Definitions

  • the object of the invention is a group of methods, structures, and engineering solutions, that make improvements on existing point-type, usually vertically arranged engineering structures, applied for soil and groundwater treatment, or for groundwater extraction or injection (wells, soil penetrating lances, etc.) in the field of soil and groundwater treatment.
  • small-diameter drainage pipes may be set into the ground in a given depth, in radial directions, thus the affected zone of the original solution could be enlarged, and/or the applicability of the original solution could be increased, and/or the original solution may be able to combine with other applications.
  • Point-type solutions are based on a tubular device (casing pipe of a drilled well, or soil penetrating lance, etc.), what is made permeable (usually by slotting), and is inserted into the ground (by drilling, forcing down, etc.). These devices are also suitable for collecting groundwater, for swallowing the handled water (reinjection), aerating the soil mass, or injecting bacterium cultures, nutrify and aerating them. Because they involve moving significantly smaller amounts of soil, point-type systems are much cheaper, then their line- or surface-type counterparts. Due to their point-type nature, they may be successfully applied in densely built-up areas.
  • the aims of raising the efficiency of the point- type technologies like the characteristic of the line-typed method's affected zone may be realized.
  • multiple phases of operation could be applied for groundwater utilizing the same engineer structure.
  • the same engineering structure may be applied for groundwater extraction, and the desiccation of the treaded water.
  • FIG. 1 is the schematic view of the system installed in the ground, before inserting a drainage pipes into the target zone.
  • Fig. 2 shows in greater detail the region around the exit point of the drainage pipe shown in fig. 1.
  • Fig. 3 shows the advance of the drainage pipe in the ground.
  • Fig. 4 illustrates how the positioned drainage pipe is used for injecting substances into the ground.
  • Fig. 5 illustrates how the positioned drainage pipe is used with vacuum.
  • the invention is based on improving the existing, basically used casing pipes, soil penetrating lances, and other fixed-structure vertical elements utilised as supporting structural elements 1 in such a manner that they include longitudinal ducts 5 that are adapted for guiding small-diameter drainage pipes 2.
  • the ducts are arranged such, that at a predetermined point of the supporting structural element 1 that corresponds to the depth of the region to be treated, an arced section 6 curving towards the outer surface of the supporting structure element 1 is disposed to prevent a curve break.
  • the small-diameter drainage pipes 2 move forward in a vertical direction in the ducts 5 under a force applied on the surface.
  • the drainage pipes 2 When they reach the arced sections 6 they change direction without breaking and continue moving in a horizontal direction 8 parallel with the radius of the supporting structural element 1.
  • Penetrating into the surrounding region 4 (soil) is subserved primarily by the configuration of the head portion 3 of the drainage pipes 2 chosen with respect to the applied pipe insertion technology (pipe jacking, drilling, pipe jacking with flushing, etc.)
  • a given section of the wall of the properly positioned drainage pipes comprises perforations 9 or is otherwise made permeable, providing that the liquid or gas fed under pressure into the drainage pipe 2 may be introduced into the surrounding region 4, or liquid or gas may be extracted 11 from the surrounding region 4 through the drainage pipes 2 with the application of vacuum.

  • the third way of implementing the inventive method can be the so-called "drilled, jacked microdrain" according to Claim 6 (this is essentially the combination of the two previous methods).
  • the head portion of the drainage pipe has a conical configuration to reduce head point resistance.
  • the surface of the drainage pipe comprises a high-pitch spiral blade, so the application of a pressuring force on the pipe will result in a slight rotating movement in the ground, which under certain circumstances provides easier penetration in the ground.
  • the fourth possible way of implementing the invention is the so-called "jacked microdrain with water flushed drill bit" according to Claims 4, 5.
  • the head portion of the drainage pipe comprises bores directed forward and in other necessary directions, through this bores high- pressure water may be introduced into the surrounding soil region.
  • the flushing water washes out, dislodges or slurries the soil in front of the drainage pipe, and the drainage pipe may easily be inserted into the dislodged soil zone thus produced.
  • continuous water flushing the drainage pipe can be positioned in the desired region.
  • valve unit should be activated according to Claim 5, for instance by closing the flush bores at the head portion of the drainage pipe, with a ball introduced therein and producing a check valve in the noise-pipe.
  • flushing water fed to the drainage pipe will enter the targeted region primarily not through the head portion but through the perforations in the wall of the drainage pipe.
  • the invention may bring about changes mainly in the field of environmental technology, but at present it is difficult to esteem its direct and indirect effects. However, some changes can be foreseen to greater or lesser extent.
  • Recirculation groundwater remediation techniques may benefit from the addition of a relatively simple cleaned water recirculation system that helps mitigate the adverse effects of water extraction and may even replace conventional desiccation methods.
  • An equally important consideration could be that with the application of the invention cleaned groundwater can be reinjected in the immediate vicinity of the target remediation zone.
  • a new method may thus be added to the group of soil leaching and soil aeration techniques utilised for in situ soil remediation methods.
  • trench type drains that require a huge amount of construction work
  • methods involving surface spraying techniques may also find a new alternative.
  • Cleaning fluids and remediated groundwater utilised for leaching may also be injected directly into the treated zone, which increases the efficacy of soil remediation and potentially reduces the amount of chemicals used.
  • the breeding stock of bacteria applied for the bioremediation of soil and groundwater may be introduced more effectively into to the region to be treated. Nutrient feeding and aeration can also become more efficient.
  • Contaminated regions located under buildings, pavements, and other engineering structures in built-up areas may become accessible to a certain extent, shortening remediation time or making remediation possible on sites hitherto inaccessible.
  • the invention may become a significant alternative solution in densely built areas, as it is expected to be feasible to apply the inventive method in constricted regions.

Abstract

L'invention concerne un groupe de procédés permettant d'introduire des tuyaux de drainage de faible diamètre (2) dans le sol jusqu'à une profondeur donnée dans des directions radiales depuis des structures d'ingénierie disposées verticalement (puits, lances de pénétration de sol, etc.) appliquées pour le traitement de sol et d'eau souterraine ou pour l'évacuation ou l'injection d'eau souterraine, lesdites structures d'ingénierie étant utilisées comme éléments structurels de support (1). Les procédés sont essentiellement caractérisés par le fait que chaque tuyau de drainage (2) comprend une partie de tête (3) conçue pour faciliter l'insertion du tuyau de drainage (2) dans la région de sol ciblée (4) et en ce que l'élément structurel de support (1) comprend des conduits de guidage (5) pour guider les tuyaux de drainage (2), chaque conduit ayant une section arquée (6) guidant les tuyaux de drainage (2) vers le sol. Une partie donnée des tuyaux de drainage (2) ainsi introduits dans la région de sol (4) possède des perforations (9) ou, sinon, est perméable, ce qui permet que des liquides ou des gaz introduits dans les tuyaux de drainage (2) peuvent entrer dans (10) le sol de la région de sol (4) à travers la section perméable. Dans le cas où les tuyaux de drainage sont mis sous vide, des liquides ou des gaz peuvent être extraits de la région de sol (4) à travers la section perméable.
