Soil-taking-free open caisson and sinking construction method thereof
The invention relates to the technical field of soil-taking-free open caisson construction, in particular to a soil-taking-free open caisson and a sinking construction method thereof.The soil-taking-free open caisson comprises a well wall, a blade foot, a well wall injection system and a blade foot injection system, the blade foot is fixed to the bottom end of the well wall, and a plurality of first injection holes are formed in the blade foot; a plurality of first injection holes are formed in the well wall, the blade foot injection system is communicated with the first injection holes so as to inject water into the soil body through the first injection holes, a second injection hole is formed in the well wall, and the well wall injection system is communicated with the second injection hole so as to inject a resistance reducing medium into the soil body through the second injection hole. The invention aims to provide a soil-sampling-free open caisson and a sinking construction method thereof in order to solve at least one technical problem in the background technology.
本申请涉及免取土沉井施工技术领域，具体而言，涉及一种免取土沉井及其下沉施工方法，包括井壁、刃脚、井壁注射系统和刃脚注射系统，所述刃脚固定在所述井壁的底端，在所述刃脚布置有多个第一注孔，所述刃脚注射系统与各所述第一注孔连通，以通过各所述第一注孔向土体注水，在所述井壁上形成有第二注孔，所述井壁注射系统与所述第二注孔连通，以通过所述第二注孔向土体喷注降阻介质。本申请的目的在于针对背景技术中所述的至少一个技术问题，提供一种免取土沉井及其下沉施工方法。
