The proposed solution consists of the execution in each one of the meetings of 4 stakes nailed in ductile iron of the type BDP Ø170 / 10,6 mm, to execute with a slope of 10º with respect to the vertical, being the interior of the tube filled with concrete of the class C 25/30. Regularization of the foundations with the possible reorganization of the surface layers and replacement by better quality soils (technical landfills - as defined in the Specific Charges of the EP). Cleaning of the water-line bed to guarantee continuity of the surface water system using mechanical means, including removal, replacement and compaction, leaking of leftover products, and possible damages for deposit, to an extent of about 10.00 Meters for each side.
