Method for encapsulating outer wall of large-diameter seawater pipeline
The invention discloses a large-diameter seawater pipeline outer wall encapsulating method, which comprises the following steps that: steel pipes are arranged on a concrete cushion layer in a pipe ditch after being assembled, a pipeline side wall template is provided with a split bolt, one end of the split bolt is connected to a back ridge of the template, and the other end of the split bolt is subjected to spot welding with the surfaces of the steel pipes; when the concrete encapsulation is poured in sections after rib binding and formwork erecting are completed, the total pouring height in the first stage does not exceed the limiting height h; after the concrete subjected to the first-time limiting pouring loses fluidity, residual concrete pouring is carried out, and the residual concrete is subjected to layered pouring. According to the method, the height of one-time pouring is limited, and the remaining concrete is poured in a layered mode, so that the large-diameter seawater pipeline is prevented from floating upwards, and the construction quality and safety are improved.
本发明公开了一种大直径海水管道外壁包封方法，钢管组对后置于管沟内的混凝土垫层上，管道侧壁模板设对拉螺栓，对拉螺杆一端连接于模板的背楞，另一端与钢管表面进行点焊；待绑筋及支模完成后将混凝土包封分段浇筑时，第一阶段浇筑总高度不超过限位高度h；第一次限位浇筑的混凝土失去流动性之后进行剩余混凝土浇筑，剩余部分混凝土采用分层浇筑。本发明通过限定一次浇筑的高度并将剩余混凝土分层浇筑，避免了大直径海水管道上浮，提高了施工质量及安全性。
