  Development of a new design for Metro Stations

  The concept for Brooklin Station consists of five circular intersecting shafts, with a diameter of 35m, 30m in depth, and a total excavation surface of 4250 m². Water control and management is fundamental as the entire Brooklin Station area is near a contaminated zone, making any dewatering process impossible to execute. Since the water level is near the surface, structural demand is also very significant and has to be evaluated. To be able to address all the different challenges, a new innovative design has been introduced, combining the five shaft design with a diaphragm wall executed with Hydromill, without any external anchoring. The retaining structure is comprised of a 1.0 m thick diaphragm wall, with the juxtaposed panels executed with Hydromill. Balance will be achieved by internal struts at multiple levels, optimized by the arching effects obtained from the shaft’s geometry.

This way the structural support will be achieved by a 1,0 m thick diaphragm wall, being all the juxtaposed panels executed with Hydromill.
