El Tingo Bridge

Key data

It includes the construction of a bridge with a concrete arch, which crosses the San Juan River ravine.

System implemented

Comprehensive steel construction service: Supply, industrial fitting out of reinforcing steel, and installation of the steel already sized “in situ”, of the various structures which made up the work.

• The bridge is located between two steep sloped mountains. For its foundations, the abutment on the right bank was piled, while the abutment on the left bank was built with direct ground foundations.
• The abutments were built on top of the foundations; these are vertical structures made up of six thirteen-metre-high piles, the piles are interlocked by means of beams which brace and strengthen these pilings.
• Two cantilevered metal arches were supported on the lower part of the abutments, which were installed in their final position by means of provisional cable-staying. The formwork for the four longitudinal concrete beams, which made up the concrete arch, was installed on the upper part of these arches.
• On the longitudinal concrete beams, were emerged piles the final height of which was the height of the deck. The emerging piles were braced together by means of transverse beams.
• The bridge deck was forged on the upper part of the abutments and the piers emerging from the arch.
