Abstract

The invention discloses a block-by-block salvage method for a large bottom supporting plate in the river as a whole. The large bottom supporting plate is divided into blocks, and each block is spliced ​​together through a connecting structure, and then connected with a large steel structure to form a whole. The structure realizes stable self-floating, cuts off the connection with the large steel structure, uses the self-weight of the large bottom supporting plate to break the splicing structure between each block, and realizes the automatic division and salvage of the large bottom supporting plate underwater. The invention does not need large-scale salvage equipment and divers to operate, realizes rapid recovery and recycling, has high safety and economy, reduces labor input and working hours, effectively reduces construction cost input and shortens construction period.

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...
