Segmented prefabrication method of immersed tube joints
The invention relates to the technical field of immersed tube tunnel construction, in particular to a segmented prefabrication method of immersed tube joints.The prefabrication period of a single tubejoint can be remarkably shortened, the prefabrication cost of a single joint cannot be increased greatly, a reinforcement cage or tube joints cannot be frequently jacked or cannot frequently ascend and descend in the prefabrication link, the waiting period that the tube joints reach the strength required by moving can be shortened, the number of times of moving is obviously reduced, the crack control difficulty can be reduced easily, the forming quality of immersed tubes is improved, and then the engineering quality is improved. Meanwhile, through the arrangement of a steel bar binding area and a pouring area and matching of the reciprocating moving positions of bed-jigs and a formwork in the method, the occupied area of the prefabrication area of a single tube joint is compact, multipleprefabrication assembly lines can be arranged in a width-limited site easily, arrangement of a prefabrication factory is facilitated, a hoisting system does not need to be erected in the moving process of the reinforcement cage, the bed-jigs and the formwork, safety is good, construction is convenient, and the construction period can be further shortened easily.
本发明涉及沉管隧道施工技术领域，特别涉及一种沉管管节的分段预制方法，能够显著缩短单个管节的预制周期，且不会大幅增加单个关节的预制成本，在预制环节不会频繁顶推、升降钢筋笼或管节，也能够减少管节达到移动所需强度的等待期，移动次数明显减少有利于降低控裂难度，提高沉管的成型质量，进而提升工程质量，同时，本方法的钢筋绑扎区和浇筑区的布置及胎架、模板往复移动位置的配合，使得单个管节的预制区域占地面积紧凑，有利于在宽度有限的场地内设置多个预制流水线，便于预制工厂的布置，钢筋笼、胎架及模板的移动过程中均无需架设吊装系统，安全性好，施工方便，进一步利于缩短工期。
