消能防冲桩板联合施工技术

Energy Dissipation Anti-Scour Sheet PileCombined Construction Technology

为高效完成江坪河水电站河道消能防冲工程,通过方案优化和比选,提出采用“上部宽竖井+下部圆形桩”相结合的防冲桩板联合施工技术,将常规防冲桩板施工工序由原来的四序施工变为两序施工,取得了缩短施工工期、保障施工安全、提高工程质量的效果,证实了该施工工艺的可行性,对类似工程项目提供借鉴和参考经验。

In order to efficiently complete the river course energy dissipation anti-scourproject of Jiangpinghe Hydropower Station,through scheme optimization and comparison,the anti-scoursheet pile combined construction technology of“upper wide vertical shaft+lower round pile”is proposed to change the conventional anti-scoursheet pile construction processes from previously four-process construction to two-process construction,which achieves the effect of shortening the construction period,ensuring construction safety and improving the project quality,andconfirmsthe feasibility of this construction process,thus providing reference and experience for similar engineering projects.
