Open caisson sinking device and construction method thereof
The invention relates to the technical field of open caisson, and particularly discloses an open caisson sinking device and a construction method thereof, the device comprises a limiting baffle ring, a supporting ring assembly, a height adjusting mechanism and an anti-sinking plate, an embedded part is arranged at the top end of an open caisson body, and the limiting baffle ring is detachably connected to the top end of the open caisson body through the embedded part; the open caisson body is slidably sleeved with the supporting ring assembly, and the top end of the supporting ring assembly abuts against the bottom end of the limiting baffle ring. The height adjusting mechanisms are arranged in the circumferential direction of the open caisson body at equal intervals and used for adjusting the positions of the supporting ring assemblies and guiding the supporting ring assemblies. The anti-sinking plate is of an annular structure and arranged on the outer side of the open caisson body in a sleeving mode, a gap is formed between the anti-sinking plate and the open caisson body, and the height adjusting mechanism is arranged at the top end of the anti-sinking plate. The sinking speed and the sinking distance of the open caisson body can be controlled, and the conditions of sudden sinking, super sinking and the like are avoided.
本发明涉及沉井技术领域，具体公开一种沉井下沉装置及其施工方法，装置包括限位挡环、支撑环组件、高度调节机构和防陷板，沉井本体的顶端设置有预埋件，限位挡环通过预埋件可拆卸连接在沉井本体的顶端；支撑环组件滑动套设在沉井本体上，且支撑环组件的顶端与限位挡环的底端抵接；高度调节机构沿沉井本体的周向等间距设置，高度调节机构用于调节支撑环组件的位置，并对支撑环组件进行导向；防陷板为环形结构，防陷板套设在沉井本体的外侧，且与沉井本体之间设置有间隙，高度调节机构设置于防陷板的顶端。本发明可实现对沉井本体的下沉速度及下沉距离进行控制，避免出现突沉、超沉等情况。
