Bridge demolition FAQ
How do you demolish a bridge?
Bridge demolitions are some of the most technical demolitions undertaken. They require significant care to ensure minimal debris escapes onto roads or property. A concrete bridge can be demolished by hammering it into the ground, or panellised and moved away in pieces. Sometimes shielding may be placed beneath the bridge so that concrete debris does not fall into a waterway or onto traffic below.
There are four common bridge demolition methods – explosives, hydraulic breakers, dismantling and bursting. Boreholes may be used to insert explosives which can be effective at taking down large amounts of concrete. Dismantling involves cutting a bridge into sections and removing them with a crane. Bursting offers advantages as it is a relatively quiet bridge demolition technique which uses pressure to force the concrete to split and break. The use of hydraulic breakers for bridge demolition creates a lot of noise, debris, dust and vibrations.
Why do you need to demolish a bridge?
As the capacity of highways are reached, partial or total removal of bridges may be necessary to allow for expansion of the highway beneath or for widening of the bridge itself. The structure being removed is usually in close proximity to other structures and in the direct vicinity of travellers which calls for extra caution during the bridge demolition planning and execution.
Why is engineering needed for bridge demolition?
Extensive structural analysis goes into the removal sequence that forms a key part of bridge demolition. The structure must be checked for strength and stability at every step as the structural system, loads and load path will change. The removal of lateral bracing between girders is an important part of the demolition operation. The engineer needs to analyse and define how many braces can be safely removed at any given time. All the important information must be clearly presented in demolition plan drawings to be used in the field.
What is a bridge deck?
A bridge deck is the portion of a bridge that acts as the roadway to support vehicular or pedestrian traffic. Deck types are generally defined by the materials from which they are made and they way they are fitted together.
Concrete bridge decks are flat roadway surfaces made of poured concrete. Thin steel beams are laid into the concrete to provide strength and flexibility. Reinforced bridge decks are similar, with interwoven steel support bars. A reinforced bridge deck may also incorporate solid steel sheets laid beneath the concrete to offer additional relief from the pressure of weight. A pedestrian bridge is commonly constructed from wood, with metal support systems to reinforce the strength of the material on the deck.
