An HDPE solution for the renewal of a collapsing culvert with a large-diameter
The corrugated galvanized sheet pipe situated in the bed of the Grande-Prairie stream demonstrated signs of default which caused the closing of the area where the pipe passes under the St-Philippe road. Ms. Johanne Desrosiers, Assistant of Technical services department at the city of Mascouche, needed to rapidly proceed to the replacement of the large-diameter culvert in order to reestablish the area’s circulation while assuring the water’s free drainage and the aquatic fauna’s free circulation towards the Mascouche River.
Due to its length, 35 m (115 ft), and its big diameter of 3300 mm (130 in), the replacement of the pipe by a large diameter HDPE pipe was selected. Using a conventional excavation method, these were installed in a trench 8 m (26 ft) deep by 18.2 m (59.7 ft) wide by Sintra Inc. This installation was a first for the contractor.
