Definitions

  • the invention relates to an earth pressure shield with a front working chamber formed by a partition and having a dismantling tool standing annular space is formed and from the extracted soil material can be removed with the aid of a conveying unit, at least one liquid line from a liquid compartment with level control and liquid supply being guided through the annular space to a liquid outlet open to the removal tool.
  • the partial wall forms a stiffening annular space with a triangular cross-section, into which soil material mixed with liquid can enter, the corresponding liquid lines being able to clog.
  • Tunnels are driven into the loose soil with the help of tunneling machines.
  • the partitioned front part of the tunneling machine is preferably filled with a liquid which is under an adjustable pressure.
  • the excavation device mainly a cutting wheel, is located in this partitioned part, with which the soil is loosened. It then falls into the support liquid and is pumped out of the partitioned area together with it and fed to a separation system. There the Soil separated from the support liquid and the support liquid pumped again into the front part of the tunneling machine.
  • This method has proven itself, especially if an immersed wall almost reaching to the bottom is installed in the partitioned part of the tunneling machine, the so-called working chamber, and an adjustable compressed air cushion for a constant pressure of the supporting fluid at the rear part, the working chamber divided by the immersed wall Local face provides.
  • the stability of the working face in a non-cohesive loose soil is only guaranteed with a constant support pressure.
  • the pressure cushion reduces pressure fluctuations that arise when the volume of the pumped support liquid enriched with soil material does not correspond exactly to the volume of the cleaned liquid that is supplied again.
  • pressure transducers are installed in the rear wall of the working chamber in order to obtain a more reliable, direct statement about the support pressure in the working chamber.
  • these pressure load cells are usually unreliable measuring instruments. They are often bridged by the relatively rigid floor material. In addition, they only provide information about the pressure in a very limited local area.
  • the invention has for its object to drive tunnels in cohesive: loose soil and thereby achieve reliable support of the working face.
  • the earth pressure shield of the type mentioned behind the working chamber or the annular space formed with a baffle as a partial wall with the help of a bulkhead in a liquid compartment in its lower part and in its upper part through an opening in the partition with the bulkhead space connected to the head region of the annular space is provided.
  • a further partitioned space is therefore created behind the working chamber which is sealed off in the front part of the tunneling machine and in which a baffle wall is arranged in particular. It is penetrated by the drive of the cutting wheel, the compressed air lock for climbing the working chamber, any mixing devices and the conveyor unit, e.g. B. a screw conveyor.
  • the lower, much larger part of this bulkhead space is filled with water or a suspension, the upper part with compressed air, which, because of the upper connection to the compressed air cushion behind the diving wall, is under the same predetermined pressure, which acts on the floor material behind the diving wall.
  • the water or the suspension leads through the compressed air-filled upper part of the bulkhead and through the compressed air cushion arranged behind the baffle in the ridge area of the front part of the working chamber.
  • the feeds of water or a suspension which supply the space through which the cutting tools pass through the cutting wheel, are also connected to the water-filled, partitioned space.
  • the compressed air cushion regulated with a given pressure ensures the same constant pressure on the floor material and behind the baffle the water or suspension in the partitioned part. Measuring and control systems ensure that the level of the soil material and that of the water are at approximately the same level.
  • the shear resistance of the floor material in the working chamber now prevents the predetermined support pressure in the compressed air cushion from being transferred to the working face, especially in the sensitive ridge area.
  • a zone of low pressure is therefore created there, into which water or suspension then flows via the pipeline from the sealed-off rear space into the ridge area of the front part of the working chamber.
  • a check valve only opens if the specified support pressure has not been reached there.
  • the water or the suspension under the specified support pressure flows into the space in front of the cutting wheel through the cutting tools via the feed lines in the cutting wheel.
  • the liquid under the specified support pressure ensures the constant support pressure at the working face.
  • the viscosity of the soil material is reduced and homogenized by the liquid which is mixed with the soil material by mixing tools.
  • the shear resistance is gradually reduced to such an extent that the pressure transfer of the support pressure from the gas pressure cushion gradually reaches the ridge area. Then the liquid flow is interrupted, it only starts again when the support pressure in the roof drops below the pressure of the gas cushion due to an increased shear resistance in the floor material.
  • the automatic pressure control through the gas pressure cushion not only ensures a constant support pressure for the working face, especially in the ridge area, but also an automatic stabilization of the soil material to be removed. Mixing and agitators behind the baffle also ensure a homogeneous mixing of the soil material with the added liquid.
  • the regulated compressed air supply is guided through the bulkheads into the bulkhead space.
  • at least one stirring unit is expediently arranged in the lower part of the working chamber behind the baffle.
  • the liquid outlet is formed by a check valve in order not to exceed a predetermined support pressure.
  • This check valve preferably consists of a perforated metal plate, which is covered on its free side with a slotted rubber or plastic plate.
  • a level control can work with the help of a conveyor unit.
  • the earth pressure shield shown in the figures initially has a front working chamber 2 formed by a partition 1, in which a removal tool 3 in the form of a cutting wheel works.
  • a baffle 4 which is connected in its foot region to the part of the working chamber 2 which has the dismantling tool 3 and is operatively connected in its head region to a regulated compressed air supply 6.
  • Extracted soil material can be removed with the aid of a conveyor unit 7 in the form of a screw conveyor.
  • Two liquid lines 8 are guided from a liquid compartment 9 with level control 10 and liquid supply 11 through the annular space 5 to a liquid outlet 12 which is open to the removal tool 3.
  • the liquid regularly consists of water or a support suspension (bentonite). Behind the working chamber 2 or the annular space 5, a bulkhead 13 is provided with the aid of a bulkhead 13, which receives or forms the liquid compartment 9 in its lower part and is connected in its upper part through an opening 15 in the partition 1 to the head region of the annular space 5 is.
  • the regulated compressed air supply 6 is guided through the bulkheads 13 into the bulkhead space 14.
  • two stirring units 17 are arranged behind the baffle 4 next to a drive axis 16 of the removal tool 3.
  • the liquid outlet 12 is formed by a check valve 18.
  • this check valve 18 is formed by a perforated metal plate 19 which is covered on its free side with a slotted rubber or plastic plate 20. If there is excess pressure in the liquid lines 8, the liquid exits through the metal plate 19 and the slotted rubber or plastic plate 20. If the back pressure is higher, it will hold slotted rubber or plastic plate 20 automatically closes the perforated metal plate 19.
  • the part of the working chamber 2 lying behind the baffle 4 is provided with a level control 21 which uses the conveying unit 7 as an actuator.
