Definitions

  • the present invention relates to the sector of construction engineering and more particularly to the area thereof which is concerned with the lining of tunnels by means of guniting.
  • lining layers must also form a suitable support for the layer of gunite which must be able to adhere to it and therefore comprise a layer of metal meshwork which is applied externally and formed so as to allow, as mentioned, adhesion and setting of the gunite and the possibility of adaptation by means of plastic deformation to the roughness and irregularities of the surfaces to be lined.
  • Each sheet was then applied onto the walls to be treated, fixing the lateral vertical edges thereof by means of seams of quick-setting mortar.
  • the inventor of the present invention has devised a new type of lining layer in which the sheet of plastic is made from heat-sealable material and is not covered entirely by the metal meshwork.
  • the present patent application therefore relates to a lining layer as defined in the preamble of the accompanying Claim 1 and is characterized by the characterizing part of the same claim.
  • this portion 6 is superimposed with its two lateral flanks onto the metal meshwork portions 4i of both the sheets 2, 3 which are joined together by the said joint 5 and onto which it is fixed by means of known methods (ties, etc.).
  • a uniform, uninterrupted, lining layer which has an effective waterproofing action and can be easily covered by means of guniting is thus obtained.
  • the lining layer 1 shown in the Figures covers a flat wall 7. It is obvious that, since this situation exists only very rarely in reality, most of the time the lining layer 1 has an irregular profile, which is of such a nature, as already mentioned, as to adapt perfectly to the roughness and irregularities of the wall to be lined.
  • the inventor suggests using PVC sheets with a thickness of about 0.7 mm, onto which a metal meshwork having meshes with a width of 1.6 cm and made of wire with a diameter of about 1.2 mm is applied and fixed using known methods.
