The Vietnam Road Administration has just approved a plan to spend more than VND9 billion to salvage Phong Chau Bridge and the vehicles involved in the bridge collapse on September 9.
The Phong Chau bridge collapsed on the Tam Nong district side.
Accordingly, the project to overcome the consequences of natural disasters at Phong Chau bridge will be implemented under an emergency order with a provisional budget of 9.13 billion VND from the State budget.
This fund is spent on the salvage of the bridge and sunken vehicles, as well as on traffic diversion, traffic safety, and staffing. The Vietnam Road Administration assigned the Phu Tho Provincial Department of Transport to be the project implementation unit, to carry out procedures for appointing contractors, and to manage the project's progress and quality.
Previously, the Vietnam Road Administration also received a report on the construction plan to salvage the collapsed bridge. Specifically, sunken vehicles located outside the steel truss span will be immediately salvaged, brought closer to shore and lifted into the staging area by a 150-ton specialized crane.
For vehicles stuck in the steel truss that cannot be salvaged immediately, the construction unit will use a 400-ton crane on shore and 2 ships equipped with salvage equipment to lift the steel truss out of the water and cut each span.
The tugboat will bring each steel truss span to shore and use a specialized 150-ton crane on shore to lift, lift, and place it in the staging area. During the process of cutting the steel truss spans, the construction unit will also simultaneously take out the vehicles stuck inside and tow them to shore.
With steel truss spans and vehicles buried deep under layers of sand and silt, the construction unit will use hoses and suction to remove the sand and silt before salvage.
For the concrete bridge deck, piers, piles, and submerged abutments, the contractor will use a 400-ton crane on shore and two ships equipped with salvage equipment to lift them to the water surface. The concrete will be demolished by an excavator equipped with a concrete chisel on board.
For the collapsed T7 bridge pier, it cannot be demolished or towed, so the Vietnam Road Administration has not calculated the cost of handling it. For now, the specialized agency will drop buoys to warn of waterway traffic safety, and when the water recedes, they will survey and find a way to demolish it.
