Definitions

  • the object of the present invention is a modular structural element for supporting excavations inside rock.
  • the purpose of the present invention is to obviate the above-said disadvantages, by providing a modular element which can be applied in any geological situations of the excavation, and which is easily assemblable and easily realizable.
  • a modular structural element which comprises a curved structural shape having an "U"-­shaped cross-section, with the flanges of said structural shape being directed towards the centre of curvature, with, at the ends of said structural shape, in side-by-­side position, curved portions of structural shape with "U"-shaped cross-section with flanges directed towards the centre of curvature being stably joined, furthermore on the end sections of said structural shape and of said portions of structural shape, stiffening plates being provided, and both of them being provided with through slots on their flanges, and on the stiffening plates.
  • a structural element according to the present invention is generally indicated, which is constituted by a curved "U"-shaped structural shape 11, extending along an arc of a circumference, with its flanges being directed towards the centre of curvature, with which curved portion of an "U"-shaped structural shape 12 are stably joined, e.g., by welding.
  • the portions 12 are located in the nearby of the ends of the structural shape 11 in a side-by-side position to the same structural shape, and extend by a length equal to one fourth of the length of the same structural shape.
  • both the structural shape 11 and the portions 12 are provided, on their respective end sections, with stiffening plates 14, whilst slots 15 are provided both on the flanges and on the stiffening plates 14 of the structural shape 11 and on the portions 12, in order to make it possible to fasten a plurality of structural elements to one another.
  • the modular structural element 10 Given the particular configuration of the modular structural element 10, one can easily understand how it can be coupled in the most different configurations according to the characteristics of the rock concerned by the excavation, i.e., according to the necessary lining type.
  • the selection is subordinated to the characteristics of the rock concerned by the excavation which one wants to line.
  • FIG. 12-13 shows a further application from the very many which are possible in the assemblage of these elements, in as much as in this case a ring is assembled, which is composed by 18 elements, and which constitutes a distinct supporting structure, which is installed at regular distances, which are determined according to the characteristics of the rock; in this case too, a considerable saving is achieved in installation times and in material; savings which, however, to not endager the safety of the whole structure.
  • both partial and total linings can be carried out, as they are respectively necessary in case of cost savings (favourable geological situations) and in case of particularly difficult geological situations.
