Underwater independent foundation construction method under complex geological environment
The invention discloses an underwater independent foundation construction method under a complex geological environment, which relates to the technical field of independent foundation construction, and comprises the following steps: vertically sinking a prefabricated open caisson into the bottom of a preset water area, and removing obstacles from the bottom in the prefabricated open caisson to enable the prefabricated open caisson to sink to the upper surface of a target plane layer; and then an underwater concrete layer with the preset thickness is added into the prefabricated open caisson, the prefabricated pile body is placed into the prefabricated open caisson, the bottom end of the prefabricated pile body makes contact with the upper surface of the target plane layer, the upper end of the prefabricated pile body extends to the water surface, and after the underwater concrete layer is solidified to the preset solidification strength, the prefabricated open caisson is separated and detached. According to the method, the problem that underwater independent foundation construction is not easy to carry out in complex geological environments such as a hard riverbed protection bottom or a tunnel containing a river bottom in a traditional method can be solved, and a novel underwater independent foundation construction method is provided, so that a large water surface hoisting construction scheme can be safely and easily implemented.
本发明公开了一种复杂地质环境下的水下独立基础施工方法，涉及独立基础施工技术领域，包括：将预制沉井垂直沉入预定水域底部，对预制沉井内底部进行清障，使预制沉井下沉至目标平面层上表面，然后向预制沉井内部加入预定厚度的水下混凝土层，并将预制桩体放入预制沉井，使预制桩体底端与目标平面层上表面接触且上端延伸于水面上，待水下混凝土层凝固至预定凝固强度后，将预制沉井分离并拆卸。本发明的方法可以解决传统方法不易在有坚硬河床护底或含河底隧道等复杂地质环境下进行水下独立基础施工的难题，提出了一种新的水下独立基础施工方法，以此可安全、容易地实施大型水面吊装施工方案。
