摘要
以宁波市轨道交通L3一期儿童公园站为施工背景,介绍大于75 m超深地下连续墙铣接法关键施工技术。施工过程中,通过对泥浆护壁质量、成槽精度和混凝土首灌量3个方面的控制,保证地下连续墙的质量,为以后类似超深地下空间围护结构施工提供技术经验。
Based on the construction background of Children's Park Station of Ningbo Rail Transit L3(Phase I), the key construction technology of more than 75 m deep underground continuous wall milling method is introduced. During the construction process, the quality of the underground continuous wall is ensured by the control of the mud wall quality, the groove precision and the first volume of the concrete. The technical experience is provided for similar construction of super-deep underground space envelope enclosure.
