Underground powerhouse palisade crane beam rock bench structure and construction method
The invention discloses an underground powerhouse rock wall crane beam rock bench structure and a construction method, the underground powerhouse rock wall crane beam rock bench structure comprises an upper inflection point side wall, an inclined rock bench and a lower inflection point side wall, a horizontal rock bench for supporting a rock anchor beam concrete formwork is arranged between the inclined rock bench and the lower inflection point side wall, and the horizontal rock bench is used for bearing loads of steel bars and concrete during rock anchor beam pouring; under the condition of not changing the stress structure characteristics of the palisade crane beam, the restriction of palisade crane beam construction on excavation of the lower part of the underground powerhouse can be relieved by changing the inclined rock bench structure of the palisade crane beam, the excavation mode, the concrete pouring opportunity and other methods, the key line construction period of powerhouse construction is shortened, and the construction efficiency is improved. And the risk that the palisade crane beam cracks due to deformation of high side wall surrounding rock caused by premature pouring of the palisade crane beam is avoided.
本发明公开一种地下厂房岩壁吊车梁岩台结构及施工方法，包括上拐点边墙、斜岩台和下拐点边墙，所述斜岩台和下拐点边墙之间设有提供岩锚梁混凝土模板支撑的水平岩台，并用于承担岩锚梁浇筑期间钢筋及混凝土的荷载；本发明在不改变岩壁吊车梁受力结构特点的情况下，通过改变岩壁吊车梁斜岩台结构、开挖方式及混凝土浇筑时机等方法，可以解除岩壁吊车梁施工对地下厂房下部开挖的制约，缩短了厂房施工的关键线路工期，并避免了岩壁吊车梁过早浇筑而受到高边墙围岩变形引起岩壁吊车梁裂缝的风险。
