Construction method for immersed tube prefabrication and transportation
The invention relates to the field of immersed tube construction, and particularly relates to a construction method for immersed tube prefabrication and transportation. The construction method comprises the following steps that a lifting platform system for prefabricating an immersed tube is erected in the area near the installation position of the immersed tube in a riverway; the immersed tube is prefabricated on a lifting platform; the lifting platform descends, so that the immersed tube descends into water; and the immersed tube is transported to the installation position of the immersed tube in a floating mode. According to the lifting platform system for immersed tube prefabrication, the lifting platform for prefabricating the immersed tube is arranged in the riverway, so that the occupied area caused by immersed tube prefabrication is greatly reduced, foundation pit supporting and anti-seepage treatment are not needed, the early-stage cost is greatly saved, and then the cost of the whole immersed tube prefabrication construction is reduced; and the prefabrication position is located in the area near the installation position of the immersed tube, so that the engineering quantity for dredging a channel is greatly reduced, and the corresponding construction cost is greatly reduced.
本发明涉及沉管施工领域，特别是一种用于沉管预制及出运的施工方法，包含以下步骤：在河道中沉管安装位置附近的区域搭设用于预制沉管的升降平台系统；在所述升降平台上预制所述沉管；下降所述升降平台，使所述沉管下降入水；将所述沉管浮运至所述沉管安装位置。本申请所述的一种用于沉管预制的升降平台系统，用于预制沉管的升降平台在河道内，大大减少预制沉管造成的占地，也不用基坑支护及防渗处理，大大节约了前期成本，进而降低了整个沉管预制施工的成本，而且预制位置位于沉管安装位置附近的区域，大大减少了对航道进行疏浚的工程量，也大大降低了对应的施工费用。
