Large-diameter open caisson casing pipe and large-diameter vertical shaft construction method
The invention discloses a large-diameter open caisson casing pipe and a large-diameter vertical shaft construction method.The large-diameter open caisson casing pipe comprises a first-section casing pipe and a plurality of standard section casing pipes, the standard section casing pipes are connected in a nested mode, the standard section casing pipes and the first-section casing pipe are connected in a nested mode, and the first-section casing pipe and the standard section casing pipes are each of a double-layer structure. The single-layer casing pipe hole forming technology has high lateral pressure resistance and can bear large-diameter and large-depth water and soil pressure, and therefore the limitation that a traditional single-layer casing pipe hole forming technology is limited by the diameter of 7 m or below and deep digging cannot be achieved can be broken through.
本发明公开一种大直径沉井套管及大直径竖井施工方法，该大直径沉井套管包括首节套管及多节标准节套管，所述标准节套管之间以及所述标准节套管与首节套管之间相互嵌套连接，其中首节套管和标准节套管均为双层结构。本发明有较强的抗侧压能力，能够承受大直径、大深度的水土压力，从而可以突破传统单层套管成孔工艺受直径7m以下和无法深挖的限制。
