摘要
针对坝址区气候寒冷、河谷狭窄陡峻及高地应力等特点,为保证工程施工进度、确保工程质量开展了多项关键技术研究,如拱坝建基面合理开挖形式、边坡坝段无盖重固结灌浆、埋管法接触灌浆、夏季封拱灌浆以及坝后反拱型水垫塘等多项关键技术研究,在此基础上采用了多项新工艺、新方法,有力地保证了工程质量、进度。
In order to meet the requirements on construction schedules and keep the quality of construction of Laxiwa Hydropower Station, some key technologies are studied after considering the characteristics of cold climate, narrow and steep river valleys and high ground stress and others in dam site, such as excavation method of arch dam foundation, no cover-weight consolidation grouting of abutment sections, pipe guiding contact grouting, closure grouting in summer and counter-arched type cushion pool. On this basis, many new techniques and methods are used and the construction quality and process are ensured.
