The invention discloses a method for salvaging a large bottom supporting plate integrally descending into the river in a blocking mode. The large bottom supporting plate is partitioned; all the blocksare spliced together through the connecting structures and then connected with the large steel structure into a whole, stable self-floating of the large steel structure is achieved after the large steel structure enters water, connection with the large steel structure is cut off, the splicing structures between all the blocks are snapped through the self-weight of the large bottom supporting plate, and the large bottom supporting plate is automatically blocked and salvaged underwater. According to the method, large salvage equipment and diver operation are not needed, rapid recycling and cyclic utilization are achieved, high safety and economical efficiency are achieved, labor investment and working hours are reduced, construction cost investment is effectively reduced and the construction period is shortened.
本发明公开一种大块底托板整体下河分块打捞方法,大块底托板进行分块,各块通过连接结构拼接在一起,然后与大型钢结构连接成为一体,下水后待大型钢结构实现平稳自浮,切断与大型钢结构的连接,利用大块底托板的自重拉断各块之间的拼接结构,实现大块底托板在水下自动分块并打捞。本发明无需大型打捞设备以及潜水员作业,实现快速回收,循环利用,具有较高的安全性以及经济性,并且降低人工投入和工时,有效减少施工成本投入和缩短施工工期。
