体育场变截面倾斜清水混凝土结构施工技术

Construction of Inclined Fair-faced Concrete Structure with Variable Cross-section in a Stadium

某体育场工程结构复杂,变截面倾斜构件多,施工难度大,通过清水混凝土技术在该工程中的成功应用,总结了变截面倾斜清水混凝土结构施工技术的施工难点、设计方案和施工技术措施及注意要点,并成功开发了对拉螺栓孔堵头以及改进型模板内支撑,对类似的变截面倾斜清水混凝土结构的施工有很好的借鉴意义。

A stadium is a complex structure, which has plenty of variable cross-section with inclined components, so the construction is very difficult. With the successful application of fair-faced concrete, a conclusion has been obtained which includes the difficulties, the designs, the measures and the cautions of variable cross-section inclined components based on fair-faced concrete. Moreover, the plug of split bolt has been successfully developed as well as the improvement of the internal support, which has a significant influence on similar fair-faced concrete construction of variable cross-section inclined components.
