Immersion construction system and immersion construction method of semi-suspension type cofferdam
The invention discloses a sinking construction system and a sinking construction method of a semi-suspended cofferdam, and relates to the field of deepwater pier bearing platform foundation construction.The system comprises the cofferdam and a plurality of guide piles located in the cofferdam, the guide piles are vertically installed, one or more guide piles close to the upstream of the cofferdam are provided with lifting mechanisms, and the lifting mechanisms are arranged on the guide piles close to the upstream of the cofferdam. The output end of the lifting mechanism is connected with the bottom of the upstream of the cofferdam, and lifting force exists between the lifting mechanism and the bottom of the upstream of the cofferdam. The upstream side of the cofferdam is connected with the guide piles through the lifting mechanism, a semi-suspension system is formed, the influence of the height difference of the mud surfaces at the upstream and downstream positions of the cofferdam on the posture of the cofferdam is effectively solved, and unbalanced resistance in the sinking process of the cofferdam is balanced through the lifting mechanism and the water adding amount into the cofferdam.
本发明公开了一种半悬挂式围堰的沉放施工系统及沉放施工方法，涉及深水桥墩承台基础施工领域，系统包括围堰和位于围堰内的多个导向桩，导向桩竖直安装，存在一个或多个且靠近围堰上游的导向桩上设置有提升机构，所述提升机构的输出端与围堰上游的底部连接，并且提升机构与围堰上游的底部之间存在提升力。本发明通过提升机构将围堰上游侧与导向桩连接，形成半悬挂体系，有效解决围堰上游、下游处的泥面高差对围堰姿态的影响，通过提升机构及向围堰内的加水量来平衡围堰下沉过程中不平衡的阻力。
