摘要
Procedure for the execution of tunnels or perforations in civil works through sacrificial tunnels. The present invention proposes the execution of sacrificial tunnels so that the need for the use of support elements in the construction of any tunnel is reduced or eliminated. Thus a procedure is presented for the execution of tunnels or perforations in civil works to reduce or eliminate the use of elements of support of the terrain or rock massif characterized by the execution of a Sacrifice Tunnel, so that Sacrificial Tunnel will deform assuming the tensions and deformations caused by the weight of the ground preventing them from being transmitted to the main tunnel. The Sacrifice Tunnel, which may appear in conjunction with others, must in any case be small in diameter with respect to the main tunnel, being located a certain distance above the key of the main tunnel.
