Damming deep foundation pit supporting structure
The invention relates to the field of deep foundation pit supporting, in particular to a damming deep foundation pit supporting structure. The damming deep foundation pit supporting structure realizes treatment of a soft underlying layer, reduces the influence of eccentric load, supports horizontal load in a construction period and performs water diversion and flow guiding in a later operation period. The damming deep foundation pit supporting structure comprises an open caisson section and an empty box buttress section arranged on a top plate of the open caisson section; the empty box buttress section comprises a retaining wall internally provided with an empty box and a buttress structure arranged on the side face of the retaining wall; and the buttress structure faces the horizontal load direction. When a foundation pit is treated in the construction period, open caisson is adopted for treating the soft underlying layer foundation, and therefore large vertical supporting loads and certain horizontal supporting loads can be provided. Safety risks of the foundation pit can be effectively controlled, and investment is saved. The structure is particularly suitable for deep foundation pit supporting design of a hydropower station water inlet and the like needing an operation period flow guiding function.
本发明涉及深基坑支护领域，尤其是一种筑实现对软弱下卧层的处理，减小偏心荷载的影响，从而对施工期水平荷载进行支护，并且在后期的运行期引水导流的筑坝深基坑支护结构，包括沉井段以及设置于沉井段的顶板上的空箱扶壁段，所述空箱扶壁段包括内设有空箱的挡墙以及设置于挡墙侧面的扶壁结构，所述扶壁结构朝向水平荷载方向。在施工期进行基坑处理时，采用沉井对软弱下卧层地基进行处理，从而可提供较大的竖向支撑荷载和一定的水平向支撑荷载。本发明可有效的控制基坑安全风险，节约投资。本发明尤其适用于水电站进水口等需要具备运行期导流功能的深基坑支护设计之中。
