📋 Tender Overview
Benefit of safety conditions and availability and reliability of the railway infrastructure.
The work of stabilization of landfill slope located at km 122600 of the Douro line in the municipality of Sabrosa were completed.
The slope adjacent to the Regua Dam Albufeira presented signs of erosion and instability associated with an ineffective drainage of the left side excavation slope with potential impact on rail exploration.
The endeavor with an associated investment of 506 thousand euros aimed to correct the signs of instability in critical zone minimizing the risks of sliding.
In order to reduce the impact of the intervention on the landscape it was foreseen the placement of vegetable soil and the lining of the outer surface of the concrete wall with a stone characteristic of the zone.
The work the responsibility of the IP involved high logistics complexity work in a difficult to access section which had the support of a maritime platform pulled by a tug for transportation and help to the development of the work namely the execution of microastacas.
Given the risks inherent in the existence of slopes-a geotechnical element that accompanies wide extended via-ferre-and supported by permanent monitoring and monitoring IP has developed several slope stabilization interventions with special focus on lines where this risk is more pronounced seeking to correct signs of instability and minor the natural risks that are intrinsically associated benefiting the safety conditions and consequently the availability and reliability of the railway infrastructure.
