METHOD OF BUILDING A TUNNEL WITH THE USE OF A PRELIMINARY FIXTURE AND A SUBSEQUENT FIXTURE AND A DEVICE SUITABLE FOR THIS

摘要

The present invention relates to a method of laying a tunnel, in particular, to a method of laying a tunnel with the installation of both an element of internal preliminary lining or an element of external preliminary lining, and the element of a subsequent lining, and to a device for this. The tunneling method includes driving the pilot tunnel 3 in the main tunnel 2 being constructed; the formation along the radius of the drilled hole from the surface of the development of the pilot tunnel 3 to the end of the element 4 of the internal preliminary lining of the main tunnel 2 in many places in the pilot tunnel 3 to install the element 4 preliminary lining; the introduction of the element 4 preliminary lining in the drilled hole, holding the fill solution and the curing for fixing the element of the internal preliminary lining; phased tunnel penetration in the longitudinal direction along the penetration line of the main tunnel 2 and primary sprinkling of concrete onto the surface of the main tunnel; the installation of the element 5 subsequent support between the set of elements 4 of the internal preliminary support in the surface of the main tunnel, on which nabryzgbeton primary sprayed; and the connection of the element 4 of the internal preliminary lining and the element 5 of the subsequent lining with the element lamellar lining.
