Definitions

  • the present invention relates to a device for producing columns of material in the soil, in particular in the soil of waters, e.g. on the seabed.
  • a device with a deep vibrator for the production of columns of material in the ground is for example from DE 197 07 687 Cl known.
  • the 198 14 021 A1 describes a device for the production of columns of material in the soil, which has a Tiefenillerttler and connected to the depth shaker extension tube, which can be acted upon by an overpressure.
  • Upstream of the extension tube is a lock chamber having a first closure disposed between the lock chamber and the extension tube and having a second closure on a side remote from the extension tube.
  • the material to be introduced into the soil for example concrete or gravel, passes via the second closure into the first lock chamber, from where it passes into the overpressure extension pipe when the first and the second closure are closed.
  • the overpressure in the extension tube serves to counteract a water pressure at the tip of the deep vibrator and thereby expel the material at the vibrator tip.
  • Such deep vibrators are also referred to as lock vibrators.
  • the DE 198 14 021 A1 describes a device for introducing a foreign substance in soils or for compaction of the soil.
  • the device has a deep vibrator, which is coupled via an extension tube to a lock chamber.
  • the lock chamber has a lower closure between the chamber and the extension tube and an upper closure between the chamber and a funnel used to supply the material.
  • DE 30 24 791 A1 describes a device for the treatment of substandard ground having a plurality of agitator shafts driven by a drive unit so that adjacent stirrer shafts rotate in opposite directions and serve to mix a solidifying agent introduced into the ground with the subfloor.
  • the present invention has for its object to provide a device for the production of columns of material in the soil of waters, especially in waters with great depths available.
  • the apparatus comprises a first and a second material tank, which are connected to each other, and a deep vibrator for discharging material into the ground, which is connected to the second material tank on.
  • a first closure is arranged between the first and second material tanks.
  • a first supply line for supplying material and a second supply line or a pressure equalization line for effecting a pressure equalization in the first material tank is connected.
  • the deep vibrator and the first and second material tank are under water, so they are under a pressure which is higher than the air pressure at the water surface.
  • the first feed tube serves to convey the material to be introduced into the soil from a reservoir on the water surface, for example on a ship, under pressure into the first material tank.
  • the second tube which is preferably also led to the water surface, allows a pressure equalization between the air pressure at the water surface and the first material tank.
  • the pressure in the first supply line for feeding the material, such as gravel or concrete must therefore be chosen only high enough to promote the material at atmospheric pressure with sufficient speed. This pressure is usually less than 7.5 bar. The prevailing in the water ambient pressure of the first material tank is irrelevant.
  • the pressure equalization in the first material tank by means of the second line causes the first supply line to be fed to the material under atmospheric pressure first material tank can be used a hose designed for pressures sufficient for conveying material ashore. There is no need to use expensive special hoses designed for high pressures.
  • floats are preferably arranged in this area of the line.
  • At least one further closure exists between the first and second Supply line and at least a portion of the first material tank is arranged.
  • second and third shutters are disposed between the first supply line and the first material tank and between the second supply line and the first material tank, each being opened when material is supplied to the first material tank via the first supply line.
  • the first closure between the first and second material tanks can be opened, the material via the latter usually being supplied to the deep vibrator via a pipe reaching into the depth.
  • a compressor is connected to the second material tank in order to build up a pressure in the second material tank which is greater than the water pressure at the tip of the deep vibrator, whereby the material can escape at the tip of the deep vibrator.
  • the closing of the second and third shutters upon opening the first closure causes the pressure in the second material tank to be maintained - a pressure equalization takes place only with the limited volume of the first chamber instead of - so that no dirt from the soil, in which the tip of the deep vibrator is located, is sucked.
  • the compressor is also connected to the first material tank, whereby in the first material tank after closing the first and second closures, a pressure can be built up corresponding to the pressure in the second material tank.
  • the supports of the first closure between the first and second material tanks which is designed, for example, as a slide, are thereby relieved when the first closure is opened. This is particularly useful and may be necessary when working at great depths and a correspondingly large pressure in the second material tank for discharging the material is required.
  • the first material tank has a first chamber into which the first and second supply line open, and a second chamber, wherein a further closure between the first and second chamber is arranged and wherein the first closure between the second Chamber of the first material tank and the second material tank is arranged.
  • the further closure is thus arranged between the first and second supply lines and the second chamber of the first material tank. Closures between each of the supply lines and the first material tank may be dispensed with in this embodiment.
  • the first chamber of the first material tank is in this embodiment permanently under atmospheric pressure, which is generated by the pressure equalization line.
  • the second chamber of the first material tank which is separated from the first chamber by the further closure, acts as a pressure lock, into which material is introduced from the first chamber during operation with the other closure open and the first closure closed. After closing the further closure, the material passes from the second Chamber in the second material tank, via which it passes, usually via a delivery pipe, to the top of the Tiefenrüttlers and is introduced from there into the ground.
  • the amount of material that is supplied at a time to the second material tank and discharged from there into the ground determined by the volume of the second chamber, which fills completely when opening the other closure, when the volume of the in the first chamber reserved material is greater than the maximum volume of the second chamber.
  • the first closure between the first and second material tanks and / or the further closure between the first and second chambers of the first material tank are preferably designed as slides or have a displaceable closure element.
  • a first pressure compensation element between the first and second Material tank and a second pressure compensation element between the first and second chambers of the first material tank arranged.
