Open well sinking device, open well structure and open well sinking method
The invention relates to the technical field of open caisson, and discloses an open caisson sinking device, an open caisson structure and an open caisson sinking method. According to the open caisson structure, through the functional layer, the metal blade foot and the open caisson structure, by means of the synergistic effect of a self-loaded space attitude control system, the self weight of the open caisson can be correspondingly reduced, and the wall thickness of the open caisson can be correspondingly reduced; the dragging force in loading is more used for enhancing the soil body cutting sinking effect of the metal blade foot, and the control of the sinking posture is more accurate. Due to the fact that the well wall of the open caisson body and the frame structure are manufactured on the ground and integrally formed through one-time pouring, the well wall of the open caisson body can directly serve as an outer wall of a basement, and the frame structure serves as a supporting system of a basement main body structure. The vertical accurate butt joint of the stress center of the frame column of the main body structure and the pressure-bearing center of the corresponding foundation pile required by civil building design is ensured.
本发明涉及沉井技术领域，公开了一种沉井下沉装置、沉井结构和沉井下沉方法，本发明中，通过千斤顶利用基桩摩擦力使管节对沉井本体加载下沉，本沉井结构通过功能层、金属刃脚以及沉井结构利用自身加载的空间姿态控制系统的协同作用，可相应减轻沉井自重和减小壁厚，利用金属刃脚的踏面远小于传统刃脚踏面，使得加载中的拖拽力更多地用于增强金属刃脚的土体切割下沉效果，下沉姿态的控制更为精准。由于沉井本体的井壁与框架结构在地面上制作并一次浇注整体成型，使得沉井本体的井壁可直接作为地下室的外墙，框架结构则作为地下室主体结构的支撑体系，确保了民用建筑设计所要求的主体结构的框架柱受力中心与对应基桩承压中心竖向准确对接。
