River-adjacent-foundation-pit island-building cofferdam clay sealing construction method
The invention provides a river-adjacent-foundation-pit island-building cofferdam clay sealing construction method, and belongs to the technical field of river deep-foundation-pit project sealing. The river-adjacent-foundation-pit island-building cofferdam clay sealing construction method includes the steps of island building cofferdam construction, wherein a cofferdam is constructed outside a preset position of a foundation pit; clay sealing wall construction, wherein a clay sealing wall is constructed between a preset position of the foundation pit and the cofferdam; foundation pit excavation, wherein excavation is carried out at a preset position of the foundation pit to obtain the foundation pit; inner formwork supporting box hoisting, wherein a prefabricated inner formwork supporting box is hoisted to a preset position in the foundation pit, positioned and reinforced; bearing platform construction, wherein the foundation pit is subjected to pouring to obtain a bearing platform; and inner formwork supporting box disassembling, cofferdam disassembling and river cleaning. According to the construction method, as the clay sealing wall is arranged, the physical characteristics of high sealing performance and plasticity of clay are used, the sealing requirement of the river-adjacent bearing platform foundation pit is met, and the sealing effect of the foundation pit is achieved; and as the inner formwork supporting box is hoisted, it is guaranteed that construction of the deep foundation pit is safe and stable, and meanwhile the inner formwork supporting box can serve as a bearing platform formwork.
