Abstract
Description
- The invention relates to a tube body intended as a permanent encasement for loose or lightly coherent material for forming e.g. the core of a dike, a quay, a bank reinforcement,a jetty or a breakwater, said body being made of a fabric permeable to water and impermeable to the material and comprising at least one connection tube serving as a supply inlet for a mixture of the material and water pumped into the tube and as an outlet for water, said connection tube being fastened to the tube body.
- In general the mixture of the loose or lightly coherent material, such as sand or other ground material, and water can easily be obtained by use of known pumping means, by means of which the mixture can be drawn by suction from e.g. the beds of water ways. By pumping the material into the tube body the mixture is supplied at a predetermined pressure, whereby the loose material is free to sink and the water can be discharged to the fabric.
- It is noted that the place of any outlet must be so chosen that as little of the loose material as possible is washed away together with the water to be discharged. It will be clear that this depends on, among other things, the flow velocity of the mixture of the material and water in the tube body. It will also be clear that a compromise must be sought between the most rapid possible and the most effective possible filling of the tube body.
- The tube body may be regarded as a permanent encasement or containment of the filling material.
- The tube body according to the invention is characterized in that the connection tube extends through an aperture in the tubelar body and is fastened to the inner surface of the tube body by means of a flange portion. By this is achieved that the large forces that can occur though the pumping is under pressure of the mixture are as evenly distributed as possible, whereby the chance of leakage or a tearing away of an inlet tube from the tube body is minimized.
- A very reliable and strong embodiment it that in which a reinforcing textile is situated between the inner surface of the tube body and the flange portion.
- A variant, in which the reinforcing textile is a strip which is connected at its two edges around the tube body, has moreover the advantage that the permeability to water of the wall in the region of the input is reduced, whereby the erosion, the local washing away of the ground material, is prevented. Moreover, the inlet region of the basic fabric is reinforced.
- In an embodiment that has proved to be very practical, the tube body has the characteristic that the connection tube comprises a number of flat strips joined together in the longitudinal direction of the tube.
- In this case that variant is preferred wherein each strip in integrated with a widened portion, said widened portions being connected together to form the relevant flange portion. The continuous seams ensure a good homogeneous transmission of forces and prevent leakage.
- In another embodiment the tube body has the characteristic that the form of the strips and the form of the widened portions determine the mutual orientation of the tube body and the connection tube. This orientation can be of importance, for instance, for creating a charging stream in the tube body which is directed more or less in the longitudinal directon of that tube body, or at least in the longitudinal directon of that tube body, or at least does not lie in a substantially radial directon. By this means, too, a relatively favourable distribution of forces is obtained.
- With this same background, a variant can be used which has the characteristic that a flange portion displays a portion extending under the opening in the tube body, such that during the pumping in of mixture into the tube body through the connection tube, the stream of mixture acquires a direction different from the radial direction of the tube body.
- A tube body according to the invention can be simply manufactured by a method in which the longitudinal edges of a strip of water-permeable fabric are joined together, the ends of the tube body thus formed are closed, the tube body is provided with an aperture and a connection tube is fastened to the zone around that aperture, said connection tube extending through said aperture and being fastened to the inner surface of the tube body by means of a flange portion.
- A tube body according to the inventaion can be simply fabricated by connecting together the longitudinal edges of a strip of water-permeable fabric, closing the ends of the tube body thus formed, providing the tube body with an aperture and fastening a connection tube to the zone around that aperture. In this case the bredth of the strip of fabric determines the circumference of the tube body.
- To prepare tubelar bodies of other diameters using a given breadth of fabric strip, a method can be used according which a strip of water-permeable fabric is helically wound up so that adjacent edges acquire overlapping zones, after which the overlapping zones are joined together, the ends of the thus formed tube body are closed, the tube body is provided with an aperture and a connection tube is fastened to the zone around that opening. This last method has the further advantage that the seams extend helically, so that they are relatively strong as a consequence of a flat seam construction and of a lesser loading through any change in angular position with respect to the longitudinal direction of the tube body, and the risk of tearing under the high filling-pump pressure is less than in the previously described embodiment.

After the desired filling of the section determined by these first twoconnection tubes tube body 1 after thethird connection tube 45, which can now serve as discharge tube, while the saidsecond connection tube 44 can now serve as the supply tube for mixture. This procedure can be continued until the whole tube body is filled with sand. - The pumping direction of mixture for the filling of the first section is indicated by
arrow 5, while the discharge of water is shown byarrow 6. For the filling of the second section, mixture is pumped intotube 44 in accordance with arrow 47 while water is discharged throughconnection tube 45 in accordance with an arrow 48, and so on. - When the desired extent of filling has been reached in a section, the supply tube can be worked off in a manner to be further described below.

protection flap 20 in a rolled up state. - Figure 9 shows a
connection tube 22 withflange portion 23. Theconnection tube 22 and theflange portion 23 consist of four flat, flexible parts that are joined to one another along fourseams 25 and are thus united as an entity. - The
connection tube 22 is thrust into thetube body 27 via ahole 26. In that connection zone 28 (see figure 10), thetube body 27 is reinforced by, applied to the inner surface, a strengtheningstrip 29, which is to that end also provided with ahole 30. - Figure 10 shows a partly cut-away perspective view of the total construction of the
