Definitions

  • the invention relates to a method of manufacturing a screen in the soil by making use of a digging device to manufacture a vertical trench in the soil with spaced apart parallel vertical walls, guiding a foil having a width corresponding to the depth of the trench from a supply roll into the trench through a vertical slot of a casing which moves through the trench with the digging device, behind the latter, and which foil leaves the slot, seen in the direction of movement of the digging device, at the rearside of said casing, and filling the foil containing trench behind the casing with filling material.
  • a method of this kind is known from e.g. NL-A 6 900 976.
  • the space between the digging chain and a cylindrical casing surrounding a foil roll which casing has a rearwardly facing slot through which the foil can move into the open trench is kept filled with bentonite.
  • Said foil surrounding casing has lateral skirts which engage the vertical side walls of the trench and have to prevent that bentonite or the like suspension penetrates passed the casing into the open trench space which is not yet or not yet completely filled with a suitable filling material.
  • This filling material has to be a dry material since a liquid, such as cement mortar, would penetrate through the slot of the casing into the interior of the casing and spoil the interior by hardening deposits.
  • Purpose of the invention is to provide a method according to which the foil can more easily move outwardly through the slot of the casing and by means of which a filling material can be supplied which supports the walls of the trench and prevents them from collapsing and simultaneously forms the final screen in combination with the foil.
  • the casing through which the foil is supplied towards the slot is kept filled with water to which has been added a viscosity increasing agent such as bentonite and that the filling material of the trench is a cement mortar liquid and that the bentonite pressure in the casing is kept higher than the cement mortar pressure on the other side of the slot.
  • the casing, which can follow immediately behind the digging device, is now according to the invention filled with the bentonite and the foil is guided through said bentonite and to this end the foil supply roll is preferably placed above the casing.
  • the foil When the foil is inside the trench having left the casing it is surrounded by the cement mortar so that no relative movements between cement mortar and foil occur and there are no frictional forces to be overcome.
  • the cement mortar keeps the walls of the trench upright and prevents them from collapsing and after hardening forms the screen in combination with the foil.
  • the method according to the present invention can be applied by making use of such a reversing rod or roller inside the bentonite filled space of the casing.
  • Cement mortar can according to the invention not penetrate into said casing and accordingly not disturb the guidance of the foil over the reversing rod or roller.
  • the drawings show a tractor 1 with tracks 2 which is movable over the soil 3.
  • Said tractor carries a digging chain 5 from an arm 4 which by means of the cylinder 6 can be lowered or raised respectively.
  • a foil supply device or casing 7 has been suspended pivotably from the arm 4 which device can swing about the pivot 8 by means of the cylinder 9.
  • This device carries a foil supply roll 10.
  • Inside the casing 7 there is a guide rod 11 placed at 45° about which the foil section moving from above downwardly is guided into a horizontal direction and accordingly extends in the direction of the vertical plane of the trench as indicated at 12.
  • the trench walls are indicated with 13 and 14.
  • the casing 7 has a slot 15 through which the foil section 12 may move outwardly.
  • a viscosity increasing agent such as bentonite
  • the viscosity of the water can be increased as well by adding glucose, starch preparations, carboxyl methyl cellulose and other means.
