The Altamira Landfall pipe jacking project in Mexico has nearly been completed by Eurohinca.
The development consists of the design and construction of a 2,305 m tunnel in central Mexico using a Eurohinca microtunnel boring machine.
Prior to commencement, construction of a 100 by 85 m microtunnel platform and an 800 by 130 m temporary workspace took place.
Work began in 2017 and currently 2,244 m – or 97 per cent – of the pipe jacking tunnel has been excavated with an outside diameter of 3,200 mm.
A total of 780 jacking pipes are to be installed, each of which weighs 20 t, with the project’s double jacking frame creating a jacking force capacity of 2,800 t.
Presently, the project employs approximately 270 people each day to be on the job site and has accrued a total of 790,000 working hours with zero onsite accidents.
The project is expected to be finished by the end of 2018.
