The 1km Mersey Gateway Bridge has opened to the public

The 1km Mersey Gateway Bridge is the centerpiece of the construction work across Halton, which lasts more than three and a half years. The Mersey Gateway Bridge connect the towns of Widnes and Runcorn that are near the neck of the Mersey estuary. The total length of this bridge is 2,248m. It is made up of two viaducts on either side of a 1km six-lane-cable-stayed span. On Saturday 14 October the bridge opened after a beautiful firework show. The structure of this bridge has a unique design whereby the 80m-high central pylon is shorter than the two outer pylons, which are 110m in the north and 125m in the south. More than 25,000 people from at least nine different countries have worked on this project. Using innovative smart road technology, the wider project features more than 9km of new roads, seven junctions and 12 new bridges as well as an integrated traffic control information system.

The geological conditions of the engineering can be terrifically complex, how to ensure the safety and the stabilization of the project in this case? The self drilling anchor system can be the best solution. The self drilling rock anchor is an important element of the flexible supporting system. It is suitable for the stratum that is compatible for pre-stressed anchor bolt. In loose strata, high pressure grouting can compensate for geotechnical defects, with the help of the self drilling anchor system, drilling is completed through grouting of surround rock disturbance part of effective reinforcement. This anchor system can be integrated with the function of drilling, grouting and anchoring. The installation and operation are very simple so that the construction time can be shortened, but the anchoring effect for the complex ground conditions can be ensured.
