Definitions

  • ABSTRACT A method of and an apparatus for filling a tube .or a hose with a solid material, such as sand, preferably for preparing a solid sausage-like member for coast protection or the like in which a liquid, preferably water, by a water pump or other pressure source is transported in a continuous flow through the tube or hose being fed from one end of the tube or hose and escaping partly or fully from the other end.
  • the solid material, preferably sand is fed to the feed line between the pump or other pressure source and the tube or hose to be filled or to the inlet end of this.
  • the flow rate of the liquid is varied in such a manner that as the area of flow owing to sedimentation of the solid material in the tube or hose is reduced the rate of flow is still kept substantially within the range in which sedimentation of the solid material will take place.
  • the invention relates to a method of and an apparatus for filling a tube or a hose with a stony, granular, pulverulent or granulated, solid material, preferably sand, by means of a carrier medium, such as water, in which the material is insoluble.
  • the present invention is concerned with a method in which the solid material is transported by a carrier medium through the tube to be filled lying in full length so that the solid material is gradually sedimented through out the length of the tube whereas the carrier medium is discharged substantially through an opening at the remote end of the tube or hose. It has, however, been found difficult to carry out this method since, if the solid material is sand and the carrier medium water, use has to be made of a sand pump which can only be regulated within certain narrow limits, and the rate of flow through the tube or hose to be filled must not be so great that there will be no sedimentation of the solid material. If, for example, the material involved is ordinary beach sand suspended in water, there will be no appreciable sedimentation if the rate of flow exceeds about 2 1/2 111 per second.
  • An essential feature of the invention is that a flow of the carrier medium is provided through the tube or pipe to be filled, by means of a pump or other source of pressure, the solid material being added to the carrier medium after the pump or pressure source and prior to or directly after its introduction into the tube or hose, the flow rate of the carrier medium being varied in such manner that as the area of flow owing to sedimentation of material in the tube or hose to be filled is reduced the rate of flow is still substantially within the range in which sedimentation will take place.
  • a pressure source adapted solely for this purpose so that, if the carrier medium is water, an ordinary water pump may be used.
  • this source of carrier medium there is provided a flow through the tube or hose to be filled.
  • the solid material for example sand, in a desired dosage, and by regulating the flow of the carrier medium through the tube or hose it becomes possible to control the sedimentation of solids in the hose in such manner that it is continued, even after the flow area having become very small, so that a complete filling or packing of the tube or hose becomes possible.
  • the tube or hose to be filled is at first filled with a carrier medium, simultaneously with a pressure above atmospheric being established which, if the hose is soft, provides and maintains the desired cross-section, for example a circular cross-section. Subsequently, a carrier medium to which the solid material is added is caused to flow through the hose, the said pressure being maintained until the hose is completely filled with the solid particles and thus retains its form.
  • a carrier medium to which the solid material is added is caused to flow through the hose, the said pressure being maintained until the hose is completely filled with the solid particles and thus retains its form.
  • An essential feature of the said apparatus is that is consists of a pressure pipe for the carrier medium, the said pressure pipe connecting a pump or a source of pressure with one end of the tube or hose to be filled, and a feed pipe connecting a tank for the solid material with the pressure pipe between the pump or the pressure source and the tube or hose to be filled or the end of the tube or hose.
  • Such an apparatus may consist of comparatively few and rather cheap components which can easily be transported and installed at the place of work.
  • FIG. 1 is a diagrammatic representation of the apparatus, viewed from the side, and
  • FIGS. 23 are the same, showing modified embodiments.
  • a tube or hose 1 is placed on a permanent support 2, for example the sea bottom, and the tube 1 may consist of a flexible porous material, for example woven plastic, or it may be impenetrable to water, made, for example, of a plastic foil.
  • the tube or hose 1 may be adapted for coast protection and be comparatively long, say 25 m, and the present invention is concerned with a method of filling such a tube or hose with a solid material in granular state, more particularly sand, so that it is packed densely in the tube, and, in the case of a hose, so that a specific cross-section is obtained.
  • a discharge pipe 3 which serves to establish a counter pressure.
  • the discharge pipe 3 may be directed upwards and/or be provided with regulating means, for example valve means, by which a regulable counter pressure may be maintained in the hose 1.
  • the discharge pipe 3 may be in fixed connection with the tube or hose 1, but may also be connected with the tube or hose 1 such manner that it may be detached.
