Large open caisson sinking construction method
The invention relates to the field of open caissons, in particular to a large open caisson sinking construction method which comprises the steps that an open caisson body is arranged; the open caisson body sinks; the peripheral soil body in the soil body structure in the open caisson body is dug out, and the open caisson body continues to sink; wherein a soil body structure in the open caisson body is excavated from the periphery and then from the center, the excavated soil body structure is transported to the outside of the open caisson body, the central soil body is slit under the extrusion action of a frame beam of the open caisson body structure and collapses, and the open caisson body continues to sink. The large-diameter open caisson construction method has the effect that the center soil body can be conveniently taken out during large-diameter open caisson construction.
本申请涉及沉井领域，尤其是涉及一种大型沉井下沉施工方法，其包括设置沉井本体；使沉井本体下沉；将沉井本体内的土体结构中的外围土体挖出，沉井本体继续下沉；其中，先四周后中心挖取沉井本体内的土体结构，并将挖取的土体结构运输至沉井本体外，中心土体受沉井本体结构框架梁的挤压作用被分切而坍塌，沉井本体继续下沉。本申请具有在大直径沉井施工时，便于中心土体取出的效果。
