Fabricated open caisson construction device and method
The invention discloses a fabricated open caisson construction device and method, and relates to the technical field of open caisson construction. The fabricated open caisson construction device comprises a sinking control device and a pre-stressed anchor bar, the pre-stressed anchor bar is used for being pre-buried in a prefabricated pipe piece, and the sinking control device is used for being connected with the pre-stressed anchor bar so as to lift or press the prefabricated pipe piece. According to the fabricated open caisson construction device provided by the embodiment of the invention, during construction, the sinking control device is connected with the pre-stressed anchor bars in the prefabricated pipe pieces, so that the vertical displacement of the well wall structure can be restrained, and the sinking opportunity, the single-time sinking amplitude and the sinking speed of the well wall can be actively adjusted and accurately controlled; the purpose of adjusting the sinking coefficient of the open caisson in the sinking process is achieved, the problems of sudden sinking, blocking and the like of the open caisson are effectively solved, and the sinking stability of the open caisson is improved.
本申请公开了一种装配式沉井施工装置及方法，涉及沉井施工技术领域。该装配式沉井施工装置，包括下沉控制装置和预应力锚筋，所述预应力锚筋用于预埋在预制管片内，所述下沉控制装置用于与所述预应力锚筋连接以提拉或下压所述预制管片。本申请实施例提供的装配式沉井施工装置，在施工时，通过将下沉控制装置与预制管片内的预应力锚筋连接，能够约束井壁结构的竖向位移，实现井壁的下沉时机、单次下沉幅度、下沉速度的主动调节和精确控制，达到调节沉井在下沉过程中的下沉系数的目的，有效解决沉井“突沉”、“卡顿”等问题，提高了沉井下沉的稳定性。
