摘要： A tunnel lining process and an apparatus for use in the process in the prior art are improved in order to greatly enhance a lining speed and to facilitate the work of placing concreate for lining. The improvements reside in that a pressing form for pressing a tunnel concrete lining and a side form to be positioned on the side of the pressing form opposite to an already placed concrete lining are constructed as separate bodies in distinction from the prior art. After the pressing form and the side form have been disposed along an excavated surface of a tunnel, lining concrete is placed in a space delimited by the both forms, the excavated surface and the already placed concrete lining so as to press the lining concrete onto the excavated surface to be lined. Thereafter the pressing form is displaced along the side form and in parallel to the surface to be lined, and the steps of placing lining concrete and displacing the pressing form are repeated until placing of concrete over the entire length of the side form is completed. Then the side form is displaced to the next lining region after the finally placed concrete has revealed its mechanical strength. The aforementioned steps are repeated. A tunnel lining apparatus favorably employed upon practicing the above-described process is also disclosed.
