Construction method and structure of immersed tunnel by utilizing gravity type crimping
The invention relates to a construction method and structure of an immersed tube tunnel using gravity type crimping, and the construction method comprises the following steps: excavating an immersed tube tunnel foundation trench, installing an immersed tube in the immersed tube tunnel foundation trench, and marking the immersed tube as an installed immersed tube; a sealing gasket is arranged at the end of the installed immersed tube or the end of the next immersed tube in advance; sinking the next immersed tube until the hinge rotating part at one end of the next immersed tube is connected with the hinge fixing part at one end of the installed immersed tube; the immersed tube continues to sink, the hinge rotating part rotates around the hinge fixing part, the next immersed tube rotates and sinks under the action of gravity, the sealing gasket generates compression deformation, and then sealing is achieved; marking the next immersed tube as an installed immersed tube; and by parity of reasoning, the next immersed tube is constructed until the construction is finished. The sealing device has the beneficial effect that a good sealing effect can be achieved under the conditions of shallow water and insufficient water pressure in areas with small water pressure.
本发明涉及一种利用重力式压接的沉管隧道的施工方法及结构，包括以下步骤：开挖沉管隧道基槽，在沉管隧道基槽内安装沉管，将其标记为已安装沉管；在已安装沉管或下一根沉管的端部预先设置密封垫圈；下沉下一根沉管，直至该下一根沉管一端的铰链转动部与已安装沉管一端的铰链固定部相连；继续下沉该沉管，使铰链转动部绕铰链固定部旋转，在重力作用下该下一根沉管转动下沉，使得密封垫圈产生压缩变形，进而实现密封；将该下一根沉管标记为已安装沉管；以此类推，施工下一根沉管，直至完工。本发明的有益效果为：能在浅水和水压较小区域水压力不足的情况下实现良好的密封效果。
