ROAD WORKS, HYDRAULIC WORKS, AND SUBWAY WORKS FOR PLACE SAINCTELETTE, BRUSSELS (BELGIUM)
In this paper, a major underground project in Brussels, Belgium which involved the construction of a subway tunnel and two road tunnels is described. The geology of the area consisted of old alluvia deposits from the river senne. The subsoil conditions, high underground water level and proximity of buildings, necessitated deep trenching for the diagram walls, which were stored with bentonite slurry until the required depth was reached, when concrete was cast into reinforced cages in the trenches. To create the passage, three prefabricated tunnel elements were placed side by side and sunk into the canal. The elements were built in a dry dock about 300 metres from the immersing spot. Each tunnel element was equipped with floats, towed to the site and sunk into a trench excavated in the canal bottom. The immersed elements were connected to the tunnel structure, built in-situ, utilizing two 80 cm wide joint constructions. Each tunnel element rests on two supports, obviating the need for a final foundation layer. The project also involved major improvements to the hydraulic system, including diversory works to sewer pipes, and reinforcement of the quay walls. The French title of this paper is 'travaux routiers, hydrauliques et du metro place sainctelett, bruxelles (belge)'.
