Tunnel construction method for short-tube-joint immersed tube
The invention belongs to the technical field of immersed tube engineering, and specifically provides a tunnel construction method for a short-tube-joint immersed tube. The tunnel construction method comprises the following steps: S10, performing assembly line type prefabricating production on the immersed tube, wherein the production comprises concrete pouring which is once forming, and length ofthe formed immersed tube is 20-30m long; S20m transferring the immersed tube onto a semi-submersible barge through a plurality of trolleys, wherein the length direction of the immersed tube is a forward direction thereof, the length direction of the immersed tube is perpendicular to the forward direction of the semi-submersible barge, and depth of immersion of the semi-submersible barge is smallerthan or equal to 3m; and S30, transporting the immersed tube to an immersed tube diving region through the semi-submersible barge, adopting an engineering barrage to pull and position the immersed tube, and adopting a hydraulic crimping method to accomplish underwater butt-joint of adjacent two immersed tubes. The tunnel construction method can effectively simplify barging mounting operation of the immersed tube, reduces construction difficulty, improves operation efficiency, is convenient for quality control of the immersed tube, and ensures tunnel construction quality.
本发明属于沉管工程技术领域，具体提供一种短管节沉管隧道施工方法，包括步骤：S10、对沉管进行流水线式预制生产，包括混凝土浇筑，其中，所述混凝土浇筑为一次成型，成型后的沉管的长度为20‑30m；S20、通过若干台车将沉管移运至半潜驳上，其中，沉管的长度方向为其前进方向，且沉管的长度方向与所述半潜驳的前进方向相垂直，所述半潜驳的吃水深度小于等于3m；S30、通过所述半潜驳将沉管运输至沉管下潜区，采用工程驳船进行对所述沉管的牵引及定位，采用水力压接法完成相邻两沉管之间的水下对接。本发明可以有效简化沉管的上驳安装操作，降低施工难度并提高作业效率，并且便于沉管的质量管控，确保隧道施建质量。
