The pile-drilling work is coming to an end: Tonight (from Tuesday to Wednesday) the first of the five drilling rigs currently deployed on site is to be transported to a new site. The remaining four rigs are to remain on site until the pile-drilling work is complete. These drilling rigs are being used to stabilize the ground with reinforced concrete piles so that the accelerator facility FAIR can be built.

 

More than 80 percent of the total of 1,350 drilled piles has already been put in place. As the construction work progresses and more piles are drilled, the area on which the remaining piles are to be set decreases in size. This means that there is not enough space for five of these gigantic rigs on the area still to be worked – which is why the first drilling rig is being transported to a new site.

 

Given its weight of around 100 tonnes and its dimensions, the transfer of the giant drilling rig qualifies as an abnormal load. In accordance with German road traffic regulations such transportation requires special approval. As abnormal loads would disrupt the normal flow of traffic, these may only be conducted at times when the volume of traffic is low. The load also has to be accompanied by the police.

 

Following the conclusion of the pile-drilling work in the coming months, the other drilling rigs deployed on site will be transported to new construction sites. FAIR will provide information on the dates for the transport of these abnormal loads.
