Flat ground pipe section prefabricating device and method
The invention provides a flat ground pipe section prefabricating device and method. A flat ground pipe section prefabricating field is built and comprises a near-shore flat ground prefabricating field and a plurality of land area flat ground prefabricating fields which are connected and arranged in parallel; a shoreside winch provides vertical shoreline horizontal power for a pipe section on a near-shore flat ground prefabricating field, under the cooperation of a hydraulic spherical bearing support at the bottom of the near-shore flat ground prefabricating field, after the pipe section prefabricated on the near-shore flat ground prefabricating field slides to a horizontal table along a sliding track beam, the pipe section and a bottom steel plate slide into water, and then the pipe section is fixed on a bottom steel plate. The immersed tube sliding into the water is transported to a tunnel site through a tugboat; and after the winch on the shore slides the pipe sections on the land area flat ground prefabricating field on the inner side to the near-shore flat ground prefabricating field, the steps are repeated, and pipe section prefabricating streamlined operation is formed. A large temporary foundation pit does not need to be excavated beside a water area to serve as an immersed tunnel pipe section prefabricating site, the method is different from a conventional method that water injection floating transportation pipe sections are conducted after a large foundation pit is excavated in a dry dock, the construction cost is low, the construction period is short, and application and popularization of the immersed tunnel are facilitated.
本发明提供了一种平地管段预制装置及方法，搭设平地管段预制场，包括近岸平地预制场和若干个相连且平行设置的陆域平地预制场；岸边的卷扬机给近岸平地预制场上的管段提供垂直岸线水平动力，在近岸平地预制场底部的液压球形轴承支座的配合下，在近岸平地预制场预制完成的管段沿滑移轨道梁滑移至入水平台后，管段和底钢板滑移入水，滑入水中的沉管通过拖船运输至隧址；岸边的卷扬机给内侧陆域平地预制场上的管段滑移至近岸平地预制场后重复上述步骤，形成管段预制流水化作业。本发明无需在水域旁开挖大型临时基坑作为沉管隧道管段预制场地，区别常规干坞开挖大型基坑后注水浮运管段，工程造价低，工期短，有利于沉管隧道的使用和推广。
