Ground anchor press-in type open caisson method
The invention discloses a ground anchor press-in type open caisson method. The open caisson method comprises the following steps that a pressure-bearing bracket is installed on the wall of an open caisson; a ground anchor is installed; a downward pressing assembly is installed, the downward pressing assembly is installed with the pressure-bearing bracket and the ground anchor, and the downward pressing assembly is configured to enable the open caisson to sink; the open caisson sinks; after the open caisson sinks to a preset elevation, the downward pressing assembly is removed from the pressure-bearing bracket, and a supporting piece is arranged between the pressure-bearing bracket and the ground anchor in a cushioned mode; the open caisson is heightened; and after the open caisson is heightened, the pressure-bearing bracket is removed from the wall of the open caisson, and the supporting piece is moved away. According to the open caisson method, the pressure-bearing bracket abuts against the ground anchor, so that extra supporting force is provided for the open caisson in the process of heightening the open caisson, the stability coefficient of the open caisson in the heightening process is improved, the risk of sudden sinking of the open caisson when the geology is soft is avoided, meanwhile, the segmentation frequency of the open caisson can be reduced, the construction progress is accelerated, and the construction cost is reduced.
本申请公开了一种地锚压入式沉井方法。沉井方法包括如下步骤：在沉井的井壁安装承压牛腿。安装地锚。安装下压组件，下压组件分别与承压牛腿和地锚安装，下压组件配置成可使得沉井下沉。令沉井下沉。在沉井下沉至预设标高后，将下压组件从承压牛腿拆除，在承压牛腿和地锚之间垫设支撑件。接高沉井。在接高沉井后，将承压牛腿从井壁拆除，将支撑件移走。本申请的沉井方法通过使承压牛腿抵在地锚上，实现了在接高沉井的过程中对沉井提供了额外的支撑力，提高了沉井在接高过程中的稳定系数，规避了地质较软时出现沉井突沉的风险，同时可减少沉井的分节次数，从而加快了施工进度，降低了施工成本。
