Special Geotechnical Works for Metro Cairo (Egypt)
Bauer Egypt was commissioned with the specialist geotechnical engineering works for 18 out of the total of 22 underground stations on Metro Line 3. Cumulated amounts of approximately 600,000 m2 of diaphragm wall (D-wall) and 58,000 m2 of silicate gel grout plugs were executed for open excavation pits. In addition to the daily challenges, particular efforts are worth highlighting: for recovering a tunnel boring machine (TBM) of the client, a diaphragm wall shaft 100 m deep using a natural clay layer acting as a bottom plug was constructed, to allow for horizontal drilling and subsequent soil freezing measures out of the shaft; also the deployment of low-headroom units to continue the D-wall works near and under existing bridges; and finally, special jet grouting works were executed at an intersection between an existing sewer and the TBM route.
