Secondary floating state pouring type immersed tube structure and secondary floating state pouring method
The invention relates to a secondary floating state pouring type immersed tube structure and a secondary floating state pouring method. A secondary floating state pouring type immersed tube structure comprises a top plate, a bottom plate and a wall body, the top plate comprises a first poured layer and a to-be-poured layer, and the to-be-poured layer is located above the first poured layer. The poured first poured layer can be matched with the bottom plate and the wall body to form a stable structure, and the stable structure can be kept during floating transportation, that is, the unpoured layer to be poured does not affect the floating transportation safety; by reserving the to-be-poured layer which is not poured, compared with a complete immersed tube structure, the secondary floating state pouring type immersed tube structure has the advantages that the weight is lighter, the required draft is shallower during floating transportation, floating transportation is easier, the safety of floating transportation is improved, excavation deepening of a river below a floating transportation line can be reduced, the project investment can be saved, and the construction cost is reduced. And a complete top plate is formed after the to-be-poured layer is subjected to secondary floating state pouring, so that the quality safety of the immersed tube used in the foundation trench can be ensured.
本发明涉及一种二次浮态浇筑式沉管结构及二次浮态浇筑方法。一种二次浮态浇筑式沉管结构，包括顶板、底板和墙体，所述顶板包括第一已浇筑层和待浇筑层，所述待浇筑层位于所述第一已浇筑层上方。已浇筑的第一已浇筑层能够配合底板和墙体形成一个稳定的结构，能够在浮运时保持稳定，即未浇筑的待浇筑层不会影响浮运安全；通过预留未浇筑的待浇筑层，使得二次浮态浇筑式沉管结构相比于完整的沉管结构的重量更轻，在浮运时所需吃水更浅，浮运更加容易以及提高了浮运的安全性，且能够减小对浮运线路下方的河流的开挖加深，能够节约工程投资，且对待浇筑层二次浮态浇筑后形成完整的顶板，能够保证基槽内使用的沉管质量安全。
