灌注桩以其施工工艺简单、桩位布置灵活及经济高效等特点,广泛应用于水利水电工程中。在江坪河水电站工程中,引水系统进水口采用抗滑型灌注桩、厂房安装场采用承载型灌注桩、瓦屋台采用锚固型灌注桩。详细介绍了不同地形、地质条件下不同形式灌注桩的施工技术,很好地解决了边坡抗滑、地基承载不足等技术难题,保证了工程安全。
Pouring pile is widely used in water conservancy and hydropower projects because of its simple construction technology, flexible pile layout and economic efficiency. In the project of Jiangpinghe Hydropower Station, anti-slip type bored piles are adopted for the water intake of the diversion system, and the load-bearing bored piles are used for the installation of the factory buildings. Anchored bored piles are used for the Wutai station. The construction techniques of different types of bored piles under different topography and geological conditions are introduced in detail, and the technical problems of skid resistance and insufficient foundation bearing are well solved so as to ensure the safety of the project.
