Abstract

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.

Description

technical field [0001] The invention belongs to the field of bridge construction, and in particular relates to a block-by-block salvage method for a large bottom supporting plate to be lowered into the river as a whole when the large-scale steel structure airbag method is lowered into the river. Background technique [0002] In bridge construction, in order to quickly construct long-span high-pile cap foundations across rivers and other deep waters, large-scale steel cofferdams have also become a common measure for the construction of pier caps in water. , the bottom support plate becomes a necessary auxiliary measure. The bottom support plate plays a great role in the smooth operation of the airbag and the force transmission. Sometimes underwater cutting is required, the recycling cost is high or cannot be recycled, and the cost of the bottom pallet itself is not low, resulting in relatively high construction costs. Contents of the invention [0003] The present inventio...
