| 摘要： | Get water moving up to twice the speed of sound and you can smash through concrete with it and this technology is playing a vital role in a highway improvement project along one of the busiest roads in the West Midlands. Jets of water travelling at supersonic speeds are blasting concrete from around bearings beneath two flyovers on the A4440 Southern Link Road near Worcester. The hydrodemolition project on the A4440 is being led by Aquaforce Concrete Services, working for its parent company, the civil and structural engineering specialist Freyssinet. It is carrying out concrete repairs on the existing roadway on behalf of main contractor Alun Griffiths (Contractors) Ltd. Worcestershire County Council is overseeing the £62m scheme to upgrade a 3.5-mile section of the link road connecting the M5 with south and west Worcester, Great Malvern, Ledbury, Upton and Herefordshire. |
