Zusammenfassung:The invention discloses a method for bidirectional tunneling of a cable tunnel through a well shield in a limited space. A starting well is built in the middle of the tunnel; a first shield tunneling machine tunneling towards the front end point direction of the tunnel is separately launched in the launching well, the split launching stage of the first shield tunneling machine is completed when the trolleys behind the first shield tunneling machine are gradually added from the launching well till the set number is reached, and the normal tunneling stage of the first shield tunneling machine is started; and after the first shield tunneling machine completes the split starting stage, a second shield tunneling machine tunneling towards the rear end point direction of the tunnel is started in a split mode in the starting well, the split starting stage of the second shield tunneling machine is completed when the trolleys behind the second shield tunneling machine are gradually added from the starting well till the
