Definitions
- the present invention relates to a vessel provided with a frame which is to be placed in a water wherein tools acting on the bottom under or the wall/bank of the water near the vessel can be arranged on the underside of the said frame.
- a vessel of this kind is generally known from the prior art and comprises a floating body composed of one or more pontoons, on which a heavy crane with a piling frame is mounted. This can be used to place piles into the bottom at relatively great depth.
- a vessel of this kind is used in excavation pits, in which case, after prior driving and/or sinking of pile planking sections, the bottom and the walls of the excavation pits are finished by pouring in underwater concrete, whereupon the excavation pit is pumped out and the appropriate engineering structure, such as a railway or road, is arranged therein.
- the object of the present invention is to provide a vessel which can be used to carry out all sorts of operations and to which tools can be coupled in a stable manner in order to carry out operations of this kind.
- a vessel as described above in that said frame comprises a single straight profile section and in that said vessel is provided near an extremity with a guide for receiving said profile section as well as with winch means mounted on said vessel, the cable of which winch means is connected to the profile section.
- the invention is based on the insight that it is now possible to attach the profile section or pillar to the vessel relatively firmly by means of a guide. This means that there is no longer the unstable situation of a pile-driving crane moving over a number of pontoons.
- structures other than the piling frame described above to a vertical profile section of this kind.
- a dredging device near the end of the profile section. The dredging depth can be set during the adjustment of the height of the profile section with respect to the vessel.
- the profile section is in addition provided with a carriage which can move along it, tools of this kind can easily be moved up and down without the profile section, i.e. the pillar, having to be moved up and down with respect to the vessel.
- tools of this kind can easily be moved up and down without the profile section, i.e. the pillar, having to be moved up and down with respect to the vessel.
- a guide of this kind can be achieved by providing a recess in the vessel for receiving the profile section or pillar therein.
- the profile section is, moreover, preferably provided with projections which are situated within this recess, and guide members are likewise mounted on the vessel within this recess, in order to engage on these projections.
- the profile section preferably comprises a number of part profile sections which are connected in the longitudinal direction.
- the profile section or pillar is preferably of rectangular design. This is due to the fact that in piling frames the forces essentially act in one direction, while the profile section according to the present invention is subjected to forces on all sides.
- Dredging implements of this kind preferably comprise a reclamation dredging head, a cutter, a worm wheel and the like, which can be connected to a suction device comprising a submerged pump-type structure.
- the vessel according to the invention is generally referred to by 1. It comprises a number of floating bodies 2 which are connected to one another and are not shown in more detail. Each of the floating bodies 2 is dimensioned such that they can easily be transported by road or rail to the excavation pit in question.
- the energy supply, denoted by 3, for the various winches and tools which are yet to be described and are attached to the vessel is situated on one side of the vessel.
- the operating bridge is denoted by 4, while the manoeuvring winches are denoted by 5.
- the ends of the cables connected thereto are attached at various points on land, so that the position of the vessel 1 in the excavation pit (not shown in more detail) can be defined accurately by winches.
- the profile section or pillar according to the invention is denoted by 6. It extends down to the bottom 28 and is adjustable in the vertical direction by means of a winch 11, the cable of which is connected at the end of profile section 6.
- a carriage 7 is arranged on pillar 6, to which carriage a tool can be fastened.
- An example of a tool of this kind is a dredging device 8.
- the position of the carriage with respect to the pillar can be controlled by means of a winch 9. This is attached to the top of the pillar, so that movement of the pillar with respect to the vessel has no effect on the position of the carriage with respect to the pillar.
- an auxiliary winch 10 is provided for the purpose of hoisting up, for example, tools from the carriage.
- the pillar comprises a number of elements 18 and 19 which are connected by means of a fastening 20.
- the forces are transmitted exclusively via this fastening 20, comprising two sleeve parts pressing on one another and a bolt arranged therein.
- the pillar or the profile section 6 is depicted in detail in Fig. 2. It can be seen from this figure that it is essentially rectangular.
- Box profiles 12 are arranged at the corners of the pillars 6. It can be seen from fig. 2 that two of these box profiles 12 are enclosed by a guide 15 of the carriage 7. The other two box profiles 12 are enclosed by a guide 13 arranged in the vessel. This guide 13 is situated in a recess 27 in the floating body 2.
- Both guides 13 and 15 are provided with plastic coatings, 14 and 16 respectively, in order to limit wear.
- the guide between the pillar and the vessel in particular has to meet high standards.
- Fig. 4 shows a side view of the bottom part of the pillar. It can be seen from this figure that the bottom of the pillar is provided with a baseplate 21, which also serves as a stop for the carriage 7, that is to say the carriage cannot run off the bottom of the pillar. Moreover, a locking pin 22 is present, arranged in the pillar, which pin can move into an opening made in the carriage in the lowest position thereof. Operation is carried out by means of a cable 24, which is shown. By this means, the position of the carriage with respect to the pillar can be fixed. It should be understood that various locking devices of this kind can be arranged at other positions.
- a dredging implement 8 is arranged on carriage 7 (see also Fig. 3).
- This comprises two worm parts 29 on a shaft with a discharge between them, into which discharge the inlet 30 of a centrifugal underwater pump (not shown in more detail), and more particularly a submerged pump, opens out.
- This submerged pump is arranged in casing 25, which also contains the driving motor for the submerged pump. Lines run from power supply 3 to the driving motor in casing 25 and to the driving motor(s) of the worm parts 29 and winches.
- the above-described device makes it possible to carry out a very large number of operations underwater by selecting the appropriate tool. Examples which may be mentioned here are the removal of dredged material, levelling water bottoms, cleaning walls, carrying out hoisting, pile driving and transporting activities, laying mats and casting underwater concrete.
- the dredger pump depicted here is only an example. It can be of a different design known from the prior art. It should be understood that the length of the pillar depends on the task and is dimensioned accordingly. It is possible to go down to great depths using the structure shown here. If the stability of the vessel is insufficient, it is possible to increase this stability in a simple manner by attaching more pontoons.
