苏州北互通跨河段现浇箱梁施工工艺

Construction technology of cast-in-place box beam in river-crossing section of interchange in north of Suzhou

探讨了苏州北互通跨河段现浇箱梁的施工工艺,对比分析了钢管桩支撑和木桩承台支撑钢管桩两种方案的优缺点,并根据实际情况,采用木桩承台作为桥式支架临时墩承重结构,以达到降低工程成本、快速、方便的目的。

The construction technology of cast-in-place box beam in river-crossing section of interchange in north of Suzhou is discussed. The advantages and disadvantages of shoring system of steel-pipe pile and wood pile platform are comparatively analyzed. According to practical situations the latter-wood pile platform is adopted as temporary bracing structure for bridge in order to reduce engineering cost and limit time.
