Construction method for fabricated traffic bridge at flood discharge hole
The invention discloses a flood discharge hole fabricated traffic bridge construction method, which adopts a curved bridge straight construction mode for construction, and comprises the following steps: 1) constructing a bridge abutment and a bridge pier; the abutment construction comprises the steps of abutment foundation excavation, anchor rod construction, foundation pouring construction, abutment body pouring construction, abutment cap pouring construction and abutment back backfilling; in the abutment back backfilling step, backfilling operation is carried out in two construction periods, and in the first construction period, an abutment body is constructed to the flood season water level elevation; in the second construction period, after abutment body construction is completed, abutment back backfilling is conducted on the portion, above the flood season water level elevation, of the abutment body; (2) constructing a bent cap; (3) prefabricating the T-shaped beam; according to the construction method, for a special construction scene of the position of the flood discharge tunnel in the flood discharge system of the hydropower station, special environment factors of the construction scene site are fully considered, normal construction of the traffic bridge under the conditions of the flood season and the rainy season can be well guaranteed, and the requirements for the construction period and progress of the traffic bridge are guaranteed.
本发明公开了一种泄洪洞口装配式交通桥施工方法，采用弯桥直做的方式进行施工，包括以下步骤：1）桥台、桥墩施工；桥台施工包括桥台基础开挖、锚杆施工、基础浇筑施工、台身浇筑施工、台帽浇筑施工和台背回填的步骤；在台背回填步骤中分两个施工期进行回填操作，第一个施工期为将台身施工至汛期水位高程；第二个施工期为台身施工完成后，对台身位于汛期水位高程以上的部分进行台背回填；2）盖梁施工；3）T梁预制施工；4）桥面施工。本发明施工方法针对水电站泄洪系统中泄洪洞所处位置的特殊施工场景，充分考虑施工场景现场的特殊环境因素，能够很好地保证在汛期以及雨季的情况下对交通桥的正常施工，以保证交通桥施工周期和进度的要求。
