Construction method of bridge foundation and deepwater prefabricated structure
The invention relates to a construction method of a bridge foundation and a deepwater prefabricated structure. The deepwater prefabricated structure comprises a caisson and a bearing platform, and a first channel is formed in the top of the caisson; the bearing platform is connected to the top of the caisson and covers the first channel, and a second channel penetrating through the bearing platform is formed in the bearing platform; the first channel, the second channel and the inner cavity of the caisson are communicated and jointly form a working channel used for construction, and a blade foot at the bottom of the caisson is matched with a foundation. During use, drilling piles do not need to be inserted and driven into the foundation, and the foundation without a covering layer cannot be damaged; construction can be conducted on the top of the bearing platform, and constructors do not need to be located in the caisson. In the early stage of construction, the deepwater prefabricated structure serves as a construction platform and provides a mounting position for a cleaning device; and when the bridge foundation is poured after cleaning, the deepwater prefabricated structure serves as a pouring formwork for pouring. In the later period of construction, the deepwater prefabricated structure and the concrete poured in the deepwater prefabricated structure form a bridge foundation which serves as a part of the bridge foundation, material waste is avoided, and construction steps are reduced.
本申请涉及一种桥梁基础的施工方法及深水预制结构，包括沉箱和承台，其中沉箱的顶部设有第一通道；承台连接在沉箱的顶部，并覆盖于第一通道上，承台上开设有贯穿其的第二通道；以及第一通道、第二通道和沉箱的内腔连通，并共同形成用于施工的工作通道，沉箱底部的刃脚与地基相适配。在使用时，不需要插打钻孔桩，不会破坏无覆盖层的地基；在承台顶部就可进行施工，施工人员不需要位于沉箱中。在施工前期，深水预制结构作为施工平台，为清理装置提供安装位置；清理后进行浇筑桥梁基础时，深水预制结构作为浇筑模板，进行浇筑。在施工后期，深水预制结构和其内灌注的混凝土形成桥梁基础，作为桥梁基础的一部分，避免材料浪费，减少施工步骤。
