Method for prefabricating pipe joints of immersed tube tunnel
The invention discloses a method for prefabricating pipe joints of an immersed tube tunnel. The method comprises the following steps that 1, steel bars are bound in a shallow dry dock, and the pipe joints are poured; 2, a steel end shell, a steel end sealing wall and a guiding device are arranged at the two ends of each pipe joint; 3, a waterproof layer of each pipe joint is constructed; 4, prefabricated plates are prefabricated in a prefabricated site beside an assembling platform; 5, a dock door is opened, the pipe joints are conveyed to the assembling platform in a floating mode, and a hoisting system is arranged on the assembling platform; 6, the prefabricated plates are hoisted to the corresponding positions of the pipe joints through the hoisting system; 7, the waterproof layers areapplied above the prefabricated plates; and 8, the pipe joints are dragged to designated positions for reassembling and then sinking. According to the method, the pipe joint floating process is shallow in draft depth, the temporary project is little, the dredging amount in water or dredging is not needed, the environment influence is small, and streamlined operation can be carried out.
本发明公开了一种沉管隧道管节预制方法，包括以下步骤：步骤一，在浅干坞内绑扎钢筋、浇筑管节；步骤二，在管节的两端均设置钢端壳、钢端封墙及导向装置；步骤三，施作管节的防水层；步骤四，同步在拼装平台旁的预制场地内对预制板进行预制；步骤五，打开坞门，将管节浮运至拼装平台处，拼装平台上设置有吊装系统；步骤六，通过吊装系统将预制板吊放至管节对应位置安装；步骤七，施作预制板上方的防水层；步骤八，将管节拖至指定位置进行舾装后沉放。本发明管节浮运过程吃水深度浅、临时工程少、水中疏浚量少或无需疏浚、环境影响小、可流水化作业。
