新疆布尔津山口拱坝混凝土入仓方案选择与缆机应用

为解决布尔津山口水电站陡峻"V"型河谷常态混凝土高拱坝制冷混凝土的入仓问题,拟选了高门塔机和缆机入仓两个混凝土浇筑入仓方案,对两个方案的优缺点、可行性、经济性及运行使用等方面进行了分析比选,考虑了坝址区的地形地貌、气候风力温差、坝体温控施工对设备的入仓强度及保证率要求等因素,研究确定了双缆机入仓方案,解决了拱坝制冷混凝土的入仓问题。两年的运行使用实践证明,缆机是一种较好的入仓方式。

Placement Scheme Selection of Xinjiang Buerjin Mountain Arch Dam Concrete and Application of Cable Machine

To solve the refrigeration concrete warehousing problem of high arch dam normal concrete in steep V type valley for Buerjin Yamaguchi hydropower station, two schemes of concrete pouring warehousing (high gate tower crane and winch) are selected. And then two schemes of advantages and disadvantage, feasibility, economic and operational aspects are compared. Considering the influence of topography, climate, wind temperature, temperature control construction in dam area on the strength and guaranteed rate of warehousing equipment, it determines the dual cable machine warehousing solutions to solve the refrigeration concrete warehousing problem of arch dam. Two years of operation case proved that the cable machine warehousing is a better way.
