The salvage airbag is used to provide buoyancy for the transportation and buoyancy of the box culvert, so as to realize the installation and construction. Compared with the traditional floating crane installation and construction technology, less large-scale equipment is invested, the cost is low, and the construction cost is reduced.
Utilize the characteristics of the flexibility and buoyancy of the salvage airbag to assist the box culvert in the offshore transportation and installation. During installation, adjust the inflation and deflation of the airbag to control the floating and sinking of the box culvert. The operation is simple and the construction quality is reliable.
The construction of this technology is not restricted by narrow sea areas, and it can be used for construction when large floating cranes cannot enter the site. Through rigorous mechanical checking and engineering practice, the construction technology of airbag-assisted installation of box culverts will be promoted from theory to practice, and a new construction method will be provided for similar engineering construction in the future.
