Double-wall steel jacket box cofferdam implantation construction method
The invention relates to a double-wall steel jacket box cofferdam implantation construction method which comprises the following steps: under a ballasting condition, horizontally lowering a bottom section by utilizing a hanging system until the bottom section is in contact with the relatively high side of an implantation section riverbed, and completing the construction of a first stage; and increasing the weight of the end, making contact with the riverbed, of the bottom section, adjusting the bottom section through the hanging system, so that the bottom section sinks horizontally till the bottom section is horizontally implanted into the riverbed, and completing second-stage construction. Batch sinking is adopted for bottom section implantation, batch sinking is serious, under the action of a hanging system, the bottom section sinks slowly through unbalanced weight on the bottom section and by means of tidal changes, the higher side of a riverbed is pressed, end resistance and side friction resistance of the riverbed to a bottom section blade foot are overcome, meanwhile, the hanging system is used for resisting upstream and downstream unbalanced buoyancy, and therefore the bottom section is made to sink slowly. Stable implantation under the conditions of tides and uneven riverbeds is realized.
本申请涉及一种双壁钢套箱围堰着床施工方法，其包括以下步骤：在压重条件下，利用吊挂系统水平下放底节，直到所述底节与着床段河床相对较高的一侧接触，完成第一阶段的施工；增加所述底节与河床接触的一端的压重，并利用所述吊挂系统对所述底节进行调整，以使所述底节水平下沉，直到所述底节水平着床，完成第二阶段施工。底节着床采用分批次下沉、分批次严重，在吊挂系统作用下，通过对底节的不平衡压重，并借助潮汐变化，使底节缓慢下沉，采取对河床较高一侧进行压重，克服河床对底节刃脚的端阻力及侧摩阻力，同时利用吊挂系统抵抗上下游不平衡浮力，实现了在潮汐以及河床不平情况下的稳定着床。
