Baukau Tunnel Ruhrgebied

ruhrgebied2

At the A43 / A42 freeway junction in Herne, the approx. 550 m long Baukau Tunnel is being built. Our customer is BeMo Tunneling. A total of 70 wells (30 infiltration wells and 40 extraction wells) are being drilled for dewatering. The wells are drilled with a bore diameter of 750 mm and extracted with a diameter of 315 mm. We rent a 100 ton Delmag RH30 drilling machine. The water is pumped from 25 m deep vacuum wells into infiltration wells, also 25 m deep, back into the ground.
