Brokk Robotic Demolition & Concrete Bursting in Weymouth, Dorset
In recent years, global warming has been causing concern for coastal cities and towns. Bad weather brings heavy seas and storm water from inland. Most coastal towns were established around estuaries. A recipe for disaster, unless serious flood and tide control measures are in place. Weymouth has flood defences in place, but the city is aware of the need for expansion and reinforcement of these measures.
Marine and coastal engineering produces robust structures. The sea is a tough customer, so piers, harbour walls and tidal barriers are built to withstand everything from the constant tidal fluctuations to the less subtle ravages of winter storms and high seas which seem to be increasing in ferocity. Augmenting or replacing flood and tidal defences often means removing existing structures either partially or entirely.
24-7 Diamond Drilling and Sawing Services has been involved in demolition for 25 years. We use Brokk remote control demolition equipment for most of our work. These small, remote controlled, tracked vehicles can climb stairs, make their way over awkward obstacles and access confined areas. The range of available attachments makes them incredibly versatile.
For breaking up large concrete structures like pylon foundations, sea walls, piers and dams, we turn to concrete bursting equipment. This involves drilling a 112mm bore into the structure and inserting a probe equipped with hydraulic rams. When the rams are deployed, the structure cracks in to manageable chunks. With this technique, we are able to break structures up to five metres thick.
Weymouth Brokk Robotic Demolition & Concrete Bursting Case Study
Brief: 24-7 Diamond Drilling & Sawing Services Limited were contracted to carry out a concrete bursting job where flood control barriers were removed and replaced due to erosion.
Solution: Being strong enough to hold back the sea meant the barriers were very thick. Concrete bursting was the quickest and easiest solution. Time once again was paramount, once the structures had been broken to a more manageable size they were then craned away onto a lorry for disposal. Enabling the next crew to come in and make good the structure.
