The invention provides an assembly type underground garage construction method. An assembly type underground garage comprises a steel open caisson housing sinking to the designed elevation through a well sinking technology, a top plate, a bottom plate and a steel structure garage, the top plate and the bottom plate are poured on the top and the bottom of the steel open caisson housing, the steel structure garage is erected in the open caisson, the steel open caisson housing is divided in the vertical direction into multiple steel open caisson housing unit segments, each segment steel open caisson housing unit is internally provided with a steel support, each steel open caisson housing unit and the corresponding steel support form a standard module assembled on a factory prefabricated site,steel pipe pile columns capable of achieving guide and supporting are arranged in the steel open caisson housing units and the steel supports of the standard modules in a penetrating manner, a steelbeam is erected above the standard modules, a jack is used for pressing down the standard modules to be in place one by one, the standard modules are welded to form a whole body, the steel structure prefabricating assembling and open caisson construction manner is adopted, the integrated underground garage can be efficiently, rapidly and precisely built, the whole structure is stable, the steel pipe pile columns can be directly used for assisting supporting, building materials can be saved, and the influence on the surrounding can be reduced.
本发明提供一种装配式地下车库施工方法，其装配式地下车库包括采用沉井工艺下沉到设计标高的钢沉井外壳、浇筑于钢沉井外壳顶部、底部的顶板和底板，以及搭设于沉井内部的钢结构车库，钢沉井外壳沿竖向分割为若干钢沉井外壳单元节段，每节段钢沉井外壳单元内具有钢支撑，沉井外壳单元与钢支撑为工厂预制现场装配的标准模块，标准模块的钢沉井外壳单元及钢支撑内贯穿有实现导向和支撑的钢管桩柱，在标准模块上方架设钢梁利用千斤顶将标准模块逐个下压到位并焊接形成整体，本发明采用钢结构预制组装、沉井施工方式，能高效、快速、精准的建设一体式地下车库，整体结构稳定，直接利用钢管桩柱进行辅助支撑，节省了建材，减少了对周围环境的影响。
