Open caisson method and open caisson structure
The invention provides an open caisson construction method and an open caisson structure, and relates to the field of open caisson construction.The top of a bidirectional jack is connected with a pipe joint column, and a steel corbel is erected on the pipe joint column and serves as an important guide component in the open caisson sinking process; according to the open caisson, soil in a foundation pit in a space defined by the steel structure columns can be continuously excavated, meanwhile, the lowermost steel corbel A erected on the pipe section columns is dismantled, and then the open caisson can sink to the position where a steel corbel B on the upper portion of the steel corbel A is erected on the pipe section columns by means of the gravity of the open caisson. Besides, in the descending process of the open caisson, if the open caisson inclines, the height of the pipe joint column can be adjusted through the jack, so that it is guaranteed that the open caisson is always kept in the vertical state in the descending process, the perpendicularity and stability in the descending process of the open caisson are effectively controlled, construction is facilitated, the construction risk is reduced, and cost is saved.
本发明提供了一种沉井施工方法及沉井结构，涉及沉井施工领域，通过双向千斤的顶部连接管节柱，所述钢牛腿架设于所述管节柱上，作为沉井下沉过程中的重要导向构件，当需要沉井下沉时，可以将所述钢结构柱所围成的空间内的基坑内的土不断挖除，同时拆除架设于所述管节柱上的最下部的钢牛腿A，然后沉井可以依靠自身的重力下沉至钢牛腿A上部的钢牛腿B架设于所述管节柱上的位置。另外，在沉井下降的过程中，如果发生倾斜，可以通过千斤顶对的管节柱高度进行调节，从而保证沉井下降的过程中始终保持垂直状态，从而有效控制沉井下降过程中的垂直度与稳定性，方便施工并降低施工风险，节约成本。
