桩柱一体化桥墩在道路改桥梁工程中的应用

Application of Integrated Pile Pier in Road Reconstructed to Bridge Project

详细介绍了深圳某道路工程在下穿既有快速路采用路基改为桥梁方案时,为减少开挖深度、减少支护的工程量、节约工程造价,在桥墩设计中采用桩柱一体化设计,并对需要注意的技术要点进行了论述。该方案对成桩垂直度有一定要求,且墩柱外露部分需采用钢护筒跟进方式保证外观质量,有关经验可供相关专业人员参考。

The scheme of a road project in Shenzhen when underpasses an existing expressway by roadbed reconstructed to bridge is introduced in detail.In order to decrease the excavation depth,reduce the amount of support work and save the engineering cost,the integrated pile pier design is used in the pier design and the technical essentials required for attention are discussed.The scheme has certain requirements on the vertical degree of built pile,and the exposed part of the pile is required to use the follow-up mode of steel casing in order to guarantee the appearance quality.The relative experience can be referred for the similar projects.
