Definitions
- This invention concerns a fall pipe for dumping materials, in particular but not exclusively stones, onto a bottom situated under water.
- Light-weight fall pipes with a specific weight as mentioned hereinabove are difficult to reinforce when they reach large lengths.
- the invention has therefore as object to provide a new and original fall pipe, offering simultaneously the required strength and flexibility so that the stones can be dumped under good circumstances at the required place onto the bottom and at the desired depth.
- the fall pipe according to the invention is mainly composed of a series of tubular elements piled up onto one another and supported by at least two cables, which elements are arranged at both ends to fit against a corresponding end of an adjacent tubular element of said series, and comprise at both ends a flange defining together with a flange of said adjacent tubular element an annular space wherein at least one resilient sealing ring is applied between said flanges.
- the sealing ring or rings between both flanges provide for a waterproof sealing between two successive tubular elements so that there is no uncontrolled water inflow in the fall pipe. Such an inflow can now, if desired, occur in a controllable way at the top of the fall pipe. Of course, in this way no fine material can further escape between two successive elements in the fall pipe according to the invention.
- the fall pipe according to the invention further also allows a limited flexion, which is required to permit the outlet of the fall pipe to be positioned correctly.
- said flanges are provided with at least one raised edge directed towards the adjacent tubular element, with said raised edges of the flanges which are situated at two ends fitting against one another, sliding fittingly into one another.
- the invention further relates to a tubular element for constructing a fall pipe according to the invention and which shows more particularly the characteristics as indicated in claim 12.
- the fall pipe shown in these figures is composed of a series of tubular, more particularly cylindrical elements 1 piled up onto one another and supported by two or possibly more cables 2. Both ends of the cylindrical elements 1 are arranged to fit against a corresponding end of an adjacent cylindrical element 1'.
- Each cylindrical element 1 shows at its two ends a outwardly directed flange.
- these flanges are represented as upper flange 3 and lower flange 4.
- a resilient seal which consists in the here represented example of three rubber rings 6 which are mutually separated by steel rings 7 having a rectangular cross section.
- the middle rubber ring 6 is caught between two steel rings 7 while the upper and the lower rubber rings 6 are each caught between a steel ring 7 and a portion of the flanges 3, respectively 4.
- the steel rings 7 show a rectangular cross section so that the rubber rings 6 remain always in contact with the large flat side of these steel rings 7.
- the flanges 3, 4 of a cylindrical element 1, l' are provided with a raised edge 8, 9 directed towards the adjacent cylindrical element 1' and 1 respectively, and sliding fittingly into one another. Due to these edges 8, 9, it is easy to position the cylindrical elements 1, l' correctly with respect to one another and a mutual displacement of these elements 1, 1' is further avoided.
- the edges 8, 9 do not necessarily have to extend over the entire circumference of the elements 1, 1'.
- the different cylindrical elements 1 composing this fall pipe can each form two by two an angle, as shown by Figure 1.
- the rubber rings 6 On one side the rubber rings 6 will be compressed (at the left in Figure 1) and on the opposite side (at the right in the same figure) they will be released.
- At least one of the raised edges 8, 9 sliding fittingly into one another shows a bevelled contact surface with the other raised edge.
- Such bevelled contact surfaces makes sliding these edges into one another further easier.
- the upper flanges 3 are locally supported by knee pieces 20.
- the entire fall pipe structure is thus formed by different cylindrical elements 1, 1'. These elements are caught over the entire length of the fall pipe between two cables 2, which are more particularly fixed to the lowermost element of the fall pipe. As a result of the own weight of the different elements, these elements lie onto one another so that heavy connections between the different elements are not required.
- each of the flanges 3 and 4 show a notch 10 at the passage of the cables 2.
- the cables 2 are fixed in the notches 10 of the flanges 3 and 4 by making use of locking plates 11 ( Figures 2, 4, 5 and 6).
- the locking plates 11 show an inner rounding 12 having a radius adapted to the diameter of the cables 2.
- the locking plates 11 are provided with pins 13 which are applied in holes 14 provided in the upper flanges 3 for fixing these plates 11 onto the upper flanges 3. In this way, applying such a locking plate 11 can be done easily and quickly, after the cable 2 has been pushed in the notch 10.
- the pins 13 are automatically blocked in the holes 14 by applying a further cylindrical element 1.
- the locking plate 11 is more particularly blocked by the raised edge 8 of the lower flange 4 of the upper element 1.
- the shape of this raised edge 8 in the area of the locking plate 11 is adapted to the shape of this plate 11.
- All of the cylindrical elements 1, 1' are internally provided with a protective layer 15.
- This layer may consist of natural or synthetic rubber or a technically equivalent material.
- the thickness of the protective layer is nearly twice the thickness of the wall of the steel cylindrical elements 1, 1'.
- the resilient lining layer 15 protrudes out of the cylindrical element 1 and fits resiliently against the corresponding lining layer of an adjacent element 1' whereby a bulge may be formed locally. In this way, a good connection is obtained between both elements 1, 1'.
- the lowermost end of the fall pipe is shown in Figure 7, which end is more particularly provided with a so-called "remote operated vehicle".
- This remote controllable unit comprises a central shute which is mounted telescopically with respect to the lowermost elements of the fall pipe.
- the cables 17 By means of the cables 17, the heaving movements of the ship can be compensated for in such a manner that the device is situated at a constant distance from the bottom.
- folding supporting arms 18 On the unit are provided folding supporting arms 18 for all kinds of sensors and/or cameras.
- thrusters are provided on the unit, as already known per se.
