溪洛渡水电站左岸地下厂房蜗壳混凝土施工技术

摘要

溪洛渡水电站左岸地下主厂房蜗壳混凝土施工具有工期紧、施工强度高、难度大、制约因素多、技术要求高等特点,针对这些特点,在总结、借鉴以往施工经验的基础上,对左岸地下厂房蜗壳混凝土施工技术进行了一些创新和改进,摸索出一套成熟的蜗壳混凝土施工技术措施和施工组织管理经验,从施工规划、混凝土浇筑施工、接触灌浆施工、温度控制等方面进行介绍,供其他工程参考.%The concrete construction for spiral case in left-bank underground powerhouse of Xiluodu Hydropower Station is restricted by short period, high strength, high difficulty, more constraints and high technical requirements. For dealing with the construction problems, some construction technologies are innovated or improved, and the construction management is also improved. The concrete construction is introduced herein from the aspects of construction planning, concrete pouring, contact grouting and temperature control.
