Open caisson blade foot and open caisson construction operation method for advanced grouting of blade foot
The invention discloses an open caisson blade foot which comprises a blade foot body, the contact face of the blade foot located on the lower portion of an open caisson and a soil body is an inclined section, a telescopic grouting pipe is arranged in the blade foot, and meanwhile, the invention discloses an open caisson construction operation method matched with the open caisson blade foot for advanced grouting of the blade foot. A soil body in the open caisson is excavated, and secondary grouting is carried out on super-settlement or obvious inclined settlement so as to solve the problems that in the open caisson construction process, the well wall inclination is too large, the soil body is unstable, and the underground soil body is damaged. According to the operation method, sinking of the open caisson is more uniform, sudden sinking can be avoided, potential safety hazards are eliminated, sinking balance of the open caisson is facilitated, and the construction efficiency is improved.
本发明公开了一种沉井刃脚，包括：刃脚本体，位于沉井下部的刃脚与土体接触面为一倾斜截面，且刃脚内部设置有可伸缩注浆管，同时公开了与之配合使用的刃脚超前注浆的沉井施工作业方法，通过提前注浆，稳定下沉，挖开沉井内部土体对“超沉”或明显倾斜沉降进行二次注浆来解决沉井施工中易产生井壁倾斜过大、土体失稳、井下土体破坏等问题。本作业方法使沉井下沉更加均匀，可避免突沉产生，消除安全隐患，且有助于沉井的下沉平衡，提高施工效率。
