Definitions

  • the invention relates to a method for removing a layer of soil from the bottom of a body of water according to claim 1.
  • the invention further relates to a milling device for removing a layer of soil from the bottom of a body of water, comprising a mobile carrier unit which has drive units for movement on the ground, and at least one linear guide device which is arranged on the carrier unit and is designed for slidably guiding at least one milling unit which can be inserted into the ground substantially vertically along the linear guide device for milling soil material, according to the preamble of claim 9.
  • Milling devices have long been used in specialist foundation engineering, particularly in the construction of so-called diaphragm walls in the ground. These milling devices are usually used on a prepared, level building site.
  • An underwater dredging device for extracting raw materials from a body of water comprises a dredging unit which is guided on a base frame so as to be displaceable in a horizontal direction in order to assume different dredging positions.
  • Another underwater dredging device is known from the CN 114 542 075 known.
  • Underwater mining systems are emerging. These systems employ multiple mobile mining units, from which the mined soil material is transported to floating platforms. The water is discharged into containers located underwater between the mining units and a supply vessel.
  • the invention is based on the objective of providing a method and a milling device with which an efficient removal of a soil layer on the bottom of a body of water is made possible.
  • the invention comprises a method for removing a layer of soil from the bottom of a body of water using a milling device which is placed on the bottom of the body of water.
  • the milling device has a mobile carrier unit and at least one milling unit mounted on the carrier unit, which is slidably guided by means of at least one linear guide device.
  • the milling device After being placed on the bottom of the body of water, the milling device is brought into a substantially horizontal position and aligned.
  • a substantially horizontal, flat initial surface, also called a level surface is formed with the at least one milling unit.
  • the at least one milling unit is inserted into the soil substantially vertically along the linear guide device to mill off soil material.
  • the milling device is moved onto the initial surface formed, and starting from the flat initial surface, soil is removed by vertically moving the milling unit into the soil and horizontally moving the carrier unit.
  • a fundamental aspect of the invention is to enable the reliable use and operation of a milling device, particularly a so-called diaphragm wall cutter, with a mobile carrier vehicle, even on uneven terrain, especially stepped terrain.
  • This is achieved by placing the milling device on the waterbed and aligning it into a substantially horizontal position, and then using the at least one milling unit to create a substantially horizontal, level initial surface. The milling device is then moved onto this initial surface and proceeds from this level surface. Soil is removed by vertically moving the milling unit into the ground and horizontally moving the carrier vehicle. This now allows for further, safe soil removal even in uneven and/or largely unknown underwater terrain.
  • a preferred embodiment of the invention consists in the mobile carrier device having propulsion units, each of which is adjustable in a vertical direction. After being lowered onto the riverbed, the propulsion units are adjusted vertically in a defined manner until the desired horizontal orientation of the milling device is achieved.
  • the propulsion units serve to move the milling device. First, the milling device is aligned horizontally. Then, targeted excavation and repositioning/displacing of the milling device can take place.
  • the propulsion units can have a wheeled chassis, a tracked chassis, and/or a walking mechanism.
  • the drive units are adjusted to approximately the same position.
  • the vertical adjustment can be achieved via suitable actuators, in particular vertical actuating cylinders.
  • the drive units can again be arranged at the same height.
  • an advantageous method variant consists in forming a milling slot with a milling width that is equal to or greater than the width of the carrier device of the milling unit, and in moving the milling unit stepwise into the formed milling slot.
  • Another preferred embodiment of the invention involves the milling device removing the soil layer in a step-like and/or meandering manner. Starting from the initial surface, a large area of soil layer can thus be efficiently removed. With a limited stroke of the drive units in a In a vertical direction, deeper soil layers can be removed by working downwards in a step-like fashion. Similarly, the milling device can also ascend in a step-like fashion. By using a meandering extraction method, adjacent soil areas can be removed in rows.
  • the carrier device can only be equipped with a single milling unit for removing soil.
  • a particularly efficient removal of a soil layer is achieved by having the soil removed by several milling units, which are mounted vertically and adjustable side-by-side on the carrier device.
  • a preferred embodiment of the invention provides for at least one additional removal unit to be used to remove any ridges left behind by the milling unit.
  • This additional removal unit is positioned behind the carrier device, offset from the milling unit.
