Secondary floating state pouring immersed tube with transverse span changing and floating transportation using method
The invention relates to a secondary floating pouring immersed tube with a variable transverse span and a floating transportation use method. The immersed tube comprises a large end and a small end, the transverse width of the cross section of the large end of the immersed tube is larger than that of the cross section of the small end of the immersed tube, the transverse width of the cross section of the small end of the immersed tube is gradually reduced from the middle to the end in the longitudinal direction of the immersed tube, and the immersed tube comprises a top plate, a bottom plate and a wall. And a to-be-poured layer is arranged above the first poured layer. By reserving the to-be-poured layer which is not poured, compared with a complete immersed tube structure, the secondary floating-state pouring immersed tube with the transverse span changing is lighter in weight, the needed 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, engineering investment can be saved, and the construction efficiency is improved. 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.
本发明涉及一种横向跨度变化的二次浮态浇筑沉管及浮运使用方法。沉管包括大端和小端，沉管的大端的横截面的横向宽度大于沉管的小端的横截面的横向宽度，沉管的小端的横截面的横向宽度沿沉管纵向从中部向端部逐渐缩小，沉管包括顶板、底板和墙体，顶板包括第一已浇筑层，第一已浇筑层上方具有待浇筑层。通过预留未浇筑的待浇筑层，使得横向跨度变化的二次浮态浇筑沉管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。
