Definitions

  • the invention relates to a method for levelling and filling ditches, in particular when laying pipes, cables and similar, where there is established a levelled layer of fine material in the ditch, elements which require a levelled bed, such as pipes, cables and similar, are laid on the levelled layer and are covered with fine material, and the ditch is filled with coarse material.
  • the invention also relates to a device for use in levelling and filling ditches, uneven beds and similar, especially in connection with the laying of pipes, cables and similar.
  • One specific objective of the invention is to be able to carry out the heavy work of levelling in an easier manner. In addition to allowing the work to be carried out in a labour-saving fashion, it is also an objective of the invention to be able to make a considerable saving on the costly fine material or levelling material.
  • the terms fine material and coarse material as used herein may relate directly to the structure of the material, i.e., that the materials concerned are fine and coarse, but for the sake of simplicity the terms are also used herein in a wider sense, where fine material or levelling material is to comprise the costly materials, whereas coarse material is to comprise poorer quality or cheaper materials. In purely structural terms, coarse material in the sense of the invention might conceivably be more pulverised than fine material according to the invention.
  • the levelled layer of fine material in the ditch be provided by apportioned arrangement whilst dispensed coarse material is laid simultaneously at the same level and approximately or substantially alongside the levelled layer of fine material.
  • the method can be carried by using a device as mentioned above, which device is characterised in that it is constructed in the form of a box-shaped frame designed for movement over an underlying surface, having a front and a rear end and two opposing sides, where the rear end is designed to have a height-adjustable dispensing outlet for measured release of material with which the frame is filled when the frame moves forward on the underlying surface, said box-shaped frame having along its upper side wall edges surface units which can be assembled to form a roof having crossfail over the box-shaped frame.
  • the device When using the device, it is placed on the underlying surface, for example in the bottom of the ditch.
  • the height-adjustable dispensing outlet at the rear end is set in a start position and the box-shaped frame is filled with levelling material or fine material.
  • the surface units are then put in place so that they form a roof having crossfail over the frame.
  • the box-shaped frame is moved forward it will spread an even layer of fine material, controlled by the height-adjustable dispensing outlet.
  • cheaper fill coarse material
  • Coarse material spreading members may to advantage be located lateral to the dispensing outlet. These function in such a way that the coarse material, at least in the area alongside the fine material, is levelled at approximately the same height, thereby forming a base for re-positioning and movement of the box-shaped frame, when it is desirable or necessary to fill with more fine material, for example, after pipes, cables or similar have been laid on the previously laid fine material.
  • the box-shaped frame is moved through the ditch a corresponding number of times.
  • the said surface units can to advantage be hinged to the side walls of the box-shaped frame, so that they can easily be moved to and from the roof position. It is of advantage for the rear end wall of the box-shaped frame to be capable of being raised and lowered relative to the box-shaped frame, for providing the said adjustable dispensing outlet.
  • the said spreading members can to advantage be designed as lateral projections on the rear raiseable/lowerable end wall.
  • a dividing bottom can to advantage be provided parallel with the ground plane and provided with fixed or adjustable openings. This bottom is proportioned or adjusted such that no more fine material than necessary falls down for level spreading in the adjustable dispensing outlet.
  • the box-shaped frame may have suitable carrying members for supporting and facilitating/rendering possible movement of the box-shaped frame.
  • These carrying members may, for example, be in the form of simple runners, but the use of wheels, crawler belts and similar is also conceivable.
  • the device during its movement can to advantage have a device which operates the height-adjustable dispensing outlet, so that this is activated according to need in order to adjust the levelling height.
  • a device which operates the height-adjustable dispensing outlet, so that this is activated according to need in order to adjust the levelling height.
  • known laser instruments could be used.
  • the laser control can directly actuate an activation mechanism attached to the box-shaped frame. This may, for example, involve a hydraulic unit which can raise and lower the rear end wall, thereby actuating the dispensing outlet.

  • the levelling/filling of the ditch shown in Figs. 1 , 2, 3 and 6 can be carried out with a device as shown in use in Figs. 4 and 5, but before a more detailed explanation is given of the use of the device, the device itself will be described in more detail with reference to Figs. 7 and 8.

  • the box-shaped frame can now move forward in the ditch. Whilst the fine material 19 is dispensed using the edge or working edge 23 on the rear end wall 1 1 , the side projections 26,27 will effect a spreading and dispensing of coarse material 4.

Abstract

La présente invention concerne un procédé de mise à niveau ou de remplissage d'une tranchée, procédé selon lequel on emploie une couche nivelée de matériau fin associée à une couche contiguë de matériau grossier. On utilise à cet effet un dispositif ayant la forme d'un caisson et pourvu d'une extrémité postérieure réglable en hauteur (11), qui, lorsqu'elle est relevée ou abaissée, détermine la hauteur de mise à niveau d'un matériau à grains fins se trouvant dans le bâti en forme de caisson. Lorsque l'on déplace le bâti dans la tranchée, ce matériau sort du bâti, en passant sous la paroi d'extrémité se relevant et s'abaissant. Des saillants latéraux (26, 27) sur la paroi d'extrémité permettent une distribution/répartition simultanée de matériau grossier de part et d'autre de la couche de matériau à grains fins (3), une fois celle-ci mise à niveau. Tandis que le bâti en forme de caisson est déplacé vers l'avant et répand la couche de matériau à grains fins, les saillants latéraux (26, 27) permettent la répartition du matériau grossier et sa mise à niveau une fois celui-ci déposé au-dessus du matériau à grains fins. Ce bâti en forme de caisson est pourvu d'un toit (16, 17) dont le profil transversal guide la descente du matériau grossier vers les cotés. Ce toit (16, 17) est ouvrant, ce qui permet de remplir de matériau à grains fins le bâti en forme de caisson.
