Definitions

  • the invention relates to a method for laying a web in a submerged condition, comprising wrapping said web onto a drum, navigating the drum so charged to the beginning of the entrenchment after which unwinding and attachment of the web takes place.
  • the invention tends to provide a solution for the above problem. According to the invention this is achieved in that the web is formed by cutting lengths of web material to size and connecting the lengths together along lines parallel to the center line of the drum, that the web is wrapped around the drum while it is floating in the entrenchment or in a water course which is in open connection with the entrenchment, and that the drum remains floating during the laying of the web on the entrenchment.
  • the unwinding of the web is effected by pumping water from the entrenchment at the location where the web has still to be laid, to the location between the beginning of the entrenchment and the drum.
  • connection of the web edge to structure parts positioned under the water level is effected by clamping units which are lowered along guide cables, such as known from Dutch patent specification -G-94410, the invention is further characterized in that the connection fold at the end of the web being folded back along the web, already applied, by creating an overpressure relative to the ground water.
  • This overpressure can be assisted by a sausage-like ballast.
  • An apparatus for bringing into practice the invented method is characterized in that the apparatus comprises a floating drum mounted for rotation about its axis by pivotal moment arms, connected to at least one pontoon, said at least one pontoon being provided with winches to navigate the drum into the correct position.
  • the length of the drum should preferably be substantially equal to the resultant width of the entrenchment to avoid the necessity to fold the web on the drum.
  • the equipment shown in fig. 1 and 2 comprises a working floor 1 having a length which is equal to the resultant width of the web, wound on a reel 2. Said resultant width may have a length of the order of 175 meters.
  • a drum 3 can be moored, around which the web is to be wrapped. This is effected by wrapping the complete web V, necessary for one section i.e. a part of the entrenchment between for instance two structures, including the triangle which results from a possible oblique crossing of one of the structure parts, and also the prefabricated web edges, around the drum.
  • the said entrenchment need not be rectangular in plan view, but may have any shape.
  • the drum is moored as closely as possible along the working floor, and the working floor may be over the slope 4.
  • the drum 3 can be a steel tube with a diameter of approximately 1 meter and a wall thickness of approximately 12.5 millimetres.
  • the web is very thin (order of 1 millimeter) by which only an increase in radius of some tens of centimeters is developed for an entrenchment of approximately 400 meters. With respect to the location of the working floor one can think of the bank of the entrenchment to be processed or a small channel, communicating with said entrenchment.
  • the drum 3 is designed to be connected to two small pontoons 7 via two moment arms 5, which are connected to the drum via a hydromotor 6. Said design causes the total width of the drum with pertaining parts to be approximately 2 meters larger than the length of the drum itself.
  • the pontoons are provided with winches 8, which can be controlled both with respect to their tensile force and holding force. The drum 3 can be navigated into and maintained in any position within the entrenchment with the aid of said winches.
  • the drum 3 can be navigated to the extreme corner point of the entrenchment and then the partly unwound part of the web can be drawn onto an auxiliary scaffold 10 (fig. 3), secured to a viaduct 9, and temporarily be anchored.
  • an auxiliary scaffold 10 (fig. 3)
  • the total web edge can be brought onto said auxiliary scaffold 10.
  • vertical guide cables 11 are preinstalled before the drum is navigated along the viaduct between screw eyes 13 (fig. 3 and 4), present in a concrete clamping edge 12, and the auxiliary scaffold 10. Said guide cables 11 are laced through the (not shown) ring eyes, present in the web edge. Furthermore said web edge is loaded with some ballast, with the aid of which the web edge can be lowered along the guide cables 11.
  • a barbed bar 14 (fig. 4) is planned, which should prevent the web, when passed over said barb, from sliding back. With sensors one can control whether the web edge is in the required position and if not, is brought in said position.
  • clamping unit 15 Before clamping unit 15, weighing about 1 ton, can be arranged, it has to be certain that it does not meet a web V on its way along the guide cables 11, as this will undoubtedly cause damage.
  • fig. 3 two clamping units 15 are shown, the one on the clamping edge 12, already positioned, and the unit which is shown somewhat more to the top, is on its way to be positioned next to the first one. Securing said clamping units 15 next to each other takes place by turning nuts 23 (fig. 4) over the screw eyes 13.
  • the guarantee that the web will not be damaged by the clamping units can be given by further navigating the drum 3 to a position perpendicular to the axis of the entrenchment, keeping it under control, and then introducing a slight difference in water pressure by means of pumping over water.
  • the clamping units 15 After having checked first whether the web indeed almost horizontally leaves the clamping edge 12, the clamping units 15 have a length of approximately 6 meters, can be payed out one by one from the auxiliary scaffold 10 along the guide cables 11 and tightened by divers.
  • the web can now be further payed out under a certain braking moment and braking force by pumping-over water, while care is furthermore taken that the drum will not become clamped against one of the banks.
  • pegs 17 (fig. 1), which can then be connected by wires 22 to a (not shown) ring eye, which is provided in the reinforced web edges.
  • the web has to be brought above the water and the flood verge has to be filled. This can be done by locally withdrawing the web edge from the opposite side of the portion of the entrenchment thereby enabling re-profiling the verge.
  • connection of the web at the end portion of the entrenchment takes place in a similar manner as described for the connection at the beginning of the location of a structure.
  • a difference is, however, that a water enclosure 18 (fig. 5) is introduced between the web and the bottom, i.e. under the fold, which can, however, be made to disappear by creating an overpressure relative to the ground water.
  • a sausage-like ballast could be used, at one side connected to the guide cables 11, which can then be lowered parallel to the axis of the entrenchment.
  • connection to the structure 19 (fig. 5), which does not extend through the water-level, is additionally complicated, so that one has to work from the water with a derrick barge 20.
  • the guide cables 11 can then be tensioned by means of somewhat more robust floats 21.
