新型沉箱吊具的设计

Design of new caisson lifting device

目前在沉箱吊装施工中,大多采用人工穿销工艺。人员需要高空和潜水作业,效率低、安全风险大。为简化施工,设计一种可以利用吊船索具钩实现自动开合的沉箱吊具及其吊点,并应用到实际工程中,现已完成了200余次吊装施工。可显著提高效率、降低风险、节约成本。

When lifting a reinforced concrete caisson, inserting and pulling pins are usually implemented bythe manpower, and aerial ＆ diving operation are needed, which is characterized by low efficiency and great danger.To simplify the construction, we design a new lifting point and sling which can fix and unhook by controlling therigging hook and used in practice for more than 200 lifting operations.It is more efficient while reduces the risk andcost significantly.
