Perfect preparation of the tunnelling work is an absolute must
For the client EnBW, meeting deadlines is at the top of the list of priorities. A number of challenges need to be overcome to ensure that the mining work starts on time. PORR project manager Torsten Schmuck: "We have to plan and organise up to four parallel tunnelling works in a complex system of tunnels, shafts and caverns. Occupational safety is also a high priority. That's why we are setting up a rescue service with our own construction site personnel, who can act safely and quickly in the event of danger in the mountain. In addition, the permits for residential and blasting facilities as well as water permits are associated with considerable effort."
Protecting people and nature takes priority in all work
On the five construction sites, the work is focussed on setting up the construction site and creating the tunnel cuts. Excavators will be used to loosen the loose rock in the pre-cut, after which the areas in the rock will be demolished by blasting. At the works site (construction site 1), PORR is securing a slope under the passing federal roads B462 with jetcrete and soil nails. The main access tunnel to the cavern is being constructed from this construction site. In the slope areas to the north and south of the Schutter tunnel (construction site 2), safety nets and fences are being installed to secure the rock. The material produced during the work in the mountain will later be removed through this tunnel. Noise barriers will minimise the impact on local residents.
The necessary clearing work at the two access tunnels Murgwerk (construction site 4) and Schwarzenbachwerk (construction site 5) was already carried out during the winter period, meaning that excavation and stabilisation work will begin here shortly. In order to protect flora and fauna, they were accompanied by ecological construction supervision. "The location in the upper Murg Valley in the middle of this unique Black Forest region, which is worthy of protection, requires that the impact on the environment and nature, especially the River Murg, is kept to a minimum," explains Schmuck.
