Description

APPARATUS FOR THE CONTINUOUS LIFTING OF DAMS.

  The present invention relates to an apparatus for raising

continuous dikes.

  It is known that a certain number of residual materials from

  mining, metallurgical or mineral chemistry industries are eliminated

  born by deposit in selected sites.

  These deposits are formed by heaps formed by mechanical transport (belts, skips, trucks, etc.) or by hydraulic transport in

suspension in water.

  In the latter case the deposit is formed by one or more basins

  settling area delimited by dikes. In each of these basins, the pro-

  duit arrives as a solid suspended in a pipe. The pro-

  decanted and forms the deposit. The transport water is separated. The additional

  dike removal can then be carried out using the decanted material

of the settling tank.

  Two methods are possible. According to the first one stops provi-

  evening operation in the settling tank. We then use the material

  common works riel: mechanical shovel, dump crane, truck,

  bulldozer. The new dikes are made with this material. A new

  the operating cycle of the settling tank is then started.

  According to the second method, the levees are raised without taking out of service the settling tank in successive layers a few tens of centimeters thick. In this case the layers are

  formed using a "mold" sliding on the dike.

  The present invention relates to an apparatus for raising in

  continuous with a thickness h of a dike of width d of a drainage basin

  tation characterized by the fact that it comprises two rectangular frames having, a width greater than d juxtaposed aligned so that the side walls of the front and rear frames are in the extension of one another, an apron raised towards the top forming the front wall of the front frame, that the front frame is constituted at its rear part by a bar providing a rectangular opening of height h and it is divided into 2 Dar a bar parallel to the side walls of the front frame, the distance

  between this bar and the side wall of the front frame located on the outside

  laughter of the settling tank is equal to d, the rear frame is also constituted at its rear part by a bar providing an opening of the same height as the rear bar of the front frame and that it comprises two skis, one being mounted on one of the aligned side walls of the front frames and

  rear and the other on the bar dividing the front frame in half.

  The description given below of an apparatus according to the invention

  will allow a better understanding of the invention. Figure 1 is a perspective view of an apparatus

according to the invention.

Figure 2 is a plan view.

  The apparatus according to the invention consists of two rectangular frames

  gular (1) and (2) juxtaposed and aligned with a width greater than that of the upper surface of the dike. The front wall (3) of the frame (1) is constituted at its lower part by a vertical sheet (3a) and it

  is preferably formed at its upper part by a sheet (3D) incli-

  nee outwards. From Deference the side walls (4, 4 ') are also

  Lement constituted by vertical sheets (4a, 4'a) surmounted by inclined sheets (4b and 4'D). The lower edges of the sheets (3a, 4a and 4'a) are located in the same horizontal plane, as are the upper edges of the inclined sheets (3b, 4b and 4'b). The different inclined sheets (3b, 4D and 4'b) form a hopper. The vertical sheets (4a and 4'a) can be provided with slots for the passage of the water contained in the decanted substance. The fourth side of the frame (1) consists of a

  bar (5) which is for example constituted by a profile. The upper part

  lower of this bar (5) is at the same level as the upper edge of the inclined sheets (30, 4b, and 4'D) and the lower edge at the edge between the vertical sheets (3a, 4a, 4'a ) and the inclined sheets (3b, 4b and 4'b). This rim therefore leaves a rectangular free space, the height h of which, by means of the horizontal plane of the lower edges of the sheets (3a, 4a and 4'a), corresponds to the thickness of the layer of material which it is desired to add dike. The front frame (1) is divided by the parallel bar 6

  to the walls (4) and (4 '). This bar (6) keeps the ski (10) on the inside

  laughing at the pelvis. In addition, it has the advantage of making the front frame (1) more rigid. The distance d between the wall (4 ') located on the outside

  basin and the bar (6) is equal to the width of the dike. During operation-

  The part of the front frame (1) located between the bar (6) and the wall (4 ') located on the inside of the pool is above the void. The framework

  rear (2) is formed at the front by the bar (5), by the side walls

  rails (7 and 7 ') located in the extension of the side walls of the frame (1) and by a rear bar (8) the side walls (7 and 7') are

  inclined according to the shape to be given to the sides of the dike.

  The lower edge of the rear bar (8) is at the same level as

  the lower edge of the bar (6). The lower edges of the green parts

  tical (4'a and 7) rest on a horizontal ski (10). The walls (4 and 4 ', 7 and 7') are preferably triangulated by vertical plates (9) so as to make the frame more rigid. At the front of the frame (1) is a front apron (11) forming a transverse ski. Skimmers located under the front apron (11) scratch the top of the existing upper part of the dike to anchor the layer of elevation of the dike. The front apron (11) is also preferably triangulated by plates

  vertical (9 ') so as to make it more rigid.

  The levee raising device is towed using cables by a crawler excavator or a crawler crane. The shovel or crane takes the material from the settling tank, drains it and introduces it into the frame (1) of the device. The mold having a width greater than the

  width a of the dam part of the material falls from the inner side to the bottom

  sin so as to form a slope having the slope angle of the material used.

  The outer side of the basin is molded at the angle determined for the outer wall of the settling basin. The apparatus according to the present invention therefore makes it possible to maintain the angles of the sides of the dam and the width of the dam. When the mold is full and the material sufficiently compacted, the device is slid over the surface of the dike to be raised over a length equal to the length of the frame (1). The levee is raised in successive layers without taking the basin out of service

decantation.

  It goes without saying that the present invention has not been described and shown

  felt that as a preferential example and that we can provide

  technical valences in constituent elements without going out

of his frame.
