The invention relates to an immersed tube transporting and sinking barge and an immersed tube transporting and sinking construction method, and belongs to the technical field of immersed tube tunnel construction. The immersed tube transporting and sinking barge comprises a single ship body, cantilever beams arranged in pairs and an immersed tube hoisting device. The cantilever beams arranged in pairs are symmetrically arranged on the two sides of the single hull in the width direction, and 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. At least two pairs of cantilever beams are symmetrically arranged relative to the central surface of the length direction of the single ship body; the immersed tube hoisting device comprises immersed devices which are arranged in one-to-one correspondence with the cantilever beams, the immersed devices are installed on the cantilever beams, and the immersed devices are jointly connected with immersed tubes located below the single ship body so as to transport the immersed tubes and control immersed installation of the immersed tubes; wherein the sinking devices corresponding to the cantilever beams arranged in pairs are correspondingly connected with the two sides of the sinking pipe in the width direction respectively. The width of the immersed tube transported by the immersed tube transportation immersion barge can be close to the upper limit of the passing width of an inland waterway, and the width of the inland waterway can be fully utilized.
本发明涉及一种沉管运输沉放驳及沉管运输沉放施工方法,属于沉管隧道施工技术领域。该沉管运输沉放驳包括单船体、成对设置的悬挑梁,以及沉管吊放装置;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;悬挑梁至少为两对且相对于单船体长度方向的中心面呈对称设置;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上,各沉放设备共同连接位于单船体下方的沉管,以运输沉管并控制沉管的沉放安装;其中,成对设置的悬挑梁所对应的沉放设备分别对应连接沉管宽度方向的两侧。该沉管运输沉放驳运输的沉管宽度可接近内河航道通行宽度上限,能够充分利用内河航道宽度。