  • a feed connecting piece 4 which is connected with a feed pipe 6 for a carrier medium, in particular water.
  • the feed pipe 6 is connected to a water pump P and has further a side branch pipe 6' which is provided with a regulating valve.
  • the feed pipe 6 further communicates with a feed pipe 14 for the material to be filled in, the said pipe being connected with a tank 8 in which the material is stored. In the case of coast protection the material will usually be sand.
  • the hose or tube 1 is according to the invention filled with sand in the followingmanner:
  • the tube or hose 1 is usually arranged in the final position, for example, in a submerged position, extending at right angles outwards from a beach, that end of the tube or hose having the piece 4 being located on the beach.
  • the process is initiated by pumping water into the tube or hose 1 by means of the water pump P, so that the said tube or hose, is of soft material, adopts the desired form, say, of circular cross-section, until a predetermined pressure Has been established in the tube or hose 1, which is obtainable in various manner, among other by regulating the discharge opening 3.
  • Sand is subsequently fed from the tank 8 through the pipe 14 to the pipe 6, and the sand-mixed liquid flow is introduced into the water filled tube 1 in which sedimentation of the sand will take place, by which the area of flow is gradually restricted. Simultaneously with the said restriction a regulation is effected so that the rate of flow of the water carrying the sand through the tube or hose 1 is maintained at such value that a sedimentation of sand takes place.
  • the regulation may be effected by bypassing a certain amount of liquid through the pipe 6.
  • Fig. 2 shows a modified embodiment using a water tank 13 instead of a pump P for conveying the water
  • the said water tank 13 being put under pressure by means of a compressed air tank 12.
  • the pressure pipe 6 is connected with the tank 8 for material by means of a by-pass pipe 9 which is fitted with a valve, so that it becomes possible to introduce a larger or smaller quantity of water into the tank 8.
  • the embodiment according to Fig. 3 has in addition to the connecting piece 4 another connecting piece 5 provided on the tube or hose 1.
  • the tank 8 is connected with the piece 5 by a feed pipe 7 which is a double pipe in which the interior pipe continues as a pipe 7' connected with a liquid pump P or a pressure liquid container 13 (not shown).
  • the liquid flowing through the pipe 7 will thus carry with it the sand material from the tank 8 and Pass it directly into the tube or hose 1.
  • the carrier medium is, as previously described, fed through the pipe 6 whichis likewise connected with a pump or pressure liquid container (not shown).
  • a special advantage of the method and apparatus according to the invention is that it is easy to avoid and to overcome a blocking in the apparatus itself or in the tube or hose 1 to be filled, which constitutes a great difficulty in the known methods and apparatus.
  • any blocking can readily be eliminated by adjusting the apparatus to deliver a powerful flow of the carrier medium without addition of solid material.
  • a method of filling a tube having a feeding inlet at one end and a discharge outlet at the other end, with stoney, granular, pulverulent or granulated solid material, preferably sand by means of a carrier liquid, such as water, in which the material is insoluble, comprising the steps of circulating a flow of the carrier liquid through the tube by pressure fluid means connected to said inlet, filling the tube with said solid material by supply means arranged between the pressure fluid means and the feeding inlet, simultaneously with said solid material and controlling the flow rate of the carrier liquid whereby the area of flow due to sedimentation of the solid material being reduced and the rate of the carrier liquid being substantially within the range in which sedimentation will take place.
  • a carrier liquid such as water
  • a method as defined in claim 1 further comprising the step of regulating the flow of the carrier liquid through the discharge outlet until a predetermined pressure is obtained within said tube.
  • An apparatus for filling a tube having a feeding inlet at one end and a discharge outlet at the other end, with stoney, granular, pulverulent or granulated material, preferably sand, by means of a carrier liquid such as water, in which the material is insoluble, comprising pressure fluid means for circulating the carrier liquid from the feeding inlet to the discharge outlet of said tube; a pressure piping line connected between said pressure fluid means and said feeding inlet of said tube; a supply source of the solid material connected to said pressure piping line between said feeding inlet and said pressure fluid means for introducing said solid material simultaneously with said carrier liquid into said tube, and means adjacent said feeding inlet and said discharge outlet for varying the rate of flow of the carrier liquid through the tube in accordance with the existing flow area in the tube.
