Definitions

• the invention is related to the construction of a concrete cross beam from crossbeam segments on a sheet-pile wall to form a quay wall, and to a shell structure for the application of the cross-beam-forming material in pieces or segments with an intermittent pattern.
• the shell structure In order to procure an adequate seal between the sheet-pile wall and the shell structure, the shell structure is first pressed against the sheet-pile wall, preferably by means of a pontoon, after which the shell structure is already temporarily firmly mounted to the sheet-pile wall, before it is provided with curing cross-beam material.
• the shell structure is preferably equipped with anchoring legs, which are adjustable in length, and which extend from the shell structure to their position against the sheet-pile wall. These legs are fixed to the quay wall with heavy axes via vertical sections (through the wall of tubular poles) or with lateral welds against the tubular pole.
• This invention also relates to a quay wall consisting of a sheet-pile wall on which cross-beam segments are applied according this method.
• the support of the shell structure is obtained by means of a specific substructure, in order to achieve an almost watertight seal.
• the floor of the lower partial construction is provided with an open floor edge which is of equal form to the sheet-pile wall.
• the sheet-pile wall has to be built according to a precise and regular pattern.
• the shell structure is preferably provided with projecting and mainly among each other parallel sections with legs that are adjustable in length. These legs are extended up to their position against the sheet- pile wall, and that preferably via vertical sections and heavy axes led through the wall of tubular poles, in order to already establish a temporary fixed connection of the shell structure to the sheet-pile wall.

• Fig. 10 Views of a floor shuttering.
• the shell structure 13 serves as a temporary and reusable working and boxing platform for the cross-beam segments la.
• the shell structure 13 consists of two partial constructions, namely an upper partial construction 14 and a lower partial construction 15.
• the upper partial construction 14 is provided with a floor 16 with a floor edge 17 on which a formwork 11 and the cross-beam forming material 10 is provided for.
• the lower partial construction 15 provides for a substantially watertight connection with the sheet-pile wall 2.
• the subfloor 32 is provided with the subfloor edge 33. This subfloor edge 33 is provided as form matching to the sheet-pile wall 2.
• a pontoon 30 is provided with a counterweight 31 and forklifts 29 push - in operational condition - the shell structure 13 against the sheet-pile wall 2 and are able to finely position the floating shell structure as well in the vertical as also in the horizontal direction, as it is known from the operation of forklifts.
• the lower partial construction 15 is bounded by the floor 16 of the upper partial construction 14 and on its underside by a subfloor edge 33 of a form executed as form matching with the sheet-pile wall.
• This lower partial construction 15 is used as a functional unit for support and seal for the shell structure 13 against the sheet-pile wall 2.
• Anchoring legs 19 are provided parallel to and just under the floor 17 of the upper partial construction 14. These anchoring legs 19 can be adjusted in length and extend from the shell structure 13 up to their position against the sheet-pile wall 2. These legs 19 are fixed in vertical sections 18 to the quay wall 3 by means of heavy axes 20 led through the wall made of tubular poles 8 with side weldings against the tubular pole 8.
• anchoring legs 19 per tubular pole 8 provided for in a mirror symmetric manner on or in the wall of the tubular pole. In some places, they are preferably welded to the tubular poles 8. For these purpose, the ends of the legs 19 are provided with a vertical section 18 and a stop 34. The distance calculations which are carried out in advance provide a specific length for each leg 19 so that afterwards, only minimal adjustments are necessary.
• sealing profile 24 is triangular in cross-sectional view.
• the rubber joint 24 has a triangular profile with a total thickness of about 30 cm. This large thickness is necessary to be able to connect anywhere on the sheet-pile wall 2, taking into account the possible tolerances in the longitudinal and traverse sense.
• the rubber profile is both bonded and mechanically fixed in a UPN profile that consequently must follow the form of the sheet-pile wall 2, thus it is partially lobately bent.
• the upper partial construction 14 is provided with curing cross-beam material 10 in a formwork 11 provided of a specific floor shuttering 34.
• the floor shuttering 34 is executed as form matching with the sheet- pile wall. Between the floor 16 and the slab formwork, possibly a lifting element 35 can be provided for. It goes without saying that the position and height of the cross-beam segment la to be applied must be very exact.
• the curing cross-beam material is normally made of armoured 12 concrete.
• the shell structure 13 is constructed from a steel framework with a length of about 24m, a height of 6.00m and a maximum width of 5.20m.
• the steel framework is made from standard sections and panels of, for example, 6mm in thickness.
• the upper wider partial construction 14 is the workspace with space for a crossbeam segment la, the slab formwork 11, the staff and further necessary material.
• the lower partial construction 15 should only be accessible in possible cases of emergency or for the control of the anchoring legs 19, the rubber joints 24 and the slab formwork 11.
• This lower part 15 also provides the necessary driving horizontal water pressure in order to press in the rubber joints 24 at the bottom without further help of mechanical fasteners and with minimal intervention from divers.
• a shell structure according to the invention is characterized in that the width (br) of the lower partial construction 15 is smaller than the width (BR) of the upper partial construction 14, and is preferably smaller than half of the width BR of the upper partial construction 14.
• a floor shuttering 34 is provided as mentioned previously, positioned against the sheet-pile wall 2. This consists of six independently working modules 34a up to and including 34f. On the other side (waterside 4), there is a walking path 38 provided for the personnel, which is accessible from the mainland (landside 5) via gangways.
• the shell structure is characterized in that the shell structure is provided with at least one and preferably of two or more means 27 for the reception of the forks 28 of a forklift 29 of a pontoon 30.
• a tilting frame is provided that can rotate by means of jacks.
• a lifting frame fork
• the pontoon itself is composed of floating containers (flexifloats) which are compiled to one pontoon.
• the concrete cross-beam is then constructed from cross-beam segments la, which added in an intermittent way. First the odd segments la, 3a and then the intermediate segments 2a. As an example for a quay wall 3 according to the invention, this is built from crossbeam segments with a length of about 20m. Each segment consists of a sheet-pile wall of 6 tubular poles 8 and intermediate sheet piles 7. The cross beam 1 we get has a width of 4m and a height of about 3.5m. This cross-beam construction is anchored to the rear ground with anchor piles 36. The given dimensions are of course not limiting the invention.
• the special aspect of this invention is that the cross-beam segments la, 2a, 3a are executed alongside the waterside 4, from the water in an essentially watertight closed shell structure 13, which is suspended at the sheet-pile wall 2. Moreover, this shell structure 13 is able to bear the full bulk weight of the curing cross-beam material 10, for example concrete, and consequently functions as a formwork at the same time.
• the cross-beam segments la, 3a are intermittently executed, during which preferably frequently one cross-beam segment 2a is skipped. Afterwards, the intermediate cross-beam segments are executed with a custom shell structure 13. The warping of the shell structure 13 to a next crossbeam segment is done with a floating pontoon 30.
• the shell structure 13 is somewhat modified.
• a removable panel 39 is mounted at the open corner 26 of the sidewalls 25a on the upper partial construction 14.
• the panels 39 are removed from the sidewalls.
