Construction method for dismantling pivot cofferdam
The invention provides a construction method for removing a pivot cofferdam, and belongs to the technical field of hydro-junction construction. The invention provides a construction method for dismantling a cofferdam unit, which specifically comprises the steps of dismantling an upper structure, excavating and dredging earthwork between walls, and dismantling an underground diaphragm wall comprising an overwater part and an underwater part by adopting a rope saw process, and further provides a construction method for dismantling a pivot cofferdam, which comprises the steps of dividing the cofferdam unit and dismantling the cofferdam unit. According to the construction method for dismantling the pivot cofferdam, the difficulty in dismantling the diaphragm wall of the cofferdam with high strength, high steel content and high underwater volume is effectively overcome, and the work of segmenting, hoisting and dismantling the diaphragm wall segmenting block with the maximum single block of about 126 tons is successfully completed; newly-built and already-built buildings and structures are protected, continuous navigation and non-navigation-closure construction is achieved, and wide application prospects are achieved.
本发明提供了一种枢纽围堰拆除的施工方法，属于水利枢纽施工技术领域。本发明提供了一种围堰单元拆除的施工方法，具体包括上部结构拆除，开挖并疏浚墙间土方，采用绳锯工艺拆除包括水上部分和水下部分的地连墙，还提供了一种枢纽围堰拆除的施工方法，包括划分围堰单元和围堰单元拆除。本发明所述枢纽围堰拆除的施工方法，有效克服了高强度、高含钢量、高水下体量的围堰地连墙拆除的困难，成功完成最大单块约126吨的地连墙分割块的分割，吊装和拆除工作；保护了新建、已建建筑物和构筑物，且实现了不断航、不封航施工，具有广阔的应用前景。
