The invention discloses a concrete immersed tube joint construction method suitable for a shallow dry dock. The concrete immersed tube joint construction method comprises the following steps that a complete immersed tube joint pouring task is divided into two stages; wherein the first-stage pouring task at least comprises pouring of a bottom plate, a left side plate, a right side plate, a cross beam, a longitudinal beam and a box column, a first-stage pipe joint is defined after pouring is completed, and the quality upper limit constraint of the first-stage pipe joint is determined according to the designed water level of the shallow dry dock and the undocking requirement and the stress requirement of the first-stage pouring task; after the first-stage pouring task is completed, steel sealing doors are installed at the two ends of the first-stage pipe joint, the first-stage pipe joint is transported to a wharf in a floating mode, and a second-stage pouring task is conducted on the water surface; the second-stage pouring task at least comprises pouring of the sub-top plate, and if other structures which are not poured exist, supplementary pouring continues until a complete immersed tube joint is obtained. The method has the beneficial effects that the construction cost can be effectively reduced, and meanwhile, the inter-section sealing of the pipe sections is not influenced.

    本发明公开一种适用于浅干坞的混凝土沉管管节建造方法,包括以下步骤:将一个完整的沉管管节浇筑任务划分为两期;其中,第一期浇筑任务至少包括底板、左侧板、右侧板、横梁、纵梁以及箱柱的浇筑,浇筑完成后定义为一期管节,并根据浅干坞的设计水位,以及第一期浇筑任务的出坞要求和受力要求,确定一期管节的质量上限约束;第一期浇筑任务完成后,为一期管节的两端安装钢封门,并浮运至码头,在水面进行第二期浇筑任务;第二期浇筑任务至少包括子顶板的浇筑,若存在其他未完成浇筑的结构,继续补充浇筑,直至得到完整的沉管管节。本发明的有益效果是:能够有效降低工程造价,同时不影响管节的节间密封。
