Construction method of steel box girder type single-tower single-cable-plane cable-stayed bridge
The invention discloses a construction method of a steel box girder type single-tower single-cable-plane cable-stayed bridge. The construction method comprises the following steps that firstly, a cast-in-place concrete box girder section is poured; secondly, a cable crane is installed; thirdly, a main cable tower and a stay cable laying device are installed; 4, hoisting a main beam section of the steel box and arranging stay cables; 5, side span and main span ballasting construction is carried out; sixthly, the hoisting equipment is dismantled; in the fourth step, the main beam section of the steel box is hoisted in a segmented mode, stay cables are arranged, the main beam section of the steel box is divided into a plurality of beam sections, hoisting is carried out one by one, and the corresponding stay cables are arranged. Compared with a construction method of a traditional steel box girder type cable-stayed bridge, the construction method has the advantages that potential safety hazards of construction of the main beam section of the steel box can be effectively reduced and the mounting precision can be improved by replacing a truck crane, a crawler crane and a full framing with the cable crane, and the construction cost can be effectively reduced by combining the cast-in-place concrete box girder and the steel box girder.
本发明公开了一种钢箱梁式独塔单索面斜拉桥施工方法，包括如下步骤：步骤一：现浇砼箱梁段的浇筑；步骤二：缆索吊的安装；步骤三：主索塔及斜拉索布设装置的安装；步骤四：钢箱主梁段的吊装及斜拉索的布设；步骤五：边跨和主跨压重施工；步骤六：吊装设备的拆除；所述步骤四中，对钢箱主梁段进行分段吊装及斜拉索的布设，将所述钢箱主梁段拆分为若干梁段并逐一进行吊装及对应斜拉索的布设。本发明与传统钢箱梁式斜拉桥的施工方法相比，利采用缆索吊替代汽车吊、履带吊、满堂支架的方式能够有效降低钢箱主梁段施工的安全隐患并提高安装精度，且以现浇砼箱梁与钢箱梁的结合的方式能够有效降低施工成本。