  • the removal unit can be a squeegee-like removal element or cutting element that removes smaller remaining ridges, thus leveling the milled surface.
  • the additional removal unit can also be a milling unit itself with one or more driven milling wheels.
  • one or more milling wheel axes can be vertically oriented, so that a flat surface is produced by a correspondingly flat end face of the milling wheel.
  • One or more additional removal units can be arranged.
  • the additional removal unit can preferably be mounted so that it can be moved laterally, thus covering the entire milling width by shifting it. Removing soil strata also has the advantage that additional valuable material is recovered when extracting mineral resources.
  • the milling device according to the invention is characterized in that the drive units are each mounted on a chassis of the carrier device in a vertically adjustable manner and that the drive units are each adjustable in the vertical direction via an actuator.
  • a fundamental aspect of the invention is that the drive units are mounted on a chassis of the carrier vehicle in a vertically adjustable manner and can be vertically adjusted by means of an actuator.
  • a milling device in particular a so-called diaphragm wall cutter, can be used and reliably operated with a mobile carrier vehicle even on uneven terrain, especially stepped terrain.
  • the milling device according to the invention thus allows for a wider range of applications and ensures a particularly high level of operational safety, especially against tipping on uneven terrain.
  • the linear guide device can, in particular, be a mast along which the milling unit can be moved by means of a carriage along a mast guide.
  • a preferred embodiment of the invention consists in the carrier device having two longitudinal sides, with at least two longitudinally oriented drive units arranged on each longitudinal side.
  • two or more drive units are mounted on each longitudinal side, so that differences in terrain along a longitudinal direction of the device can be compensated for by vertical adjustment of the different drive units.
  • each individual drive unit is individually vertically adjustable.
  • one or more transverse drive units can be moved downwards and/or the longitudinal drive units can be moved upwards, so that the longitudinal drive units are no longer, or only minimally, in contact with the ground, thus simplifying the movement or advancement of the milling device laterally.
  • the at least one propulsion unit can be configured in any suitable way, in particular with wheels or as a walking mechanism.
  • at least one propulsion unit has a tracked undercarriage.
  • a tracked undercarriage comprises a circulating chain and is particularly suitable for off-road use.
  • a tracked undercarriage provides a relatively large contact area, so that even a high machine weight can be distributed over a relatively large contact area, resulting in a relatively low ground pressure. This protects the soil and increases the stability of the machine.
  • the tracked undercarriage can be configured on individual propulsion units or, preferably, on all propulsion units, including the longitudinally and laterally oriented propulsion units. In principle, a combination with other types of propulsion units can also be used.
  • a particularly advantageous embodiment of the invention is achieved by arranging several milling units parallel to one another, displaceable along a linear guide. By arranging two, three, or even more milling units, a relatively wide milling slot can be created efficiently. The simultaneous use of adjacent milling units thus reduces the milling time to approximately half. Arranging additional milling units can result in a further corresponding reduction in maintenance time.
  • the removal or trench width is smaller than the width of the mobile carrier unit.
  • the total milling width of the at least one milling unit is equal to or greater than the width of the carrier's undercarriage. This can be particularly advantageous when removing soil material near the surface over larger areas.
  • the mobile milling device can perform soil removal in the longitudinal direction, with the carrier unit being advanced step by step after each removal step. In this way, the milling device can independently create a level surface for positioning and moving the milling unit.
  • a further increase in flexibility is achieved by mounting the linear guide device on an upper carriage of the carrier device, which is preferably rotatably mounted on the lower carriage about a vertical axis of rotation. This allows the milling device to machine a floor area from all sides.
  • a particularly preferred underwater mining arrangement for milling soil from a body of water wherein at least one milling device according to the invention as described above is arranged.
  • the underwater mining arrangement can be operated autonomously underwater or in conjunction with a supply vessel.
  • the underwater mining arrangement is in particular the milling device, connected to the supply ship via a connecting and supply line.
  • a supply unit is provided which is connected to the at least one milling device for supplying energy and/or removing milled soil material.
  • the supply unit itself can be arranged underwater or on the water surface.
  • the individual longitudinally oriented thrust units 20 can also be rotated about a vertical axis of rotation via the respective actuator 26.
  • four thrust units 20 are arranged on each longitudinal side.
  • a linear guide device 18 can be arranged on the upper carriage 16.
