A3 Hindhead Tunnel bang on target for early opening! |



|
So how do they get the tunnels in the right place and to meet in the middle? Around 15 years ago a network of survey stations were established in the area for the planned A3 improvements and these were linked to the Ordnance Survey grid. To check these existing stations, and establish new ones necessary for the road works, they will be using the Global Positioning System (GPS). This uses the same satellites as a car navigation system, but that is where the similarity ends. The GPS receivers are set on our survey stations for at least one hour to record their position. The results are processed later to give at least centimetre accuracy as opposed to the 5 to 10 metres obtained from car systems. Four permanent survey “monuments” have been established in this way at each end of the tunnel. From these positions we will then establish more survey stations around the tunnel entrance and eventually inside the tunnel. The most advanced (the one nearest the tunnel face) station are used to control the tunnel excavation. |
|
The tunnel guidance system consists of a robotic theodolite which will be orientated by sighting back down the tunnel, taking readings on the previous survey stations and then tracking targets on the tunnel excavator. This tells the excavator operator his position in real time and so where to dig. In this way they control the tunnel alignment. |

Sometimes only a picture can get our attention! |



|
The Honda rider was travelling at approximately 85 mph.
The VW driver was talking on a mobile phone when she pulled out from a side street, apparently not seeing the motorcycle.
The riders reaction time was simply not sufficient enough to avoid this accident. |
|
The car had two passengers |
|
All three involved (two in the car & the bike rider) were killed instantly. |

STOP Talking & or Texting on Mobile phones whilst trying to drive.

We make no apologies for these graphic pictures because WE HAVE ALL DONE IT! |

The Volkswagen actually flipped over from the force of impact |
