钢筋桩是龙滩水电站左岸高边坡开挖超前支护的重要手段,必须在边坡马道出露下一坡面开挖之前完成,单根长度为25～30米,按常规拼装费工费时,施工场地狭窄,吊装难度大,其工期紧、要求高。我们通过重点研究影响钢筋桩施工工艺的两个重要工序——钢筋对接方法和钢筋笼吊装方法,采取有针对性的施工技术措施,确保了钢筋桩施工质量和施工进度满足设计的要求。
Reinforced concrete piles are an important means of advanced support for high slope excavation on the left bank of Longtan Hydropower Station and must be completed before the next slope excavation of the roadside is exposed. The single length is 25-30 meters, , Narrow construction site, lifting difficult, the tight schedule, demanding. We focus on the two important processes that affect the construction process of reinforced concrete piles - the steel docking method and the lifting method of steel cages, and take targeted construction techniques and measures to ensure that the quality of the construction of steel piles and construction schedule to meet the design requirements.
