卡拉贝利水利枢纽工程闸井混凝土浇筑方案比选

Comparison and selection of gate shaft concreting schemes for Kalabeili Hydraulic Complex

结合新疆卡拉贝利水利枢纽工程闸井混凝土施工工期要求、施工场地条件,对塔机+吊罐入仓、溜槽入仓及混凝土泵泵送入仓等3种大体积混凝土浇筑入仓方式可行性及优缺点进行了分析比较。结果:混凝土泵车浇筑入仓方式优越,推荐采用,实施后,顺利完成了闸井混凝土浇筑任务,效益显著。

For the gate shaft concreting of Kalabeili Hydraulic Complex, taking into consideration the construction period and field conditions, the feasibility, advantages and disadvantages of three mass concrete placing schemes were compared, including tower crane and bucket scheme, chuting scheme and concrete pump scheme. The con- crete pump scheme was recommended. Gate shaft concreting was completed smoothly with the selected scheme.
