The invention relates to an immersed tube gravel foundation bed leveling, transporting and sinking integrated ship and an immersed tube tunnel construction method, and belongs to the technical field of immersed tube tunnel construction. The integrated ship for leveling, transporting and sinking the immersed tube gravel foundation bed comprises a single ship body, a leveling device, an immersed tube hoisting device and cantilever beams arranged in pairs, the cantilever beams arranged in pairs are symmetrically arranged on the two sides of the single hull in the width direction, the cantilever beams extend out from the single hull to the outer side of a ship side in a cantilever mode in the width direction of the single hull, and a pair of cantilever beams is arranged close to a bow and a stern of the single hull respectively. The leveling device is carried on the single ship body and located between the two pairs of cantilever beams, and the leveling device can turn over in the vertical plane relative to the single ship body so as to be switched between the working state and the non-working state. The immersed tube hoisting device comprises sinking devices which are arranged in one-to-one correspondence with the cantilever beams, and the sinking devices are installed on the cantilever beams. The integrated ship integrates the functions of gravel foundation bed leveling and immersed tube transporting and sinking, and can transport immersed tubes with the width close to the upper limit of the passing width of an inland waterway.
本发明涉及一种沉管碎石基床整平和运输沉放一体船及沉管隧道施工方法,属于沉管隧道施工技术领域。该沉管碎石基床整平和运输沉放一体船,包括单船体、整平装置、沉管吊放装置和成对设置的悬挑梁;成对设置的悬挑梁对称设置于单船体宽度方向的两侧,悬挑梁沿单船体的宽度方向自单船体向船舷外侧悬挑伸出,靠近单船体船艏和船艉分别设置有一对悬挑梁;整平装置搭载于单船体上并位于两对悬挑梁之间,整平装置可相对于单船体在竖直面内翻转以在工作状态和非工作状态之间转换;沉管吊放装置包括与悬挑梁一一对应设置的沉放设备,沉放设备安装于悬挑梁。该一体船集碎石基床整平和沉管运输沉放功能于一体,可运输宽度接近内河航道通行宽度上限的沉管。
