Underground line V. A – Motol station, abutment wall and securing of a foundation pit for the excavated Motol station structure (SO 09-20/01, 02)

The underground station Motol on the V.A line (section SOD 09) was designed in a slope adjacent to Kukulova Street, north of Mo-tol Hospital. It was necessary to eliminate ground pressure acting from the adjacent slope on the monolithic reinforced concrete structure of the station and therefore this slope had to be secured along its full length on the north side by a permanent anchored diaphragm wall (SO 09-20/01).The foundation pit for the station itself (SO 09-20/02) was secured on the remaining sides by the following types of constructions: the diaphragm wall continued with an anchored pile wall, anchored rider bracing was used on the southern side, the eastern side of the foundation pit with the driven tunnel portal was carried out as an anchored slope secu-red with shotcrete and a reinforcing grid, and finally the western foundation pit side was sloped into the adjoining foundation pit used as an excavated construction site for track turning tunnels. Works on this section also included securing driven tubes with micropile umbrellas.
