Construction method of shaft type underground parking garage
The invention discloses a shaft type underground parking garage construction method, which belongs to the technical field of underground parking garage construction, and comprises the following steps: step S10, freezing a stratum by adopting a freezing method to form a frozen wall, pouring a locking opening at a wellhead, and maintaining; s20, a foundation pit is excavated in the space formed by the frozen wall, water is continuously filled into the foundation pit, the foundation pit is excavated to the designed depth under the waterflooding condition, and the horizontal plane is kept at the designed height in the excavation process; s30, a prefabricated steel reinforcement framework and a prefabricated formwork are placed in the foundation pit; s40, the wall concrete pouring pipe and the bottom plate concrete pouring pipe are lowered to the designed depth; s50, concrete is continuously poured into the space between the frozen wall and the formwork, and the supporting structure is poured to the designed pouring face elevation; s60, after the concrete reaches the design strength, water in the foundation pit is pumped and drained; the formed structure is good in integrity, high in construction safety, high in stratum adaptability and environmentally friendly.
本发明公开了一种井筒式地下停车库施工方法，属于地下停车库施工技术领域，包括：步骤S10：采用冻结法冻结地层形成冻结壁，在井口浇筑锁口并进行养护；步骤S20：在冻结壁形成空间内开挖基坑，并向基坑内不断充水，在淹水条件下挖至基坑设计深度，开挖过程中保持水平面处于设计高度；步骤S30：在基坑中放置预制的钢筋骨架和模板；步骤S40：下放墙体混凝土浇筑管和底板混凝土浇筑管至设计深度；步骤S50：向冻结壁与模板之间的空间连续浇筑混凝土，浇筑支护结构至设计的浇筑面标高；步骤S60：待混凝土达到设计强度后，抽排基坑内的水；本发明形成的结构整体性好、施工安全性高、地层适应性强且绿色环保。
