01.BACKGROUND

EMISOR ORIENTE TUNNEL

BACKGROUND

•Mexico City valley is a closed basin without natural water outlet.

•As a matter of fact, Mexico City was originally built in a small island of the Texcoco Lake.

•Starting in the XVIIth Century, large artificial dewatering works were undertaken to avoidrecurrent flooding of the city (Auvinet, 2010).

EMISOR ORIENTE TUNNEL

BACKGROUND

Mexico City valley is a closed basin that was originally formed of five large lakes: Texcoco, Xaltocan, Zumpango, Xochimilco and Chalco.

•Diaphragm wall (total length)

• Mixed-procedure ( Diaphragm wall + conventional constructionprocedure)

•Conventional construction procedure (total length)

DEPENDING ON THE STRATIGRAPHIC CONDITIONS, THREE CONSTRUCTION PROCEDURESFOR THE CONSTRUCTION OF SHAFT ARE USED:

DIMENSIONS:

Two types of shaft:

1) Mounting Shaft Internal diameter: 16.0m Shaft: L0, L05, L10, L13 and L20

2) Service Shaft Internal diameter: 12.0m

The distance between shafts is around 2.5km, and depth varies from 28 to 160m.

EMISOR ORIENTE TUNNELRISKs

In this type of project, there are several risks associated with geologicalconditions, however, there are also constructive aspects which results in risks.Main constructives risks can be grouped in the following way:

•Geological risks. Changes in the initial geological conditions. Impact:Change in cutting tools or design of the machine

•Construction risks. Changes in the initial construction procedures. Impact:Damage to nearby structures.

•Enviromental and natural risks. Flood damages
