Definitions

  • the present invention relates to a well wall which is tubular in shape and includes a series prefabricated wall elements, connected to each other others, made of hardened bulk material.
  • Well walls of this type are used between others for the construction of wells, in particular manholes for sewers, tunnels and analogs, these wells being mostly inserted completely or at least partially in the ground.
  • this sheath can be formed above from the ground and can be driven into the ground excavating the soil inside and below the sheath or the sheath can be formed directly in a pit already dug in the ground.
  • Wells made with wall elements prefabricated are usually round, so the wall for well is a cylindrical sheath.
  • the diameters of the wells can be different in depending on the case. It is clear that with another diameter, the sections have another curvature.
  • the subject of the invention is a wall for a shaped well. tubular which does not have these drawbacks as well than others and which can be achieved in a way relatively simple and economical.
  • This object is produced in accordance with the invention by the causes it to form a polygon and be made up wall elements connected to each other, comprising two flanks which form with each others an angle whose width therefore determines the circumscribing circumference of the wall for well.
  • the sides have a width different and for example the average flank width wide is approximately double the average width of the narrow flank.
  • the invention also relates to a wall element prefabricated, intended to be used in a wall for well according to one of the preceding embodiments, as well as a casting mold comprising partitions adjustable for the realization of this wall element whose sides have an adjustable width.
  • the well wall shown in Figure 1 is consisting of several prefabricated wall elements 1, consisting of reinforced concrete, which are fixed one to the other so as to form a sheath.
  • the circles therefore also the complete sheath, have a horizontal cross section under the shape of a polygon, in the example shown a dodecagon.
  • Each circle includes as many wall elements 1 in precast concrete there are angles and each element wall 1 is therefore formed by two sides 2 and 3 which, taken together, form an obtuse angle, in the example represented an angle less than 150 °, but which nevertheless have a different width.
  • the ratio between the average widths i.e. the widths measured midway between the outer side and the inner side of the widest side 2 and the side 3 the narrowest, is between 1.5 and 3 and is preferably equal to 2, as shown in the figures.
  • Each wall element 1 has for example a height of 2 meters. It is clear that the section transverse well, in other words the diameter of the circle which circumscribes the dodecagon formed by wall elements, depends on the width of the sidewalls 2 and 3.
  • a wall for a well is represented using a line in dots and lines which, except for the dimension of the circumference, corresponds to the wall for wells represented with a solid line.
  • the two well walls have an equal number wall elements 1 which consist of two sides 2 and 3 which together form the same angle, but with sides 2 and 3 in the wall for wells shown using a solid line are wider in the same relationship as the sides 2 and 3 of the wall for wells represented using a dotted line and in lines.
  • the diameter of the cylinder liner wall wall for wells amounts to 800 cm, while with a width of this type of 168.0 cm, this diameter amounts to 1,000 cm and, with a width of 202.6 cm, the diameter extends up to 1200 cm.
  • the wall elements 1 form a round periphery and are therefore provided in their lower edge, in their upper edge and in their edges side erect, and approximately against their side external, of a groove 4 in which is inserted a elastic sealing bead 5 for example in rubber that protrudes slightly out of the groove 4.
  • the grooves 4 in two erected side edges are connecting one to the other of two wall elements 1 placed one against the other are arranged face to face, so that the elastic sealing beads 5 which are inserted there are pressed against each other as shown in detail in Figure 3.
  • each element wall 1 is provided, against its internal side, with two cavities 6 in which anchors protrude 7 anchored in concrete. Cavities 6 of two edges side facing one another are arranged facing facing and the anchors 7 are arranged one against each other and are attached to each other using a assembly by bolts 8 as shown in Figure 3.
  • each wall element 1 is provided, against the internal side, of three identical cavities 6, more precisely two in a wide flank 2 and one in the middle of a narrow flank 3.
  • An anchor 7 also projects into each of these cavities 6.
  • the cavities 6 of the wall elements 1 arranged one above the other are arranged exactly one on top of the other and the anchors 7, which are inserted there, are also connected to each other using bolt connections 8.
  • the wall elements 1 arranged the some over the others are nevertheless mounted in the state cross; by that we mean that two narrow flanks 3 are arranged over a wide sidewall 2 and that a sidewall wide 2 is arranged over a narrow side 3.
  • the wall elements 1 are provided, on their edges the highest and most lower, centering elements which are inserted one inside the other when the wall elements 1 are placed one on top of the other.
  • the wide flank 2 can be provided, at each of its ends, a hollow or a tenon, in the example shown of a tenon 9, while the narrow flank 3 is provided, at each of its ends, with the complementary element, therefore a tenon or of a trough, in the example shown of a trough 10 as shown in detail in Figure 3.
  • Wall elements 1 provided, on their periphery, with a sealing bead 5 are placed one against the other and are connected to each other using assemblies by bolts 8 which fix the anchors 7 in their edges erect until you get a circle dodecagonal closed.
  • these latter wall elements 1 are facilitated by the tenons 9 and by the depressions 10.
  • the cavities 6 formed in the lowest edge of these wall elements are arranged just above the cavities 6 of the elements of wall 1 of the underlying circle.
  • Anchors 7 inserted in these cavities 6 are fixed to each other also via bolt connections 8, so that the wall elements 1 of circles arranged one above the other the others are also attached to each other.
  • These wall elements 1 can be produced with a single and same model of casting mold or template.
  • the part of the casting mold 11 which corresponds to a wide flank 2 is oriented horizontally and is open at its upper edge.
  • the part that matches at the narrow side 3 is oriented downwards.
  • flanks 2 and 3 are determined by the position of the partitions 13 against which form the erect edges of these sides 2 and 3.
  • partitions 13 are adjustable to adapt to the width of sidewalls 2 and 3.
  • These partitions 13 can be mounted for this purpose so that you can move around continuous in the casting mold 11 and can be moved for example using jacks or the like, the simplest being to fix these partitions 13 by places with spot welds to the rest of the mold 11. These spot welds can be easily removed by grinding and applied to another place in the casting mold 11, so that the partitions 13 take the place shown for example by a line in points and lines in figure 6.
  • the wall elements 1 can be produced by therefore relatively inexpensively and a wall for wells of any size can be built in a simple and economical way, as it approaches a well wall cylindrical shape.
  • the wall for wells can be constructed as described above in a pit dug in the ground or else it can be formed above the ground and sunk into excavating the ground.
  • cutting kits 14 which are placed on the ground and connected to each other others to get a polygonal circle with as much angles than the well wall; after which we place above the first mentioned wall elements 1 from the bottom circle of the well wall and there we go fixed for example by fixing them by welding to plates steel which were poured into the wall elements 1 of the lower circle.
  • these cutting kits 14 are constituted for example an L-shaped profile which is reinforced in places by triangular ribs and whose vertical branch extends slightly further outward than the external side of the wall elements 1.
  • These cutting kits 14 allow digging in under the wall for wells to be able to push it in easily into the ground.
  • the invention is in no way limited to the form of realization described above and represented in figures; a wall for wells of this type, an element of wall for the latter, as well as a casting mold can be produced in different variants without depart from the scope of the invention.
