Formwork support construction method for unilateral wall of underground structure of nuclear power station
The invention discloses a nuclear power station underground structure unilateral wall formwork supporting construction method which comprises the following steps: after a shaping formwork is erected, a prefabricated lattice type steel column leans against a main back ridge of the shaping formwork; the bottom of the lattice steel column passes through a cone pre-buried on a bottom plate guide wall or an H-1 shaft wall body which is constructed on the previous layer, and the top of the lattice steel column extends out of a pull rod through a cone pre-buried in an area which is not covered by a waterproof coiled material on a backfill body, then penetrates through a channel steel strap and is fastened through a pull rod pressing plate and a butterfly nut; and the channel steel straps, the lattice type steel columns and the typified formworks form an integral supporting system. According to the method, the overall supporting strength is high, the rigidity is large, deformation is not prone to occurring, the wall can be poured to the set elevation in a formwork erecting mode at a time, construction layer sections are reduced, the construction time of construction joint treatment, repeated formwork erecting and disassembling and waterproof roll construction is effectively shortened, meanwhile, the concrete pouring speed can be increased, and the overall construction period is shortened; and the size of the concrete wall body after construction can meet the quality requirement.
本发明公开了一种核电站地下结构单侧墙体模板支撑施工方法，在定型模板支设完成后，将预制完成的格构式钢柱靠在定型模板主背楞上，格构式钢柱底部通过设置在底板导墙上或前一层施工完成的H‑1轴墙体上预埋的锥体、顶部通过回填体上防水卷材未覆盖区域预埋的锥体引伸出拉杆，然后穿过槽钢背带，利用拉杆压板和蝶形螺母进行紧固，将槽钢背带、格构式钢柱、定型模板形成整体支撑体系。该方法支撑整体强度高、刚度大，不易变形，能够实现墙体一次可支模浇筑至既定标高，减少了施工层段，有效减少了施工缝处理、重复支拆模板、防水卷材施工时间，同时可提高混凝土浇筑速度，缩短整体施工工期，而且可保证施工后混凝土墙体的尺寸满足质量要求。
