PROCEDURE FOR THE CONSTRUCTION OF CROSS PASSAGES IN DOUBLE PIPE TUNNELS

摘要

The procedure for the construction of underground transport infrastructures, comprises the steps of:
excavating an underground transport tunnel comprising a first pipe and a second pipe substantially parallel to one another;making a bypass tunnel connecting the first pipe and the second pipe which comprises the sub-steps of:
introducing a launching chamber along the first pipe up to a first predefined position chosen along the longitudinal direction of the first pipe, the launching chamber being able to launch a tunnel boring machine;introducing an arrival chamber along the second pipe up to a second predefined position chosen along the longitudinal direction of the second pipe, the arrival chamber being able to receive the tunnel boring machine;excavating the bypass tunnel making the tunnel boring machine move forward from the launching chamber to the arrival chamber along a direction transversal to the first pipe and to the second pipe.

1. Procedure for the construction of underground transport infrastructures, comprising the steps of:
excavating at least an underground transport tunnel comprising a first pipe and a second pipe substantially parallel to one another; making at least a bypass tunnel connecting said first pipe and said second pipe;wherein that said making at least a bypass tunnel comprises the sub-steps of:
introducing a launching chamber along said first pipe up to a first predefined position chosen along the longitudinal direction of said first pipe, said launching chamber being able to launch at least a tunnel boring machine; introducing an arrival chamber along said second pipe up to a second predefined position chosen along the longitudinal direction of said second pipe, said arrival chamber being able to receive said tunnel boring machine; excavating said bypass tunnel making said tunnel boring machine move forward from said launching chamber to said arrival chamber along a direction transversal to said first pipe and to said second pipe.
