常庄干渠高架桥斜波腹板钢混组合梁顶推施工

On incremental launching method of corrugated steel web reinforced concrete box girder at main canal viaduct in Changzhuang

以陇海路常庄干渠高架桥为例,通过分析工程概况及施工特点,确定了多点连续顶推法施工方案,对顶推预制平台施工、波形钢腹板导梁、定位安装、PC组合箱梁预制、顶推等施工工艺作了阐述,为同类工程施工提供了依据。

Taking the main canal viaduct of Changzhuang along Lanzhou-Lianyungang Railway as the example, the paper analyzes the engineering survey and construction features, identifies multiple continuous incremental launching method construction scheme, and illustrates the incremental launching platform construction, corrugated steel web guide beam, positions and installment, PC box-girder forecasting, and incremental launch- ing, so as to provide some reference for similar projects.
